"I know there is no magic product that can immediately boost your immune system, but as we all try and stay healthy, I figure taking an immune support vitamin can't hurt. My sister-in-law, who has two young kids, swears by Rainbow Light Counter Attack ($18 for 30 tablets) so I had to give them a try. I have been taking two a day along with a Rainbow Light Women's One Multivitamin ($45 for 90 tablets) and the Rainbow Light Gummy Vitamin C Slices ($9 for 90 slices). Since my diet has been all over the place lately, it's good to know I'm getting a good dose of vitamins at least in pill form." — Christina Stiehl, senior editor, Fitness
