Preparing for the inevitable

I’ve been using “Optimal Immune” from Primal Herb since my last bout of C19.
I’d had my three Jabs of immunizations, but those vaccines could not cover the full spectrum of C-19 viruses that materialize. Having caught C19 and suffered from severe flu-like symptoms for a full two weeks, I decided I needed backup. It’s important to feel our best.
Since taking Optimal Immune this winter, I’ve been flu and C19-free. I also notice a better reaction to some smaller autoimmune issues.
After purchasing this product twice, I’m staying with it. Honestly… the best products for a reasonable cost on the health product market.
I’ve tried other products and swear by all of them.
They’re all top-rated!

Immuno-compromised relief

This product was one of the main factors that got me off chemotherapy treatment for sarcoidosis. I’ve been taking it regularly for almost 2 yrs and have had only 1 sarcoid flare up during that time

Formulated With Pure Effective Ingredients

Each Ingredient Must-Have Historical Use & Independent Studies!

Chaga Mushroom Extract

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 Mushroom Extract

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 Mushroom Extract

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 Extract

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 Extract

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 Extract

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.*

Optimal Immune also includes the addition of piperine, the active alkaloid chemical found in black pepper. It immediately increases the bioavailability of the powerful compounds in these mushrooms and herbs so that you can feel the difference!*
