Vitamart's Take
If you want straightforward MSM, this is it: one ingredient, no fillers, and a 500 g bag that St. Francis rates at about three months of use. The label dose is 1,700 mg three times a day, so powder is a practical and economical way to get that much — no handful of capsules required. Mix it into water, tomato juice or fruit juice, take it with meals, and skip the bedtime dose.
How MSM Powder Compares
Powder vs. capsules
Reaching 1,700 mg per dose with capsules means taking several at a time. Powder lets you take the full dose in one drink.
MSM vs. glucosamine
Glucosamine and MSM are both popular for osteoarthritis but are different compounds. Some people take them together; see our Glucosamine and MSM collection for combined formulas.
MSM Powder vs. Curcumin Plus
St. Francis Curcumin Plus combines Meriva curcumin with MSM and grape seed in a capsule. Pure MSM powder gives you a much larger MSM dose on its own.
