Very good supplement, nice lemon flavor, easily soluble in water or juice. Helps with mental and intellectual work. I did not see improvement in vision (I am presbyopic due to age).

I had optic neuritis + a blood vessel in my eye burst, resulting in the loss of my vision. Besides the cortisone they gave me at the hospital, my ophthalmologist recommended it for good circulation of the blood vessels in the eye. I don't know if it was coincidental, but since I started taking it, I gradually began to see again. My family members who took it for a few days told me that they started to see more clearly and the colors became more vivid.
