    Started taking Mega Men Sport, and started to feel as i would pass out. Tightness in my chest and breathing alittle harder. I have no heart condition, had a full physical before starting on this product. Also have worked in the heathcare feild for over 30yrs. What could be in this product that could cause this problem?

    I entered the Harrisburg GNC store looking for Magnezium Citrate. The worker told me thet he never heard of magnezium citrate and asked me what magnezium is used for. He didn’t know anything about magnezium. I told him thank you and that I would order it online like I usually do. I couldn’t believe that someone working in a vitamin store didn’t even know what magnezium was.
    I won’t be going back there.

    I can’t find a phone number to ask a question (only sale related numbers) and the GNC question page doesn’t work. I want to know where their alpha-lipoic acid comes from.
