My children take it on a daily basis and they rarely develop a cold

However i find that taking this supplement helps me recover quicker than without taking it

I only use it 23 caps 2 3 times a day for a few days only when feeling like i might get sick or to avoid the bug that everyone else is fighting that and extra vit c doses does the trick almost every time or at least shortens the time down

If i a cold i never have to take days off unless i feel im contagious
