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.

Recommended Dosage

Take 1 capsule daily, preferably with water or your favorite beverage.

Best Time to Take

For optimal results, consume the supplement in the morning on an empty stomach or as advised by your healthcare professional.

Consistency is Key

Incorporate the supplement into your daily routine to help maximize its benefits.

Reviews for Immune System Support

A combined formula or individual nutrients?

Immune System Support brings vitamins, minerals, botanical extracts and mushroom ingredients together. Compare it with the separate Vitamin C and Chelated Zinc options. Check ingredient overlap rather than assuming that more products are necessarily useful.

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.
