MSM Powder: What It Is and How People Take It

TL;DR: MSM powder is methylsulfonylmethane, an organic sulphur compound sold as a white, crystalline powder with a bitter taste. It occurs naturally in small amounts in some foods and drinks, and the supplement form is made in a factory and purified. People stir it into water or juice, or get it as one ingredient inside a blend.

Ever picked up a tub of joint health supplements and wondered what the three letters MSM actually stand for?

It turns up on a lot of labels, usually without much explanation. Here's what it is, where it comes from and how people use it.

What is MSM powder?

MSM is short for methylsulfonylmethane. It's a small organic compound built from carbon, hydrogen, oxygen and sulphur.

Chemists also call it dimethyl sulfone. You'll see either name on ingredient lists, but MSM is by far the most common.

As a supplement, it comes as a fine white crystalline powder. It has almost no smell and dissolves easily in water.

You can buy it on its own as a single-ingredient powder, or find it as one line in a multi-ingredient formula.

Action: check the ingredient panel for "MSM" or "methylsulfonylmethane" so you know which one you're looking at.

What is MSM made from?

MSM occurs naturally in small amounts in some everyday foods and drinks, including milk, coffee, tea and some fruits and vegetables.

Those amounts are tiny, so the MSM in a tub isn't extracted from food.

Instead, it's made in a factory. The usual process starts with a related compound, dimethyl sulfoxide (DMSO), which is reacted with hydrogen peroxide to form MSM.

The raw MSM is then purified, commonly by distillation or crystallisation, and dried into the powder you see in the tub.

Action: if purity matters to you, look for brands that state how their MSM is purified on the label or website.

What does MSM powder taste like?

Honestly? Bitter.

On its own, MSM has a sharp, slightly bitter taste. The crystals dissolve quickly, so it isn't gritty once stirred in.

The bitterness is the main reason many people don't take it straight. A small amount in a large glass of water is milder than the same amount in a splash.

In flavoured blends, the taste is usually covered by fruit or citrus flavours and a sweetener.

Action: if you're trying plain MSM, start with a full glass of liquid rather than a small shot.

How do people take MSM powder?

Most people stir it into a glass of water or juice and drink it straight away. Citrus juice is a popular choice because it masks the bitterness.

Others add it to a smoothie with stronger flavours like berries or banana.

Because it dissolves so readily, it doesn't need a blender. A spoon and a quick stir does the job.

Many people fold it into an existing habit, like a morning glass of water.

Follow the serve size on the label of the product you buy, as amounts vary between brands.

Action: pair it with a drink you already have every day so it becomes automatic.

Why is MSM combined with glucosamine and chondroitin?

MSM, glucosamine and chondroitin are often sold together in one formula. It's a long-standing pairing on supplement shelves.

For a lot of buyers, the appeal is convenience: one scoop from one tub instead of measuring out three or four separate powders.

Some formulas go further and add collagen, turmeric extract and vitamin C. Our collagen supplement for joints, Complete Joint Care, is one example.

It's a powder, and each 5 g serve contains hydrolysed bovine collagen 2,550 mg, glucosamine sulphate 750 mg, MSM 750 mg, chondroitin sulphate 200 mg, turmeric extract (95% curcuminoids) 50 mg and vitamin C 40 mg.

There are 40 serves per 200 g tub, with a natural lemon flavour sweetened with monk fruit. It contains shellfish and shark, and is manufactured in Australia from imported ingredients.

Action: read the allergen line on any blend before you buy, as some of these ingredients come from marine sources.

MSM powder or capsules?

Both contain the same compound, so it comes down to how you like to take things.

Powder lets you adjust the amount and mix it into a drink. The trade-off is the bitter taste if it's unflavoured.

Capsules skip the taste completely. But each capsule holds only a small amount of powder, so a full serve can mean swallowing several at once.

If you already have a daily shake or juice, powder usually fits in easily. If you'd rather not taste anything, capsules may suit you better.

Action: choose the format you'll actually keep using, then compare labels by the amount of MSM per serve.

What to do next

Now you know what MSM is, the label makes more sense. It's a bitter, white sulphur compound, made and purified for supplements, and usually stirred into a drink.

Look at the amount per serve, check the allergen line, and pick a format that fits your routine. Alongside that, keep the basics in place: a wide variety of foods, regular movement and good sleep. If you have questions about whether a supplement suits you, have a chat with your GP or a dietitian.
