Pack sizes differ 8.3×, so the shelf price tells you very little
BulkSupplements MSM 3000 mg (240 Capsules) holds 60 servings and Nutricost Pure MSM Powder 500 g holds 500: the same shelf price buys 8.3× more of one than the other, which is why all 13 rows above are priced per day.

Method: the 13 MSM products above, compared on label facts, serving size, servings per container, form, price. Not a dosing recommendation.
How these 13 MSM products were ranked
Not one of these 13 MSM products could be confirmed in the NSF, USP or Informed Sport registries, so verification separates none of them and the ranking falls to cost per day at the labelled serving. Commission does not enter it: the rate is the same whichever MSM you buy. Full methodology.
