Interesting observation I'd like to bring forward...Junior is my FEI horse and is insulin resistant. After a lengthy conversation with Dr. Steve Angelos, is realized I've been treating his condition ineffectively. Although I am feeding the correct feed by modifying sugars and starch, I was not supplementing nearly enough chromium. My misunderstanding was in the amount of Magnesium used versus the amount of chromium. I continuously increased the amount of Magnesium Junior was getting without ever considering the other. I switched Junior to "Smart IR" and he's like a different horse! His mood is much more upbeat and his reaction time to aids during training is lightening quick. Maybe it's coincidence, but I'm not so sure. The change was noticeable after only 2 days on the new supplement.
