What exactly is MSM powder?
Methylsulfonylmethane in a direct loose-powder format.
MSM is the widely recognised abbreviation for methylsulfonylmethane. It is a sulphur-containing compound supplied here as a fine, loose powder with a stated purity of 99%.
British customers may search for MSM powder, methylsulfonylmethane powder, sulphur powder or sulfur powder. These terms describe the same central product identity: Pure MSM Methylsulfonylmethane Sulphur Powder.
The finished product is supplied directly as powder. There is no capsule shell, tablet base or compressed format taking attention away from the MSM itself.
The recognised abbreviation
MSM is the shorter name commonly used on product searches, ingredient lists and supplement labels.
It gives customers a concise way to identify the compound without replacing its complete chemical name.
The complete ingredient name
Methylsulfonylmethane is the full name behind the familiar MSM abbreviation.
Crown Supplements keeps both names prominent so the ingredient is easy to identify before purchase.
Sulphur powder
Sulphur is the familiar British spelling used when describing MSM as a sulphur-containing compound.
Sulfur powder
Sulfur is the alternative spelling customers may encounter when searching for the same MSM ingredient category.
Understanding the product numbers

The headline numbers describe two separate parts of the product. The 99% figure identifies the stated MSM purity, while the gram and kilogram figures identify the four available pouch quantities.

Why choose this MSM methylsulfonylmethane powder?
The MSM should lead the pouch.

Loose-powder format

The Crown Supplements formula standard
Built around MSM—not production convenience.
When a loose powder is stretched with fillers, binders, bulking materials, anti-caking agents or machine flow agents, part of the pouch is being used for production extras instead of the named ingredient customers came to buy.
They may help the machine. They are not the reason the customer buys the powder.
Available powder quantities
Choose the MSM pouch that suits you.
Customers across Great Britain can choose from four MSM methylsulfonylmethane powder quantities. Every pouch contains the same stated 99% formula.
