It's supposed to obviously boost the immune system. I'm HORRIBLE with taking stuff like this, so I'm not really sure I took it regularly enough to realize the benefits. I still have some left, so maybe I'll take the rest of it.
I actually have been really sticking with the Lean Muscle Meals, the iodine for hypothyroidism, and a couple of other things, though, and I have noticed a definite difference in my energy level.
