Our assessment
The evidence shows that this product contains 1000 mcg of vitamin B12 in a timed-release formula. However, based on the data provided, the primary ingredient with available health information is calcium, not vitamin B12. For vitamin B12-specific benefits, risks, and interactions, data is not available in the provided materials [FDA data].
How it works
Based on the data for calcium, which is the only ingredient with mechanism information, it supports bone mineralization by helping deposit minerals into bone tissue and supports neuromuscular relaxation by aiding nerve signaling and muscle function [NIH ODS]. For how vitamin B12 specifically works in the body, data is not available from the provided sources.
Safety profile
FDA has received a total of 592,059 adverse event reports across all supplement products [FDA data]. For calcium specifically, 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 side effects specific to vitamin B12, data is not available in the provided materials.
Our recommendation
You should be aware that calcium supplements can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. For the vitamin B12 in this product, specific dosage recommendations and interaction data are not available from the provided sources. Consult your healthcare provider before starting this supplement, especially if you take any prescription medications [FDA data].
