Doctor's Best Fully Active Folate 400 mcg
Brand: Doctor's Best · Form: CAPSULE [E0159]
Our assessment
Our assessment: The evidence shows that Doctor's Best Fully Active Folate 400 mcg provides a specific form of folate, but the data available focuses on the mineral calcium, not folate itself. For calcium, the data supports its role in bone mineralization and neuromuscular relaxation [NIH ODS]. You should know that the safety and efficacy of this specific folate product are not directly covered by the data provided.
How it works
Think of calcium as a structural building block for your bones and a key signal for your nerves and muscles. It supports bone density through mineralization and helps your muscles relax properly after contracting [NIH ODS]. Without adequate calcium, your body may leach it from your bones, weakening them over time.
Safety profile
The FDA has received 592,059 total adverse event reports across all supplements [FDA data]. For calcium specifically, the data warns that high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. High blood and urine levels of calcium can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Additionally, calcium supplements can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation: Because the data provided does not include studies or side effect reports specific to Doctor's Best Fully Active Folate, we cannot make a specific recommendation for this product. If you are considering this supplement for folate, we advise you to consult your healthcare provider to determine if it meets your needs. For calcium, do not exceed the recommended dietary allowance without medical supervision, and always take calcium supplements separately from the medications listed above [NIH ODS].
