Overview
A 1-pound tub of unflavored MSM (methylsulfonylmethane) powder listed at 99.9% purity, positioned as a detox-support supplement meant to be mixed into food or drink rather than taken as capsules.
MSM is a sulfur compound sold in bulk powder here rather than pre-measured capsules, so dosing depends on the buyer weighing or scooping out an amount. The label states a 99.9% purity and lab testing, though the testing method itself isn't detailed in the data provided.
- 1 pound of unflavored MSM powder
- 99.9% purity as stated on the label
- Positioned for detox support
- Powder format for mixing into food or drink
Who it's for
Buyers who prefer mixing a plain powder supplement into smoothies or drinks over swallowing capsules, and who want a large supply without added flavoring. Not ideal for anyone who wants fixed, pre-measured doses.
