Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 9 of its 9 active ingredients.
  • “Soy Lecithin Granules” is listed as a grouped ingredient — the label gives one combined amount (7.50 Gram(s)) without saying how much of each component you get.

Bluebonnet Lecithin Granules has 9 ingredients total. The active ones are potassium, magnesium, choline, phosphatidylcholine, inositol phosphatide, and soy lecithin granules — a mix of phosphorus, monounsaturated fats, and polyunsaturated fats that support cell structure and function.

The product contains no inactive fillers or binders; all nine components are meant to provide nutritional activity.

Does it work?

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: Plant-based nutritional supplement.
  • We looked for evidence on: Cognitive function, Cognitive impairment, Age-related cognitive decline, Dementia, Alzheimer disease, Liver support — and 2 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.
  • Also on file: Phosphatidylcholine is rated "Insufficient Reliable Evidence To Rate" for Alzheimer disease, Dementia.

The evidence for this product's ingredients is mixed and incomplete. Magnesium is effective for indigestion (dyspepsia), constipation, low magnesium levels (hypomagnesemia), and pre-eclampsia in pregnancy.

Phosphatidylcholine shows possibly effective evidence for ulcerative colitis, but insufficient evidence exists for its use in fatty liver disease, Alzheimer's disease, or anxiety. Inositol is possibly effective for polycystic ovary syndrome (PCOS), metabolic syndrome, and preterm labor, though it's possibly ineffective for anxiety and depression.

The evidence for choline as an athletic performance aid is insufficient or possibly ineffective, and data doesn't support use for age-related cognitive decline, liver complications of total parenteral nutrition (TPN), or hay fever. Overall, there's no single established use for this specific combination product.

The evidence, ingredient by ingredient Potassium Magnesium Choline Lecithin Phosphatidylcholine Inositol

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 5 of the 5 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 5 of 5.
  • General safety write-ups exist for 5 of 5.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Potassium is generally well tolerated from food, but supplements can cause dangerously high blood levels in some people, especially those with kidney disease — use only under medical guidance. Magnesium is generally well tolerated at recommended doses; common side effects from oral use are diarrhea, nausea, vomiting, and abdominal pain.

Choline is well tolerated at food amounts, but high-dose supplements (above 3.5 grams daily) can cause fishy body odor, diarrhea, nausea, and sweating. Phosphatidylcholine is generally well tolerated but may cause bloating, diarrhea, altered taste, nausea, and vomiting, especially at doses above 30 grams daily.

Inositol is generally well tolerated with mostly mild digestive side effects like diarrhea, gas, and nausea. For pregnancy, potassium from food is fine but supplements require medical supervision.

Magnesium is likely safe in pregnancy but use supplements only under doctor guidance. Choline is likely safe in pregnancy.

Phosphatidylcholine safety beyond food sources is not well studied in pregnancy — check with your doctor. Inositol safety in pregnancy is not fully established — use only under medical supervision.

For breastfeeding, check with your doctor before using potassium, magnesium, choline, or inositol supplements, as safety data is limited.

Major identified

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

Why this rating?
  • 4 of the 5 matched ingredients can interact with medications — Inositol, Choline, Potassium, Magnesium.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; heart-rhythm medications; Parkinson's medications.
  • For scale: 422 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.

Stop and check your medications before taking this product if you're on any of these: levodopa/carbidopa (Sinemet) — Major severity; potassium-sparing diuretics, ACE inhibitors, or ARBs for blood pressure; skeletal muscle relaxants; calcium channel blockers; sulfonylureas or other diabetes drugs; quinolone or fluoroquinolone antibiotics; or bisphosphonates for bone health. All carry Moderate-severity risks.

Choline has a Minor-severity interaction with atropine. No interactions are documented for phosphatidylcholine among the ingredients we could check.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Major medication interactions have been identified, and safety information is well characterized.

This product is a blend of nutrients with evidence supporting magnesium for digestive issues and constipation, and inositol for PCOS and metabolic syndrome. However, it's not a fit if you take Parkinson's medications, blood pressure drugs, diabetes medications, or certain antibiotics without checking first.

If you take any prescription, run it through our medication checker before starting — potassium and magnesium can both cause serious problems with common heart and blood pressure drugs.

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.

Magnesium15 drug types · 295 drugs

Levodopa/Carbidopa (Sinemet)

Magnesium can reduce the bioavailability of levodopa/carbidopa.
Clinical research in healthy volunteers shows that taking magnesium oxide 1000 mg with levodopa 100 mg/carbidopa 10 mg reduces the area under the curve (AUC) of levodopa by 35% and of carbidopa by 81%. In vitro and animal research shows that magnesium produces an alkaline environment in the digestive tract, which might lead to degradation and reduced bioavailability of levodopa/carbidopa.

Likelihood Probable Evidence B
Aminoglycoside Antibiotics

Concomitant use of aminoglycoside antibiotics and magnesium can increase the risk for neuromuscular weakness.
Both aminoglycosides and magnesium reduce presynaptic acetylcholine release, which can lead to neuromuscular blockade and possible paralysis. This is most likely to occur with high doses of magnesium given intravenously.

Likelihood Possible Evidence D
Antacids

Use of acid reducers may reduce the laxative effect of magnesium oxide.
A retrospective analysis shows that, in the presence of H2 receptor antagonists (H2RAs) or proton pump inhibitors (PPIs), a higher dose of magnesium oxide is needed for a laxative effect. This may also occur with antacids. Under acidic conditions, magnesium oxide is converted to magnesium chloride and then to magnesium bicarbonate, which has an osmotic laxative effect. By reducing acidity, antacids may reduce the conversion of magnesium oxide to the active bicarbonate salt.

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

Magnesium might decrease levels of bictegravir/emtricitabine/tenofovir alafenamide by reducing its absorption.
Advise patients that bictegravir/emtricitabine/tenofovir alafenamide should be taken at least 2 hours before or 6 hours after magnesium containing products.

Likelihood Probable Evidence D
Bisphosphonates

Magnesium can decrease absorption of bisphosphonates.
Cations, including magnesium, can decrease bisphosphonate absorption. Advise patients to separate doses of magnesium and these drugs by at least 2 hours.

Likelihood Probable Evidence B
Calcium Channel Blockers

Magnesium can have additive effects with calcium channel blockers, although evidence is conflicting.
Magnesium inhibits calcium entry into smooth muscle cells and may therefore have additive effects with calcium channel blockers. Severe hypotension and neuromuscular blockades may occur when nifedipine is used with intravenous magnesium, although some contradictory evidence suggests that concurrent use of magnesium with nifedipine does not increase the risk of neuromuscular weakness. High doses of magnesium could theoretically have additive effects with other calcium channel blockers.

Likelihood Possible Evidence D
Digoxin

Magnesium salts may reduce absorption of digoxin.
Clinical evidence suggests that treatment with oral magnesium hydroxide or magnesium trisilicate reduces absorption of digoxin from the intestines. This may reduce the blood levels of digoxin and decrease its therapeutic effects.

Likelihood Possible Evidence B
Potassium-Sparing Diuretics

Potassium-sparing diuretics decrease excretion of magnesium, possibly increasing magnesium levels.
Potassium-sparing diuretics also have magnesium-sparing properties, which can counteract the magnesium losses associated with loop and thiazide diuretics. Theoretically, increased magnesium levels could result from concomitant use of potassium-sparing diuretics and magnesium supplements.

Likelihood Probable Evidence D
Quinolone Antibiotics

Magnesium decreases absorption of quinolones.
Magnesium can form insoluble complexes with quinolones and decrease their absorption. Advise patients to take these drugs at least 2 hours before, or 4 to 6 hours after, magnesium supplements.

Likelihood Probable Evidence D
Skeletal Muscle Relaxants

Parenteral magnesium alters the pharmacokinetics of skeletal muscle relaxants, increasing their effects and accelerating the onset of effect.
Parenteral magnesium shortens the time to onset of skeletal muscle relaxants by about 1 minute and prolongs the duration of action by about 2 minutes. Magnesium potentiates the effects of skeletal muscle relaxants by decreasing calcium-mediated release of acetylcholine from presynaptic nerve terminals, reducing postsynaptic sensitivity to acetylcholine, and having a direct effect on the membrane potential of myocytes. Magnesium also has vasodilatory actions and increases cardiac output, allowing a greater amount of muscle relaxant to reach the motor end plate. A clinical study found that low-dose rocuronium (0.45 mg/kg), when given after administration of magnesium 30 mg/kg over 10 minutes, has an accelerated onset of effect, which matches the onset of effect seen with a full-dose rocuronium regimen (0.6 mg/kg). In another clinical study, onset times for rocuronium doses of 0.3, 0.6, and 1.2 mg/kg were 86, 76, and 50 seconds, respectively, when given alone, but were reduced to 66, 44, and 38 seconds, respectively, when the doses were given after a 15-minute infusion of magnesium sulfate 60 mg/kg. Giving intraoperative intravenous magnesium sulfate, 50 mg/kg loading dose followed by 15 mg/kg/hour, reduces the onset time of rocuronium, enhances its clinical effects, reduces the dose of intraoperative opiates, and prolongs the spontaneous recovery time. It does not affect the activity of subsequently administered neostigmine.

Likelihood Probable Evidence A
Sulfonylureas

Magnesium increases the systemic absorption of sulfonylureas, increasing their effects and side effects.
Clinical research shows that administration of magnesium hydroxide with glyburide increases glyburide absorption, increases maximal insulin response by 35-fold, and increases the risk of hypoglycemia, when compared with glyburide alone. A similar interaction occurs between magnesium hydroxide and glipizide. The mechanism of this effect appears to be related to the elevation of gastrointestinal pH by magnesium-based antacids, increasing solubility and enhancing absorption of sulfonylureas.

Likelihood Probable Evidence B
Tetracycline Antibiotics

Magnesium decreases absorption of tetracyclines.
Magnesium can form insoluble complexes with tetracyclines in the gut and decrease their absorption and antibacterial activity. Advise patients to take these drugs 1 hour before or 2 hours after magnesium supplements.

Likelihood Probable Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, magnesium may have antiplatelet effects, but the evidence is conflicting.
In vitro evidence shows that magnesium sulfate inhibits platelet aggregation, even at low concentrations. Some preliminary clinical evidence shows that infusion of magnesium sulfate increases bleeding time by 48% and reduces platelet activity. However, other clinical research shows that magnesium does not affect platelet aggregation, although inhibition of platelet-dependent thrombosis can occur.

Likelihood Unlikely Evidence B
Gabapentin (Neurontin)

Gabapentin absorption can be decreased by magnesium.
Clinical research shows that giving magnesium oxide orally along with gabapentin decreases the maximum plasma concentration of gabapentin by 33%, time to maximum concentration by 36%, and area under the curve by 43%. Advise patients to take gabapentin at least 2 hours before, or 4 to 6 hours after, magnesium supplements.

Likelihood Unlikely Evidence B
Sevelamer (Renagel, Renvela)

Sevelamer may increase serum magnesium levels.
In patients on hemodialysis, sevelamer use was associated with a 0.28 mg/dL increase in serum magnesium. The mechanism of this interaction remains unclear.

Likelihood Possible Evidence B
Magnesium 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.

Lecithin Granules by Bluebonnet: Common Questions

Does Lecithin Granules by Bluebonnet interact with any medications?
Yes. Based on its ingredients, Lecithin Granules has a known interaction with 422 medications, including 6 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.
What exactly is in this product?
It's lecithin granules — a blend of potassium, magnesium, choline, phosphatidylcholine, and inositol phosphatide, plus monounsaturated and polyunsaturated fats from soy lecithin. These support cell structure and function. There are no inactive fillers.
Does this product actually work for anything?
Magnesium is effective for indigestion and constipation. Phosphatidylcholine shows possibly effective evidence for ulcerative colitis. Inositol is possibly effective for PCOS, metabolic syndrome, and preterm labor. The other ingredients don't have strong established uses in our data.
What are the most common side effects?
Magnesium and choline can both cause diarrhea and nausea at higher doses. Phosphatidylcholine may cause bloating and altered taste. Inositol typically causes mild digestive effects like gas. Most people tolerate these ingredients well at recommended amounts.
Is it safe to take while I'm pregnant or breastfeeding?
Potassium from food is fine, but supplements need medical supervision. Magnesium and choline are likely safe in pregnancy if guided by your doctor. Phosphatidylcholine and inositol safety beyond food is not well established — talk to your obstetrician or midwife before starting any of these.
Can I take this if I have kidney disease?
Potassium supplements can be risky with kidney disease because your kidneys may not clear it properly. Talk to your nephrologist or doctor before taking this product.
What's the difference between getting these nutrients from food and from a supplement?
Food amounts of potassium, magnesium, and choline are generally safe. Supplements deliver higher doses, which can cause side effects and interact with medications — that's why supplements require more caution and medical guidance.
