Around that, we add a pharmacist’s high-level view of the product as a whole — what’s inside, the evidence for its stated use, how transparent the label is, and what safety data exists — so you can see the full picture in one place.

HelloPharmacist Scorecard of MSM 750 by Klaire Labs
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
MSM 750 has two active ingredients: molybdenum and OptiMSM. Molybdenum is an essential mineral your body uses for enzyme function and metabolism.
The product also contains inactive ingredients (the capsule shell and fillers) to hold it together.
Does it work?
Strong evidence
For molybdenum deficiency — the most established use — the evidence rates it likely effective. For acne, iron deficiency anemia, asthma, osteoporosis, and esophageal cancer, the evidence we have is insufficient to rate it one way or the other.
We have no effectiveness data on file for OptiMSM.
How safe is it?
Well-documented data
Molybdenum is generally well tolerated when used at amounts that don't exceed 2 mg per day. High-dose supplements can cause problems and are rarely necessary — that's why the safety data advises caution with supplements above normal dietary amounts.
One case report documented severe toxicity (psychosis, seizures, encephalopathy) from very high-dose use, though this is rare. We have no safety data on file for OptiMSM.
Meds to double-check
No known interactions
No interactions are documented for the ingredients we could check. We couldn't verify OptiMSM, so mention all your medications to your pharmacist before starting.
The bottom line
Scorecard at a glanceFully disclosed formula with strong clinical evidence behind its ingredients' uses. No medication interactions are currently documented, and safety information is well characterized.
This product may help if you have a molybdenum deficiency, though deficiency is uncommon in people eating a varied diet. If you're considering it for another reason — acne, bone health, asthma — the evidence isn't there yet to say it works.
Talk with your pharmacist about whether you need it and whether the dose is right for you.
