immunity boosting supplements

In today's world, many people are looking for ways to keep their immune systems strong. Should you be taking immunity-boosting supplements?

With COVID-19 and the usual cold and flu seasons, having a strong immune system is more important now than ever.

This is why many people are considering immunity-boosting supplements.

These supplements can help you achieve that goal and stay healthy for years to come — if you choose the right ones.

Unfortunately, like any other supplement, there's a lot of ineffective and downright useless products out there.

Knowing which immunity-boosting supplements are best, and how to incorporate them into your daily routine, is an excellent way to ward off viruses and other illnesses naturally.

Doing so enhances your body's exceptional ability to heal itself.

Let's dig deeper into immunity-boosting supplements and figure out which ones are right for YOU.

Make your health a priority — and boost your immune system — with these easy lifestyle changes.

The Immune Booster Guys 40+ Are Using To Kill Viruses & Feel Younger…

As men age, our immune systems get weaker.
It’s a fact. After 40, you become more vulnerable to viruses, cancers, and even Alzheimer’s disease. Average guys just let this all happen. But now, with Immune Booster RX, you can take the power back.

How to Choose Safe Supplements

Supplements aren't as tightly regulated by the U.S. Food and Drug Administration (FDA) as foods and medicines, which is why choosing top-quality dietary supplements from a reputable manufacturer is important.

Such supplements, including the Fit Father Project's Immune Booster RX immunity-boosting supplement, are third party tested for quality, safety, and purity.

When choosing Fit Father Project products, you have peace of mind knowing the ingredients listed on the supplement facts label are truly what you're putting into your body.

Types of Immunity Boosting Supplements

Immunity boosting supplements often contain vitamins, minerals, herbs, or combinations of these ingredients. Examples include:

Vitamin and Mineral Supplements

Vitamin C

Vitamin C is an essential water-soluble vitamin with immune-boosting powers, abundant in fruits and vegetables.

Studies show that vitamin C deficiency can impair immunity, making you more susceptible to infections.

Vitamin C supplements may prevent bacterial, viral, and other infections by shortening the duration of colds and acting as a natural anti-inflammatory and antihistamine.

Foods rich in vitamin C include:

  • Red bell peppers
  • Orange juice
  • Oranges
  • Grapefruit juice
  • Kiwi fruit
  • Green bell peppers
  • Broccoli
  • Strawberries
  • Brussels sprouts
  • Grapefruit
  • Tomato juice
  • Cantaloupe
  • Cabbage
  • Cauliflower
  • Potatoes
  • Tomatoes
  • Spinach
  • Green peas

The recommended dietary allowance (RDA) for men is 90 milligrams of vitamin C per day.

Make sure your multivitamin supplement contains vitamin C, or consider an immunity-boosting supplement for men with vitamin C as an ingredient.

Vitamin D3

Vitamin D3 is a form of vitamin D containing powerful immune-boosting activity that protects you against colds, flu, and other illnesses when taken regularly.

Studies show vitamin D enhances immune function by regulating specific immune cells.

Foods rich in vitamin D include:

  • Cod liver oil
  • Trout
  • Salmon
  • Sardines
  • Mushrooms
  • Milk
  • Plant milk
  • Yogurt
  • Eggs
  • Ready-to-eat cereal

Men need at least 15-20 micrograms of vitamin D daily to achieve optimal health and strong immunity.

How much Vitamin D3 is too much? This video has the answer!

Vitamin A

Taking an immune-boosting supplement containing vitamin A can enhance your body's ability to fight infections, particularly respiratory infections.

Studies show that vitamin A has anti-inflammatory properties and optimizes your body's immune-boosting powers.

Foods rich in vitamin A include:

  • Beef liver
  • Sweet potatoes
  • Spinach
  • Pumpkin
  • Carrots
  • Milk
  • Cheese
  • Yogurt
  • Fish
  • Cantaloupe
  • Red peppers
  • Mangoes
  • Eggs
  • Fortified breakfast cereals
  • Apricots
  • Broccoli
  • Tomato juice

The RDA for vitamin A is 900 micrograms per day for men.

Eat a variety of vitamin A-rich foods daily and take a multivitamin or immunity-boosting supplement containing vitamin A.

Vitamin B6

Vitamin B6 is an essential nutrient important for proper brain, nervous system, and immune system functioning.

Getting too little vitamin B6 increases your risk of confusion, depression, and a weak immune system — which boosts your chance of getting sick.

Foods rich in vitamin B6 include:

  • Chickpeas
  • Other legumes
  • Winter squash
  • Beef liver
  • Fish
  • Chicken
  • Turkey
  • Beef
  • Fortified breakfast cereals
  • Potatoes
  • Bananas
  • Bulgar
  • Cottage cheese

The vitamin B6 RDA for men is 1.3-1.7 milligrams daily.

Make sure your multivitamin or immunity-boosting supplement contains B vitamins, and eat vitamin B6-rich foods regularly.


Zinc is an essential mineral your body needs on a regular basis to function properly.

Numerous studies confirm the role zinc plays in optimal immune health, which is why this micronutrient is present in numerous immunity-boosting supplements.

Foods rich in zinc include:

  • Oysters
  • Beef
  • Chicken
  • Pork
  • Crab
  • Lobster
  • Baked beans
  • Kidney beans
  • Peas
  • Other legumes
  • Fortified breakfast cereals
  • Oatmeal
  • Nuts
  • Seeds
  • Milk
  • Yogurt
  • Cheese

The zinc RDA, which is the minimum daily requirement, for men is 11 milligrams of zinc per day.

This video will teach you what vitamins are, what each does for your body, and what foodstuff you can get these vitamins from.

Herbal Immunity Boosting Supplements


Echinacea is an herb widely available in immunity-boosting supplements.

If you take it when you're well, it may reduce your risk of getting sick from colds, flu, and other illnesses.

Make echinacea part of your daily routine to keep you healthy with minimal to no risk of side effects.


Like echinacea, elderberry is an herbal supplement used to strengthen your immune system and reduce your risk of getting sick.

Studies show that taking elderberry supplements helped study subjects shorten the duration of colds and reduce cold symptoms.

As with many other herbs, elderberry is a natural immunity boosting supplement.


An immunity-boosting dietary supplement called astragalus is often present in combinations with other herbs to reduce the severity of or protect against certain illnesses.

Examples include hay fever, respiratory infections, chronic fatigue, asthma, and more.

This type of immunity-boosting supplement appears to strengthen and better regulate your immune system.

It may also speed up wound healing and improve blood flow when used topically.


Beta-glucans are natural sugars found in cell walls of bacteria, yeasts, fungi, algae, oats, barley, lichens, and other plants.

Studies show that beta-glucans play a role in various immune system responses and even some cancer treatments.

A beta-glucan supplement might reduce your risk of high cholesterol and heart disease if you take it regularly.


L-theanine is a compound found naturally in green and black teas.

It's available in supplement form and appears to offer a wide array of health and wellness benefits.

Examples include better mental focus, improved sleep quality, healthy weight management, better immune functioning, and reduced stress and blood pressure.

Adaptogenic Mushroom Blends

Believe it or not, mushrooms also play a role in maintaining a healthy immune system.

Studies show that various types of mushroom blends in supplements appear to optimize immune function and protect you against certain types of cancer.

Consider adding supplements containing mushroom blends to your daily regimen to enhance wellness, or look for immunity boosting supplements for men with adaptogenic mushrooms as ingredients.

Always check in with your doctor before trying a new dietary supplement.

Additional Ways to Boost Immunity

In addition to taking immunity-boosting supplements for men, there are several other steps you can take to strengthen your immune system and reduce your risk of getting sick.

Maintain a Healthy Weight

Achieving and maintaining a healthy weight is one of the best ways to optimize your body's immune system functions.

Try to keep your body mass index (BMI) between 18.5 and 24.9 by eating right and getting plenty of regular exercise most days of each week.

Calculate your BMI by multiplying your body weight in pounds by 703, dividing that number by your height in inches, and dividing by your height in inches again.

Sign up for the Fit Father Project's 30X (FF30X) program to increase your chance of effective weight loss.

You'll receive custom meal plans, fat-burning workouts, health coaching support, weekly newsletters, recipes, and much more!

Exercise Regularly

Participate in regular exercise to give your immune system a boost, but don't overdo it.

Make sure to rest properly in between training sessions.

Aim to get at least 30 minutes of aerobic and/or strength training exercise on most days of the week.

Try Fit Father Project workouts at the gym or from the comfort of your home!

Eat Immune-Boosting Foods

A healthy diet contains immune-boosting foods rich in antioxidants, protein, fiber, probiotics, or healthy fats.

Examples include fruits, vegetables, yogurt, kefir, chicken, fish, whole grains, legumes, nuts, seeds, plant oils, avocados, and other healthy fats.

Aim to fill half of your plate with non-starchy vegetables and the other half with protein-rich foods and fiber-rich starches.

Add calcium-rich dairy foods or dairy alternatives, fruits, and healthy fats to your meal plan and drink plenty of water.

Get Plenty of Sleep

Getting plenty of sleep is one of the best ways to keep your immune system strong.

Aim to get at least 7-9 hours of sleep at night whenever possible.

Head to bed at the same time each night, develop a consistent bedtime routine, and avoid caffeine and alcohol before going to sleep.

Don't head to bed hungry or too full. Have a small snack, such as a whey or casein protein shake, before you turn in for the night.

Sleep in a cool, dark, quiet room and try a white noise machine to block out loud sounds if you're a light sleeper.

These 7 ways to sleep better will improve your sleeping habits, helping you to wake up rested in the morning.

Properly Manage Stress

Stress can affect your hormone levels, appetite, diet, emotions, and sleep quality.

Chronic stress can also weaken your immune system.

Stress-reducing strategies that can enhance relaxation include spending time with loved ones, getting regular exercise, being outdoors, taking a vacation, getting a massage, or participating in yoga, meditation, or tai chi.

Getting in touch with your spirituality can help too!

Don't Smoke

Smoking can weaken your body's immune responses, making it difficult to fight off illnesses and diseases.

In fact, smoking increases your risk of heart disease, stroke, cancer, lung disease, diabetes, emphysema, chronic bronchitis, and chronic obstructive pulmonary disease (COPD).

It boosts your chance of experiencing tuberculosis, rheumatoid arthritis, and certain eye diseases.

If you're unable to stop smoking on your own, see a doctor about smoking cessation classes, counseling, medications, or other medical treatments to help you effectively quit long term.

Avoid Excessive Alcohol

If you can avoid alcohol entirely to keep your immune system strong, go for it.

When choosing to drink alcohol, do so in moderation.

That means don't consume more than two alcoholic drinks per day for men and one drink daily for women.

Alcohol not only can weaken your body's immune system, but it also increases your risk of developing a certain type of cancer.

Moderation is key, and don't feel embarrassed to give up alcohol entirely if you can and want to!

Practice Good Hygiene Habits

While having a strong immune system is the best way to ward off illnesses or reduce their severity, practice good hygiene habits to further reduce your risk of infection.

Wash your hands often, use hand sanitizer after shaking hands or touching shared surfaces, don't share utensils, and socially distance from people who are sick.

In this video, we reveal why life balance is the TRUE KEY to staying healthy.

Keeping Your Immune System Strong

Keeping your immune system strong is the best way to stay healthy, avoid costly medical bills, and reduce the need to take medications for illnesses and diseases.

It often allows you to take fewer sick days off from work, stay energized, and maintain a high quality of living.

Adopt healthy lifestyle habits that include nutritious eating, getting regular exercise and plenty of sleep, maintaining a healthy weight, reducing stress, and steering clear of tobacco products and alcohol when possible.
