Overview
7 Lights sells this as a 99.9 percent pure MSM (methylsulfonylmethane) powder in a 1 lb container, vegan, non-GMO, gluten free and made in the USA. It comes as loose powder rather than capsules.
The 99.9 percent purity figure and the Opti-MSM naming both point to the grade of the raw ingredient itself, not a finished capsule blend, which is why this ships as powder rather than pills. Powder means buyers scoop or weigh their own serving instead of taking a preset capsule dose.

Performance notes
Methylsulfonylmethane is a sulfur-containing compound marketed for joint, skin and immune support, and here it is sold as loose crystals rather than a capsule blend. Because it's a powder, the actual serving size depends on how much the buyer scoops or weighs out, since no scoop size is included in the listing data.
