Sundown Naturals B6 100 mg
Brand: Sundown Naturals · Form: TABLET [E0155]
Our assessment
The evidence shows that Sundown Naturals B6 100 mg delivers a high dose of vitamin B6. However, for the ingredient calcium, data indicates that high intakes may increase the risk of heart disease and prostate cancer [NIH ODS]. Based on the available data, we cannot confirm the specific benefits of this product without more targeted studies.
How it works
Calcium supports bone mineralization and neuromuscular relaxation, helping your muscles and nerves function properly [NIH ODS]. Think of it as a structural building block for your skeleton and a regulator for muscle signaling.
Safety profile
FDA received 592059 total adverse event reports across all supplements. For calcium specifically, 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]. Data on side effects for this exact product is not available.
Our recommendation
We recommend you consult your healthcare provider before taking Sundown Naturals B6 100 mg, especially since calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Start with a lower dose if you are new to this supplement.
