I can’t say for certain that the Jiaogulan and Spirulina I’m feeding is having any positive effect but I like the concept of it so will continue to feed it. That being said, I have noticed the more pinky colour of my mare’s tongue and gums after feeding it like the write up describes. Overall, her energy levels are up but it may be to the overall MadBarn diet I am feeding her (alfalfa, beet pulp, spirulina, jiaogulan, AminoTrace+ and w-3 oil). It doesn’t have a very strong smell and is fed in small doses so it is easily added to feed for a picky eater.
