For prenatal health, DNA synthesis, and healthy homocysteine levels, this delivers a strong dose. **Folic Acid** at 800mcg hits the top of the 400–800mcg clinical range — a dose well-supported for prenatal health, DNA synthesis, and homocysteine metabolism. At 1,360mcg DFE (dietary folate equivalents), you're comfortably exceeding the RDA of 400mcg.

The form is synthetic folic acid, which requires your body to convert it through multiple conversion steps before it becomes usable. An estimated 30–40% of people carry MTHFR gene variants that slow this conversion, meaning some users may not fully benefit. The included 25mcg of **Vitamin B12** as cyanocobalamin is a reasonable pairing since B12 and folate work together, but at just 10% of the minimum supplemental dose (250mcg), it's more of a trace addition than a therapeutic amount.

If you know you process folic acid well, the dose here is solid. If you're unsure about your MTHFR status, a methylfolate form would give you more reliable absorption.
