I would suggest you drink either Reliv vitamins or a product called Body Balance. I do not sell these but drink them myself. Both are excellent products to keep your immmune system at its best and much better than taking pills. You have to get these from distributors. Body Balance is glyconutrients and Aloe Vera from sea vegetables and contains every vitamin your body needs. Reliv is a powder and also contains every vitamin your body needs. You can check these out at Reliv.com or Body Balance.com to learn more. Hope this helps.
