The two nutrients that matter most in a prenatal — **Iron** and **Folate** — are both nailed here. You're getting 45mg of iron as Ferrochel bisglycinate, a form that absorbs well and is far gentler on your stomach than standard iron. **Folate** is delivered as 1mg of methylfolate (L-5-MTHF), the bioactive form your body can use directly — important since roughly half of women carry gene variants that impair folic acid conversion.

Every B vitamin uses its bioactive form, so there's no conversion bottleneck. **Zinc** at 25mg in chelated bisglycinate and **Iodine** at 150mcg round out the prenatal essentials. The **Vitamin C** included also helps maximize your iron absorption — a useful built-in synergy.

The notable gap is **Choline** at just 110mg — only about 20% of the 450mg recommended during pregnancy. If you're relying on this prenatal alone, you'd want to supplement choline separately or ensure your diet covers the rest through eggs and liver.
