HelloPharmacist Scorecard of MSM 1000 mg by Puritan's Pride

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.

From our pharmacy team — supplement deep dive

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • “Methylsulfonylmethane” is listed as a grouped ingredient — the label gives one combined amount (1,000 mg) without saying how much of each component you get.

This supplement contains one active ingredient: methylsulfonylmethane (MSM), a form of sulfur that your body can absorb and use. MSM is a naturally occurring compound found in foods and is converted to sulfur once you take it.

The capsule itself is made from gelatin and magnesium stearate (a flow agent).

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: joint and cartilage support.
  • We looked for evidence on: Joint pain, Osteoarthritis, Cartilage health.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The evidence is mixed. Sulfur (what MSM becomes in your body) is rated possibly effective for scabies and dandruff, meaning there's some evidence it helps but the research isn't airtight.

For acne, hay fever, COPD, and the common cold, we don't have enough reliable evidence to say whether it works or not.

The evidence, ingredient by ingredient Sulfur

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Sulfur taken by mouth is generally well tolerated, but the data on oral forms is limited compared to topical (skin) use. The main risks are diarrhea and, in rare cases, a shift in blood acidity (metabolic acidosis) — though that happened in a case where someone consumed a very large amount over several days and had underlying kidney and blood sugar problems.

For pregnancy and breastfeeding, the data suggests it's possibly safe, but because the evidence is thin, talk with your doctor or pharmacist before using it if you're pregnant or nursing.

Meds to double-check

No known interactions
Known Interaction Concern · database check
No known interactions

No medication interactions are currently documented for the matched ingredients — that isn't a guarantee none exist.

Why this rating?
  • None of the 1 matched ingredient has a documented medication interaction on file.

No interactions are documented in our data for the ingredients we could check. Still, talk with your pharmacist about your full medication list before you start.

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.

If you're interested in MSM for scabies or dandruff, there's some evidence it may help. For other uses, the science isn't there yet.

Because oral sulfur is less well studied than topical forms and can cause diarrhea in some people, check with your doctor or pharmacist first — especially if you have kidney or blood sugar problems or take any medications.

MSM 1000 mg by Puritan's Pride: Common Questions

Does MSM 1000 mg by Puritan's Pride interact with any medications?
We do not currently list a known interaction for the mapped ingredients in MSM 1000 mg. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
MSM 1000 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
What is MSM, and what does it do in my body?
MSM stands for methylsulfonylmethane — it's a form of sulfur that gets absorbed when you swallow it. Once in your body, it's converted to sulfur, which some research suggests may help with skin conditions like scabies and dandruff. The evidence for other uses isn't strong yet.
Can I take this if I'm pregnant or breastfeeding?
The data suggests MSM is possibly safe during pregnancy and breastfeeding, but evidence is limited. Before you take it while pregnant or nursing, talk with your doctor or pharmacist for advice tailored to your situation.
What side effects should I watch for?
The most common side effect reported with oral sulfur is diarrhea. In rare cases — usually involving very large amounts — it can affect your blood acidity. If you notice diarrhea or feel unwell, stop taking it and call your doctor.
Does this work for acne or hay fever?
There isn't enough reliable evidence to say. While sulfur is possibly effective for scabies and dandruff, we simply don't have strong data on whether it helps with acne or hay fever.
Are there any inactive ingredients I should know about?
The capsule contains gelatin and magnesium stearate, which are standard binders and flow agents. If you're allergic to gelatin or have concerns about any inactive ingredient, let your pharmacist know.
