Life Extension Vitamin B12 Methylcobalamin
High-potency B12 for energy, brain health, and nerve support.. You're getting 5,000 mcg of methylcobalamin, which is the bioactive form your body actually uses. Most cheap vitamins use cyanocobalamin, but this version skips the conversion step in your liver. It's an ideal choice for vegans or older adults who often struggle with B12 absorption. The database likely missed the unit conversion here, as 5mg is a powerhouse dose that works for about 90% of people with B12 concerns.
9.5/10
EXCEPTIONALMethylcobalamin at 5mg (5000mcg), which is 5x the optimal 1000mcg dose. Lozenge form provides sublingual absorption. B12 has no upper limit and excess is harmlessly excreted. The high dose ensures adequate levels even in people with absorption issues. Textbook B12 supplementation from a trusted brand.
