Overview
NOW Foods MSM delivers 1,500 mg of methylsulfonylmethane per serving in tablet form, sold in a 200 count bottle. It is marketed for supporting healthy cartilage and joint health.
MSM is a sulfur compound often paired with glucosamine and chondroitin in joint formulas, though here it stands alone at a higher single-ingredient dose. NOW Foods is a long-running supplement brand, and this tablet format is gluten free. Anyone weighing this against a combination joint product should note it will not include the cartilage-building ingredients those blends add.
- 1,500 mg MSM per tablet
- 200 tablet count
- Gluten free
- Unflavored
Who it's for
Fits people looking for a single-ingredient MSM supplement rather than a multi-ingredient joint blend, at a 1,500 mg per serving dose. It suits those who already know they want MSM specifically and prefer tablets over capsules or powder.
Strengths and trade-offs
Drawn from this product's published specifications.
- 1,500 mg MSM per serving, clearly dosed
- Gluten-free tablet formulation
- Large 200 count bottle
- Single-ingredient only, no combination joint support
- Tablet form may not suit those who prefer capsules
Performance notes
Each tablet is dosed at 1,500 mg of MSM, and the 200 count bottle sets how many servings the container provides depending on the per-day amount taken, which the label directs. The gluten-free labeling matters for anyone avoiding gluten in supplement fillers specifically.
