GNC Folic Acid 400 mcg
Brand: GNC · Form: TABLET [E0155] On Market
Our assessment
Our assessment: The evidence shows that folic acid is a critical nutrient for specific health needs, but the data we have on this exact GNC product is limited. We can confirm that the ingredient, folic acid, is well-studied for its role in preventing neural tube defects during pregnancy and supporting red blood cell formation [NIH ODS]. For this specific product, we must rely on general ingredient data, not product-specific clinical trials.
How it works
Folic acid is a B vitamin that acts as a coenzyme in the body. It is essential for DNA synthesis and cell division, particularly during periods of rapid growth like pregnancy and infancy [NIH ODS]. Think of it as the raw material your body needs to build new, healthy cells and to convert homocysteine into methionine, which supports heart and brain health [NIH ODS].
Safety profile
Data not available for this specific product. The FDA has received a total of 592,059 adverse event reports across all dietary supplements, but this number is not specific to GNC Folic Acid 400 mcg. In general, folic acid is considered safe at recommended doses. High intakes can mask a vitamin B12 deficiency, which is a serious concern for older adults [NIH ODS]. No specific side effects with report counts are available for this product from the provided FDA data.
Our recommendation
Our recommendation: If you are a woman of childbearing age or planning a pregnancy, a 400 mcg folic acid supplement is a standard, evidence-based choice [NIH ODS]. For most other adults, you may get enough from a balanced diet. Before starting, check with your doctor if you have a history of vitamin B12 deficiency or take medications that might interact. Choose a product from a reputable brand that has been third-party tested for quality.
