Exchange Select Timed Release Vitamin B12 1000 mcg
Brand: Exchange Select · Form: TABLET [E0155]
Our assessment
The evidence shows that while this product contains vitamin B12 at 1000 mcg, the specific health benefits and safety data you need to understand are based on the ingredient calcium, which is listed on the label. For B12-specific outcomes, data is not available. For calcium, the data supports its role in bone health, but you should be aware of important risks and interactions [NIH ODS].
How it works
Calcium acts as a master regulator for your body: it supports bone mineralization and density, and it helps with neuromuscular relaxation and nerve signaling [NIH ODS]. Think of it as a key building block for your skeleton and a calming signal for your muscles.
Safety profile
FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High levels in your 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
Start by checking your total calcium intake from food and other supplements. Be aware that calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. For the vitamin B12 in this product, specific guidance is not available. Consult your pharmacist or doctor before starting, especially if you take any of the listed medications [NIH ODS].
