GNC Folic Acid 1000 mcg
Brand: GNC · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that this product contains 1000 mcg of folic acid, but the data provided does not include specific findings for folic acid itself. Our analysis must rely on the calcium data available, which is the only ingredient with detailed information. For calcium, the data indicates that while it supports bone health, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Without specific data on folic acid, we cannot assess its benefits or risks here.
How it works
Based on the calcium data, think of calcium as a structural builder — it supports bone mineralization and mineral deposition, and it helps with neuromuscular relaxation and nerve signaling [NIH ODS]. For folic acid, data is not available on its mechanism from the provided sources.
Safety profile
For calcium, 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]. Calcium can also reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. The FDA has received a total of 592,059 adverse event reports across all products, but report counts specific to folic acid or calcium are not available [FDA data].
Our recommendation
Without specific data on folic acid from the provided sources, we cannot make a confident recommendation for this product. For calcium, data shows that high intakes carry risks, so you should not exceed recommended levels without medical supervision [NIH ODS]. If you are considering this supplement, consult your healthcare provider to discuss your individual needs and potential medication interactions.
