Short description
CSK Biotech Vitamin D3 + K2 Oral Liquid combines highly bioavailable cholecalciferol (D3) with long‑acting menaquinone‑7 (K2 MK‑7) in an easy‑to‑use liquid form. Designed for superior absorption and convenient daily dosing, this formula supports bone and cardiovascular wellness, and is ideal for adults with limited sun exposure or those seeking an efficient, palatable supplement option.
Key benefits
