Immune & Lymphatic

Defense network

How does the immune & Lymphatic work?

Skin and mucus barriers, white blood cells, lymph nodes, the spleen and antibodies working together to recognize and clear threats.

Two layers

Innate immunity reacts fast and broadly; adaptive immunity learns specific invaders and remembers them.

Myth check

No single food or supplement 'boosts' immunity in healthy, well-nourished people. Deficiencies (e.g. of zinc, vitamin A, vitamin D) can impair it.
