Nature’s Way brings you Hydraplenish with Methyl Sulfonyl Methane (MSM), a supplement that contains the patented BioCell Collagen II complex to encourage healthy connective tissue and synovial fluid (a clear fluid secreted for lubrication by membranes in joints and tendons). It adds Plus OptiMSM to support healthy hair, skin, nails and joints. The Hydraplenish formula has superior bioavailability and a lower molecular weight than other sources of hyaluronic acid. As such, this product can moisturize and rejuvenate your skin from the inside, at the same time lubricating and cushioning your joints.
