Overview
This product delivers MSM as large granular flakes rather than a fine powder or capsule, sold in a 1 pound bag. The maker describes it as 99.9% pure and third party tested for purity, details aimed at buyers who want some outside verification of what is in the bag.
The listing itself flags that the crystals can taste bitter and suggests mixing in lime juice to help with that, which is a useful heads up for anyone new to raw MSM crystals. The formula is labeled vegan, gmo free, and organic.
Because it comes as granules rather than a fine powder, some buyers find it dissolves a little slower in water, though the larger flake size can also make it easier to measure by spoon.

Frequently asked questions
Does this MSM crystal product taste bad?
