Vitamin B12
Methylcobalamin — typical dose 1,000 mcg
We don’t sell Vitamin B12. Whether you actually need it — and at what dose — depends on your bloodwork. Get your analysis to find out.
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.
