The body as we know it is a complex living machine that works 24hr a day, 7 days a week, without ever taking a day off. Within this machine, there is a massive and complex structure of processes that guard the body against any threats that can possibly harm it. This is called the immune system

What is the immune system?

The immune system is a complex network of cells, tissues, organs, and systems that work in harmony to protect the body against invasions or attacks from harmful or foreign organisms. They achieve this by keeping them out of the body, destroying them totally once they are in the body system, and/or limiting their damage in the body.

You can read more about it on Medline Plus.

Being the body’s protector it is very important that we protect and strengthen the immune system at all times because every day, it is protecting us from falling ill. When the immune system is weak, it leads to poor health because then, every little organism can wreak havoc on your body because its defense is poor.

Those that have low immunity such as pregnant women easily fall sick. Though, such an organism can hardly affect a healthy normal individual.

Autoimmune diseases

When things go wrong in the immune system, it stops being able to effectively recognize threats when they appear hence it tends to attack healthy cells in the body by mistake this is when auto-immune diseases such as HIV aids, allergies, etc. develop in the body.

Symptoms of a weak immune system

A weak immune system is not easy to pinpoint without an accurate blood count blood test. This accurately shows your body’s condition. But before that, there are some obvious signs that your immune system is weak such as:

  • Constantly feeling tired

Herbs & Supplements For the immunity

Black seed supplement

This is one of my most recommended immune-supporting herbs. It really helps me when I begin to feel any signs or even a slight change in my health that indicates some kind of a sickness. It works very fast. In fact many atimes, in less than 48 hours I can feel a difference in my body.

Also known as black cumin, it is known to originate from the middle-east and some parts of Asia. Traces of it were found in the tombs of the Egyptian kings and queens. This shows that it an ancient herb and has been used for ages.

Black seed is a very strong and potent spice and remedy that has numerous health benefits that we continue to discover today.  Black seed is used for some other health conditions beyond just improving immunity such as; an appetite stimulant, digestive problems, asthma, colds, hemorrhoids, etc.

How to use:

  • If you have the powder, take a teaspoon once in the morning and another in the evening.
  • If it is in a capsule or tablet, use as directed on the product packaging.

*Remember not to take this herb on an empty stomach. It is quite powerful and it can harm you. Always take it after meals. Estimate about 30mins after eating meals.

Raw Garlic

Garlic is an everyday spice and food in our kitchen but it is also a very old super-healer. It has antibacterial, antimicrobial, and antiviral properties that make it very useful when trying to improve your body’s immunity.

How to take it

  • Take 3-4 pieces of fresh raw garlic, not the whole garlic bulb. Just 3-4 medium-sized pieces from the whole bulb.
  • Chop it into smaller pieces that make it easier to swallow
  • Let them rest for 10 minutes so that the Allicin will be activated
  • Chew or swallow them with water like capsules or tablets.
  • Take the garlic until a day after you notice improvements. Maximum of 7 days

*Do not take more than 4pcs of raw garlic in a day. I will recommend that you do not add it to your food because it makes it much less effective than taking it raw as a stand-alone.

Caution: Go easy on the garlic if you know that you are taking blood clotting medication because it is also a natural blood thinner. So be careful. Feel free to choose other options from the list in that case.

Vitamin c

Vitamin C is one of those must-haves that the doctor always prescribes when we have a cold. This is because it is known to boost the function and strengthen the immune system by helping it fight off diseases and infections.

You can get vitamin C from one of its most known sources citrus fruits i.e oranges, lemon, etc. spinach, moringa leaves, baobab fruit, roselle flowers, etc. If you prefer tablets, vitamin C supplements are very common and should not be hard to find.

Just beware of the concentration of the tablet you are taking is not more than the 500mg-1000mg (maximum)  recommended daily dose. Too much vitamin C at once in the body can cause some health problems such as diarrhea.

Vitamin D

Vitamin D is commonly known as the vitamin we get from being in the sun. It is most popularly known for its importance in bone health but there is more to it. It is important in regulating immune responses in the body so that the body does not over-react or under-react to infections and diseases.

Its deficiency in the body is linked to autoimmunity and increased infections in the body.

The sun is a free and easy source of vitamin D which is why it is surprising that as much as 1 in 10 people in the world are estimated to have vitamin D deficiency. There are many factors that can affect the absorption of sunlight by the body so that it can produce vitamin D by itself.

This includes, the amount of clothes you wear, sunscreen, time of the day and very importantly the color of your skin.

Nobody black or white is born with an abundance of Vitamin D that they don’t need it from the sun anymore.  So, remember that the sun is good for you in moderation.

Get some morning or evening sun and let your body produce the vitamin D it needs.

If sitting or staying in the sun is not possible for you, you can try the vitamin D supplements from the pharmacy and other health shops. Best of luck


Iron is one of those supplements that many of us forget but it is very important for proper body function. All cells in the body need iron for immunity. It is needed to transport oxygen to the white blood cells which are one of the pillars of the immune system.

Without them, the immunity is weakened and iron also prevents anemia which is also another health condition that weakens the body.

You can get iron from fish, seeds, spinach, moringa leaves, red meat, seafood, etc. You can also get a good iron supplement that can help you while you try to catch up with a proper diet. We cannot take supplements forever.

You can learn more on iron in the body from the active iron website.


Zinc is needed for the production and development of new immune system cells in the body. It also reduces the risk, severity, and period of infections.

The popular lozenges that we suck on when we have colds contain zinc for a boost in the immunity.

Some research shows that zinc deficiency might cause immune dysfunction.

Zinc in our diet lies in seafood, fish, beans, yogurt, etc. You can decide to take supplements for immediate improvement as the concentration of minerals and vitamins in foods are less than in tablets


Ginseng is among the most internationally known herbs in the world. It became very expensive and difficult to get once people realized its benefits. It is used for anti-aging, immunity, energy, etc.

Though this herb is not commonly available, there are tonics, sweets, drinks that are made from it that can be used to improve immunity.

Caution should be taken though as many ginseng products contain a small percentage of the actual ginseng herb due to its high price. Try and check the percentage of the ginseng herb in the product before buying it.

Are these remedies safe during pregnancy?

The remedies mentioned are safe for pregnant women. Most of the mentioned remedies are either food items we eat or vitamins that we need not just for immunity but for everyday body function.

Care should be taken when buying any of these supplements. Make sure that you have checked the product to be sure that the particular supplement is safe during pregnancy.

4 important Habits to Boost your Immunity

Apart from remedies, we can take orally to help our immune system, there are some very important things in our lifestyle that unless we get them right, no remedy or herb can help you. This is because these activities are very important to the body’s health and function. These include:


Manage your stress levels as much as you can. Studies have shown that when a person is stressed or under duress, the body’s immunity becomes weaker.

If you remember at the beginning of the Covid-19 pandemic, some doctors advised the public to not panic because, during these challenging times, we need to strengthen our immunity not weaken it with stress.

We should not make ourselves sick before we get sick.


Quality sleep is a very important factor in being healthy and to some extent, alive. Without good quality sleep, our bodies become too tired to function and when sleep-deprived, may shut down.

Try and maintain healthy sleeping patterns to protect yourself from diseases. Studies have shown that our body produces proteins in the body to fight infections as we sleep hence, inadequate sleep lowers our immunity.

Diet and Exercise

Diet and exercise are mentioned very often in areas related to improving and maintaining one’s health. This is because the body is designed to be most healthy when we are active in our life.

Being active and exercising well by jogging, walking, biking, swimming, etc. protects our hearts, helps in balancing our hormones, weight, and keeps away many other diseases. 

Let us not forget that we are what we eat so, if we have a poor diet, our body functions, systems, and overall health will also be poor.  Proteins are particularly important and are needed by the immune system to protect itself.

When you need an immediate immunity boost such as when you are starting to feel sick, here are the remedies that I will recommend. Their effect is almost immediate and I have had personal from experience using them. They really work fast.

They are the blackseed supplement/powder, the garlic, and the vitamin C. You can take these all three within 24 hours spacing them at 4-5 hours intervals. or, you can simply select one and use them alone. It’s up to you. They are safe and highly effective. Couple these 3 remedies with the good habits outlined above, you will feel fine in no time.

Just a reminder, it is not to say that the other recommended remedies are not effective. It will simply take 5-10 days before you notice significant improvement and some of us need an immediate solution.


Those with strong immunity are known to maintain a healthy lifestyle of good diet, daily habits, exercising or having an active life, etc. A combination of these factors helps in protecting them from contracting diseases.

There are some health conditions that contribute to a weak or low immunity which is why it is important to continue to improve your body’s immunity all the time.

I hope these recommendations will work for you because these are actually the herbs and supplements that I use when I start feeling a little off.

Many of these are simple herbs and supplements that we use regularly and you can easily get them in most places around the world.
