Vitamin D3 2000 IU — Briyosis
Huberman takes 5,000 IU daily; most Indians are deficient despite sun exposure due to skin tone, indoor work, and sunscreen. Even 2,000 IU meaningfully raises serum 25(OH)D in deficient individuals. Pair with K2 (MK-7) to direct calcium to bone rather than arteries. Get bloodwork to calibrate your dose.
