Put Your Immune System OnGuard®

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.

 

Shield Your Health with OnGuard®
With all the challenges that plague us today, you need to support your immune system now more than ever. The OnGuard formula goes beyond vitamins with Colostrum, rich in antibodies, Lo Han fruit extract used for centuries to preserve health, and MaitakeGold 404â„¢ Mushrooms – proven “immune active” by University Scientists.

Take OnGuard every day to stay well, especially when you are on the go and exposed to the public. You’ll feel better and stay healthier!

 

You Are Under Attack by Germs Daily!


Germs are around us always, in the air we breathe, the surfaces we touch, and from the people we come in contact with each day.  Exposure to others in closed spaces increases risk: offices, stores, airplanes, trains, theaters, churches, etc.

If someone coughs or sneezes, germ droplets can float in the air and assault the next victim. When you least expect it, you could be exposed to deadly bacteria and viruses. You need to keep your immune system ONGUARD!

 

Nobel Prize Laureate says OnGuard Works!
Dr. Andrew Schally is a world-renowned Scientist acclaimed for his ground-breaking health discoveries. He has published over 3,000 scientific papers, is 97 years old, and works all day, starting his research at 7am.

 

Dr Andrew Schally quote about MDR OnGuard


Put the Odds in Your Favor

Your good health relies on your body’s immune surveillance system. It must identify and remove dangerous invaders 24/7 to keep you in the best of health. MDR OnGuard contains powerful compounds from nature that can provide extraordinary immune support.

  • MycoFusion: Proven, patented mushroom extract enhances immune cell activity and increases cell defenses.
  • Colostrum: Transfers protective antibodies and immune factors derived from mother cow’s first milk for her calves.
  • Lo Han Kuo: Chinese melon extract “Lo Han Kuo” prized for centuries to promote good health and longevity.

MycoFusionâ„¢ Powers Up Your Immunity

Maitake mushrooms in MDR OnGuard

OnGuard’s main ingredient MycoFusionâ„¢ combines Shitake Mushroom with a special extract derived from Maitake mushrooms. Japanese researcher Dr. Hiroaki Nanba, PhD. discovered that certain fractions isolated from Maitake mushrooms provided extraordinary immune-enhancing benefits. Naturopathic Doctors, Nutritionists, and medical centers like Memorial-Sloan Kettering Center in New York have recognized MaitakeGold 404â„¢ for its ability to activate immune defenses.

The University of Louisville confirmed that MycoFusionâ„¢ is rich in Beta-Glucans that are “immune active”. That means they can help activate your immune cells to be ready to defend you. Dr. Nanba’s discovery of MaitakeGold 404â„¢ was such a great advance that it was granted U.S. Patent #5,854,404, so there is nothing like it! Maitake Mushrooms can activate T-cells vital to the body’s immune arsenal. It’s one of the reasons why so many people enjoy great health from taking MDR OnGuard® Immune Defense.

 

Fortified with Colostrum Rich in Antibodies

Colostrum in MDR OnGuard

Colostrum is the first milk produced by Mother cows to transfer their protective antibodies to their vulnerable newborn calves. This milk occurs only the first few days after a cow gives birth and is extremely rich in powerful immune factors.

Colostrum has been cited in hundreds of scientific medical journals for its effectiveness in improving health. From gut health to respiratory health, to overall wellness and performance, Colostrum has proven to be highly valuable.

Pure. Safe. Made in the USA. The Colostrum used in MDR OnGuard is certified as Grade A pasteurized and collected solely from US dairies that ensure it is free of Artificial Hormones, Antibiotics, Pesticides, GMO, and BSE.

 

Lo Han Melon Helps You Feel Your Best

Frequently Asked Questions

What’s the recommended use?

  • Take one OnGuard capsule daily to support your immune system. Take one in the AM and one in the PM for peace of mind if you are run down or have immune challenges. The moment you suspect you are not feeling well, or have been exposed in public places, you may increase your dosage to 4 capsules per day (one every 6 hours).

Is OnGuard safe to take each day?

  • Yes. It should be part of your preventive health supplementation regimen. The biggest advantage of OnGuard is that, unlike a popular herbal immune booster like Echinacea (a ragweed), OnGuard can be taken every day, for long periods – before, during, and after exposure to germs.

*All recommendations are subject to your health care provider’s approval as with any supplement.

If I am on blood thinners, can I take OnGuard?

  • You can take 1-2 capsules a day but do not exceed this dosage. Mushroom extracts may thin the blood, so although this supports healthy circulation for most people, for those taking blood thinners the added anti-coagulation effects must be considered and discussed with your physician.

*All recommendations are subject to your health care provider’s approval as with any supplement.

If I am lactose intolerant can I take OnGuard?

  • Most likely yes. OnGuard® contains Colostrum, a natural milk compound which does contain a very small amount of lactose. Most people who are lactose intolerant take OnGuard® with no difficulty. If you are ALLERGIC to milk or mushrooms do not take OnGuard®.

What’s the key to staying healthy?

  • Supporting your immune system every day with a healthy diet, rest, frequent washing your hands, wearing a face mask in close public places and taking OnGuard® are the keys to staying healthy at this time.

    My friends used to laugh at me because I always seem to catch everything. I was always missing events and work days. I went to a Doctor and he tested my immune system and said it was weaker than average. He recommended the MDR OnGuard formula because he said it helped his other patients. I started taking one with breakfast and one before bed. I started feeling stronger and better. Now I stay healthier than my friends! I will never be without OnGuard. Thank you MDR. OnGuard changed my life!
