Background
There are many factors that can challenge a healthy immune system including stress, exposure to toxic compounds, allergies, bacteria, viruses, irregular sleeping patterns and poor diet. The immune system is highly complex and comprised of specialized immune cells, each playing a vital role in maintaining and regulating normal, healthy immune function.

Immune Support is a comprehensive formula providing essential vitamins and minerals for general nutritional support, along with a generous supply of specialty agents specifically associated with immune wellness. The synergistic combination of ingredients helps create an ideal environment for optimal immune function.

Echinacea Immune Activation

Echinacea helps activate the immune system and stimulate specific immune cells that are critical to maintaining overall health. It also helps support respiratory health, particularly during seasonal challenges such as the winter months.

Medicinal Mushroom Support

Maitake, Shiitake and Reishi mushrooms contain polysaccharide compounds that help stimulate important immune cells and support overall immune function.

L-OptiZinc® Immune Support

L-OptiZinc® is a patented form of the essential trace mineral zinc, required for proper growth and function of many types of immune cells. It also supports the health of the thymus gland, where immune cells known as T-cells are produced.

Quercetin Antioxidant Support

Quercetin is a powerful antioxidant that helps support healthy histamine levels, which play a role in cold and allergy-related symptoms.

Goldenseal & Garlic Support

Goldenseal contains the immunostimulatory compound berberine, while garlic provides sulfur-containing compounds that offer additional immune support.

Traditional Herbal Support

Ligustrum has been traditionally used in Chinese medicine to support a healthy immune system.

Reviews for Immune System Support

Immune Support combines essential vitamins (A, C, B-complex), L-OptiZinc®, European standardized herbs (Echinacea, Astragalus), and premium mushroom extracts (Maitake, Shiitake, Reishi) to address immune health from multiple angles—something most formulas don't offer.

Take daily for best results! This formula is designed for ongoing immune support to help maintain healthy immune function year-round, especially during cold/flu season or times of stress, rather than just acute illness.

Our premium Maitake (TD fraction), Shiitake, and Reishi mushroom extracts provide powerful immune-modulating compounds not found in other immune formulas. These mushrooms have been used for centuries in traditional medicine for immune support.

L-OptiZinc® is the most clinically studied form of zinc and the only patented methionine-bound zinc, providing superior absorption and bioavailability compared to regular zinc supplements for maximum immune support.
