Overview
NOW's MSM capsules provide 1000mg of methylsulfonylmethane per veg capsule in a 240 count bottle, positioned toward joint health and certified halal, kosher and vegan.
This is a single-ingredient sulfur compound supplement rather than a blended joint formula, so it is meant to stand on its own or be paired with other joint-care products separately. The 240 count size covers a long stretch of daily use at one capsule per dose.
- 1000mg MSM per veg capsule
- 240 capsules per bottle
- Halal, kosher and vegan certified
- Labeled for joint health support
Who it's for
Buyers already using MSM as part of a joint-care routine who want a large supply in one bottle. Not the right pick for anyone wanting a multi-ingredient joint formula with glucosamine or chondroitin included.
Strengths and trade-offs
Drawn from this product's published specifications.
- 1000mg MSM per veg capsule
- 240 capsule supply
- Halal, kosher and vegan certified
- Free of corn, dairy, egg, nut and soy
- Single ingredient, no added joint nutrients
- No reviews included to gauge real-world results
Performance notes
MSM is a sulfur-containing compound commonly used as a standalone joint-support ingredient, and 1000mg per capsule is on the higher end of typical MSM dosing. Because it is the only active ingredient here, results depend on how MSM performs on its own rather than in combination with other joint compounds.
