Our assessment
The evidence shows that this product contains calcium, a mineral essential for bone health. However, based on the data provided, we cannot confirm that Rexall Naturalist B12 1000 mcg actually contains any B12, as that ingredient is not listed in the data. Our assessment is that you should verify the label to see if this product meets your specific needs, as the data only describes a calcium supplement, not a B12 supplement.
How it works
If the product contains calcium, it works by supporting bone mineralization—helping deposit minerals into your bone structure for density—and by supporting neuromuscular relaxation, which aids in muscle and nerve signaling [NIH ODS].
Safety profile
Data not available for adverse events specific to this product. The total FDA adverse event reports for all supplements is 592059 [FDA data]. Potential side effects from calcium include constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, and abnormal heart rhythms [NIH ODS]. High calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
Our recommendation
We recommend you read the product label carefully to confirm the actual ingredients. If it is a calcium supplement, take it with food and separate from medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin to avoid absorption issues [NIH ODS]. Because of potential risks, do not exceed the recommended dose without consulting your healthcare provider.
