What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 5 of its 5 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains five active ingredients: potassium, phosphorus, calcium, soy lecithin, and choline. Potassium and calcium are minerals involved in nerve and muscle function, bone health, and heart rhythm.

Soy lecithin is a phospholipid — a fat-like compound extracted from soy — and choline is a nutrient related to brain function and cell structure. The product also contains calcium phosphate as an inactive ingredient.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: supports heart health.
  • We looked for evidence on: Atherosclerosis, Cardiovascular disease (CVD), Dyslipidemia, Heart failure, Hyperlipidemia, Hypertension — and 4 related terms.
  • The strongest evidence on file: Calcium is rated "Possibly Effective" for Pregnancy-induced hypertension (Natural Medicines).
  • Also on file: Calcium is rated "Ineffective" for Cardiovascular disease (CVD), Myocardial infarction (MI).
  • Also on file: Choline is rated "Insufficient Reliable Evidence To Rate" for Cardiovascular disease (CVD), Hypertension.

The data we hold shows calcium is effective for kidney failure, indigestion (dyspepsia), low blood calcium (hypocalcemia), high potassium levels (hyperkalemia), and likely effective for osteoporosis. For soy lecithin, the evidence is limited: it's rated likely ineffective for Alzheimer's disease, and there isn't enough reliable evidence to rate it for age-related cognitive decline, liver problems related to intravenous feeding, anxiety, or bipolar disorder.

For choline, the evidence is also thin — it's rated possibly ineffective for athletic performance and there isn't enough reliable evidence for age-related cognitive decline, liver problems, or allergies. Potassium and phosphorus have no effectiveness ratings in our data.

The evidence, ingredient by ingredient Potassium Calcium Lecithin Choline

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 4 of the 4 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 4 of 4.
  • General safety write-ups exist for 4 of 4.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Potassium from food is safe, but potassium supplements can dangerously raise your blood levels, especially if you have kidney disease — use them only under medical supervision. Calcium is generally well-tolerated at recommended doses; the most common side effects are belching, constipation, diarrhea, and stomach upset.

Rare serious concerns include kidney stones and a theoretical link between very high calcium intake (over 2,000 mg daily) and prostate cancer risk, though evidence is mixed. Soy lecithin is generally well-tolerated; common side effects are stomach pain, diarrhea, bloating, and nausea — and it can trigger allergic skin reactions in people with egg or soy allergies.

Choline is generally safe at food amounts, but high-dose supplements can cause fishy body odor, diarrhea, nausea, sweating, and vomiting (adverse effects reported above 3.5 grams daily). In pregnancy and breastfeeding, potassium and calcium from food are appropriate, but use supplements only as your doctor advises; soy lecithin and choline are rated likely safe in pregnancy, though choline needs guidance during breastfeeding.

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 3 of the 4 matched ingredients can interact with medications — Choline, Calcium, Potassium.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: heart-rhythm medications; lithium.
  • For scale: 223 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking this product, check with your pharmacist if you use any HIV integrase inhibitors (dolutegravir, elvitegravir, raltegravir), the antibiotic ceftriaxone, ACE inhibitors, angiotensin receptor blockers, potassium-sparing diuretics, levothyroxine (thyroid hormone), sotalol, the vitamin D drug calcipotriene, diltiazem, or atropine. Calcium in particular has Major-severity interactions with the first three HIV drugs and should be dosed several hours apart from them or levothyroxine.

Potassium can trigger dangerously high blood levels when combined with blood pressure or diuretic medications.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Major medication interactions have been identified, and safety information is well characterized.

This product is worth considering if you need supplemental potassium, calcium, or choline and your doctor recommends it. But if you take any blood pressure medication (especially ACE inhibitors or ARBs), a potassium-sparing diuretic, an HIV integrase inhibitor, levothyroxine, or several other drugs, you need to check this product against your exact medications first — the interactions are real.

Talk to your pharmacist before starting, especially if you have kidney problems or take prescription medications.

Each ingredient & the kinds of drugs it affects

For each ingredient in Soy Lecithin Granules with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Calcium18 drug types · 168 drugs

Ceftriaxone (Rocephin)

Co-administration of intravenous calcium and ceftriaxone can result in precipitation of a ceftriaxone-calcium salt in the lungs and kidneys.
Avoid administering intravenous calcium in any form, such as parenteral nutrition or Lactated Ringers, within 48 hours of intravenous ceftriaxone. Case reports in neonates show that administering intravenous ceftriaxone and calcium can result in precipitation of a ceftriaxone-calcium salt in the lungs and kidneys. In several cases, neonates have died as a result of this interaction. So far there are no reports in adults; however, there is still concern that this interaction might occur in adults.

Likelihood Probable Evidence D
Dolutegravir (Tivicay)

Calcium seems to reduce levels of dolutegravir.
Advise patients to take dolutegravir either 2 hours before or 6 hours after taking calcium supplements. Pharmacokinetic research suggests that taking calcium carbonate 1200 mg concomitantly with dolutegravir 50 mg reduces plasma levels of dolutegravir by almost 40%. Calcium appears to decrease levels of dolutegravir through chelation.

Likelihood Probable Evidence B
Elvitegravir (Vitekta)

Calcium seems to reduce levels of elvitegravir.
Advise patients to take elvitegravir either 2 hours before or 2 hours after taking calcium supplements. Pharmacokinetic research suggests that taking calcium along with elvitegravir can reduce blood levels of elvitegravir through chelation.

Likelihood Probable Evidence B
Aluminum

Calcium citrate might increase aluminum absorption and toxicity. Other types of calcium do not increase aluminum absorption.
Calcium citrate can increase the absorption of aluminum when taken with aluminum hydroxide. The increase in aluminum levels may become toxic, particularly in individuals with kidney disease. However, the effect of calcium citrate on aluminum absorption is due to the citrate anion rather than calcium cation. Calcium acetate does not appear to increase aluminum absorption.

Likelihood Possible Evidence B
Bictegravir/Emtricitabine/Tenofovir Alafenamide (Biktarvy)

Calcium might decrease levels of bictegravir/emtricitabine/tenofovir alafenamide by reducing its absorption when taken in a fasting state.
Advise patients that bictegravir/emtricitabine/tenofovir alafenamide and calcium can be taken together if taken with food. However, if taken on an empty stomach, bictegravir/emtricitabine/tenofovir alafenamide should not be taken with, or 2 hours after, calcium containing products.

Likelihood Probable Evidence D
Bisphosphonates

Calcium reduces the absorption of bisphosphonates.
Advise patients to take bisphosphonates at least 30 minutes before calcium, but preferably at a different time of day. Calcium supplements decrease absorption of bisphosphonates.

Likelihood Probable Evidence C
Calcipotriene (Dovonex)

Taking calcipotriene with calcium might increase the risk for hypercalcemia.
Calcipotriene is a vitamin D analog used topically for psoriasis. It can be absorbed in sufficient amounts to cause systemic effects, including hypercalcemia. Theoretically, combining calcipotriene with calcium supplements might increase the risk of hypercalcemia.

Likelihood Possible Evidence B
Digoxin (Lanoxin)

Using intravenous calcium with digoxin might increase the risk of fatal cardiac arrhythmias.
Hypercalcemia increases the risk of fatal cardiac arrhythmias with digoxin. However, one retrospective analysis of clinical data suggests that intravenous calcium does not increase the risk of dysrhythmias or mortality in patients receiving digoxin.

Likelihood Possible Evidence B
Diltiazem (Cardizem, Others)

Theoretically, calcium may reduce the therapeutic effects of diltiazem.
Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation. Theoretically, calcium might increase this risk of hypercalcemia and reduce the effectiveness of diltiazem.

Likelihood Probable Evidence D
Levothyroxine (Synthroid, Others)

Calcium seems to reduce the absorption and effectiveness of levothyroxine.
Advise patients to take levothyroxine and calcium supplements at least 4 hours apart. Calcium reduces levothyroxine absorption, probably by forming insoluble complexes. Calcium carbonate supplements reduce effectiveness of levothyroxine in patients with hypothyroidism.

Likelihood Probable Evidence B
Lithium

Theoretically, concomitant use of calcium and lithium may increase this risk of hypercalcemia.
Clinical research suggests that long-term use of lithium may cause hypercalcemia in 10% to 60% of patients. Theoretically, concomitant use of lithium and calcium supplements may further increase this risk.

Likelihood Possible Evidence B
Quinolone Antibiotics

Calcium seems to reduce the absorption of quinolone antibiotics.
Advise patients to take oral quinolones at least 2 hours before or 4-6 hours after calcium supplements or calcium-fortified foods. Taking calcium at the same time as oral quinolones can reduce quinolone absorption. Calcium binds to quinolones in the gut.

Likelihood Probable Evidence B
Raltegravir (Isentress)

Calcium may reduce levels of raltegravir.
Pharmacokinetic research shows that taking a single dose of calcium carbonate 3000 mg along with raltegravir 400 mg twice daily modestly decreases the mean area under the curve of raltegravir, but the decrease does not necessitate a dose adjustment of raltegravir. However, a case of elevated HIV-1 RNA levels and documented resistance to raltegravir has been reported for a patient taking calcium carbonate 1 gram three times daily plus vitamin D3 (cholecalciferol) 400 IU three times daily in combination with raltegravir 400 mg twice daily for 11 months. It is thought that calcium reduced raltegravir levels by chelation, leading to treatment failure.

Likelihood Possible Evidence B
Sotalol (Betapace)

Calcium seems to reduce the absorption of sotalol.
Advise patients to separate doses by at least 2 hours before or 4-6 hours after calcium. Calcium appears to reduce the absorption of sotalol, probably by forming insoluble complexes.

Likelihood Possible Evidence B
Tetracycline Antibiotics

Calcium seems to reduce the absorption of tetracycline antibiotics.
Advise patients to take oral tetracyclines at least 2 hours before, or 4-6 hours after calcium supplements. Taking calcium at the same time as oral tetracyclines can reduce tetracycline absorption. Calcium binds to tetracyclines in the gut.

Likelihood Probable Evidence C
Thiazide Diuretics

Taking calcium along with thiazides might increase the risk of hypercalcemia and renal failure.
Thiazides reduce calcium excretion by the kidneys. Using thiazides along with moderately large amounts of calcium carbonate increases the risk of milk-alkali syndrome (hypercalcemia, metabolic alkalosis, renal failure). Patients may need to have their serum calcium levels and/or parathyroid function monitored regularly.

Likelihood Probable Evidence C
Verapamil (Calan, Others)

Theoretically, calcium may reduce the therapeutic effects of verapamil.
Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation. Theoretically, use of calcium supplements may increase this risk of hypercalcemia and reduce the effectiveness of verapamil.

Likelihood Probable Evidence D
Calcium Channel Blockers

Intravenous calcium may decrease the effects of calcium channel blockers; oral calcium is unlikely to have this effect.
Intravenous calcium is used to decrease the effects of calcium channel blockers in the management of overdose. Intravenous calcium gluconate has been used before intravenous verapamil (Isoptin) to prevent or reduce the hypotensive effects without affecting the antiarrhythmic effects. But there is no evidence that dietary or supplemental calcium when taken orally interacts with calcium channel blockers.

Likelihood Unlikely Evidence D
Calcium full monograph & interactions

Potassium3 drug types · 62 drugs

Ace Inhibitors (Aceis)

Using ACEIs with high doses of potassium increases the risk of hyperkalemia.
ACEIs block the actions of the renin-angiotensin-aldosterone system and reduce potassium excretion. Concomitant use of these drugs with potassium supplements increases the risk of hyperkalemia. However, concomitant use of these drugs with moderate dietary potassium intake (about 3775-5200 mg daily) does not increase serum potassium levels.

Likelihood Likely Evidence C
Angiotensin Receptor Blockers (Arbs)

Using ARBs with high doses of potassium increases the risk of hyperkalemia.
ARBs block the actions of the renin-angiotensin-aldosterone system and reduce potassium excretion. Concomitant use of these drugs with potassium supplements increases the risk of hyperkalemia. However, concomitant use of these drugs with moderate dietary potassium intake (about 3775-5200 mg daily) does not increase serum potassium levels.

Likelihood Likely Evidence C
Potassium-Sparing Diuretics

Concomitant use increases the risk of hyperkalemia.
Using potassium-sparing diuretics with potassium supplements increases the risk of hyperkalemia.

Likelihood Likely Evidence C
Potassium full monograph & interactions

Choline1 drug type · 16 drugs

Atropine

Theoretically, choline might decrease the effects of atropine in the brain.
Animal research shows that administering choline one hour before administering atropine can attenuate atropine-induced decreases in brain levels of acetylcholine. Theoretically, concomitant use of choline and atropine may decrease the effects of atropine.

Soy Lecithin Granules by Puritan's Pride: Common Questions

Does Soy Lecithin Granules by Puritan's Pride interact with any medications?
Yes. Based on its ingredients, Soy Lecithin Granules has a known interaction with 223 medications, including 7 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Soy Lecithin Granules contains 5 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is this safe to take if I'm pregnant or breastfeeding?
Potassium and calcium from food are fine in pregnancy, but only use supplements as your doctor advises. Soy lecithin and choline are both rated likely safe during pregnancy. If you're breastfeeding, choline needs are higher — talk to your provider before using a supplement, and potassium supplements should be discussed with your doctor too.
What are the most common side effects?
Potassium can cause stomach pain, belching, diarrhea, nausea, and gas. Calcium often causes belching, constipation, diarrhea, and stomach upset. Soy lecithin may cause stomach pain, diarrhea, bloating, and nausea. Choline can cause fishy body odor, especially at higher doses. All side effects are generally mild when used at recommended amounts.
Can this help with memory or brain function?
Soy lecithin and choline have been studied for Alzheimer's disease and age-related cognitive decline, but the evidence isn't strong enough to say they work. Soy lecithin is rated likely ineffective for Alzheimer's disease. There just isn't enough reliable data for either ingredient on other cognitive conditions.
Will this help my bones?
Calcium is rated likely effective for osteoporosis when used appropriately, so it may help support bone health. The other ingredients don't have effectiveness ratings for bone health in our data.
What if I have a soy or egg allergy?
Soy lecithin can trigger allergic skin reactions in people with soy or egg allergies. If you have either allergy, avoid this product or talk to your doctor first.
Can I take this if I have kidney disease?
Potassium supplements can dangerously raise your blood levels if your kidneys don't work well, so talk to your doctor before using this product. Calcium is generally okay, but your doctor should clear it given your kidney function.
