Introduction

If your doctor has mentioned potassium citrate for kidney stones, or if you have been browsing supplement aisles looking for an alkalizing mineral compound, you have probably wondered: is this actually safe for me? The answer, like most things in medicine, depends entirely on your individual health profile.

Potassium citrate is a well-established compound used both as a prescription medication and as an over-the-counter dietary supplement. In prescription form, it is primarily indicated for managing kidney stones — particularly uric acid stones and certain calcium stones — by alkalizing the urine. In supplement form, it appears in everything from powders and capsules to drops, tinctures, and concentrated extracts.

But here is the critical truth that does not always appear on supplement labels or wellness blogs: potassium citrate has serious, potentially life-threatening contraindications. These are not mild cautions to brush aside. In certain populations, taking this compound — whether in prescription tablet form or as an organic potassium citrate supplement — can cause fatal cardiac events, dangerous gastrointestinal damage, or rapid-onset medical emergencies.

This comprehensive guide covers every documented potassium citrate contraindication, explains the underlying mechanisms in plain language, addresses the questions most commonly raised in community forums and medical reviews, and gives you the knowledge to have an informed conversation with your healthcare provider.

What Is Potassium Citrate and Why Contraindications Matter

Potassium citrate is the potassium salt of citric acid. When ingested, it breaks down into potassium ions and citrate ions, both of which serve distinct physiological roles. The citrate component acts as an alkalizing agent, raising urinary pH and reducing the crystallization of certain stone-forming salts in the kidney. The potassium component contributes to cellular function, nerve conduction, and muscular activity — including the electrical activity of the heart.

This dual action is precisely what makes potassium citrate both therapeutically useful and potentially dangerous. You are not simply taking a harmless mineral salt. You are introducing a compound that directly influences serum potassium levels and urinary chemistry. When those systems are already compromised — by kidney disease, certain medications, gastrointestinal conditions, or metabolic disorders — adding potassium citrate can push the body into a dangerous imbalance.

According to the official FDA prescribing information published on DailyMed (NIH), the drug carries explicit contraindications, black-box style warnings about hyperkalemia, and detailed precautions that apply to both prescription and supplemental uses. Mayo Clinic and Drugs.com reinforce these warnings in their clinical summaries.

Understanding potassium citrate contraindications is not academic. It is the difference between a treatment that helps and one that harms.

The Complete List of Potassium Citrate Contraindications

Before diving into the details of each contraindication, here is a consolidated reference list drawn from the official FDA drug label and corroborated by major clinical references. These conditions represent absolute contraindications — situations in which potassium citrate should not be used under any circumstances without direct physician involvement and close monitoring.

Absolute Contraindications According to the FDA Label

1. Hyperkalemia or Conditions Predisposing to Hyperkalemia Any condition that impairs the body's ability to excrete potassium can cause dangerous or fatal accumulation of potassium in the blood. This includes:

• Chronic renal failure
• Uncontrolled Addison's disease (adrenocortical insufficiency)
• Severe dehydration
• Heat cramps associated with excessive sweating

2. Renal Insufficiency with Reduced Glomerular Filtration Rate The extended-release tablet formulation is specifically contraindicated when GFR falls below 0.7 ml/kg/min. At this threshold, the kidneys cannot adequately clear the potassium load introduced by the medication, and soft tissue calcification becomes a documented risk alongside hyperkalemia.

3. Peptic Ulcer Disease Potassium citrate has documented ulcerogenic potential. Patients with active peptic ulcers, gastric ulcers, or a history of ulcerative gastrointestinal disease should not use this compound, particularly in solid oral tablet form. The high local concentration of potassium near the GI mucosa can cause direct tissue injury.

4. Active Urinary Tract Infection (UTI) This contraindication surprises many people. Potassium citrate is contraindicated in patients with UTIs, especially those caused by urea-splitting organisms such as Proteus, Klebsiella, or Pseudomonas. These bacteria thrive in alkaline environments. By raising urinary pH, potassium citrate can create ideal conditions for these organisms to multiply and for struvite (infection) stones to form. This directly opposes the therapeutic intent of the medication.

5. Conditions Causing Arrest or Delay in Tablet Passage The extended-release formulation relies on controlled transit through the gastrointestinal tract. Any condition that slows or obstructs this transit poses a risk of localized high-concentration potassium exposure to the mucosa, which can cause ulceration, perforation, or bleeding. Contraindicated conditions include:

• Delayed gastric emptying (including that caused by diabetic gastroparesis)
• Esophageal compression from enlarged cardiac chambers or mediastinal masses
• Intestinal obstruction or stricture
• Esophageal motility disorders

6. Uncontrolled Diabetes Mellitus Diabetes is a contraindication primarily because of its associated complications. Diabetic patients frequently have compromised renal function, peripheral neuropathy that could mask hyperkalemia symptoms, and autonomic gastroparesis — all of which amplify the risks described above.

7. Concomitant Use of Certain Medications (see Drug Interactions section) The concurrent use of potassium-sparing diuretics and certain other agents with potassium citrate is considered a contraindication by the prescribing information.

The Hidden Danger: Hyperkalemia Can Be Silent

One of the most alarming aspects of potassium citrate contraindications is documented in the official labeling: potentially fatal hyperkalemia can develop rapidly and be completely asymptomatic. A person might feel entirely normal while their serum potassium rises to a level capable of causing cardiac arrest. This is not a theoretical risk — it is the primary reason why contraindicated use of this compound is so dangerous.

When symptoms do appear, they may include nausea, vomiting, tingling or numbness in the extremities, muscle weakness or paralysis, and irregular or abnormal heartbeat. By the time these symptoms appear, potassium levels may already be at a critically dangerous level.

---

Kidney Disease and Potassium Citrate: The Most Critical Risk

The single most important contraindication for potassium citrate is impaired kidney function. The kidneys are the primary regulators of serum potassium. Under normal conditions, excess potassium is filtered and excreted in urine. When kidney function declines — whether through chronic kidney disease (CKD), acute kidney injury, or the specific threshold of GFR below 0.7 ml/kg/min defined in the prescribing information — this excretion mechanism becomes unreliable.

Why the GFR Threshold Matters

The 0.7 ml/kg/min GFR threshold is not arbitrary. At this level of kidney function, the kidneys are operating at significantly reduced capacity. Adding a potassium load through supplementation or medication can overwhelm what remains of their excretory capacity. The result is hyperkalemia — elevated potassium in the blood — which disrupts the electrochemical gradients that regulate heart muscle contractions.

In practical terms: a person with CKD who takes potassium citrate without medical supervision is taking a genuine cardiac risk.

What About Mild Kidney Impairment?

Even mild to moderate kidney disease warrants extreme caution. While the absolute contraindication applies to the threshold defined above, any degree of reduced kidney function means that potassium handling is compromised. Healthcare providers evaluating patients for potassium citrate therapy typically require baseline kidney function testing and may require periodic monitoring of serum electrolytes during treatment.

Can I take potassium citrate if I have kidney disease? The direct answer is: not without confirmed medical evaluation. If your GFR is below the threshold defined in the prescribing information, or if you have been diagnosed with chronic renal failure, potassium citrate is contraindicated. For those with milder impairment, the decision rests with your physician based on your complete clinical picture.

Soft Tissue Calcification Risk

Beyond the hyperkalemia concern, the prescribing information specifically flags soft tissue calcification as a risk in patients with renal insufficiency who take potassium citrate. Elevated citrate levels in the context of impaired renal clearance can contribute to calcium deposits in soft tissue — a complication that adds further reason for avoiding this compound in compromised kidney patients.

Drug Interactions You Cannot Ignore

Potassium citrate contraindications extend beyond disease states into medication combinations. Several drug classes create contraindicated or seriously dangerous interactions when combined with potassium citrate.

Potassium-Sparing Diuretics

This is the most well-documented drug interaction category. Potassium-sparing diuretics reduce urinary potassium excretion — exactly the opposite effect the body needs when adding more potassium through supplementation. The combination creates a compounding effect on serum potassium levels, dramatically increasing hyperkalemia risk. The specific agents named in the prescribing information include:

• Spironolactone (commonly used for heart failure, hypertension, and hormonal conditions)
• Triamterene (found in combination diuretic products)
• Amiloride (used for hypertension and heart failure)

If you are taking any of these medications, potassium citrate is contraindicated without direct medical supervision and careful monitoring.

Anticholinergic Medications

Anticholinergic drugs slow gastrointestinal motility. When combined with extended-release potassium citrate tablets, this slowed transit increases the contact time between the concentrated potassium formulation and the GI mucosa, significantly elevating the risk of ulceration, bleeding, and perforation. Anticholinergic agents include certain antihistamines, antidepressants, bladder medications, and antipsychotics.

ACE Inhibitors and ARBs

While not always listed as a strict contraindication, combining potassium citrate with ACE inhibitors (like lisinopril, enalapril) or angiotensin receptor blockers (ARBs) warrants significant caution. Both drug classes independently elevate serum potassium by blocking aldosterone-mediated excretion. Adding potassium citrate to this picture raises hyperkalemia risk substantially, particularly in patients who also have any degree of kidney impairment.

NSAIDs and COX-2 Inhibitors

Regular use of non-steroidal anti-inflammatory drugs can reduce renal blood flow and impair potassium excretion. This functional reduction in kidney efficiency creates a secondary mechanism for potassium accumulation when potassium citrate is added.

Always Provide a Complete Medication List

Because the interaction profile of potassium citrate intersects with so many common medications, it is essential to provide your healthcare provider with a complete and current list of every drug, supplement, herb, and over-the-counter product you take before initiating potassium citrate therapy.

Special Formulations: Drops, Tinctures, Extracts, and More

One of the most important and underappreciated aspects of understanding potassium citrate contraindications is recognizing that they apply across all formulations of the compound — not just prescription tablets. The supplement market offers potassium citrate in a wide variety of delivery forms, and each one carries the same fundamental contraindications, even when the packaging does not say so explicitly.

Potassium Citrate Drops Contraindications

Liquid drop formulations of potassium citrate are popular because they are easy to administer, can be added to water or juice, and are often marketed as gentle and fast-absorbing. Some parents use drops for children. Some athletes add them to hydration routines.

However, potassium citrate drops contraindications are identical to those of any other form. The liquid delivery does not change the compound's pharmacological activity. Drops still contribute to serum potassium load. In patients with kidney disease, concurrent use of potassium-sparing diuretics, UTI, peptic ulcer disease, or uncontrolled diabetes, drops are just as contraindicated as tablets.

Additionally, because drops are absorbed rapidly and may not carry the same GI-transit-related risks as extended-release tablets, some users mistakenly assume they are universally safer. They are not. The speed of absorption can, in some cases, cause a faster rise in serum potassium.

Potassium Citrate Tincture Contraindications

Tinctures occupy a space between liquid drops and herbal-style preparations. Potassium citrate tincture contraindications mirror those of all other forms. Tinctures are typically alcohol-based or glycerin-based carrier solutions. The carrier does not modify the contraindication profile of potassium citrate itself.

If you are considering a potassium citrate tincture for urinary alkalinization or as a mineral supplement, the same questions apply: Do you have kidney disease? Are you taking potassium-sparing diuretics? Do you have an active UTI? Is your diabetes controlled? These questions determine eligibility regardless of the delivery mechanism.

Potassium Citrate Extract Contraindications

Extracts come in various concentrations, and this is where understanding becomes critical. When reviewing potassium citrate extract contraindications, you must also know the concentration of the product. Standardized extracts deliver a defined dose per serving, while non-standardized extracts may deliver variable amounts.

The potassium citrate 4:1 extract contraindications deserve specific mention. A 4:1 extract means the product is four times more concentrated than the raw material by weight. This higher concentration means that a smaller measured dose delivers a larger potassium load than an equivalent volume of non-concentrated forms. For anyone near a contraindication threshold — such as mild kidney impairment or borderline serum potassium — a 4:1 concentrated extract represents greater risk than standard formulations.

If you are evaluating concentrated extracts, always calculate the actual potassium content per serving and compare it against safe daily limits established for your specific health condition.

Organic Potassium Citrate Contraindications

The "organic" designation in supplement labeling refers to the sourcing and processing standards of the ingredients, not to any modification of their pharmacological activity. Organic potassium citrate contraindications are exactly the same as those for conventional potassium citrate. The compound's chemical structure — and therefore its effects on serum potassium, urinary pH, and the gastrointestinal tract — is identical whether it is derived from organic or conventional sources.

Marketing language around "organic," "natural," or "clean label" products can create a false impression of universal safety. A compound is not safer because it is organic. The contraindications documented in the FDA label apply to the molecule, not its sourcing.

What Real Users Are Saying: Reviews and Reddit Discussions

Community discussions about potassium citrate contraindications on platforms like Reddit and in product review sections reveal a consistent pattern of questions, misconceptions, and genuine safety concerns. Examining what real users are discussing helps contextualize the clinical information above.

Potassium Citrate Contraindications Reddit Discussions

Browsing communities focused on kidney health, chronic illness, and supplement use, several recurring themes emerge in potassium citrate contraindications Reddit threads:

"I have CKD stage 3 — can I take potassium citrate supplements for kidney stones?" This question appears frequently. The overwhelming consensus from medical professionals who participate in these threads, as well as the clinical evidence, is that CKD patients should not self-administer potassium citrate. Stage 3 CKD represents significantly reduced kidney function, and potassium management is already a clinical priority in this population. Many users report that their nephrologists explicitly prohibited potassium citrate supplementation.

"My doctor prescribed potassium citrate, but I found an OTC version — is it the same?" This is a nuanced question. Over-the-counter potassium citrate supplements are legally limited in their elemental potassium content per serving (typically to 99 mg per serving to comply with US regulations), while prescription formulations contain much higher doses. The lower OTC dose reduces — but does not eliminate — the risk for most contraindicated populations.

"I read that potassium citrate can cause UTIs to get worse. Is that true?" Yes, and multiple Reddit users with histories of recurrent UTIs confirm this experience. The alkalinizing effect of potassium citrate creates a urinary environment that supports the growth of urea-splitting bacteria. Several users report being told by their urologists to stop potassium citrate immediately upon diagnosis of a UTI.

"Can I take potassium citrate with spironolactone?" This specific combination generates concern in threads across multiple communities. Spironolactone is used for heart failure, hormonal acne, and polycystic ovary syndrome — conditions affecting large populations. When users discover they are taking a potassium-sparing diuretic concurrently with potassium citrate, the discussion typically ends with the recommendation to consult a physician immediately, as this is a documented contraindicated combination.

Potassium Citrate Contraindications Reviews

Product reviews on major supplement retail platforms also reflect safety concerns. When examining potassium citrate contraindications reviews, a few patterns emerge:

Positive reviews tend to come from individuals without the contraindicated conditions: healthy adults using low-dose supplements for urinary alkalinization, athletes managing cramping, or individuals following a physician's recommendation.

Negative or cautionary reviews frequently mention unexpected symptom development — particularly nausea, heart palpitations, and gastrointestinal discomfort — in users who were not aware of their underlying risk factors. Some reviewers note that they discontinued use after learning from their doctors that their kidney function made potassium citrate inappropriate for them.

Reviews in the "organic" and "natural" categories sometimes show users who believed the organic designation signaled a safer product and were surprised to learn that organic potassium citrate contraindications are identical to conventional versions.

The collective picture from real-world feedback strongly supports the clinical data: when contraindications are ignored — often out of lack of awareness rather than willful disregard — adverse outcomes occur. Education is the critical missing link.

How to Use Potassium Citrate Safely When You Are Eligible

Understanding how to use potassium citrate contraindications — that is, how to navigate the contraindication profile and use the compound appropriately when you are a suitable candidate — is just as important as knowing when to avoid it.

Step 1: Confirm Your Eligibility

Before beginning any form of potassium citrate, confirm with your healthcare provider that none of the absolute contraindications apply to you. This typically involves:

• A review of your complete medication list
• Baseline kidney function testing (serum creatinine, eGFR)
• Serum potassium measurement
• Assessment of GI health history
• Review of diabetes status and blood glucose control
• Urinalysis to rule out active UTI

Step 2: Choose the Right Formulation

If you are eligible for potassium citrate and are using it under medical guidance, formulation choice matters:

• Prescription extended-release tablets provide precise dosing and are appropriate for therapeutic use in kidney stone management under physician supervision
• OTC supplements in powder or capsule form provide lower doses suitable for mild urinary alkalinization in healthy individuals
• Liquid drops and tinctures offer flexibility in dosing and may be preferable for individuals with documented GI motility concerns, but require the same eligibility screening
• Concentrated extracts (including 4:1 extract formulations) should be used only with careful attention to actual elemental potassium content per serving

Step 3: Take With Food and Adequate Water

All potassium citrate formulations should be taken with meals and a full glass of water. This reduces the concentration of potassium in contact with the GI mucosa and minimizes gastric irritation risk.

Step 4: Monitor for Warning Signs

Even in eligible individuals, ongoing monitoring is appropriate. Seek medical evaluation immediately if you notice:

• Muscle weakness or unusual fatigue
• Tingling or numbness, particularly in the hands, feet, or around the mouth
• Irregular or rapid heartbeat or palpitations
• Nausea or vomiting that is new or unusual
• Difficulty swallowing tablets
• Symptoms of UTI (burning on urination, increased frequency, cloudy urine)

Step 5: Regular Follow-Up Testing

For individuals on prescription potassium citrate, periodic serum potassium testing is standard practice. Your physician will determine the appropriate monitoring interval based on your dose, kidney function, and concurrent medications.

Is Potassium Citrate Safe? A Balanced Look

The question of is potassium citrate safe — contraindications included — requires a nuanced answer. The compound is not inherently dangerous. For appropriately selected patients without contraindications, it has a well-established safety profile and provides genuine clinical benefits in reducing kidney stone recurrence. Millions of people use it in both prescription and supplement form without adverse events.

The safety concern is not with the compound itself. It is with the mismatch between who is taking it and who should be taking it.

When It Is Appropriately Safe

• Healthy adults with no kidney disease, GI disease, active UTI, or uncontrolled diabetes
• Patients under physician supervision for kidney stone management who have been evaluated for all contraindications
• Individuals taking low-dose OTC formulations who are not on interacting medications

When the Risk Outweighs the Benefit

• Patients with CKD, especially with GFR below 0.7 ml/kg/min
• Anyone on potassium-sparing diuretics
• Patients with active or recurrent UTIs
• Individuals with peptic ulcer disease or significant GI motility disorders
• Those with uncontrolled diabetes mellitus

The Supplement Market Gap

One of the most significant safety challenges is the gap between how prescription potassium citrate is regulated and how supplement forms are marketed. Prescription labeling includes full contraindication lists, black-box warnings, and required physician oversight. Supplement labeling does not carry these same requirements.

This means a person with stage 3 CKD can walk into a supplement store, read about the "kidney supporting" and "alkalizing" benefits of organic potassium citrate, and purchase it without anyone flagging the contraindication. This is a genuine public health concern, and it is why consumer education about potassium citrate contraindications matters beyond the clinical setting.

The Best Approach

The best potassium citrate contraindications management strategy is simply this: treat potassium citrate with the same seriousness whether you encounter it as a prescription drug or a supplement. The contraindication profile does not change with the packaging. If you are uncertain whether potassium citrate is appropriate for you, the right move is always to ask your healthcare provider before starting.

Frequently Asked Questions

Q: Can I take potassium citrate if I have kidney disease?

A: No, if you have chronic renal failure or GFR below 0.7 ml/kg/min, potassium citrate is contraindicated. Even mild-to-moderate kidney impairment requires physician evaluation before use. The kidneys are responsible for excreting excess potassium, and any compromise in their function raises the risk of potentially fatal hyperkalemia.

---

Q: What medications should I absolutely avoid while taking potassium citrate?

A: The primary medications to avoid in combination with potassium citrate include potassium-sparing diuretics (spironolactone, triamterene, amiloride) and anticholinergic agents. ACE inhibitors, ARBs, and regular use of NSAIDs also warrant caution and medical evaluation before concurrent use.

---

Q: Is potassium citrate safe to use during a urinary tract infection?

A: No. Potassium citrate is contraindicated during active UTI, particularly those caused by urea-splitting bacteria. These organisms thrive in the alkaline urine environment that potassium citrate creates, and continued use can worsen the infection and promote struvite stone formation.

---

Q: Are organic potassium citrate supplements safer than conventional ones?

A: No. Organic potassium citrate contraindications are identical to those of conventional potassium citrate. The organic certification refers to sourcing and processing standards, not to any modification of the compound's pharmacological properties. The contraindication profile applies to the molecule, not its origin.

---

Q: What are the signs of high potassium (hyperkalemia) I should watch for?

A: Key warning signs include muscle weakness or paralysis, tingling or numbness in the extremities or around the mouth, nausea and vomiting, an irregular or abnormal heartbeat, and unusual fatigue. Critically, hyperkalemia can also be completely asymptomatic until it reaches a fatal threshold — which is why high-risk individuals should not take potassium citrate at all, and why monitoring is important for those on prescription therapy.

---

Q: Do potassium citrate drops contraindications differ from tablets?

A: The underlying contraindications are the same. Potassium citrate drops contraindications include all the conditions listed in the prescription label: kidney disease, active UTI, peptic ulcer disease, concurrent potassium-sparing diuretics, and others. Drops may carry a lower GI ulceration risk compared to solid extended-release tablets because they do not create the same concentrated bolus against the mucosa, but the systemic contraindications — particularly hyperkalemia risk — remain fully applicable.

---

Q: Is the potassium citrate 4:1 extract more dangerous than standard potassium citrate?

A: It delivers a more concentrated dose per unit volume or weight, meaning the actual elemental potassium content per serving may be significantly higher. For anyone near a contraindication threshold — such as borderline kidney function or high-normal serum potassium — a 4:1 concentrated extract could push them into a dangerous range more easily than a standard formulation. Always calculate actual potassium content per serving before use.

---

Q: Can I use potassium citrate if I have stomach ulcers?

A: No. Peptic ulcer disease is an absolute contraindication for potassium citrate, particularly in solid tablet form. The compound has documented ulcerogenic potential, and in the context of existing ulcers, it can cause direct mucosal injury, aggravate existing lesions, or contribute to GI bleeding.

---

Q: Are there any populations for whom potassium citrate is clearly safe without medical consultation?

A: Healthy adults with no kidney disease, no GI disease, no active UTI, no uncontrolled diabetes, and no use of potassium-sparing diuretics or other interacting medications may use low-dose OTC potassium citrate supplements with a lower level of concern. However, "lower concern" does not mean "zero concern." Given the severity of potential adverse outcomes, consulting a healthcare provider before starting any potassium citrate regimen is always the recommended approach.

---

Q: Does the term "potassium citrate tincture contraindications" refer to something different from regular potassium citrate?

A: No. Potassium citrate tincture contraindications reflect the same pharmacological profile as all other forms. The tincture vehicle — typically an alcohol or glycerin base — does not alter the compound's behavior in the body. The same absolute contraindications apply.

---

Final Verdict: Who Should Avoid Potassium Citrate Entirely

After reviewing the complete contraindication profile, the clinical mechanisms, the drug interaction data, the formulation-specific considerations, and the real-world feedback from users, the answer to "when not to use potassium citrate" can be summarized clearly.

You Should Not Use Potassium Citrate If You Have:

1. Chronic renal failure or GFR below 0.7 ml/kg/min — the risk of fatal hyperkalemia is direct and documented
2. Hyperkalemia or any condition that impairs potassium excretion — including Addison's disease and severe dehydration
3. An active urinary tract infection — especially with urea-splitting organisms, where alkaline urine worsens the infection
4. Peptic ulcer disease or significant GI motility disorders — due to ulcerogenic potential and GI obstruction risk
5. Uncontrolled diabetes mellitus — due to combined risks of impaired renal function and gastroparesis
6. A current prescription for spironolactone, triamterene, or amiloride — the hyperkalemia risk from this combination is severe

You Should Proceed Only With Medical Guidance If You Have:

• Mild-to-moderate kidney impairment
• Any degree of controlled heart failure
• Diabetes that is controlled but present
• Use of ACE inhibitors, ARBs, or regular NSAIDs
• Any condition requiring regular GI medication
• A history of any of the absolute contraindications (even if currently resolved)

The Formulation Does Not Change the Rules

Whether you are considering prescription extended-release tablets, OTC capsules, potassium citrate drops, a potassium citrate tincture, organic potassium citrate powder, a concentrated potassium citrate extract, or a potassium citrate 4:1 extract — the contraindication profile is the same. The delivery vehicle changes the dose, the absorption kinetics, and the GI exposure profile, but it does not change the fundamental pharmacology of the compound.

The Bottom Line

Potassium citrate is a genuinely useful therapeutic compound for the right patients. For those patients — evaluated, screened, and monitored appropriately — it works well and is tolerated safely. But for the populations covered by its contraindications, it represents a real danger that is too often underestimated because it appears in both prescription and supplement forms.

If you are questioning whether potassium citrate is right for you, that question itself is a signal to consult your healthcare provider before purchasing or taking anything. The contraindications exist because the risks they prevent are serious. Take them seriously.
