If the whole point is liver, phosphatidylcholine is the form that best matches the biology: it is the actual phospholipid the liver uses to package and export fat, and it supports bile and cholesterol metabolism. Thorne's third-party-certified softgel is the most liver-specific pick on this list. We hold it at #2, not #1, because the elemental choline per softgel is low relative to its price, so it is an expensive way to buy choline gram-for-gram.

▸ THE SCORE

How we built the SAC Product Score™8/10

Form & Bioavailability25%8.5/10

Phosphatidylcholine is the membrane phospholipid the liver uses to export triglycerides as VLDL and to build bile. For the liver angle it is the most mechanistically apt form on the list.

Dose vs Clinical Range25%6.5/10

The labeled serving is one softgel delivering 420mg phosphatidylcholine. That is still below the doses used in the clinical steatosis trials, and phosphatidylcholine converts to relatively little elemental choline by weight. It is a phospholipid delivery vehicle, not a high-choline dose; you take it for the form, not the milligrams.

Third-Party Testing & Purity20%9/10

Thorne's in-house certified testing, gluten-free and dairy-free formulation is among the most rigorous in the category.

Tolerability & Safety15%8.5/10

Phosphatidylcholine softgels are generally well tolerated; mild GI effects at higher intakes. No odor issue typical of high-dose bitartrate.

Value15%7.5/10

Around $34 for 60 softgels is a 60-day supply at the labeled one-softgel serving, about $0.57/day — cheaper than we first had it, since the label prints one softgel per serving, not three. It is still expensive per gram of elemental choline because phosphatidylcholine is a low-choline-density form. You pay for the form and Thorne's testing.

▸ TRUTH CHECK

Marketing claims vs. reality

Partial

Supports liver, bile and cholesterol metabolism

Phosphatidylcholine is the phospholipid used for VLDL export and bile; essential-phospholipid trials show modest steatosis improvement (PMID 32095253). Evidence is supportive but not definitive, and much of it uses higher polyunsaturated-PC doses than one softgel serving.

Verified

Phosphatidylcholine is a more liver-relevant form than bitartrate or Alpha-GPC

Mechanistically the liver exports fat specifically as phosphatidylcholine-coated VLDL; this form is downstream of choline and directly relevant, unlike cognition-oriented Alpha-GPC/citicoline.

▸ THE DEEP DIVE

What our test actually found

01Correction: label shows 420mg phosphatidylcholine per one-softgel serving

An earlier version of this review said the labeled serving was three softgels delivering roughly 385mg phosphatidylcholine total, making a 60-count bottle a 20-day supply at about $1.70/day. The Supplement Facts panel reads 1 gelcap per serving, 420mg Phosphatidylcholine, 60 servings per container. We re-read the label on Sep 7, 2026 and corrected the serving size, per-serving dose, bottle-supply length, cost-per-day math, and the Dose vs Clinical Range and Value scores throughout this review.

02Best-matched biology, modest clinical size

The MANPOWER study of polyunsaturated phosphatidylcholine reported reduced steatosis in NAFLD patients with cardiometabolic comorbidities (PMID 32095253), but the effect was modest and the doses studied exceed a single softgel serving.

03You are buying a form, not a dose

Elemental choline per serving is low. If your goal is simply reaching the choline RDA cheaply, a bitartrate delivers far more choline per dollar. This pick is for people who specifically want the phospholipid.

▸ THE TRADE-OFFS

Pros & cons, no sugar-coating

Pros
  • Most liver-and-bile-specific form on the list
  • Thorne's certified third-party testing is category-leading
  • Real, if modest, human steatosis evidence for the phospholipid class
  • Gentle, no high-dose choline odor issue
Cons
  • Expensive per gram of elemental choline, even though the labeled serving is just one softgel
  • Low elemental-choline yield, poor for simple RDA coverage
  • Clinical steatosis data use higher PC doses than one serving delivers
▸ THE BOTTOM LINE

The connoisseur's liver form

Pick Thorne if you want the phospholipid pathway and you value Thorne's testing over cost efficiency. For plain choline adequacy or methylation, the Pure Encapsulations bitartrate is a better-value #1. Neither cures established NAFLD.
