HelloPharmacist Scorecard of Choline Bitartrate by KRK Supplements

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

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 bitartrate, a form of choline — a nutrient your body uses to make acetylcholine, a chemical messenger in your brain and nerves. The capsule itself is made with gelatin, microcrystalline cellulose (a binder), magnesium stearate, and silica.

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 nerve transmission support.
  • We looked for evidence on: Age-related cognitive decline, Alzheimer disease, Cognitive function, Dementia, Infant development, Neural tube birth defects — 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, Neural tube birth defects, and more.

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

For age-related cognitive decline, Alzheimer disease, bronchitis, hay fever, liver fat buildup related to specialized IV nutrition, and other conditions, we don't have enough reliable evidence to rate it — the data just isn't there yet.

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 used in normal food amounts or at appropriate supplement doses. However, high-dose supplements do carry a daily upper limit of 3.5 grams.

Doses above that — especially 9 grams daily or more — have been reported to cause nausea, vomiting, diarrhea, sweating, and a distinctive fishy body odor from how your gut metabolizes the choline. Choline is important during pregnancy and breastfeeding, but you should use it only as your doctor advises, not on your own.

Safety data on this supplement during pregnancy and lactation is rated as likely safe, but that means you need personalized guidance — talk with your doctor or midwife before starting.

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 or related medications, run them through our interaction checker before starting this product — choline may reduce how well they work.

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.

Choline bitartrate is for anyone interested in brain and nerve function support, but the evidence for specific conditions is still uncertain. If you take atropine or anticholinergic medications, check with your pharmacist first.

Pregnant or breastfeeding? Talk to your doctor before using — choline matters in both stages, but dosing should be personalized.

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 Bitartrate by KRK Supplements: Common Questions

Does Choline Bitartrate by KRK Supplements interact with any medications?
Yes. Based on its ingredients, Choline Bitartrate 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 Bitartrate 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.
Will choline bitartrate help my memory or prevent Alzheimer's?
We don't have enough reliable evidence to say whether choline helps with age-related memory loss or Alzheimer disease. The research just isn't complete yet for either condition. Talk to your doctor about what's proven to help with your specific concerns.
Is this safe if I'm pregnant?
The safety data rates choline as likely safe during pregnancy, and choline is actually important at that time. But you should use it only at doses your doctor recommends — not on your own. Talk with your doctor about whether you need a prenatal choline supplement.
What's that fishy smell some people report?
At high doses — especially above 3.5 grams daily — choline can cause a fishy body odor. That happens because your gut bacteria break down excess choline into trimethylamine, which your body can't fully clear. Stick to the recommended dose and you're much less likely to notice it.
Can I take this if I'm breastfeeding?
Your choline needs are actually higher while breastfeeding, so supplementation can make sense — but only under your doctor's or lactation consultant's guidance. Don't start on your own; work with a professional to figure out the right approach for you.
What's in the capsule besides the choline?
The capsule contains gelatin, microcrystalline cellulose (a common binder), magnesium stearate, and silica — all standard inactive ingredients that help hold the product together.
