EyeFactor HA is a major new supplement for the eyes. It includes Lutein and Billberry, supplements that are helpful for eye health. However, most importantly, it contains Hyaluronic Acid. 95% of the fluid inside the eye is Hyaluronic acid! HA plays a major role in maintaining the health of ocular tissues such as the cornea, the retina, and the vitreous fluid that fills the inside of the eye. Consequently Hyaluronic acid is also helpful for gums, hair, skin, and joints.
