How it Works

Nature’s Sunshine Immune Stimulator combines ingredients that nourish and strengthen the immune system. It provides powerful antioxidants for DNA protection. The beta-glucans included in the formula promote the production of cells that help protect the body while arbinogalactan, also included in the formula, stimulates those cells to protect. Immune Stimulator also helps the body maintain a healthy environment that beneficial intestional flora, such as bifidobacteria and lactobacillus, will flourish in. The formula contains colostrum, the first milk produced by mammals after giving birth, a substance know for its immune-enhancing powers. Other ingredients in Immune Stimulator are reishi mushroom and maitake mushroom which also stimulate natural killer cells and activate macrophages and cordyceps which offers gene protection.


Beta-glucans, arabinogalactan, colostrum, cordyceps mycelia, reishi mushroom mycelia, maitake whole mushroom

Recommended Use

Take 1 capsule between meals two or three times daily. For periods of immune system stress: Take 1 capsule 6-10 times daily.

Great product, used it for years

A friend introduced this to me 15 or 20 years ago when I was coming down with something. It stopped the "bug". Since then I take it once a day, more if I feel I am coming down with something.
