Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 8 of its 8 active ingredients.
  • “Soy Lecithin” is listed as a grouped ingredient — the label gives one combined amount (15 Gram(s)) without saying how much of each component you get.
  • “Phosphatidylcholine” is listed as a grouped ingredient — the label gives one combined amount (3.40 Gram(s)) without saying how much of each component you get.

Country Life Lecithin Granules contains 8 ingredients, including three active components: choline, potassium, and calcium. Choline is a nutrient involved in brain and nerve function.

Potassium is an electrolyte essential for heart rhythm and muscle function. Calcium supports bone health and other body functions.

The product also contains soy lecithin — a fat derived from soy that's broken down into its component parts — plus phosphatidylethanolamine, phosphatidylinositol, and phosphatidylcholine, which are phospholipids (fat compounds) found naturally in cells. There are no inactive fillers listed.

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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: support brain and nerve function.
  • We looked for evidence on: Age-related cognitive decline, Alzheimer disease, Cognitive function, Dementia, Memory, Nervous system health — and 1 related terms.
  • The closest evidence on file: Choline is rated "Insufficient Reliable Evidence To Rate" for Age-related cognitive decline (Natural Medicines).
  • Also on file: Choline is rated "Insufficient Reliable Evidence To Rate" for Alzheimer disease, Cognitive function, Dementia.

The product facts don't provide effectiveness ratings for lecithin or choline supplementation in this granule form. For calcium, the data shows it's effective for kidney failure, dyspepsia (indigestion), low blood calcium (hypocalcemia), high blood potassium (hyperkalemia), and likely effective for osteoporosis.

However, these ratings reflect calcium's use as a targeted supplement or medication, not as an ingredient in a general lecithin product. For choline specifically, the evidence on file doesn't support its use for athletic performance, and there's insufficient evidence for bronchitis, age-related cognitive decline, liver disease, hay fever, and Alzheimer disease.

The evidence, ingredient by ingredient Potassium Lecithin Phosphatidylcholine Calcium

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 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Choline is rated likely safe during pregnancy and lactation, though it's important for fetal development — follow your doctor's dosing advice rather than self-dosing. Potassium and calcium are both rated likely safe during pregnancy and lactation at recommended amounts, but potassium supplements carry a risk in certain conditions like kidney disease, where they can cause dangerously high blood levels.

At high doses (9 grams daily or more of choline), you may experience diarrhea, nausea, vomiting, sweating, salivation, or a fishy body odor. Potassium at high doses can cause abdominal pain, belching, diarrhea, flatulence, nausea, and vomiting; rare serious effects include heart arrhythmias and low blood pressure.

Calcium is generally well tolerated but can cause constipation, belching, or stomach upset; very high intakes have been linked in some research to increased prostate cancer risk and cardiovascular concerns, though this research remains debated.

Label statements
These statements are the manufacturer’s wording, reproduced from the product label — the label is saying it, not HelloPharmacist. We don’t verify or endorse them.
General Statements

Lecithin is a lipotropic substance and a natural source of phosphatidylcholine and phosphatidylinositol, two phospholipids found in the brain, as well as the essential fatty acid linoleic acid. Phospholipids, such as phosphatidylcholine, are key building blocks of cell metabolism in the liver. Choline supports homocysteine levels in the blood that are already in the normal range. Choline is essential for the production of acetylcholine, an important brain neurotransmitter.

Each ingredient & the kinds of drugs it affects

For each ingredient in 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.

Lecithin Granules by Country Life: Common Questions

Does Lecithin Granules by Country Life interact with any medications?
Yes. Based on its ingredients, 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?
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.
Does this product have any fillers or inactive ingredients?
No — according to the label information we have, there are no inactive fillers or other ingredients listed in this product.
Is it safe to take during pregnancy or while breastfeeding?
Choline, potassium, and calcium are all rated likely safe during pregnancy and lactation, but amounts matter — follow your doctor's guidance rather than supplementing on your own, especially with potassium, which can build to unsafe levels in certain conditions.
What does choline do in this product?
Choline is a nutrient that supports brain and nerve function. The evidence on file doesn't support choline supplements for athletic performance, and there isn't enough reliable data on its use for cognitive decline, Alzheimer disease, hay fever, bronchitis, or liver disease.
Can this product cause side effects?
At normal doses it's generally well tolerated, but at very high doses (especially 9+ grams of choline daily), you may experience diarrhea, nausea, vomiting, a fishy body odor, or gastrointestinal discomfort. High potassium can cause diarrhea, nausea, abdominal pain, or in rare cases, heart rhythm problems.
Why does this product have so many medication interactions?
The product contains potassium and calcium, both minerals that can form chemical bonds with certain medications and either reduce how your body absorbs them or raise your blood levels of them to unsafe amounts — that's why spacing doses apart is sometimes needed.
