Your body's immune system is the natural, front line defense to protect you against harmful pathogens and infections. You can boost the effectiveness of your immune system through diet and exercise, but did you know that certain vitamin subscriptions and supplements can aid your immune system and promote general wellness? You can even take certain probiotics to help boost your immune system. Here are our recommendations of the top supplements to help boost your immune system.


What is the Immune System?

There are two main aspects to the immune system: the innate and the adaptive immune system. The innate immune system is one you are born with, and it is the body's rapid response system. It works to attack antigens or invaders in the body. The adaptive or acquired immune system builds antibodies to protect your body from certain microbes, or germs, it encounters in the environment.

Did you know that your immune system keeps track of each germ it has ever defeated? This way, if your body encounters a germ it has fought in its immune system before, it can recognize and protect your body from it more effectively.

Your immune system's memory of the germs it encounters is stored in white blood cells. The white blood cells move through the blood and tissue in your body and attack harmful invaders such as viruses and bacteria.

Fortunately, you can support and improve the effectiveness of your immune system by maintaining a healthy diet, exercising regularly, drinking alcohol in moderation, and getting a proper amount of sleep. Taking melatonin can help you get better sleep, which will in turn support immune health.

Your skin also plays a role in your immune system, and you can take certain vitamins and supplements for dry skin to help it stay hydrated and healthy. Additionally, the microbiome found in your digestive system is important to proper immune function. Probiotics and digestive enzymes can both help improve your digestion and boost your immune system.

Vitamins and Minerals that Support the Immune System

It's no secret that certain vitamins and supplements can aid your immune system to fight off potentially harmful infections. Here are some that stand out.

  • Elderberry: There are around 30 different types of elder plants and trees globally. Sambucus nigra is the type that helps with healing and immune health. Elderberry consists of many vitamins and antioxidants.
  • Vitamin C: Your body doesn't naturally produce Vitamin C. However, it has proven to have immense health benefits. Vitamin C helps the immune system's white blood cell production.
  • Zinc: This supplement helps produce new immune system cells in your body.
  • Vitamin D: Vitamin D helps to regulate the body's immune system.
  • Vitamin E: This antioxidant is fat-soluble and helps protect cells from harmful 'free radicals' which are unstable atoms that can cause damage to cells; this response can lead to illness.
  • Reishi mushrooms: There are three molecules in reishi mushrooms that are responsible for their health effects: triterpenoids, polysaccharides, and peptidoglycans. Studies have found that reishi mushrooms may be able to change the inflammation pathways in white blood cells.

How to Choose an Immune Supplement or Multivitamin

There are a few key aspects to look out for when shopping for immune supplements. Below is a list of what to look for when shopping for a supplement to help boost your immune system.

What to Look For

When comparing different brands of immune supplements, look for these things before you buy.

Clinical Research: Many immune supplements will inform you if they're clinically researched formulas, or formulated by doctors.

Transparency: Some supplement brands list all of the vitamins and minerals they use in the formula of their supplement. It's important to know exactly what you're ingesting, and where it came from.

Lab Testing: To guarantee what you're consuming is pure, and safe, look too see if a brand had their product tested at a third-party lab.

Non-Artificial Ingredients: Immune supplements with natural, non-artificial ingredients that are plant-derived or organic are always a good choice. If the brand uses animal products, check to see that they are sourced ethically and sustainably.

How to Read Labels

When reading the label of your supplement, be sure to notice the serving size. Oftentimes, the recommended serving size for a supplement is larger than simply taking one capsule or multivitamin. Some labels will specify the best time of day to take the supplement as well. Also take note of the ingredient list, and how much of the recommended daily intake it fulfills for certain vitamins and nutrients

It's also important to double check that the supplement was tested in a third-party lab for safety and quality. Note if the supplement is non-GMO, vegan, or gluten free. Many supplements will also tell you if it is free from certain allergens like soy and dairy.

Safety & Side Effects

Ingesting the right oral immune boosting supplements may be beneficial to your overall health. However, there are a few minor side effects to be aware of. Some common side effects of immune boosting supplements may include:

  • Constipation
  • Headache
  • Cough
  • Nausea
  • Intense abdominal pain

Other, infrequent side effects may include:

  • Backache
  • Pain in arms or legs
  • Chest pain
  • Vomiting
  • Abdominal bloating

Sometimes, when certain vitamins are ingested without food can cause stomach pain. Be sure to read the label to see if you should take an immune supplement with food and to be sure that you do not take more than the recommended amount. Most side effects from vitamin supplements are a result of taking too much at one time.

Certain vitamin and mineral supplements can interact with prescription medications. If you take prescription medicines, or are undergoing prescribed treatment for a condition, consult with your doctor before taking any additional supplements.
