02 / Ideal for

One organic sulfur.
Many routines.

A versatile sulfur supplement many people add to daily wellness routines. These are common reasons shoppers choose MSM — not medical claims.

Joint & Connective Tissue

One of the most common reasons people supplement with MSM — sulfur is a building block of the connective tissue throughout the body. Studied for joint and connective-tissue support.

Skin, Hair & Nails

Sulfur is a component of collagen and keratin — the structural proteins in skin, hair, and nails. A popular addition to beauty-from-within routines.

Antioxidant Pathways

MSM is studied for its role in supporting the body's natural production of glutathione, an endogenous antioxidant. Many shoppers incorporate it for this reason.

Active Recovery

Popular among active people as part of a post-exercise routine. Research has examined MSM in the context of exercise recovery and oxidative stress.

Seasonal Wellness

Some research has looked at MSM and the body's response to seasonal environmental allergens. A common part of seasonal wellness routines.

Flexible Dosing

Powder lets you dose precisely by body weight and adjust as needed — more practical than capsules for anyone taking 3 g or more per day.

03 / Why this one

Not all MSM
is the same.

The MSM market varies widely in purity and provenance. A few attributes set OptiMSM® apart from generic recrystallized material.

GRAS

GRAS notice with an FDA “no questions” letter.

OptiMSM® has a GRAS (Generally Recognized As Safe) notice, GRN 229, that received an FDA “no questions” letter in 2008, and it is supported by extensive safety research including long-term human clinical studies. To be precise about what this means: the manufacturer self-affirmed GRAS status through expert review and notified the FDA, which responded with a “no questions” letter.

99.9

99.9% pure, by distillation.

OptiMSM® is produced through a proprietary multi-stage distillation process that achieves 99.9% purity — rather than the recrystallization methods that can leave trace impurities in lower-grade MSM. Every batch we receive is third-party tested for identity and purity.

⚗️

~34% elemental sulfur.

MSM is approximately 34% elemental sulfur by weight, making it one of the most concentrated organic sulfur sources available as a dietary supplement. Sulfur is a component of collagen, keratin, and the body's antioxidant pathways.

🌱

Vegan, non-GMO, allergen-free.

OptiMSM® is vegan, non-GMO Project Verified, gluten-free, allergen-free, and non-shellfish-derived. A clean fit for a wide range of dietary needs, with no animal-derived inputs at any stage.

✨

Nothing but MSM.

No fillers, binders, anti-caking agents, or flow agents — just 99.9% pure methylsulfonylmethane powder. The same powder works for oral supplementation and for mixing into a simple topical solution.

Packaged in Madera, California.

Repackaged in our family-operated FDA-registered facility in Madera under strict quality-control protocols — the same facility that handles our full line of fertilizer and wellness products.

04 / The science

What MSM is, and what "GRAS" actually means.

~34% sulfur

Methylsulfonylmethane, (CH₃)₂SO₂

MSM — methylsulfonylmethane — is a naturally occurring organic sulfur compound found in all vertebrates, including humans, and present in small amounts in fresh fruits, vegetables, grains, and animal products. Much of the dietary MSM in food is lost during cooking, processing, and storage, which is why supplementation is commonly used to restore intake.

Despite often being described simply as a "sulfur supplement," MSM does more than donate sulfur. It supports sulfur metabolism and helps the body incorporate sulfur into proteins, connective tissue, and antioxidant pathways. Roughly 34% of its molecular weight is elemental sulfur — a high proportion among supplemental sulfur sources.

On the regulatory side, it is worth being precise. GRAS stands for "Generally Recognized As Safe." The FDA does not "approve" or "designate" GRAS status; rather, a manufacturer self-affirms GRAS through qualified expert review and may notify the FDA, which can respond with a “no questions” letter. OptiMSM®’s notice, GRN 229, received one in 2008.

For a deeper look at the research, see The Complete Guide to MSM Powder: Benefits, Usage, and Safety.

Key Ingredient

One ingredient. That is the entire product.

OptiMSM® Methylsulfonylmethane ((CH₃)₂SO₂)

The only ingredient. 99.9% pure, distillation-produced, vegan, ~34% elemental sulfur by weight. No fillers or flow agents. Manufactured by Bergstrom Nutrition.

Allergen note: OptiMSM® is gluten-free, allergen-free, and non-shellfish-derived. If you are sensitive to sulfa drugs, note that MSM is a structurally distinct organic sulfur compound and no allergic cross-reactivity has been identified in research — but consult your healthcare provider if you are uncertain.

What to Expect

First use: MSM powder has a mildly bitter, slightly sulfurous taste. Most shoppers dissolve it in water or juice with a little honey or maple syrup, or load it into empty capsules. Starting at a lower dose for the first week is the gentlest approach.

Week 1-2: Some new users notice mild, temporary digestive changes when starting — these usually settle as the body adjusts. A gradual ramp over 2-3 weeks tends to be the smoothest.

Week 4-8: MSM is a consistency supplement. Many shoppers report noticing a difference only after 4-8 weeks of steady daily use. Individual experience varies.

05 / How to use

Measure.
Mix.
Split the dose.

Three ways to take MSM powder. Always follow the directions and Supplement Facts on your bag. See the Dosage Guide band for body-weight amounts.

Oral — Dissolved in Water

Quick answer: Dissolve your body-weight dose in 8-12 oz of distilled or filtered water, split into a morning and an afternoon serving.

Measure your dose using the body-weight guide in the Dosage band below.
Dissolve the powder in 8-12 oz of distilled or filtered water. Avoid chlorinated tap water — chlorine may interfere with sulfur uptake.
Add a little honey, maple syrup, or coconut sugar to offset the mild bitterness, if you like.
Split your daily total into two equal servings — one morning, one afternoon or early evening — for steadier intake through the day.
May be taken with or between meals. Some shoppers find it easier on the stomach with food.

Tip: Start low and build gradually — 1-2 g per day for the first week, increasing to your full body-weight dose over 2-3 weeks. A gradual ramp reduces the mild temporary digestive changes some new users notice when starting at a full dose.

06 / Dosage & timing

Dose by body weight.
Split it in two.
Stay consistent.

There is no established RDA for MSM. Research and common practice suggest 1.5-6 g per day for healthy adults. Always follow the Supplement Facts on your bag.

Body-Weight Dosage Reference

Based on the OptiMSM® body-weight approach. Always follow the Supplement Facts on your bag.

Body-weight dosage reference for MSM powder
Body Weight	Daily Dose	Per Serving (÷2)	Approx. Measure
100 lbs (45 kg)	4 g	2 g	½ tsp per serving
125 lbs (57 kg)	5 g	2.5 g	⅝ tsp per serving
150 lbs (68 kg)	6 g	3 g	¾ tsp per serving
175 lbs (79 kg)	7 g	3.5 g	~⅞ tsp per serving
200 lbs (91 kg)	8 g	4 g	1 tsp per serving

01

Split into two servings.

Morning and afternoon/evening. Splitting is associated with steadier sulfur availability and better overall absorption than a single large dose.
02

With or without food.

MSM can be taken on an empty stomach or with meals. Some shoppers find it gentler on the stomach with food.
03

Mind the evening dose.

MSM's role in energy metabolism means some people notice a mild stimulating effect. If that happens, move the second serving to mid-afternoon.
04

Use clean water.

Dissolve in distilled, filtered, or RO water. Chlorine in tap water may interfere with sulfur uptake — the same guidance applies to other mineral supplements.

Measuring & Upper Range

One level teaspoon of MSM powder weighs about 4 g — use a digital kitchen scale for doses between teaspoon marks. Studies examining MSM up to 9 g per day in healthy adults have reported a favorable safety profile. Mild intestinal discomfort, loose stools, or temporary headache are most associated with higher doses or rapid escalation, and usually resolve as the body adjusts. If they persist, reduce the dose and ramp more slowly.

These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.

07 / Compare

Powder
or capsules?

Both deliver the same active compound — methylsulfonylmethane. The difference is convenience, flexibility, and cost.

Dose flexibility	Fully adjustable by body weight	Fixed per capsule (500-1,000 mg)	Body-weight dosing
Cost per gram	Lower — more economical at scale	Higher — includes encapsulation cost	Daily long-term use
Higher doses (4-8 g/day)	Easy — one or two servings	Requires 6-16 capsules	Higher daily amounts
Ease of use	Requires measuring and mixing	No preparation needed	Convenience
Taste	Mildly bitter — maskable	No taste — encapsulated	Taste-sensitive users
Topical use	Mix into lotion or gel directly	Must open and empty capsule	DIY topical
Travel	Bulk bag is less portable	Pre-counted, easy to carry	On-the-go dosing

08 / Decision

Is the powder
the right format for you?

A short fit-check so you can decide quickly.

A Great Fit If You

Want flexible dosing adjustable by body weight
Need higher daily amounts (3 g or more) and want to avoid swallowing many capsules
Are comfortable dissolving powder in water or juice
Want the most economical per-gram cost
Want OptiMSM® specifically, with its FDA “no questions” GRAS letter
Intend to use it both orally and topically

Consider Another Option If

You need pre-measured doses for travel — capsules are more portable
You strongly dislike any bitterness and cannot mask it — capsules avoid the taste entirely
You want a topical magnesium routine instead — see Magnesium Oil Spray or Magnesium Cream
You are pregnant, nursing, or on blood-thinning medication — consult your healthcare provider before choosing any MSM product

Choose your size →

09 / Build the routine

MSM for sulfur.
These complete the routine.

Many shoppers pair MSM with magnesium for a broader mineral-and-sulfur wellness routine.

Oral & Topical

Magnesium Chloride USP

Dead Sea USP magnesium chloride powder — use as an oral magnesium supplement or to make DIY magnesium oil. Pairs well with MSM for mineral-and-sulfur support.

Topical

Magnesium Oil Spray

Ready-to-use Dead Sea magnesium chloride spray. Many shoppers pair oral MSM with topical magnesium for a complementary routine.

Bath Soak

Epsom Salt (Magnesium Sulfate)

USP-grade magnesium sulfate for relaxing bath soaks. A natural pairing with MSM for those focused on muscle comfort and post-activity routines.

Skincare

Magnesium Cream

Ready-to-use topical magnesium cream for targeted application. A convenient complement to a daily MSM routine.

10 / Safety & handling

Read this before
you start.

A short safety summary. Keep out of reach of children. Always follow the Supplement Facts on your bag.

Consult your healthcare provider before use if you are pregnant or breastfeeding (sufficient safety data in these groups is not available), take blood-thinning medication such as warfarin, have kidney disease or impaired kidney function, or take other prescription medications.
Sulfa-drug sensitivity: MSM is a structurally distinct organic sulfur compound, and no allergic cross-reactivity with sulfa drugs has been identified in research. Consult your provider if you are uncertain.
Start low, build gradually. Mild intestinal discomfort, loose stools, or temporary headache are most associated with higher doses or rapid escalation, and usually resolve as the body adjusts. If they persist, reduce the dose.
Handling: avoid inhaling fine powder dust when measuring large amounts. Wash hands after measuring if preparing topical solutions.
Storage: store in a cool, dry place out of direct sunlight and humidity; keep the bag sealed or in an airtight container (MSM may clump if exposed to moisture). No refrigeration needed.
First aid: for eye contact, flush with clean water for 15 minutes and seek medical attention if irritation persists. For excessive ingestion, contact Poison Control (1-800-222-1222); do not induce vomiting. For dust inhalation, move to fresh air.

11 / FAQ

Common questions.
Honest answers.

If your question is not here, contact our team at questions@greenwaybiotech.com.

What is OptiMSM® and why does it matter?

OptiMSM® is a branded form of methylsulfonylmethane manufactured by Bergstrom Nutrition using a proprietary multi-stage distillation process to 99.9% purity. Its GRAS (Generally Recognized As Safe) notice, GRN 229, received an FDA “no questions” letter in 2008, and it is supported by extensive safety research. Not all MSM is made to this standard — recrystallized products may retain trace impurities. Greenway Biotech carries OptiMSM® exclusively.

What does "GRAS" actually mean here?

GRAS stands for Generally Recognized As Safe. The FDA does not "approve" or "designate" GRAS status. A manufacturer self-affirms it through qualified expert review of the safety data and may notify the FDA, which can respond with a “no questions” letter. OptiMSM®’s notice, GRN 229, received one in 2008. It means the ingredient's safety is well supported; it is a safety designation only, and says nothing about any medical condition.

How much MSM should I take per day?

A widely used starting point is about 4 grams per 100 pounds of body weight per day, split into two equal servings. Someone around 150 pounds would typically take about 6 grams daily — 3 grams morning and 3 grams afternoon. Research suggests effective amounts generally fall between 1.5 and 6 grams per day for healthy adults. See the Dosage Guide band above, and consult your healthcare provider for personalized guidance. More detail in The Complete Guide to MSM Powder.

Why take MSM twice a day?

Splitting the daily dose into two servings helps maintain steadier sulfur levels through the day. The digestive system absorbs a finite amount at once, so spacing intake makes more of the MSM usable rather than excreted. Once-daily dosing is common among those who find splitting inconvenient, but twice-daily is generally considered the more effective pattern based on absorption dynamics.

Why distilled or filtered water instead of tap water?

Chlorine in municipal tap water may interfere with sulfur uptake. Using distilled, filtered, or reverse-osmosis water removes chlorine and other potential disruptors. This is a widely cited recommendation among MSM users and is consistent with guidance for other mineral supplements.

What does MSM taste like, and how do I make it easier to take?

MSM powder has a mildly bitter, slightly sulfurous taste that most people find easy to mask. Common approaches: dissolve it in fresh juice, add raw honey, maple syrup, or coconut sugar, or blend it into a smoothie. If you cannot tolerate any bitterness, load the powder into empty size 00 capsules — each holds about 0.5-0.7 grams, so a 3 g serving is roughly 5-6 capsules.

What are the most common reasons people take MSM?

MSM is one of the most widely used dietary sulfur supplements. Common reasons shoppers cite include joint and connective-tissue support, skin and hair support through collagen and keratin, post-exercise comfort, and support for the body's antioxidant pathways via glutathione. These are general reasons for use, not medical claims. Explore 4 Benefits of MSM and How MSM Supports Your Immune System.

Can MSM help with seasonal allergies?

Some research has examined MSM and the body's response to seasonal environmental allergens, possibly through its role in inflammatory pathways. Many people include MSM in a seasonal wellness routine. This is an area of ongoing study, not a treatment claim. Read more: Can MSM Help With Seasonal Allergies?

Is MSM safe to take long-term?

OptiMSM® is the most extensively studied form of MSM and has a favorable safety record in human trials, with studies examining doses up to 9 grams per day without identifying serious adverse effects. As with any supplement, consult your healthcare provider if you have existing health conditions, take prescription medications, or are pregnant or breastfeeding.

Is this product vegan?

Yes. OptiMSM® is vegan, non-GMO Project Verified, gluten-free, allergen-free, and non-shellfish-derived. The powder is the single ingredient with no animal-derived inputs. (If you load it into capsules yourself, choose vegetarian capsules rather than gelatin to keep the routine vegan.)

Who should consult a doctor before taking MSM?

Speak with your healthcare provider before starting MSM if you are pregnant or breastfeeding, take blood-thinning medication such as warfarin, have kidney disease or impaired kidney function, or are uncertain about interactions with existing prescriptions. No formal drug interactions have been documented in research, but personalized guidance is always the prudent approach.
