Douglas Laboratories Vitamin B12
Brand: Douglas Laboratories · Form: TABLET [E0155]
Our assessment
The evidence shows that calcium is a critical mineral for bone health, but it is not the primary ingredient in this product. The data provided specifically covers calcium, not vitamin B12. Therefore, our assessment is based on the available data for calcium, as no specific vitamin B12 data was provided. For bone health, calcium is essential, but you must be mindful of intake levels and potential risks [NIH ODS].
How it works
Think of calcium as a structural builder for your skeleton. It supports bone density and mineral deposition, making your bones stronger. Additionally, it plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements, though this number is not specific to calcium alone. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. Very high levels 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] [FDA data].
Our recommendation
Because the data for vitamin B12 is not available, we cannot recommend this product for that purpose. For calcium, you should aim to meet your needs through diet first. If you do take a calcium supplement, avoid exceeding the recommended daily intake and be aware of interactions with medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS].
