Our assessment
The evidence shows that The Vitamin Shoppe Buffered C-Complex Powder is primarily a calcium supplement. Our assessment: based on the data provided, this product may help support your bone health, but you should be aware of significant safety considerations and potential medication interactions before taking it.
How it works
Think of calcium as a building block for your bones and a signal regulator for your muscles. It supports bone mineralization and density, and it helps your muscles relax and nerves signal properly [NIH ODS].
Safety profile
Safety data is mixed. Some research suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. 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]. The FDA has received 592,059 total adverse event reports across all supplements, though specific counts for this product are not available [FDA data].
Our recommendation
Start by checking your current calcium intake from food and other supplements. If you take this product, be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data not available on the exact dose per serving in this specific powder, so verify the label before use. Consult your pharmacist or doctor if you take any of these medications [NIH ODS].
