The verdict
Clinical dose, proven form.
For general wellness buyers.

Methylcobalamin at 5000mcg in sublingual form. This is 5x the optimal dose, which is fine since B12 has no established upper limit and excess is safely excreted. Active methylcobalamin form plus sublingual delivery makes this ideal for anyone with absorption issues, older adults, or those on metformin.
