Good health relies on your body's immune system to guard against germs. OnGuard contains powerful compounds from nature that can provide extraordinary immune support.

Today we are under attack! A strong immune system is crucial. But, how good is your immune system? Many things can weaken your immunity:

If you don't eat right Lack sufficient sleep Don't have adequate levels of Vitamin A, D, or Zinc Suffer with certain chronic medical issues Are over 65 years of age

No matter how healthy you are, with advancing age your immune system declines. When you get rundown, older, or weakened by stress, latent viruses within you can resurface.

We have a friend who is 85 years old and has gone through several bouts of cancer and his immune system, as you can imagine is very sensitive and not as strong as he would like it to be. He has a Caregiver and she ended up giving him a cold. He was very upset! We ran over a bottle of OnGuard to him right away, because he had just gotten the cold the day before we spoke with him. We gave him instruction to take 4 capsules (1 every couple of hours) to get it into his system on the first day and the next day, when we called to ask how he was, he siad the following: " I want to thank you so much!!! I feel 1 million times better. I believe I actually don't have the cold anymore and then we instructed him to keep taking 2 per day. He was so excited that he told us, he had already ordered another bottle. Seriously!!! This was the best news of the day for us, that On Guard Immune Defense helped this precious man who had a weakened immune system, stay sttong and healthy that day and from this moment forward!
