Vitamin B12 on TRT
What the number means, why it moves on a protocol, and what people usually do about it.
What it is
Vitamin B12 is needed to make red cells and to keep nerves working. Low B12 feels like tiredness, brain fog and pins and needles.
The range

- Metformin and acid blockers cut absorption.
What people usually do · not a recommendation
- Methylcobalamin under the tongue, or injections through a doctor.

Questions people ask
B12 is way above range, is that dangerous?
No. It is water-soluble and the excess leaves. Very high B12 without supplements is worth a doctor visit, though.
