Vitamin D3+K2 Synergy Formula
Vitamin D and vitamin K are both fat-soluble vitamins. Vitamin D is commonly referred to as the sunshine vitamin because sunlight is required for the production of vitamin D in the skin. However, while the inactive form of vitamin D is produced in the body during sun exposure, a healthy liver and kidneys are also essential for the conversion of inactive vitamin D into its active form (calcitriol). Biological functions of vitamin D go beyond maintaining healthy bones and can benefit other organs and systems in the body especially the immune, cardiovascular, respiratory and nervous systems. Vitamin K2 encompasses a group of vitamers called menaquinones (MKs). They all share the common structure (menadione) but differ in the length of the side chain which determines their bioavailability and tissue distribution. In the human diet, meat and dairy products are the main source of the short-chain menaquinones such as MK-4, while the longer-chain menaquinones, especially MK-7, are predominant
