Overview
Doctor's Best Vitamin B12 uses methylcobalamin at 1500 mcg per capsule in a 180 count bottle of vegetable capsules. The large count gives roughly six months of use at one capsule a day for buyers who want to stock up on a fully active B12 form.
Methylcobalamin is described here as fully active, meaning it does not require the body to convert it from another form of B12 before use, which is why it is favored over cyanocobalamin in some formulations. The 180 count size is well above the 30 to 60 count bottles common in this category, aimed at buyers planning for months of continuous use rather than a short trial.
- 1500 mcg methylcobalamin per capsule
- 180 veg capsules, months-long supply
- Vegan, gluten free, non-GMO
- Soy free
Who it's for
Buyers who want a vegan, gluten free B12 capsule in a large multi-month supply. Not the pick for anyone who wants a small trial size or a softgel rather than a vegetable capsule.
Pros and cons
- 1500 mcg methylcobalamin, described as fully active
- 180 capsules gives roughly six months at one daily
- Vegan, gluten free, non-GMO
- Larger bottle size is a bigger upfront commitment than smaller counts
- Capsule only, no softgel or liquid option
Performance notes
Methylcobalamin is the coenzyme form of B12 the body uses directly, and the fully active labeling here reinforces that the capsule skips a conversion step required by cheaper forms. At 1500 mcg per capsule the dose sits between the low maintenance amounts in multivitamins and the extra strength 3000 mcg products in this category.
