It seems like everyone is getting sick!
I DO NOT recommend wasting your money taking a vitamin C supplement that is isolated vitamin C.
However, I highly recommend taking New Chapter Organics Activated C Food Complex. It works well because it is food based and has great things like tumeric, spinach, elderberry, shitake mushroom, ginger, etc in it.
If you workout, I recommend taking this because it can reduce the exercise-induced oxidative damage and also enhance the health-promoting effects of exercise.
