Digest Series: Boosting the Immune System, Part 3

Simple things you can do to keep the immune system in tip-top shape

In the last installment I provided an 60,000 foot overview of the vast and complicated immune system. We know that the immune system only has one goal and that is to protect us from being overcome with bugs and germs. In other words, keep you alive and kicking. But why does it fail us at times?

One way our immune system can become weakend is by not having enough white blood cells. If your body doesn’t produce enough white blood cells its like having an inadequate army. Your immune system doesn’t have enough troops, tanks, aircraft and ammunition to take on a foreign invasion. When this happens, you get sick‚ and if your immune systems weakens to a the point of failing, you can get very, very sick.

There are certain factors, some in our control and some not, that can contribute to your immune system weakening which can be like an open invitation to an all-you-can-eat buffet for germs, bugs, virus, disease, and parasites.


Some of the things out of our immediate control are conditions such as Hodgkin’s disease, malaria and leukemia, which affect the bone marrow’s ability to produce a sufficient amount of white blood cells.

Free Radicals

If free radicals weren’t bad enough, those greedy, little atoms with unpaired electrons, which make us grow old and die, also take a toll on our immune system. Found in the air we breathe, water we drink and food we eat, free radicals damage arterial walls and knock out communication between certain white blood cells (whose job it is to alert to potential danger).

Medical Treatments

In addition, many medical treatments can cause your immune system to slow down. For example, the use and overuse of antibiotics is widely believed to be one of these. Over time we build up a resistance to these antibiotics if we take too much for too long. This allows us to become susceptible to infections you once had, got over and thought you’d never see again. Other medical treatments such as radiation and chemotherapy as well as immune -suppresive drugs also contribute to a weakened immune system.).

Other factors that weaken our immune system can be controlled. These include:

Poor Sleep

Many researchers believe that during sleep our energy is directed away from our routine daily functions and toward recharging the immune system. This is while it is often suggested that we sleep as much as we can while we’re sick. It’s no surprise then to read the studies, which report that people who consistently get enough sleep, night after night, have less illness and fight off sickness quicker.).

Poor Diet & Nutrient Deficiency

This should be a no-brainer. When you are only putting in bad stuff what do you think is going to happen? Bad stuff. For thousands of years the human body pretty much ate fresh food that had plenty of nutrients and vitamins. Nowadays, much of the modern diet consists of refined sugars, processed foods, additives and alcohol‚ in other words, NOT fresh and having very little or ABSOLUTELY ZERO nutritional value. These eating habits are major contributors to a weakened immune system.

I feel like you know this already but let me remind you that your body isn’t going to get the proper amount of vitamins, nutrients, antioxidants and minerals it needs simply by eating fruits and vegetables. While that’s certainly better than fast food hamburgers and trashy snack foods, much of our produce nowadays is lacking in sufficient antioxidants and nutrients too, sadly. This is due to constant overfarming and soil depletion‚ which takes out more nutrients than puts back. And don’t forget, most of our fruits and vegetables are NOT vine ripened. They are picked green, or prematurely, to accommodate the far away markets they travel to. To give the immune system the proper fuel and raw materials it needs to work properly you need a rather large dose of antioxidants and vitamins‚ which you’re getting if you are taking your OPC Factor regularly.

Other things like exercise and stress management are also important for healthy immune systems.

By the way, if you are taking your OPC Factor daily and you feel a cold coming on you may want to up your dose and take two in the morning and one at night. I take two packets in the morning for the sole reason of keeping my immune system in check. In fact, if you read the ingredients list on the back of a packet it reads just like a list a nutritionalist would give you for immune boosting supplements.

So, sleep well, eat well, don’t go nuts with the antibiotics (you don’t need them at all for viral infections‚ only bacterial ones) and take your OPC Factor for the antioxidants and free radical fighting ingredients as well as its white blood cell-boosting power.

I hope this series has inspired you to go the extra mile in taking care of yourself and giving your body what it requires to keep you healthy for a long, long time. Now if the immune system can find a way to fend off these darn squirrels who are eating all my wife’s bird seed I will really be impressed.

Good Question


You list Cruciferous vegetable concentrate on your box. What is this and what benefit does it add?


Broccoli, cauliflower, cabbage, mustard and collard greens, brussel sprouts‚ all cruciferous vegetables that are added to help protect your cells from oxidation.

Cruciferous vegetables(Brassicaceae), is another name for the mustard family‚ the yucky vegetables we didn’t want to eat when we were kids. We include these in OPC Factor because studies show that sulforaphane, found in broccoli sprouts and cabbage, is effective in protecting cells from oxidative stress. According to researchers sulforaphane may play a key role in increasing the body’s natural antioxidant defense systems. They may also function as a powerful indirect antioxidant with a much longer lasting effect than vitamins C and E alone provide. Cruciferous vegetables are also high in vitamin C, selenium, fiber and are thought to contain powerful anti-cancer properties.
