Our assessment focuses on the general safety of high-dose B12 supplements. Data not available for the specific efficacy or side effect profile of this product. For general context, calcium, a different mineral, has a well-documented role in bone health, but its safety profile includes potential risks such as constipation, nausea, and interactions with medications like bisphosphonates and levothyroxine [NIH ODS].

How it works
