Very impressed with this product. As an Equine professional working in the deep humid south, Anhidrosis is a big problem. I have tried everything from dark beer, papaya juice to “guarrenteed” supplements. Some work for a while and some don’t work at all… However!!! Within a week, Leo was sweating in normal patterns. I was amazed!! He has been sweating now (even at rest) for over a month! There are no extra calories and Leo loves the salty taste. I recommend trying this product for anti-sweaters!
