How it works
Based on the data provided, calcium supports bone mineralization and neuromuscular relaxation [NIH ODS]. If this product contained calcium, it would help with muscle relaxation and nerve signaling, but the label indicates it is a B12 supplement. For any supplement, the mechanism depends entirely on its active ingredients. Always verify the specific ingredients on your product's label.
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplements [FDA data]. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer, and can cause side effects such as constipation, nausea, and abnormal heart rhythms [NIH ODS]. For this specific B12 product, data on side effects is not available from the provided sources. The recommended daily allowance for B12 is 2.4 mcg for most adults, and 50 mcg is a common supplemental dose, but we cannot confirm its safety profile from the data provided.
