Overview
An MSM capsule supplement using OptiMSM, a branded sulfur source, packed 180 capsules to a bottle. It targets hair, skin, nail and bone health and is gluten free and non-GMO. At one capsule a day, 180 count runs about six months.
This is the capsule counterpart to a granule MSM product using a different sulfur source, and the OptiMSM branding is the notable difference here: it is a specific manufacturing process rather than a generic sulfur ingredient. The 180 count bottle is a larger supply than most single-ingredient supplements, which suits people who have already settled on daily MSM use rather than those trying it for the first time.
- 180 capsules per bottle
- OptiMSM branded sulfur source
- Gluten free, non-GMO
- Model DRB-00331
Who it's for
Suits people already committed to a daily MSM capsule routine who want a larger 180 count bottle to avoid frequent reordering. Less suited to first-time buyers wanting to try a smaller quantity first.
Pros and cons
- 180 count, about six months at one a day
- Uses branded OptiMSM sulfur source
- Gluten free and non-GMO
- No per-capsule milligram dose listed
- Large quantity may be more commitment than a first-time buyer wants
Performance notes
OptiMSM is a specific branded sulfur source used in the capsules rather than a generic ingredient, which is the label's main differentiator. The listing does not give a per-capsule milligram dose, so exact strength should be confirmed on the bottle.
