Our assessment

The evidence shows that calcium is a critical mineral for bone health, but supplementation requires careful consideration of dosage and individual risk factors. MegaFood Methyl B12 is a vitamin B12 supplement, and the data provided does not contain specific information on that product. Calcium data is available for general reference. Our assessment: you should not assume this product is a calcium supplement — it is a B12 supplement. For calcium, the data confirms a role in bone mineralization and neuromuscular relaxation [NIH ODS].
