Frequently Asked Questions

What are glycosaminoglycans and how do they help performance?

Glycosaminoglycans (or GAGs for short) are simply an umbrella category for a range of familiar compounds including collagen, hyaluronic acid, heparin and chondroitin. They serve a wide variety of biological functions, but most notably, serve as a key foundational player to musculoskeletal health – playing a pivotal role in the protection and maintenance of joints.

What is OptiMSM® and how does it work?

Methylsulfonylmethane (or MSM for short) is a proven bioavailable source of sulfur, important for several functions including the support of connective tissue, immunity, and metabolism. protects the body from oxidative damage by increasing the body’s natural antioxidant capacity so that it can neutralise damaging free radicals. The decrease in inflammation and oxidative stress protects joints, helps the body recover from strenuous activity, boosts immunity, and helps athletes stay mobile.

Why does GCM COMPLEX have such large tablets?

GCM COMPLEX has one of the highest per tablet doses on the market, which means our tablets are larger than most. Our formulations have been developed to provide a clinical dosage of two (2) tablets per day, as opposed to three or four. Our tablets have been designed with a ‘break bar’ to allow a single tablet to be taken in two halves for easy consumption.

How are glucosamine and chondroitin good for athletes?

Glucosamine and chondroitin are components – or building blocks – of normal cartilage. Glucosamine is a substance found naturally in the fluid that surrounds your joints, while chondroitin is found in the cartilage around your joints – both substances play a role in keeping your joints cushioned and lubricated. A combination of these glycosaminoglycans are often supplemented by runners who develop issues in their joints due to the ongoing impact and frequency of training.

When's the best time to take GCM Complex for performance outcomes?

For optimal effect on joint pain and mobility, take two times per day with meals. For athletes, this is best paired with ULTRA OMEGA, to ensure omega-3s can assist in controlling inflammation and enhancing tissue repair.
