Not to my knowledge. Highly unlikely double check with your doc also.
Is it reasonable to take L-lysine capsules daily (about 1500mg) to prevent latent herpese viruses? Any side-effects should I be aware of?
Yes, but it's not. Necessarily effective. L-lysine may decrease the number & duration of HSV I (cold) sore outbreaks, but not necessarily HSV II (genital herpes). l-lysine can increase the amount of calcium your body absorbs. While food (like dairy) isn't a problem, a healthy young guy like you shouldn't take calcium supplements at the same time. This includes calcium-containing antacids.
