MSM — methylsulfonylmethane — is an organic sulfur compound found in small amounts in vegetables, fruits, and meat, which the body uses for collagen, keratin, glutathione, and numerous other sulfur-containing structures. At Plenthera, you’ll find premium MSM in powder form and as capsules — standardized to OptiMSM purity (99.9%) through multiple distillation. Vegan, tasteless, and almost always part of a joint or skin stack.

What is MSM?
MSM (methylsulfonylmethane) is an organic sulfur compound with the formula (CH₃)₂SO₂. Approximately 34% of the molecule consists of sulfur — a mineral the body needs for collagen, keratin, glutathione, and the amino acids cysteine and methionine.
After calcium and phosphorus, sulfur is the third most abundant mineral in the body but receives much less attention in nutrition conversations. It is a structural component of almost all proteins (via cysteine and methionine), of collagen (skin, joints, connective tissue), of keratin (hair, nails), and of glutathione — an antioxidant active in every cell. A chronically low sulfur status is rare with a normal diet, but for specific needs regarding connective tissue, skin, or joints, extra sulfur through MSM supplementation is becoming popular.
MSM occurs naturally in small amounts in food — green vegetables, cruciferous vegetables (broccoli, cabbage), fruits, meat, milk, tea, coffee. However, the amounts are relatively small and susceptible to loss during transport and preparation. Commercial MSM supplements are synthetically produced from DMSO (dimethyl sulfoxide) — the end product is chemically identical to natural MSM in food.
MSM is almost always used in a broader joint or skin context. The classic combination is MSM + glucosamine + chondroitin for joints; for skin, it is often combined with collagen and vitamin C. Also check out our glucosamine category, collagen category, and turmeric category for related products.
Science and EFSA status
MSM has been investigated in hundreds of clinical studies over the past decades, particularly concerning knee osteoarthritis, sports recovery, and skin comfort. The results are generally positive in terms of subjective improvement in pain, mobility, or skin quality, but the studies are often small and methodologically varied. High-quality, large RCTs with MSM as a single product are scarce — much research focuses on combination formulas with glucosamine and chondroitin.
Important: Despite extensive research, EFSA has not yet approved any health claims for MSM. Applications concerning joints and connective tissue were rejected due to insufficient causal evidence based on EFSA's strict criteria. Therefore, we do not make literal claims about the effects of MSM.
MSM is a food supplement, not a medicine. If you are taking blood thinners, are pregnant or breastfeeding, or have any medical conditions, consult a doctor or pharmacist beforehand. The NVWA advises consulting a doctor in case of doubt.
OptiMSM and the quality question
MSM is a commodity product — many suppliers, wide price range. What determines quality is primarily the purification process. Cheap MSM can contain residues from the production process (DMSO residue, impurities in crystal structure). Premium MSM undergoes multiple distillation or crystallization for purities up to 99.9%.
OptiMSM®: A patented American brand (Bergstrom Nutrition) that provides MSM with >99.9% purity and extensive quality control. Listed on the label as a quality marker.
Distillation: The pure MSM becomes gaseous through heating and recondenses — impurities are left behind. Multiple distillation provides higher purity.
At Plenthera, we work with OptiMSM-certified products whenever possible. For those who want certainty about purity: ask for the quality certificate.
The MSM forms at Plenthera
MSM powder (OptiMSM)
Tasteless crystalline powder, mixable with water or juices. Highest purity class. For flexible dosing. Our first-line recommendation.
MSM capsules / tablets
Practical and precisely dosable — 500-1000 mg per capsule. For those who do not want to mix powder.
MSM + glucosamine (joint formula)
Classic combination for those focusing on joints and cartilage.
MSM + collagen + vitamin C (skin/hair/nails formula)
Synergistic beauty stack. Vitamin C is a cofactor in collagen synthesis, MSM provides sulfur for keratin.
MSM + chondroitin + glucosamine + collagen
Premium joint stack — all four building blocks together.
How to use MSM?
Simple basic approach for MSM:
- Determine your goal: maintenance, joints, skin/hair/nails, sports recovery.
- Start with 1,000 mg per day and gradually build up to your target dosage.
- Divide higher dosages (>2 g/day) over 2-3 moments — prevents possible laxative effect.
- Can be taken with or without a meal; avoid late evening if you experience a slight alerting effect.
- Mix MSM powder with water or a drink — tasteless, slightly bitter.
- Combine for maximum effect: joints (+ glucosamine + turmeric), skin (+ collagen + vitamin C).
- Allow at least 6-12 weeks of consistent use for a fair assessment.
- If taking blood thinners, pregnant, or breastfeeding: consult a doctor beforehand.
Myths and misconceptions about MSM
Myth 1: "MSM is a miracle cure for all joint problems."
Incorrect and legally problematic. MSM has no EFSA-recognized claims. Research suggests beneficial effects for some purposes, but it is not conclusive for all individual cases. We do not make literal claims about its effects.
Myth 2: "The more MSM, the faster the results."
Dosages >6 g/day do not provide demonstrable added value for most purposes. Higher dosages may have a mild laxative effect or a slight alerting effect. Start low, build up gradually.
Myth 3: "MSM from food is as effective as a supplement."
Food provides MSM in milligrams per serving (in green vegetables, milk, coffee). A supplement provides grams — a factor of 1,000 difference. For specific goals, supplementation is more practical.
Myth 4: "MSM is the same as sulfur from garlic or onions."
Not entirely. Sulfur from garlic and onions is present in other compounds (allicin, sulfides) with different properties. MSM is a specific standardized organic sulfur compound, not interchangeable with dietary sulfur sources.
Combining MSM with other supplements
MSM is often combined for joint or beauty purposes. Popular combinations include:
- Glucosamine: classic joint combination.
- Collagen: for skin, hair, nails, and joints. MSM provides the sulfur component for collagen building.
- Vitamin C: cofactor in collagen synthesis.
- Turmeric: inflammation modulation alongside MSM building blocks.
- Chondroitin: second classic cartilage building block.
- Omega 3: for joints and general tissue maintenance.
- Magnesium: for muscle and joint health.
Frequently asked questions
What is MSM?
Methylsulfonylmethane — an organic sulfur compound. Naturally occurring in food and used for joints, skin, hair, and nails.
What does MSM do?
MSM provides organic sulfur — a building block for collagen, keratin, glutathione, and amino acids. EFSA claims do not exist — no literal claims about its effects.
How much MSM per day?
Standard: 1,000-3,000 mg/day. Up to 6 g/day for specific purposes. Build up gradually.
When to take MSM?
With or without a meal. Divide higher dosages over 2-3 moments.
Does MSM help with joints?
Clinical research indicates effects — often in combination with glucosamine. EFSA claims do not exist.
Does MSM help with hair and nails?
MSM provides sulfur for keratin. Many users experience a positive effect, but scientific evidence is limited, and EFSA claims do not exist.
What is the difference between MSM and sulfur from food?
MSM is a specific standardized compound. Food provides sulfur in other forms (protein, allicin), in smaller amounts.
