Boost Your Immunity

Be ready for back to school by knowing how to shore up your immunity to help fight this year’s cold and cough germs. 

Have you ever noticed that when there’s a bug around your office, not everyone “gets” it? Somebody is out for 10 days, someone else for a half day and some people don’t even get sidelined at all. Think about it. They’ve all been exposed to the same germ. So, why does this happen?

It probably happens for the exact same reason that some houses get knocked down in a hurricane and some remain still standing, Some houses are made of brick and steel with hurricane shutters while others are made of much flimsier materials. Which ones survive the storm and which ones don’t has everything to do with how well they were built.

In the same way, if your immune system is well nourished and healthy, it will withstand challenges a lot better. Those of us lucky enough not to get sick stay healthy because our immune system is able to just bat the challenge aside, or at the very least, handle it and recover quickly. Remember, your health isn’t measured by whether or not you get the cold or cough; it’s measured by how well your body handles it if you do get it, and by how quickly your body recovers.


I take a whole-body approach to building immunity, which means immune-boosting foods (such as garlic) and supplements which can strengthen your immune system. At the first sign of a cold, I start adding these supplements and foods:

  • Zinc. Your cells need this mineral to fight bacteria and viruses. And it’s important in the development of white blood cells, which are part of your immune system. Your body has no specific storage sites for zinc, so take it on a daily basis during cold season. If you do get sick, zinc might help shorten the length of your illness. I recommend 15mg a day during “regular” times and 50mg a day at the first sign of a cold. Zinc picolinate has been well-studied, and is the most absorbable. Look for one without copper added.

  • Echinacea. This herb is used to fight the cold and other upper respiratory infections. Take it at the first sign of symptoms. It might keep the cold from developing or make symptoms less severe. Reduce usage as symptoms improve.

  • Cherries and other berries. Almost every cold is accompanied by inflammation. Cherries and berries are filled with compounds called anthocyanins, which are highly anti-inflammatory. All berries are great, but remember to go organic if you choose strawberries as they are consistently on the Environmental Working Group’s list of most contaminated produce.

  • Black Elderberry. One of the most powerful berries in the world is black elderberry. But, unfortunately, you won’t find black elderberries at the grocery store because they are so tart and bitter that they are seldom eaten fresh. What you will find is a marvelous extract of black elderberry, sold over-the-counter as Sambucol. I added Sambucol to the all-new, revised and expanded 10th anniversary edition of my best-selling book, The 150 Healthiest Foods on Earth. Black elderberry is good to take even if you’re not sick, because it helps to turn up the dials on your very complex immune system.

  • Vitamin C. Vitamin C is one of the most researched vitamins when it comes to boosting the immune system. It’s a highly effective antioxidant that helps protect against the free radicals generated by the immune cells to kill pathogens. Vitamin C has also been shown to increase the function and production of important immune system components such as leukocytes, phagocytes and neutrophils. Neutrophils—which attack foreign invaders such as bacteria and viruses—are particularly stimulated by vitamin C. It actually turbocharges the whole process of healing. I suggest getting it from a diet high in fruits and vegetables.

  • Garlic. Garlic has been used since ancient times to ward off colds. I don’t recommend wearing it around your neck, but supplementing your diet with fresh garlic or garlic extract may help keep all those nasty germs away. Cooking with garlic is one easy way.

  • Vitamin A. It’s an immune system booster like almost nothing else, even though few people outside the health professions know this. I recommend 50,000 IUs for three days in a row if you start to feel something coming on. Yes, that’s a high dose but it’s only for three days, and it’s quite effective.


This combination of foods and supplements will go a long way toward keeping you healthy by boosting your immune system. If you do get sick,

  • make sure to get lots of sleep
  • try using a Neti pot to rinse your nasal cavity and soothe your sinuses
  • gargle with hot water, sea salt, lemon juice and cayenne pepper
  • spread on a mentholated rub
  • gobble down some homemade chicken soup

Every one of these is helpful and, done together, and with the right supplements, the effect is synergistic.
