Overview

Doctor's Best sells this MSM as a loose powder, and the OptiMSM source supplies the sulfur. It is unflavored, and the listing ties it to hair, skin, nails, joint health and mobility.

Powder gives the freedom to set your own dose and avoid swallowing large capsules. The limitation is the missing scoop and serving information, and plain MSM powder has a mild taste that some find bitter.

Who it's for

Adults who dislike swallowing many capsules, and who are happy to measure powder, will get on well with this tub. A person who wants a fixed dose in a single swallow should consider the capsule version instead.

Pros and cons

Pros
  • Dose is adjustable
  • Vegan and soy free
  • No capsule shell
Cons
  • Scoop size not stated

Performance notes

MSM dissolves in water, so the powder can go into any cool drink without clumping much. Dose depends on how much you measure, so a consistent scoop matters. The label gives the serving.
