Hyaluronan is a natural component of synovial fluid, the substance that cushions and lubricates joints, and its levels can decline with age and activity. This liquid formula is designed to deliver hyaluronic acid orally as a daily alternative to capsules or powders. The 11.5 oz bottle is grape flavored, sugar-free, gluten-free, and vegan, and it is produced in the United States. A common regimen starts with a short loading period at a higher daily amount, followed by a smaller ongoing maintenance dose. The liquid can be taken directly by mouth or mixed into water, and it requires no preparation or assembly. Because of its grape flavoring, this particular formula is intended for human use rather than for dogs.
