Natural killer cells are part of our first-line defense response. NAC (n-acetyl-l-cysteine) promotes glutathione production for antioxidant protection and provides lung defense mechanisms for healthy respiratory function. In a randomized double-blind trial involving mostly older individuals, NAC showed support for respiratory health. Quercetin and elderberry provide flavonoids that offer additional support for immune and respiratory function while vitamin C, vitamin D and zinc play important roles in immune cell activation. 

This convenient packaging is designed for travel and short term use.

T helper type 1 (Th1) cells are part of our  CD4+ effector T cell line that is required for host defense against  viral and bacterial pathogens. This formula contains a blend of berberine, baicalin from Chinese skullcap, sulforaphane from broccoli, ginger, and zinc and each ingredient has a specific effect on the Th1 cell, promoting natural defense. 

​

Th1 responses are affected by stress, aging, and cytokine changes resulting from metabolic, hormonal, physiological, and environmental factors.

Quercetin is a bioflavonoid that supports healthy immune function and inhibits oxidative stress and the inflammatory response. This formulation provides quercetin encased in plant-derived phytosome delivery system.  In a randomized clinical study, researchers compared two orally administered quercetin phytosome doses (providing 100 mg and 200 mg of quercetin), along with one 500 mg dosage of traditional quercetin. They found that the quercetin phytosome could be administered at one-fifth the dosage of the traditional quercetin and still result in exposure 10 times greater. This means that the quercetin phytosome provides about 50 times greater bioavailability than traditional quercetin, which is important because quercetin is poorly absorbed.

Quercetin can also inhibit histamines in the body and protect against tissue injury caused by toxins. It has been shown to bind to virus specific proteases and inhibit replication. 

This formula affects NK (natural killer) cells and macrophages, the cells that act as defense alongwith IgA and IgG levels in the bloodstream. These antibodies play a key role in mucosal immunedefense. The special blend of astragalus, reishi mushroom beta glucans and lectins derived from reishi mushroom,  support macrophages and cytokine balance.  Inflammation is part of our natural immune response, but can easily get out of control. Innate Immune Support contains active ingredients for healthy immune balance and function. It is recommended to take 1-2 capsules daily, especially during times of stress, travel or frequent illness.
