Best Supplements For Boosting Immune System

best supplements for boosting immune system

You can boost your immune system by consuming a variety of food and supplements. Among the foods that you should consider include green tea, Zinc, Vitamin D, and Probiotics. These nutrients are important for the immune system, so eating them regularly will help you avoid the onset of illnesses.


Zinc supplements are important for boosting the immune system. They have been shown to increase mRNA production of several types of immune cells. This mineral is found throughout the body and plays a crucial role in many functions, including the repair of DNA, wound healing, and immune cell growth.

The immune system is highly dependent on zinc. Zinc deficiency is correlated with decreased immune function. Aging and certain illnesses may contribute to a decreased zinc level in the body, but supplementation may help improve immune function in the elderly. Several studies have shown that taking zinc supplements may increase the immune system’s capacity to fight off viruses.

The trace element zinc is essential for the growth and development of all organisms. In particular, the high rate of differentiation and proliferation of cells in the body requires a steady supply of zinc. Different forms of zinc play different roles in the immune system.

Vitamin D

Researchers have discovered that taking vitamin D supplements can increase the immune system’s ability to fight infections. Vitamin D helps the body activate T cells, which recognize and destroy foreign pathogens. This vitamin is essential for the immune system’s normal functioning. However, some studies show that it may not be as effective as doctors and scientists originally thought.

Many people have low levels of vitamin D, which can lead to infections. Those with low vitamin D levels are at higher risk for upper respiratory tract infections, such as the flu. One study found that supplementation with vitamin D reduced the risk of influenza and upper respiratory tract infections by 42%.

Green tea

Green tea is an excellent immune system boost. It contains polyphenols, which are noteworthy antioxidants. In addition, it is great for your digestion. It offers a three-fold protection from illness when consumed regularly. Moreover, it is free from calories and is highly digestible. Therefore, you can drink a cup of green tea at any time, without the need to worry about side effects.

Various studies have proven that green tea can help you fight flu. In fact, the polyphenol EGCG binds to the glycoprotein of the flu virus, preventing it from infecting other cells. It also inhibits the neuraminidase enzyme, which can slow the spread of many viruses. It also contains L-theanine, which has been shown to stimulate the immune response. Specifically, L-theanine activates gamma-delta T lymphocytes, which are fast acting immune cells.


The human immune system is a complex network of organs, tissues, and proteins that work together to protect the body from pathogens, toxins, and stress. Probiotics play an important role in immune health. They are found in the human gut, which is a busy place filled with bacteria.

Research has shown that probiotics promote the immune system and may reduce the risk of respiratory illness. In addition, they may enhance the surface of dendritic cells and help the body fight off viruses. Several strains of probiotics have been proven to boost the immune system, including L. acidophilus and Bifidobacterium.

Probiotics come in many forms, with some being more beneficial than others. The most popular strains for immune support are from the Lactobacillus acidophilus family. These strains produce acids that prevent pathogen growth. Some of them also manufacture vitamins and short-chain fatty acids. Bifidobacterium lactis has also established a good reputation as an immune enhancer.


Elderberry supplements boost the immune system and are an excellent way to protect yourself from the flu and colds. There are many different types of elderberry supplements. However, you should consult with a healthcare provider before taking elderberry supplements. If you’re pregnant, nursing, or have severe allergies, you should avoid taking elderberry supplements. Also, you should consult with your doctor if you’re taking any medication.

Elderberry has a long history of use in traditional medicine. Although the fruit can cause mild side effects, research suggests it’s safe and effective at combating respiratory ailments. Most studies involving elderberry have been conducted using doses of around 600 mg a day. However, a study published in 2016 found that taking 900mg daily resulted in quicker recovery times and fewer cold-related symptoms. There are various elderberry supplements on the market, but capsules are the most effective. They contain a guaranteed minimum dose of flavonoids. In addition, they often contain vitamin c and zinc.
