If you're pregnant or planning to be, this prenatal nails several of the nutrients that matter most. **Folate** is dosed at 800mcg (as folic acid), right at the top of the recommended range for neural tube defect prevention. **Iron** at 27mg uses bisglycinate chelate — a well-absorbed form that's gentle on your stomach. **Calcium** at 1,300mg and **Magnesium** at 450mg are notably generous, covering your full daily needs for both.

**Iodine** (150mcg) meets the baseline for your thyroid during pregnancy, and **Zinc** (15mg) sits at the lower end of the clinical range. The B vitamins are present at roughly RDA levels — enough to prevent deficiency but below the higher therapeutic doses used in clinical research.

The biggest gap is **Vitamin D** at just 400 IU, delivered as D2 — a form your body uses less efficiently than D3. Current research supports 1,000–4,000 IU of D3 during pregnancy, making this four to ten times below the clinical target. **Choline** at 10mg is also essentially absent, despite growing evidence that 450mg+ supports fetal brain development. You'd likely want to supplement both separately.
