Understanding Methylsulfonylmethane (MSM)
Methylsulfonylmethane, commonly known as MSM, is an organic sulfur-containing compound. It is a metabolite of dimethyl sulfoxide (DMSO) and an integral part of the earth's natural sulfur cycle. Sulfur is an essential mineral for all living organisms and is the eighth most abundant mineral in the human body. It is crucial for the health and regeneration of cells, playing a role in the formation of connective tissues, proteins, and enzymes. While MSM is widely available as a dietary supplement, it is also present in many foods, though usually in very small quantities. The concentration can be significantly reduced by heating, processing, or irradiation, highlighting the importance of consuming fresh, raw foods to maximize dietary intake.
Plant-Based Sources of MSM
Cruciferous and Allium Vegetables
These plant families are well-known for their sulfur-rich compounds and represent some of the most readily available sources of MSM in a plant-based diet. Their pungent flavors often indicate their high sulfur content.
- Garlic: A member of the allium family, garlic is a potent source of organic sulfur compounds, including MSM.
- Onions: Like garlic, onions are part of the allium family and contain notable amounts of MSM.
- Brussels Sprouts: These cruciferous vegetables are cited as natural sources of MSM.
- Broccoli: Another cruciferous powerhouse, broccoli is known to contain MSM.
- Kale: This nutrient-dense leafy green is included among the vegetables containing MSM.
- Cabbage: A staple in many cuisines, cabbage is a good source of MSM, particularly when eaten raw.
- Asparagus: This vegetable has been identified as a natural source of MSM.
Fruits and Grains
While vegetables are often highlighted, certain fruits and grains also contribute to the dietary intake of this important compound.
- Apples: Fresh apples are listed among the fruits that contain MSM.
- Raspberries: These berries are another delicious fruit source of MSM.
- Tomatoes: Found in many variations, fresh tomatoes offer trace amounts of MSM.
- Whole Grains: Some whole grains contain small amounts of MSM.
- Corn: Both sweet corn and field corn have been found to contain detectable levels of MSM.
Other Plant Sources
Beyond common produce, other plant-based items are known for their MSM content.
- Alfalfa Sprouts: Often used in sandwiches and salads, alfalfa sprouts are a noted source of MSM.
- Horsetail (Equisetum arvense): This herbal remedy is one of the more significant plant sources of MSM and has been used traditionally for its health benefits.
- Tea and Coffee: Trace amounts of MSM can be found in tea and coffee, although the brewing process may affect the final concentration.
The Impact of Food Processing on MSM Content
The volatile nature of MSM means that its presence in foods is heavily influenced by how the food is handled and prepared. When food is heated, dried, or frozen, a significant portion of the naturally occurring MSM is lost. For this reason, consuming raw or minimally processed foods is often recommended to maximize the intake of this compound. This poses a challenge, as many of the best sources, such as cruciferous vegetables, are often cooked before consumption.
Comparison of MSM Sources
| Food Type | Example | Form | Estimated MSM Concentration | How Processing Affects MSM |
|---|---|---|---|---|
| Raw Vegetables | Garlic, Broccoli | Raw | Higher | Minimal loss |
| Cooked Vegetables | Garlic, Broccoli | Cooked | Significantly Lower | Volatile MSM is lost during heating |
| Fresh Fruit | Raspberries, Apples | Raw | Lower | Minimal loss |
| Processed Fruit Juice | Apple Juice | Juiced/Pasteurized | Extremely Low | High heat pasteurization destroys most MSM |
| Fresh Grains | Wheat Germ | Raw | Lower | Moderate loss (grinding) |
| Baked Goods | Bread | Processed | Extremely Low | High heat during baking destroys MSM |
| Herbal Tea | Horsetail | Brewed | Variable (Low) | Infusing in hot water leads to some loss |
| Supplements | MSM Capsules | Crystalline Powder | High | Purified for maximum concentration |
Maximizing Your MSM Intake from Plants
To increase your dietary intake of methylsulfonylmethane from plant sources, focus on consuming fresh, raw, and minimally processed foods. Here are some actionable tips:
- Prioritize Raw Consumption: Incorporate more raw vegetables into your diet through salads, smoothies, or raw snacks. For instance, raw garlic and onions can be chopped into salsas or dressings.
- Lightly Steam Vegetables: If cooking is necessary, opt for light steaming instead of boiling or high-heat roasting. This can help preserve more of the heat-sensitive MSM content.
- Enjoy Fresh Fruits: Eat fresh fruits like apples and raspberries directly rather than opting for processed juice versions.
- Add Sprouts to Meals: Top salads and sandwiches with fresh alfalfa sprouts to boost your MSM intake.
- Explore Fermented Foods: While processing often reduces MSM, some forms of fermentation might offer alternatives, but research is less conclusive here. Stick to raw whole foods for the most reliable sources.

Conclusion
While plants do contain methylsulfonylmethane, the amounts are typically small and highly susceptible to heat and processing. For those looking to increase their MSM intake naturally, the best approach is to focus on a diet rich in raw, fresh fruits and vegetables, particularly cruciferous and allium varieties. These include garlic, onions, broccoli, kale, and alfalfa sprouts. For higher, more consistent doses, dietary supplementation is often necessary, but incorporating natural plant sources is a healthful and delicious way to support your body's sulfur needs.
Frequently Asked Questions
What are the primary sources of MSM in a plant-based diet? Garlic, onions, and cruciferous vegetables like broccoli and kale are among the best plant sources of methylsulfonylmethane when consumed raw.
Does cooking destroy the MSM in vegetables? Yes, MSM is a volatile compound, and its concentration is significantly reduced by heat, freezing, and other forms of food processing.
Can I get enough MSM from my diet alone? While possible, it can be challenging to obtain therapeutically significant amounts of MSM from diet alone due to its low concentration and vulnerability to processing. For higher doses, supplements are often recommended.
Is there a difference between MSM from plants and a supplement? No, the commercially produced MSM used in supplements is chemically identical to the naturally occurring compound found in plants. The main difference is the concentration and dose.
What benefits are associated with MSM? MSM has anti-inflammatory and antioxidant properties, which have led to its use for joint pain, osteoarthritis, exercise recovery, skin health, and immune support.
Are fruits a good source of MSM? Fruits like raspberries, apples, and tomatoes contain small amounts of MSM, but generally less than the richer vegetable sources. They are still a valuable part of a balanced diet.
Do whole grains provide MSM? Yes, some whole grains do contain a small amount of MSM, though like other plant sources, the amount is minimal and can be affected by processing.
