Our assessment
The evidence shows that this product contains Methyl B-12, a form of vitamin B12, but the specific data provided covers calcium, not vitamin B12. For general bone health, our assessment is that calcium is essential, but the data on this specific supplement is limited. The data on calcium indicates it supports bone mineralization and neuromuscular relaxation [NIH ODS].
How it works
Think of calcium as a structural building block for your bones and a nerve signal regulator. It works by supporting bone density and mineral deposition, and it also helps your muscles relax and nerves signal properly [NIH ODS]. For the Methyl B-12 in this product, specific mechanism data is not available from the provided sources.
Safety profile
For calcium, safety data shows that very high intakes might increase the risk of heart disease and prostate cancer. High blood and urine levels can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. The FDA received a total of 592,059 adverse event reports across all supplements, but specific report counts for this product or its ingredients are not available [FDA data].
Our recommendation
For calcium, you should be aware that it can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. For the Methyl B-12 in this specific product, data is not available to make a recommendation. Consider consulting your healthcare provider about your individual needs for both calcium and vitamin B12, as specific data on this supplement is limited.
