HelloPharmacist Scorecard of M-S-M Sulfur 1,000 mg by Carlson
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This product has 2 active ingredients: sulfur and OptiMSM. Sulfur is a mineral element that's been used topically for skin conditions and has also been taken by mouth as an oral supplement.
The product contains one inactive ingredient, hypromellose, which is a binder that helps hold the capsule together.
Does it work?
Couldn't assess
Sulfur is possibly effective for scabies (a parasitic skin infection) and dandruff. For acne, allergic rhinitis (hay fever), chronic obstructive pulmonary disease (COPD), and the common cold, the evidence is too thin right now to say whether it works — we'd need more reliable studies.
We don't have effectiveness data on file for OptiMSM.
How safe is it?
Well-documented data
Topical sulfur is generally well tolerated, though it can dry out or irritate skin. Oral forms are less studied than the topical kind.
Taking sulfur by mouth has been reported to cause diarrhea and, in rare cases, metabolic acidosis (a shift in your blood pH). One case report involved someone who took a very large amount — about 250 grams over 6 days — and had underlying kidney and blood sugar problems; most people taking a standard dose won't face that risk, but it's worth knowing the possibility exists.
There isn't enough data to know whether this product is safe in pregnancy and lactation — talk with your doctor or pharmacist before using it if you're pregnant or nursing.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredients we could check. We couldn't check OptiMSM, so talk with your pharmacist if you want to confirm it won't affect any medications you're on.
The bottom line
Scorecard at a glanceFully disclosed formula with no assessable stated purpose. No medication interactions are currently documented, and safety information is well characterized.
Sulfur may be worth considering if you're dealing with scabies or dandruff, but the oral form is less well studied than topical sulfur. If you're pregnant, nursing, or have kidney or blood sugar problems, check with your doctor or pharmacist first.
No documented interactions with medications exist for the ingredients we could review, but run your exact drug list through our search tool to be sure.

Formula
Mineral depletion in the soil and mineral loss through food preparation make it difficult for us to get an adequate amount of sulfur. Carlson MSM Sulfur from OptiMSM is a highly bioavailable form of sulfur that's found in many of our body's tissues. It supports joint health by helping to maintain healthy connective tissue and is an important component of skin, hair, and nail proteins.
