A two-capsule daily multi where every B vitamin uses a bioactive form your body can absorb directly — no conversion steps needed. **Vitamin D3** at 2,000 IU sits in the clinical sweet spot for maintaining healthy blood levels, and **Selenium** at 200 mcg in a well-absorbed form hits the top of the studied range for antioxidant and thyroid support.

**Zinc** at 15mg and **Vitamin C** at 250mg both land at the minimum effective dose, giving you a solid baseline. Built-in synergies like D3 + K2 and Selenium + Vitamin E are well-matched, though the **K2** is entirely MK-4, which clears your body in hours rather than the days you'd get from MK-7.

The biggest gap is **Magnesium** — just 20mg out of a 100–400mg clinical range. If magnesium matters to your goals, you'd need a separate supplement.
