Vitamin B12

Methylcobalamin — 1,000 mcg

$14/month (30-day supply)

What it does

Methylcobalamin is the bioactive form of B12 — no conversion needed. Delivered as a sublingual tablet that dissolves under the tongue for direct absorption, bypassing the gut entirely. This is essential for adults 60+ who often have reduced stomach acid (achlorhydria) that impairs oral B12 absorption.

Key benefits

Energy production
Nervous system health
Red blood cell formation
Homocysteine control

The evidence

Up to 30% of adults over 60 have B12 deficiency due to reduced intrinsic factor. Methylcobalamin is retained better than cyanocobalamin. Sublingual delivery bypasses absorption issues.

Important

Generally very safe. Extremely rare allergic reactions. No known upper limit toxicity.
