LubriSyn HA is a liquid joint supplement built around a single active ingredient, hyaluronic acid, delivered as sodium hyaluronate sourced from a non-animal, microbial fermentation process rather than animal tissue. Hyaluronic acid is a natural component of synovial fluid, the substance that cushions cartilage surfaces and allows joints to move smoothly, and levels of it can decline with age, exercise, or normal wear. The formula is a clear, unflavored liquid mixed with water, glycerin, xanthan gum, citric acid, and potassium sorbate, and it is given by mouth or top-dressed onto food once daily. Each bottle is intended for ongoing daily use rather than occasional dosing, with amounts adjusted by species and body weight. The product is vegan, gluten free, and free of BPA, and is intended for animal use only. It should be stored at room temperature and kept out of reach of children.
