Our assessment
The evidence shows that while the product is labeled as Natural Factors Vitamin B6, the data provided is for a different ingredient: calcium. Data not available for Vitamin B6 specifically. For the ingredient calcium, our assessment is that it plays a clear role in bone health, but high intakes carry significant risks that you need to understand [NIH ODS].
How it works
Think of calcium as a structural builder for your bones and a signal regulator for your nerves and muscles. It supports bone density through mineralization and helps your muscles relax and nerves signal properly after contraction [NIH ODS].
Safety profile
FDA received 592059 adverse event reports across all supplements, though specific numbers for calcium alone are not available. The data shows that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. High levels 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 absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data not available for a specific recommendation on Vitamin B6. For calcium, we advise you to get most of your calcium from food sources and only supplement under medical guidance. Be aware of the serious side effects and drug interactions listed above before starting any calcium supplement [NIH ODS].
