How it works

Cartilage is constantly breaking down and being rebuilt as old cells are replaced with new ones. This is a natural process called remodeling.  The key to good joint health is to make sure that as cartilage is being remodeled, it doesn’t break down faster than it’s rebuilt. That’s exactly what Cartilast® does.*

The lead ingredient of Cartilast®, ASU works in two ways. First, it helps your body make more collagen and proteoglycan, two components of connective tissue.* Second, it inhibits chemicals that degrade cartilage.* In other words, ASU helps protect the cartilage you’ve got, and may even build new cartilage to replace what over-exertion, aging, and everyday wear and tear have taken away.*

AvoVida® Avocado-Soy Unsaponfiables (ASU) Extract

Avocado and soybeans both contain unsaponfiable components, which are known to help balance inflammation.* Only a small fraction of the oil in avocado and soy is unsaponfiable, making it impossible to get a therapeutic amount from the diet. ASU concentrates the unsaponfiables in avocado and soy oil. This proprietary ingredient has been proven effective at improving the structure of joints.*

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®)

Higher vitamin K levels have been associated with better joint health.* Vitamin K2 is better absorbed than K1, and menaquinone-7 (MK-7) is a superior form of K2. One study found that MK-7 achieved 7-8x higher blood levels of vitamin K than K1.

Scientists have discovered that people who live in areas with higher boron levels in the soil tend to enjoy better joint health.* Unfortunately, this mineral can be difficult to absorb. Bororganic glycine bonds boron with the well-absorbed amino acid glycine, giving it a free ride into the cells and increasing its absorption and bioavailability.

Packaged in the USA
