A good supplement for the prevention and treatment of joints. MSM is ideal for those needing extra nutritional support for cartilage and joints. This supplement reduces inflammation and nourishes joints and cartilage, providing sufficient fluid and helping to increase flexibility and mobility, restoring comfort of movement.

Fibromyalgia relief
4 people found this helpful
Works for fibromyalgia! Taking MSM at 1000mg per 30 lbs of body weight alleviates the "body flu" aches effectively. I initially stopped taking it, thinking I felt better, but the body aches returned both times. After resuming, I've seen consistent relief, confirming its effectiveness for fibromyalgia!

Keto flu support

Helps with Keto. When doing the keto diet, I heard MSM aids with keto flu and hair loss. After two bottles, I can confidently say it works for me. My feet don’t crack and pop in the morning. I’m thoroughly convinced!

Supports recovery from flu
I was sick with the flu and became so weak that I fell and injured my tailbone, along with the rest of my body from the jarring. The doctor advised me to take 3000 mg of MSM every hour. It helped my tailbone such that I could sit without leaning sideways. I still take 3000 mg twice a day.

No effect on flu

I bought this to strengthen immunity, believing that sulphur forms the protective layer of our cells. Consequently, a stronger shell would reduce the chance of viruses, including influenza, entering our cells. However, after taking it, I did not notice any effects at all. Plus, kinesiology testing showed that this supplement is a magnesium antagonist.
