It helps convert homocysteine to methionine, which is essential for DNA synthesis and nervous system function. The 5000 mcg dose is significantly above the standard RDA, intended for those with impaired absorption or confirmed deficiency. Data not available for mechanism specific to this brand.

Our recommendation
We recommend you start by having your serum B12 and homocysteine levels checked by your doctor. If a deficiency is confirmed, this 5000 mcg methylcobalamin form is a good choice for sublingual use.
