Supplement Allergy?

I know that this may sound a little strange, but has anyone a allergic type reaction to taking a supplement? I’ve had facial redness off and on for about six months now. So much that co-workers use to remark about my sunburn. And this would be hours after a workout. I knew it wasn’t the sun causing this and living in the Northeast, I’m not getting any sun riding indoors. I haven’t made major changes to my diet and can not pinpoint any one food as the cause.

I’ve been using CarboPro, Recover ammino tabs and Vantage, along with Endorox after a workout for several years now. Today after a ride the ‘sunburn’ returned. Because my training had been kind of light last month, I was taking less supplements and noticed less redness. So it kind of hit me…must be those pills.

BTW. Went to my local doctor who prescribed a cream, told me to avoid caffeine, spicy food and alcohol. I just think there may be a connection between the exercises and/or supplements and the problem.

Has anyone else had a similar expierence ?

Thanks for any imput.
