Our assessment
The evidence shows that this supplement provides 500 mcg of vitamin B12, which is well above the standard daily requirement for most adults. However, the data provided does not include specific information on vitamin B12, only on calcium. For vitamin B12, data is not available from the provided sources regarding its mechanism, safety, or interactions. Your decision to take this supplement should be guided by a known deficiency or a specific medical need, as high-dose B12 is generally considered safe but its benefits for the general population are not supported by the data here.
How it works
Based strictly on the provided data, the ingredient listed is calcium, not B12. Calcium works as a master regulator for bone mineralization, supporting bone density and mineral deposition, and it also supports neuromuscular relaxation and nerve signaling [NIH ODS]. For the B12 component, specific mechanism information is not available in the provided data.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements, but specific report counts for this product are not available. For calcium, the provided data notes that high intakes might increase the risk of heart disease and prostate cancer. High levels of calcium in the blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. For B12, specific side effects are not available in the provided data.
Our recommendation
We recommend that you consult with your healthcare provider before starting this supplement, especially given the high dose of 500 mcg. The data provided does not confirm the identity or purity of the B12 ingredient, and safety information for B12 is not available. If you have a diagnosed B12 deficiency, a healthcare professional can guide you on the appropriate form and dosage. For general wellness, data is not available to support routine use of this high-dose supplement.
