Our assessment
The evidence shows that while calcium is essential for bone health, the specific product you asked about — Natural Factors Vitamin B6 100 mg — does not contain calcium. Our assessment is based on the data provided for calcium, not for vitamin B6. For calcium, the data supports its role in bone mineralization and nerve function, but high intakes carry significant risks [NIH ODS].
How it works
Think of calcium as a structural builder for your bones and a signal conductor for your nerves. It supports bone density and mineral deposition, and it helps your muscles relax and nerves signal properly [NIH ODS]. This mechanism is critical for maintaining skeletal strength and normal neuromuscular function throughout your life.
Safety profile
FDA received 592,059 adverse event reports for all supplements combined. For calcium specifically, high 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data not available for the specific product Natural Factors Vitamin B6 100 mg. For calcium, we recommend getting your intake primarily from food sources and only supplementing under medical guidance, as high doses carry serious risks [NIH ODS]. Always check for interactions with your medications before starting a calcium supplement [NIH ODS].
