I have an over-anxious tb senior with severe arthritis. His anxiety and pacing was causing nasty arthritis flares, and decided to try him on this to see if it would make a difference. For the first time in the 10 years I’ve owned him, my gelding enjoys turnout without pacing all day and is very level headed and calm. I now try this on all my anxious/nervous horses. Sometimes I have success, sometimes I don’t. It’s dependent if the horse is deficient. But for those that are, this does the trick. Have had many successes with it.

I wasn't expecting much but this really did take the edge off without making my horse dopy. Its just like she could focus better. Will be recommending this to everyone who likes riding rocket ships but doesn't bounce as well as they used to.

I have had my TB on this supplement since I purchased him. So I can't really tell if it chilled him out or if he was just a pretty chill boy from the outset. That said, it's a good source of B1 and the price is reasonable so I will keep him on it.,
