The Immune System: Components, Functions & Recommended Supplements

Why Is The Immune System Important?

The immune system is a very complex and fascinating area of the body. It comprises many parts of the body, including the thymus, spleen, lymph system, bone marrow, white blood cells, antibodies and hormones. This massive system is responsible for making the rest of your body feel well. In turn, every organ and system in the body must work together to keep the immune system in peak condition.

Maintaining Immune Health

While many internal factors contribute to immune wellness, it's the outside factors that act as the building blocks of a healthy immune system. Good hygiene, getting enough sleep, drinking water, exercising, eating well, and taking natural supplements all contribute to a healthy immune system. We may not be able to help with most of those, but we can help you find the right supplements to take to support your good health.
