Optimal quality controls - Pure raw material with laboratory report
100% Pure raw material - With purity analysis report by accredited external laboratories
At HSN, we have a commitment to our customers, which is to use the best ingredients for the development of our own food supplements.
Regarding methylsulfonylmethane, we have searched the market to find a raw material of the highest quality, one that meets our required standards of purity. What does this mean?
We have come across raw materials marketed in Europe, and widely chosen by other companies for MSM formulas, which had purity values that we consider unacceptable.
At HSN, we wanted to find a pure compound, and after months of searching, we found it.
Our raw material, the pure MSM that you find in this product, has undergone external laboratory tests, with no connection to HSN. These prove through authenticated analysis systems carried out by the group of experts at the headquarters in Poland that:
The net MSM content is 95%.
This means that its purity is maximum and total so in anhydrous content it would be close to 100% purity.

At HSN, you have at your disposal the best raw materials and 100% validated products that offer you the best quality for your daily diet.
No additives - Clean label formula - Authentic RAW for your highest purity blends
Commercially available MSM powders usually contain additives in their formulation, which often serve aesthetic dispersion functions or are used to mask the natural taste of methylsulfonylmethane.
At HSN, we have the RAW line available so that you can enjoy what you are looking for: Products made only from the pure compound, without other ingredients in its composition, because you don't want them and because you don't need them. At HSN, we bring you the highest purity food supplements, in pure powder presentations to make your own raw blends at home.
Granulometry-controlled MSM solubility - How to mix it to obtain a smooth drink?
Granulometry is the system that studies the particle size of food supplement powders, and how this affects their dispersion.
Many methylsulfonylmethane supplements are extremely difficult to mix, but not HSN Raw. Our MSM mixes perfectly because its particle size is ideal for homogeneous dilution in water.
However, we would like to clarify that MSM, as well as other compounds such as Magnesium or Arginine, do not mix homogeneously in water to make a 'shake' as can happen with a protein.
Instead, they are suspended, making the powder 'float' evenly in the drink. If taken when mixed, you will not notice any of the MSM, as it is so fine that it can be consumed without a gritty sensation. If left to stand, our MSM, due to the granulometry of its powder, takes longer to settle to the bottom of the glass, which, when it does, only requires stirring the drink again to integrate it.
Free of Genetically Modified Organisms. Compound suitable for vegan diets.
MSM often contains Genetically Modified Organisms, as they are the most convenient way to develop this form of organic sulphur for food supplements.
At HSN we reject the use of GMOs, as their nutritional safety, although established, continues to be questioned by expert groups. In addition, their use involves significant harm to the environment, which is not in line with our policy of environmental commitment.
Therefore, our pure MSM powder, as well as any other food supplement in our catalogue, is certified GMO-free.
In addition, the MSM by HSN RawSeries has been manufactured without the use or presence of animal ingredients, allowing it to obtain, in addition to a pure compound, a vegan one.
No colourings, flavourings, or preservatives - Only pure MSM of the highest quality
We do not use anything that masks the presence or natural taste of our pure MSM.
Unlike other companies that sell 'pure' compounds in powder form that then contain ingredients that either mask the flavour or enhance the presence of the compound, HSN offers you an authentically pure product, with no catch or gimmick.
Enjoy 100% pure msm with no additives.

It can be combined with other compounds to obtain your own best formula
Methylsulfonylmethane is a well-known compound of proven and appreciated nutritional quality, especially by athletes and people exposed to high physical demands.
It is commonly combined with two other compounds, with which it forms a synergistic 3-in-1 mixture that is possibly the most famous and widely used food supplement stack (in fact you can find it combined in tablets in our Evoflex).
In combination with Glucosamine Sulphate and Chondroitin Sulphate it forms the ideal mix, which you can prepare at home with 100% pure and certified HSN RAW products.
Methylsulfonylmethane flavour and HSN recommendations
MSM is an organic compound derived from sulphur, and as such has a characteristic sulphur smell.
It is advisable not to mix this food supplement in protein shakes or other food preparations where flavour preservation is desired, as MSM can significantly alter the flavour and make it more bitter.
MSM has a sour and intensely bitter taste.

One way to cover up the taste of MSM and turn it into a delicious drink is to combine it with our specific flavouring product for amino acids and sports drinks.
Ideal fruity flavours to hide the taste of methylsulphonylmethane!
