Dairy free, Organic, Wheat free, Methylsulphonylmethane (MSM) is a naturally occurring organic sulphur.- Plantforce® MSM (methylsulfonyl methane) is not made from petrochemicals, but is extracted from plant material. You can easily have long discussions about the difference in MSM coming from plant material or petrochemicals. We have taken two considerations in creating these products: – That we personally prefer MSM from plant material, and not MSM chemically synthesized from petrochemicals (and which is unfortunately often incorrectly marketed as a natural source). This is confirmed by carbon 14 testing. – Secondly, we can see that the purity and quality of our MSM are at the top, which is documented by our third-party lab test for heavy metals, that shows we have no detectable heavy metals in this product. MSM supplements, especially ours, are very powerful and should be used in short courses as strong detoxing. These detoxes should be used with caution as there can be initial flu-like symptoms as the toxins are cleared from your body.
