OxyMin MSM 500g contains MSM (methylsulfonylmethane), also known as organic or biological sulphur. It is supplied as a micro-crystalline powder and is described as 100% pure pharmaceutical-grade MSM, with no fillers or flowing agents. The MSM is derived from trees using DMSO, a by-product of paper manufacture.
Raw material batches are tested for organic volatile impurities and heavy metals, including lead, arsenic and mercury. The product is packed in Australia in a tamper-proof, airtight container at an AQIS-approved facility. Each batch is also micro-tested after packaging for conditions such as salmonella.
