It comes as no surprise that having a weak immune system is one of the top reasons for falling sick. People with a weak immune system are more prone to severe infections and viruses including COVID-19. [1] This is because the immune system is your body’s line of defence. It is made up of antibodies, white blood cells, lymph nodes, organs and other components. Together, these components fight to keep you healthy.

However, many births and environmental factors like malnutrition, HIV, viral hepatitis, cancers and even medication can weaken the immune system. This leaves you open to infection, but you can always build your immunity back up, provided you address the cause in time. To know all about symptoms of weak immunity and the supplements to boost the immune system, read on.

What are the symptoms of a weak immune system?

Recurring Infections

One of the common symptoms of a weak immune system are frequent infections. These may include more than four ear infections in a year, pneumonia twice a year, or chronic sinusitis. [2]

High-level stress

A study reported that long-term stress affects your immune system negatively. [3] It lowers your lymphocyte levels, the white blood cells that help your body fight infections. With high levels of stress, your chances of developing the common cold and other complications are much higher.

Frequent cold

It’s normal for you to catch a cold two to three times a year. [4] The normal cold is usually cured in 7 to 10 days. However, if you find yourself getting a cold constantly or having it longer than usual, your immune system may be too weak to help you recover completely.

Fatigue and tiredness

If you experience fatigue or tiredness all the time, it could mean that you have a weak immune system. If you have a body and joint pain even after getting the required sleep, it may indicate that your body’s defense system is struggling. Lower immunity decreases your energy levels.

Digestive issues

Your digestive tract holds almost 70% of your immune system [5]. This is because all the helpful bacteria and microorganisms that protect your gut from infections are found in this region. Common issues like constipation, gas, or frequent diarrhoea are all symptoms of weak immunity.

Slow wound healing

Healthy immune cells play a major role in healing skin cuts, burns, and wounds. Your body sends nutrient-rich blood to the affected area that helps regenerate new skin. However, if you have a weak immune system, your body struggles and fails to regenerate. This increased time to heal is a clear sign of weakened immunity.

Supplements to boost the immune system

Here is the list of some vitamins and supplements to boost the immune system. However, it is better to consult your nutritionist before consuming these to ensure they suit your unique requirements.

· Vitamin C

Vitamin C prevents infections but the body doesn’t produce it naturally. You get it from citrus fruits such as oranges, strawberries, and other foods.

· Vitamin B6

This vitamin supports biochemical reactions in the immune system. It is naturally found in white meat, green vegetables, and fish such as salmon and tuna.

· Vitamin D

Sunshine is the best natural source of vitamin D. You can also consume fish, milk, fruit juices, and cereals for this vitamin.

· Vitamin E

This antioxidant helps keep infection in check. You can consume seeds, spinach, and nuts to get in the required amounts.

· Folate/Folic acid

Folate or folic acid is another rich source with health benefits. Get it from beans, lentils, and green vegetables.

· Iron

Iron helps your body carry oxygen to cells and strengthens your immune system. You can find it in red meat, white meat, and vegetables too.

· Zinc

Zinc is mostly found in meat. It helps in the production of new immune system cells.
