The human immune system contains various types of white blood cells, such as T cells and B cells, as well as antibodies and other molecules and structures that help the body recognize and respond to foreign invaders, such as bacteria and viruses. The immune system also includes the thymus, spleen, lymph nodes, and bone marrow, which play important roles in the production and function of white blood cells.

The immune system involves the complement system, a group of proteins that work together to enhance the ability of antibodies and white blood cells to fight invading organisms. Therefore if the immune system becomes defective it becomes important to take the help of a doctor who possibly would suggest some immune boosting supplements to strengthen your lost immunity. 

But what are immune boosting supplements?

Immune-boosting supplements are dietary supplements that are intended to support the function of the immune system. Some examples include:

  • Vitamin C: an antioxidant that helps the body produce white blood cells and is known for its role in supporting the immune system.
  • Vitamin D: a vitamin that helps the body produce white blood cells and is important for the function of the immune system.
  • Zinc: a mineral that plays a role in the production and function of white blood cells and is important for the immune system.
  • Echinacea: an herb that is sometimes taken to support the immune system and reduce the severity and duration of colds and other upper respiratory infections.
  • Elderberry: a berry extract that is often used to support the immune system, particularly during the cold and flu season.
  • Andrographis: an herb that is used to support the immune system and reduce symptoms of upper respiratory infections.
  • Garlic: a vegetable that is used to support the immune system and has antibacterial, antiviral, and antifungal properties, etc.

It's important to note that some of these supplements have not been proven to be effective and some of them can have side effects if taken in large doses or for prolonged periods. It's always a good idea to talk to your doctor before taking any supplements, especially if you have any health conditions or are taking any medications. Also, it is important to note that no supplements are meant to cure or prevent disease.
