HelloPharmacist Scorecard of Choline 350 mg by Solgar

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: choline, a nutrient that plays a role in cell structure, brain function, and muscle control. Each capsule delivers 350 mg of choline.

The capsule itself is made from vegetable cellulose, with vegetable magnesium stearate and silica added as inactive ingredients to help form and stabilize the tablet.

Does it work?

Not established
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 — see Choline's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: brain function and cellular health support.
  • We looked for evidence on: Age-related cognitive decline, Alzheimer disease, Cognitive function, Dementia, Infant development, Neural tube birth defects — and 4 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, Nonalcoholic fatty liver disease (NAFLD), Cognitive function, Dementia, and more.

The evidence for choline supplements is mixed and often insufficient. For athletic performance, the data suggests it's possibly ineffective.

For Alzheimer disease, age-related cognitive decline, bronchitis, hay fever, liver problems linked to total nutrition support (TPN-associated hepatic steatosis), there isn't enough reliable evidence in our data to establish whether it works. If you're considering choline for a specific health goal, talk it over with your doctor or pharmacist about what the current science actually supports.

The evidence, ingredient by ingredient 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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Choline is generally well tolerated when taken at food-level doses or as recommended. This 350 mg dose is well below the tolerable upper daily limit of 3.5 grams.

At very high doses — well above what's in this product — choline can cause a fishy body odor, diarrhea, nausea, vomiting, and excessive salivation. Choline is considered likely safe during pregnancy and breastfeeding, though your doctor or pharmacist should guide your specific dose, since needs are higher at those times.

Side effects, ingredient by ingredient Choline

Meds to double-check

Minor interactions only
Known Interaction Concern · database check
Minor only

Only Minor-severity interactions are documented for these ingredients.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Choline.
  • The most serious interaction on file is rated Minor.
  • For scale: 16 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.

If you take atropine, double-check with your doctor or pharmacist before adding this product. The interaction is Minor, but choline might reduce how well atropine works.

No other medication interactions are documented for the ingredients we could check.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Only minor medication interactions are documented, and safety information is well characterized.

This single-ingredient supplement is appropriate for anyone looking to add choline to their diet at a moderate dose. Because choline may theoretically affect atropine, check with your doctor or pharmacist if you take that medication.

Formula

Choline, a member of the B Complex, is a component of cell membranes and provides key support for optimal cellular function. It is involved in the chemistry of the brain, where it is used to synthesize acetylcholine, a critical neurotransmitter required for brain function. It also promotes normal fat metabolism and provides liver support.

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.

Choline 350 mg by Solgar: Common Questions

Does Choline 350 mg by Solgar interact with any medications?
Yes. Based on its ingredients, Choline 350 mg has a known interaction with 16 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Choline 350 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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 350 mg of choline a lot?
No — it's a modest dose. The tolerable upper limit for choline is 3.5 grams (3,500 mg) daily, so this 350 mg capsule is about a tenth of that ceiling. It's well within a safe range for most people.
Can I take choline if I'm pregnant?
Choline is rated likely safe in pregnancy, and it's actually important during that time. But talk to your doctor or pharmacist about the right dose for you, since your choline needs are higher while pregnant.
What's the fishy smell about?
High doses of choline — much higher than what's in this product — can cause a fishy body odor as your gut breaks down choline into a compound called trimethylamine. At 350 mg, this is very unlikely.
What is choline for, anyway?
Choline is a nutrient your body uses to build cell membranes, support brain and nerve function, and help muscles work. You get it from foods like eggs and meat, but some people take it as a supplement.
Does choline actually help with memory or brain health?
The evidence for choline supplements in Alzheimer disease or age-related cognitive decline isn't established yet in our data. If brain health is your goal, ask your doctor what the current science supports for your situation.
Can I take this while breastfeeding?
Choline needs are higher while you're breastfeeding, and supplements are considered likely safe — but only under professional guidance. Check with your doctor or pharmacist about the right dose for you.
