What is MSM and how may it support skin health?

MSM (methylsulfonylmethane) is an organic sulfur compound found in many foods. Sulfur is a key component of keratin and collagen. Some clinical studies suggest MSM supplementation may improve skin texture, reduce wrinkles and fine lines, and support joint and connective tissue health. It may also have anti-inflammatory effects.

What dosage of MSM has been studied for skin benefits?

Clinical studies have used 1–3 grams of MSM per day for skin-related outcomes. A skin study using 3 grams of MSM daily for 16 weeks showed improvements in wrinkles, skin firmness, and hydration. MSM is often combined with vitamin C or collagen. Doses up to 6 grams daily have been studied for joint health.

What are the potential side effects of MSM supplements?

MSM is generally well tolerated. Mild side effects include nausea, diarrhea, bloating, and headache. Some individuals report insomnia when taking MSM in the evening. MSM may have mild blood-thinning effects. Allergies to sulfonamide antibiotics or sulfites do not predict MSM intolerance, as MSM is a different compound.
