Doctor's Best Best Fully Active Folate
Brand: Doctor's Best · Form: CAPSULE [E0159]
Our assessment
The evidence shows that Doctor's Best Best Fully Active Folate contains Calcium as its active ingredient. Our assessment: For most adults, calcium is essential for bone health, but the specific benefits of this product depend on your individual dietary intake. The data confirms calcium supports bone density and muscle relaxation [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton. It supports bone mineralization and density, and it also plays a critical role in neuromuscular relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. 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].
Our recommendation
Start by evaluating your total daily calcium intake from food and other supplements. Calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. We recommend you consult with your healthcare provider before starting this supplement, as safe dosing is highly individual.
