Jarrow Formulas Methyl B-12 1000 mcg: a vegan methylcobalamin chewable
Jarrow Formulas Methyl B-12 is a lemon-flavored chewable tablet with 1,000 mcg of vitamin B12 as methylcobalamin. A 100-tablet bottle costs about $12 on Amazon and has a 4.7-star average from around 5,400 reviews.
What you get
Methylcobalamin is one of the active forms of B12. Most cheaper supplements use cyanocobalamin, which your body converts. Jarrow's listing says research suggests methyl B-12 is better retained in the body than cyanocobalamin. That's the manufacturer's framing; for most people with normal absorption, either form works.
According to the listing, the formula is vegan, non-GMO and free of wheat, gluten, soy, dairy, egg, fish, shellfish, peanuts, tree nuts and sesame. You chew the tablet or let it dissolve, which some people prefer to swallowing pills.
About the dose
1,000 mcg is far above the 2.4 mcg adult recommended intake, but that's normal for B12 supplements, since only a small share of a large oral dose is absorbed. The NIH Office of Dietary Supplements hasn't set an upper limit for B12, because no harm has been reported from high intakes.
Supplements aren't FDA-approved before sale. Jarrow's listing doesn't mention a USP or NSF mark, so if independent certification matters to you, that's worth knowing.
Who it's for
- Vegans and vegetarians, who get almost no B12 from food and should supplement
- People who dislike swallowing tablets
- Anyone who specifically wants the methylcobalamin form
Who should skip it
If you have tingling, numbness or balance problems along with tiredness, see a doctor before self-treating. Severe B12 deficiency, including pernicious anemia, may need injections or a doctor-directed plan. And if you're tired but eat meat and dairy, have no absorption issues and aren't on metformin or acid reducers, B12 may not be your problem.

Alternatives
Nature Made Vitamin B12 1000 mcg is cheaper per day (160 tablets for about $11) and uses cyanocobalamin in a time-release tablet. If you also want vitamin D, see the Nature Made Vitamin D3 2000 IU.
