Why you need it

Sulphur is the third most abundant mineral in your body — and most people have never given it a second thought. It’s quietly essential for keeping your joints cushioned, your skin firm, your hair strong, and your body’s antioxidant defences running. It’s a key building block of collagen and keratin, and your body needs it to produce glutathione — often called the master antioxidant.

The problem is that MSM — the most bioavailable form of organic sulphur — is naturally present in food in only small amounts, and much of it is destroyed by cooking and processing. So even a healthy diet often falls short.

Doctor’s Best uses OptiMSM®, which is widely regarded as the gold standard in MSM supplementation. What sets it apart is how it’s purified: while most MSM products use crystallisation, OptiMSM® goes through distillation — a more thorough process that removes more impurities and delivers a cleaner, more consistent product every time.

The powder itself is tasteless and odourless, dissolves easily in water or juice, and gives you a meaningful 3,000 mg therapeutic dose in every serving. Simple to add to your routine, and genuinely hard to beat for quality.
