vitamin k2 dosage

Vitamin K2 appears in many supplement formats, most commonly liquids, capsules, softgels, and gummies.

Many combined supplements pair 5,000 IU of vitamin D3 with about 100–120 mcg of K2. Other formulations pair lower D3 doses (for example 1,000 IU) with higher K2 amounts (examples include 1,000 mcg) or with smaller MK‑7 doses such as about 45 mcg.

Many formulas include a dietary fat to improve absorption of these fat‑soluble vitamins, for example cold‑pressed olive oil or organic MCT/coconut oil.

Labels typically list a serving size (for example, 1 softgel or 1 gummy), the bottle count (for example, 60 softgels or a 50‑count gummy bottle), and an estimated supply duration (for example, a 120‑capsule bottle described as a 120‑day supply).

Vegan supplements typically use plant‑sourced vitamin D3 from lichen and vegan K2 derived from fermented plant sources (examples include fermented chickpeas or similar plant‑based ingredients).
