Methyl B-12 5000 mcg

Jarrow invented the methylcobalamin lozenge category. Sublingual delivery bypasses gut absorption issues (common in 50+ adults). 5000 mcg is a correction dose. Cherry flavor that actually tastes good. B12 supplementation done right.

8.0/10
EXCELLENT

Sublingual methylcobalamin at a meaningful dose. The lozenge format bypasses potential gut absorption issues. Jarrow has been the go-to B12 brand for decades. Cherry flavor actually tastes good.
