GNC Folic Acid 800 mcg
Brand: GNC · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that folic acid at 800 mcg is a well-established supplement for supporting key bodily functions. However, the specific data provided here is for calcium, not folic acid. Based on the available information, we cannot assess folic acid directly. For calcium, our assessment is that it plays a critical role in bone health and nerve function, but you must be aware of safety limits and medication interactions [NIH ODS].
How it works
Think of calcium as a structural builder for your bones and a signal messenger for your nerves. It supports bone mineralization and density, and it helps your muscles relax and your nerves send signals properly [NIH ODS].
Safety profile
Data not available for folic acid specifically. For calcium, high intakes might increase the risk of heart disease and prostate cancer. 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]. The FDA received a total of 592,059 adverse event reports across all supplements [FDA data].
Our recommendation
Data not available for folic acid. For calcium, you should be cautious with high-dose supplements. Calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Consult your healthcare provider before starting any new supplement, especially if you take prescription medications.
