Have not been sick in years with this supplement mix, anyone else?

I started taking omega-3s and magnesium glycinate in the evenings along with my multivitamin and vitamin d and I have not been super sick for 5 years now (one exception below). My family gets sick but I never catch it.

I did stop the routine and started taking my omega-3 in the mornings about a year and a half ago and got the worst head cold, but I was super stressed out at that time too so could be either or, but I've been stressed out since and I never get more than just the sense of an oncoming cold. Go to bed early, get a good sleep and then avoid it.

Anyone else find this magic In the omega-3 magnesium glycinate mix?
