Our take

Each Thorne capsule holds 1 mg of vitamin B12 (1,000 mcg), and the label names the form as methylcobalamin. The Amazon listing says this form is used by the body more efficiently than other B12 forms. The label lists it as the only active ingredient.

The label says the bottle is made in the USA and is gluten free. Not sure which B12 form fits you? Our methylcobalamin versus cyanocobalamin guide lays out the difference.

Pick it if you want a plain methylcobalamin capsule that NSF lists for sport. Prefer a bigger bottle? WeightWorld has 450 tablets of 1,000 mcg in the same form (see below).
