PREMIUM IMMUNE PRODUCTS

Recent independent laboratory studies show that our products bolster Natural Killer (NK) cell activity in the presence of a health threat, while activating a variety of other immune system cells, such as: B cells, T cells, and macrophages.† 

NK Cell

NK Cells (Natural Killer Cells) do exactly what their name suggests. They detect and destroy harmful invaders. NK Cells have the uncanny ability to identify health threats with little to no information. They are the special forces of your immune system.  

T Cell

T cells mature in the thymus gland. They help your body distinguish between friend and foe. They work with NK cells to attack harmful invaders. 

B Cell

B cells are born in the bone marrow, which is the tissue inside your bones. When activated, they assist in antibody production and immune system memory. 

Macrophage

Macrophage is Greek for “cell eater”. Macrophages locate and eat dead cells and cell debris. They also consume microbes, including bacteria, parasites, viruses, and fungi.  

NOURISH. EDUCATE.
ENHANCE. BALANCE.

Natural, power-packed products await!
