Our assessment
The evidence shows that Doctor's Best Fully Active Folate 800 with Quatrefolic provides 800 mcg of folate, a form of vitamin B9. This is a well-chosen dose for supporting key bodily functions, but it is important to understand how it fits into your overall nutrient picture. Data not available on specific benefits for this product from the provided sources.
How it works
Folate, as a B vitamin, acts as a coenzyme in the body, meaning it helps enzymes perform critical reactions. It is essential for DNA synthesis and repair, and for the production of red blood cells [NIH ODS]. The "Quatrefolic" form is a methylated version of folate, which is the active form your body can use directly, bypassing a conversion step some people have trouble with.
Safety profile
FDA has received a total of 592,059 adverse event reports across all dietary supplements. Data not available on specific side effects for this product. However, because this product contains folate, high intakes can mask a vitamin B12 deficiency, which is a serious concern [NIH ODS]. Always consult your doctor before starting any supplement.
Our recommendation
Start by discussing this supplement with your healthcare provider, especially if you take other medications. While 800 mcg of folate is a reasonable dose, ensuring you have adequate vitamin B12 levels is critical [NIH ODS]. This product may be a good option if you need a bioactive form of folate, but rely on your doctor's guidance for your specific needs.
