Hyaluronic acid is part of what fills the space between the cells, which is referred to as the extracellular matrix or ECM. As an analogy, it’s rather like a traffic regulator between buildings (the cells) in the urban jungle. Hyaluronic acid plays a major role in ECM by regulating fluid storage, cell movement and pressure while keeping pathways between the cells unobstructed.
It used to be thought of as an artificial lubricant in synovial joints, but we’re now more aware of its beneficial effects on the chemical composition of damaged synovial fluid.
We now have well tolerated synthetic drugs that have been tested for years in theory and in clinical practice for effective pain relief.
