MSM

MSM (methylsulfonylmethane) capsules, tablets and powder, in packs of about 60 to 360 units or 227 g to 454 g. Strengths in the titles run from 500 mg to 3,000 mg, but the figure can refer to one capsule or to the daily serving of several, so compare the milligrams of MSM in the daily serving in the nutrition table. For powders, divide the net weight by the grams in one serving; some products also combine MSM with hyaluronic acid.

Frequently asked questions

What is MSM?

MSM is short for methylsulfonylmethane, an organic sulphur compound that some labels spell methylsulphonylmethane. For capsules and tablets the nutrition table gives the milligrams of MSM per daily serving, and for a powder it gives the serving in grams or scoops.

What is the difference between caps and vcaps?

Both are capsules. 'Vcaps' are vegetable or vegetarian capsules with a plant-based shell, while the shell of plain 'caps' may be gelatine. The ingredient list names the shell material, and the nutrition table gives the amount of MSM separately.

How can I compare the price of MSM capsules with MSM powder?

Divide the price by the grams of MSM in the pack. For capsules, take the milligrams of MSM per capsule from the nutrition table, multiply by the number of capsules and divide by 1,000; for a powder that contains only MSM, the net weight is already the grams of MSM. Check the nutrition table if the product contains other ingredients.
