Product description
Zellkraft is a high-dose vitamin B12 single-ingredient product with a total of 500 µg B12 from methyl- and adenosylcobalamin. The product character lies in the combination of two active cobalamin forms in a very simple formula. From an orthomolecular perspective, such a high B12 intake should be used according to need; for longer-term use, laboratory markers such as holotranscobalamin, methylmalonic acid or homocysteine may be more informative than dose alone.
