Why does GCM COMPLEX have such large tablets?
The potency of our formulation means that less daily tablets are required.

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.

What is Opti MSM?
Our GCM COMPLEX features one of the most clinically studied MSM ingredients on the market – OptiMSM®.

OptiMSM® is made up of 34% sulfur – the fourth most abundant mineral in our body – which is used for the maintenance of healthy joints, tendons, ligaments and other connective tissue.

OptiMSM® has been clinically trialled for efficacy, effectiveness in addressing joint pain and is renowned for its purity.

Can I take this product if I have allergies to shellfish?
GCM COMPLEX contains glucosamine sulfate and therefore should not be consumed by anyone with allergies to shellfish.
