Why It Scores 8.4 — And The Label Line Behind Each Number
Form & Bioavailability
25% of scoreCholine bitartrate is a direct, well-absorbed choline salt that feeds the phosphatidylcholine and betaine (methylation) pathways central to liver fat export. It is the most on-target common form for the liver angle, even if less potent per mg than Alpha-GPC.
- Form
- Capsule (choline bitartrate)
Dose vs Clinical Range
25% of score275mg elemental choline is honestly labeled and covers about half the 425-550mg Adequate Intake in one cap. Reasonable, but you may need two caps to approach RDA from supplements alone.
- Dose
- 275mg elemental choline per capsule
Third-Party Testing & Purity
20% of scorePure Encapsulations is a clinician-facing line with hypoallergenic, third-party-tested formulas and no unnecessary excipients. Purity is its core selling point and it delivers.
- Testing
- Third-party tested, hypoallergenic, Non-GMO, vegan
Tolerability & Safety
15% of scoreBitartrate at this modest dose rarely causes the fishy body odor or GI upset seen at gram-plus doses. Well below the 3.5g/day tolerable upper limit.
Value
15% of scoreAround $26 for 100 caps is mid-premium. You pay for the brand's testing rigor, not the raw choline, which is cheap. Fair for a clinician-line product.

Marketing Claims Vs. Reality
Supports liver health and methylation
Choline is required to export fat from the liver as VLDL phosphatidylcholine, and it donates methyl groups via betaine. Deficiency reversibly causes steatosis (PMID 7768984). But supplementing a replete person is not a demonstrated NAFLD treatment (PMID 22337211).
Hypoallergenic and third-party tested for purity
Pure Encapsulations' clinician line is documented as hypoallergenic and third-party tested; the label states elemental choline rather than raw bitartrate weight, matching the sourcing file.
What Our Test Actually Found
Deficiency, not supplementation, is the proven liver story
The strongest human liver data come from choline-deficient states (parenteral nutrition, controlled depletion), where fatty liver appears and reverses with choline (PMID 7768984). That justifies correcting a gap, not dosing an already-adequate person for NAFLD.
Label honesty is the differentiator
Many bitartrate labels print the 500mg salt weight, hiding that only ~40% is choline. Pure Encapsulations states 275mg elemental choline directly, so you actually know what you are taking.
Full analysis: all pros & cons (7), buy if / skip if
- Elemental choline stated on the label, no salt-weight inflation
- Clinician-line purity: hypoallergenic, third-party tested, minimal excipients
- Bitartrate is the most on-target common form for the liver/methylation pathway
- Gentle at this dose; well under the tolerable upper intake
- Costs more per gram of choline than commodity bitartrate brands
- One cap only covers ~half the RDA; heavy dietary gaps may need two
- Not a treatment for established fatty liver in replete individuals
- Elemental choline stated on the label, no salt-weight inflation
- Clinician-line purity: hypoallergenic, third-party tested, minimal excipients
- Bitartrate is the most on-target common form for the liver/methylation pathway
- Costs more per gram of choline than commodity bitartrate brands
- One cap only covers ~half the RDA; heavy dietary gaps may need two
- Not a treatment for established fatty liver in replete individuals
If your diet is short on eggs, liver and cruciferous vegetables, this is the most trustworthy way to reach adequate intake. It is a purity-and-methylation play, not a fatty-liver drug. One 275mg cap covers roughly half the 425-550mg RDA.
Pure Encapsulations takes the top spot because it does the boring things right: a hypoallergenic, third-party-tested bitartrate with the elemental choline stated plainly on the label. Choline is a genuine essential nutrient and a methyl donor, and frank deficiency causes hepatic steatosis. That is exactly why we ranked a straightforward, verifiable bitartrate first. What it is not is a treatment for established NAFLD in someone who is already replete, and we say so throughout.
The honest #1: purity over hype
We rank it first because it is the most verifiable, best-labeled way to close a choline gap and support methylation. Buy it to reach adequate intake, not to 'cure' a fatty liver. If you specifically want a liver-phospholipid form, see the Thorne pick.
If This Doesn’t Fit — Try These
02Thorne Phosphatidyl Choline
If you specifically want the liver-membrane form and elite testing, this is the on-target pick.
03Solaray 500 mg
The convenience-and-value pick: a big, cheap, tolerable single-cap dose for people who just want to top up choline without swallowing two pills.
Quick Answers
How many capsules do I need to hit the RDA?
The Adequate Intake is 425mg (women) to 550mg (men). One 275mg cap covers about half; two caps plus a normal diet comfortably reach it. Most people also get choline from eggs and meat.
Will this reverse my fatty liver?
No product here should be sold that way. Choline correction reverses steatosis caused by choline deficiency. If you are not deficient, treat NAFLD with weight loss and your doctor's plan; use this to cover a dietary gap.
