Vitamin D3

Vitamin D is often called the “sunshine vitamin.” This is because the body can synthesize it when sunlight exposure is adequate. However, researchers have discovered that vitamin D insufficiency is surprisingly common. This insufficiency affects as much as 70 percent of the population. Vitamin D is a great multi-tasker: It strengthens bone by aiding calcium absorption* It modulates immune function.* It protects prostate cells.* It even boosts brain chemicals needed for positive mood.* Vitamin D3 is better absorbed than vitamin D2.

Vitamin K2 (VitaMK7)

Vitamin K is found in leafy green vegetables, olive oil, and miso. It was first recognized for its role in helping blood coagulate, but it is a key player in bone health as well.* In fact, vitamin K directs calcium from the bloodstream into the bones, regulates several proteins found in bone, and is thought to support bone mineralization.* While synthetic vitamin K1 is widely used in supplements, natural vitamin K2 (as VitaMK7®) is the most easily absorbed form.


Boron (as bororganic glycine) is an essential nutrient for bone health and joint health.* Studies show that people with higher boron concentrations tend to enjoy better joint health than those with low levels.* Six mg per day is the dose found to elicit a good response.


AvoVida® is an all-natural ingredient made from ASU (avocado soy unsaponifiables). The proposed mechanism of action of ASU is through increasing the synthesis of collagen and proteoglycan.* These are two components of connective tissue. ASU also inhibits the release of degradative chemicals.* Human clinical research has shown great results for ASU. It is one of the most effective natural ingredients for cartilage health.*
