Double Wood Choline L-Bitartrate 500mg Review
Double Wood is the bulk-value option: 180 capsules of 500mg choline bitartrate for around $16. It is the cheapest way to buy choline on this list, and Double Wood labels it plainly as ~205mg elemental choline per cap. It ranks #4 because that elemental dose sits below the RDA per capsule and the form, like all bitartrate, is a nutrient top-up, not a fatty-liver treatment.

Form & bioavailability (liver/methylation fit)30%6/10
Standard choline bitartrate: adequate for methylation and phospholipid synthesis but the least potent common form per mg. No delivery enhancements.
Dose vs RDA/clinical range20%6/10
500mg bitartrate yields only ~205mg elemental choline (~40%), below the 425-550mg RDA per capsule. You will likely take two caps to reach adequacy.
Third-party testing & purity20%7/10
Third-party tested, Non-GMO, gluten-free. Solid for a value brand, though not clinician-line documentation.
Tolerability & safety15%8.5/10
At ~205mg elemental per cap, odor and GI issues are unlikely. Well under the tolerable upper limit even at two caps.
Value15%9/10
Around $16 for 180 caps is the cheapest choline-per-gram on the list. Unbeatable if raw cost is the metric.

Marketing claims vs. reality
Partial
“500mg delivers a full dose of choline”
500mg is bitartrate salt weight; only ~205mg (~40%) is elemental choline, below the RDA per capsule. Two caps are needed to comfortably reach adequate intake.
What our test actually found
01Honest about the 40% math
Double Wood discloses that the 500mg salt yields ~205mg elemental choline, avoiding the common trick of implying 500mg of choline. That transparency is why it holds a respectable #4 despite the sub-RDA per-cap dose.
02Value, not liver therapy
This is the pick for cost-conscious buyers correcting a dietary gap. It carries no special liver claim and none is warranted beyond correcting deficiency (PMID 7768984).
Pros & cons, no sugar-coating
Pros
- Cheapest choline per gram on the list
- Honest ~205mg elemental disclosure
- 180-count bottle lasts a long time
- Third-party tested, gluten-free, Non-GMO
Cons
- Sub-RDA elemental choline per capsule; often needs two caps
- Plain bitartrate with no bioavailability edge
- No liver-specific formulation or evidence
The budget workhorse
If you want the most choline for the least money and you are fine taking two caps, Double Wood is the rational buy. For elemental-label clarity and tested purity step up to Pure Encapsulations; for one-cap RDA coverage, Solaray.
