All new Maxi Health’s "Vitamin K2 with D3 contains the most active form of Vitamin K, and it’s our first liquid offering of a K product to date. We use VitaMK7 Menaquinone-7. Widely sought after by consumers in the know, it is the best option for bioavailability and greater stability over time. It offers support for blood clotting, calcium regulation, and if that were not enough, it’s an antioxidant too! We only use vitamin D3 (as cholecalciferol) which is the same thing you would get from sitting out in the sun. It’s the most usable form for your body. For many people, adequate time in the sun is no longer an option. With busy indoor schedules, requirements of religious dress, and vulnerability to skin problems; supplementation is fast becoming the method of choice for adequate vitamin D intake worldwide.
