Best Vitamins to Support Immune System

best vitamins to support immune system

When looking for the best vitamins to support immune system, vitamin C is the number one option. This essential vitamin supports leukocytes, or white blood cells, which fight infections. Foods high in vitamin C include oranges, strawberries, tomatoes, cranberries, and orange juice. Mushrooms and vitamin D are also good choices for boosting the immune system. However, it is important to understand that these foods are not immune-boosting on their own.

All-natural options

The immune system functions well when it is filled with healthy micronutrients from colorful fruits and vegetables. Iron, selenium, zinc, and several B vitamins are needed for proper immune system function. A lack of these nutrients can weaken the immune system and impair other vital functions. If you suffer from a cold, consider eating plenty of fresh fruit and vegetables. These foods are packed with antioxidants that boost the immune system.

Supplements with antiviral properties

Many popular dietary supplements and foods contain ingredients with antiviral properties. These products can support your immune system, but it is important to note that some dietary supplements have not been evaluated by the FDA before they are sold. Before you begin a supplementation program, discuss your options with your healthcare provider. The best supplements will contain ingredients that are not only high-quality but also have been tested independently. Listed below are some common types of dietary supplements with antiviral properties.

Mushrooms boost immunity

Adding mushrooms to your diet can be an excellent way to strengthen your immune system. They contain powerful antioxidants and can improve your overall health. You can also add mushrooms to your salads, soups, and pasta dishes. These fungi are the unsung heroes of a healthy diet. Eating more mushrooms can even slow down the aging process. These superfoods have been used to fight off disease and slow down the aging process for thousands of years.

Vitamin D

It is well-known that Vitamin D helps strengthen our immune system. It has several functions, including regulating immune cell activity and producing antiviral peptides called cathelicidins and defensins. These peptides are part of our innate immune response and play a crucial role in protecting us from infection. Vitamin D metabolites also boost the activity of human cathelicidins.


Zinc is a trace mineral that plays a crucial role in the immune system, boosting the body’s ability to fight infection. It is necessary for the development of antibodies and plays a key role in the production of natural T-killer cells, which are crucial in the fight against viruses and bacteria. It is also an antioxidant that aids in the reduction of inflammation within cell membranes.

Astragalus root

Astragalus is a perennial plant native to Korea, northern China, and eastern Mongolia. It is also used for its medicinal benefits. It is highly nutritious, with many nutrients and vitamins that support the immune system. This plant is said to prevent and treat various diseases, including respiratory infections. While more studies on its effectiveness are needed, it has proven to be successful in animal studies. Astragalus is an adaptogen, meaning it helps the body adapt to stress and toxins.
