Look up the side effects for each of the things mentioned separately. They're all just vitamins and supplements, so I don't imagine that any potential side effects would be too harsh unless you took more than the recommended dosage.
I took the Holy Grail combo for a while back in college, and I didn't notice anything negative. I did see some benefits, particularly relating to the amount of pre-cum I produced.
