Product Information


ANDREW LESSMAN'S Immune Factors is an extremely comprehensive blend of nutrients, botanicals and mushroom extracts to support a healthy immune system. Immune Factors begins with our high potency B-complex, along with our non-acidic vitamin C – all of which are essential for a healthy immune system. They are also not readily available from the diet and easily depleted by stress and life. We add 2 standardized extracts of Echinacea, along with extracts of Goldenseal, Berberine, Astragalus and Black Currant. All of these plant-based extracts have been used for centuries to optimize immune system function and modern research has validated their benefits. We also add our unique, proprietary blend of organic standardized extracts of immune supportive mushrooms, including Turkey Tail, Reishi, Chaga, Maitake, Shiitake, Cordyceps, and Agaricus. The combined benefits of all these remarkable ingredients make Immune Factors a uniquely powerful opportunity to naturally support immune system function.

Employees of this wonderful company, Thank You! To all the employees of this wonderful company, Thank You! With this Covid 19, and being 75 years old, I was introduced to your products through my daughter-in-law. Being a 75 year old woman at the time, I wasn’t much of a believer in taking vitamins. She introduced me to ProCaps Immune Factors, Vitamin C 500 Complex, Vitamin D3 5000, and Ultimate Women’s Wellness vitamins. I believe that is what got me thru this past year, and having Covid 19 with little to no symptoms. One of my favorites is the Marine Collagen Peptides with MSM, I add it to whatever I’m drinking with breakfast every morning. I can see the difference in my skin, even as old as it is!

Hard As A Rock I have had the same issue with my immune factor as Lucia, FL. My pills got hard and I discovered it by accident when I decided to try shakes. I pulled my capsules apart and put the powder into my shake. The immune factor was as hard as a rock. I actually had to take a steak knife and saw it back to powder. I couldn't even break them. I also called customer service with no answer as to why. I use all Andrew Lessman products and that is the only one that gets hard. I put mine in the refrigerator now and they stay powder. I am so glad as they are the reason I stay healthy. So try refrigerating your immune factor.
