For aging eyes and cataract prevention

Posted by Reviewer1148576 on Dec 07, 2009

Our 9 year old dog had developed an opaque blue covering over his eyes. Giving him the B2 plus B-50 every day resulted in about 70% improvement in 4 weeks and 95% improvement after 7 weeks. His eyes are back to a very definite clear brown and he is seeing clearly again.

A quality product if you don't mind measuring out the ingredients.

Easy to use

I find the powders the easiest to use by adding them to my morning smoothie. B2 and B3 are the primary ingredients in ATP-Cofactors which help your thyroid.
