This multivitamin covers your general nutritional bases with several ingredients dosed at or above clinical thresholds. You're getting 2,000 IU **Vitamin D3** (cholecalciferol), 200mcg **Selenium** from three different forms, 25mg **Zinc** (citrate and methionine complex), and B vitamins with quality forms — **Folate** as methylfolate (680mcg), **B12** as methylcobalamin (300mcg), and a mix of active and standard forms for **B6** and **Riboflavin**.

Beyond your core vitamins and minerals, the formula includes 470mg **Vitamin C**, 5mg **Lutein** from marigold for eye support, 3mg **Boron**, and 200mcg **Chromium** — all at meaningful doses. **Alpha lipoic acid** (25mg) and **Quercetin** (5mg phytosome) are also present but well below their standalone clinical ranges, so don't count on those for targeted benefits.

**Magnesium** at 100mg as oxide is the weakest link — oxide is the poorest-absorbed form, and 100mg is the bare minimum of the clinical range. If you have specific magnesium needs, you'll want a separate supplement.
