What Is MSM (Methylsulfonylmethane)?
MSM stands for Methylsulfonylmethane, a naturally occurring organic sulfur compound found in plants, fruits, vegetables, and the human body.
Sulfur plays a vital role in:
- collagen and keratin production
- joint cartilage structure
- detoxification and antioxidant defense
- immune balance
Because natural sulfur levels decrease with age, MSM supplementation is widely used for joint support, skin enhancement, and inflammation reduction.
Top MSM Benefits Backed by Scientific Research
1. MSM Reduces Joint Pain and Inflammation
MSM is best known for its effectiveness in reducing joint pain, stiffness, and swelling, especially in individuals with osteoarthritis.
Scientific Evidence:
A 12-week randomized clinical trial showed that MSM significantly improved:
- pain scores
- mobility
- joint function
📚 Study: Kim LS et al., 2006 – https://pubmed.ncbi.nlm.nih.gov/16309928/
2. MSM Improves Skin Elasticity and Hydration
MSM contributes sulfur to collagen and keratin, which support skin firmness and smoothness.
Clinical studies show MSM can:
- improve skin moisture
- increase elasticity
- reduce redness and irritation
- decrease visible signs of aging
📚 Study: Muizzuddin N et al., 2015 – https://pubmed.ncbi.nlm.nih.gov/32083522/
3. MSM Supports Muscle Recovery and Reduces Fatigue
Athletes commonly use MSM for muscle recovery because it:
- reduces muscle soreness
- lowers oxidative stress
- supports energy metabolism

4. MSM Strengthens Hair and Nails
Sulfur is essential for keratin, the structural protein in hair and nails.
MSM supplementation may:
- reduce nail brittleness
- improve hair shine
- support hair strength and growth
5. MSM Helps With Allergies and Immune Function
MSM reduces seasonal allergy symptoms by lowering histamine release, making it helpful for:
