For aging eyes and cataract prevention

Posted by iHerb Customer on Dec 07, 2009 | Verified Purchase

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.

Thanks for your feedback!

measuring spoon is akward

Posted by iHerb Customer on May 10, 2010 | Verified Purchase

The product seems to be fine, but the measuring spoon is very akward to use. The recommended does is half of the spoon, which is not easy to measure.

Thanks for your feedback!

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.
