I am a little confused. I am part of a marching band that practices in the heat very hard and i naturally am very sweaty. Since last season i have noticed a very distinct orange sweat that accumulates on my skin. Ive tried everything to figure out what it was. I only take a vanilla protein powder supplement and a multivitamin daily, both of which i stopped last season to see if it helped, and it didn't. I also do not notice the orange sweat during the offseason when i train. Could this be some other dietary excess? Im not sure if it something to be worried out, but i would like to know what causes it.
