What exactly goes into the Optimal Immune formula?
Primal Herb has chosen each fungi and herbal extract for its proven effectiveness, safety, research, and historical use.

Chaga (Inonotus Obliquus) Extract: 30% Polysaccharides
This medicinal mushroom, hailing from the boreal forests of the Northern Hemisphere, is chosen for this blend – particularly due to its immunomodulating properties, High beta-glucan and Polysaccharide content. It’s well-documented in studies that it may support both underactive immunity and autoimmunity, helping to support a Balanced Immune System.

Cracked Shell Reishi Spores
You could easily call this worldly mushroom the King of all Immune-Boosting Mushrooms. The most thoroughly studied for its Adaptogenic and Immune-Modulating qualities, it contains both Beta-Glucans and Polysaccharides that help modulate low immunity and autoimmunity.

Turkey Tail (Coriolus Versicolor) Extract: 30% Polysaccharides
A pretty multicolored mushroom reminiscent of a turkey, its health benefits are definitely nothing to gobble at. Its traditional uses for fighting colds and illness are translated today into research-supported immune powers: enhancing and balancing the immune system, combating viruses, restoring energy, and banishing fatigue in the face of immune issues.

Maitake (Grifola Frandosa) Extract: 30% Polysaccharides
Ever heard of maitake mushrooms? Also called hen-of-the-woods, they have amazing amounts of Beta-Glucans, which are beneficial to both an Overactive or Underactive Immune system.

Ashwagandha (Withania Somnifera) Root Extract (20:1)
This herbal root is a long-hailed Ayurvedic tonic of India. Used as a nutritious food and tonic, it may have adaptogenic properties that both protect and enhance an overactive or underactive immune system. Further, Ashwagandha is an effective antioxidant, nutrient-rich, well-studied, and widely known for its ability to help restore and improve energy.

Astragalus (Astragalus Membranaceus) Extract: 30% Polysaccharides
Used for thousands of years in Traditional Chinese Medicine (TCM) for helping support against colds, flu, and more. According to studies, the plant may help stimulate white blood cells, antibodies, and even interferons, all of which readily combat illnesses and viruses.

Burdock (Arctium Lappa) Root Extract (20:1)
In many parts of the world, burdock root has been consumed as both a food and for helping restore strength, cleansing the liver, and improving overall health.* Some preliminary studies reveal that this perceived effect of the root on health may be because it boosts immunity. The root has also been studied for its potential anti-inflammatory and blood pressure-lowering effects, yet more properties that could be related to immune protection.
