About Nature’s Sunshine Immune Stimulator
Your immune system works around the clock to protect your body from environmental challenges and maintain your overall health. Nature’s Sunshine Immune Stimulator provides comprehensive support for your natural defense mechanisms through a scientifically formulated blend of beta-glucans, arabinogalactan, and traditional immune-supporting mushrooms.
This unique formula combines the power of polysaccharides with time-honored Traditional Chinese Medicine ingredients to help maintain healthy immune responses. The foundation of this formula rests on beta-glucans and arabinogalactan, two well-researched compounds known for their ability to support immune cell function and activity.
The Science Behind Immune Support
Beta-glucans are naturally occurring polysaccharides found in the cell walls of certain fungi, yeasts, and plants. These complex carbohydrates have been extensively studied for their ability to support immune cell communication and function. The beta-glucans in Immune Stimulator are derived from Saccharomyces cerevisiae, providing 200mg per serving of these valuable immune-supporting compounds.
Arabinogalactan, extracted from larch trees, adds another layer of immune support. This fiber-like polysaccharide has been shown to support the activity of natural killer cells and other important immune cells, helping your body maintain its natural defense mechanisms.
Traditional Mushroom Wisdom Meets Modern Science
The formula is enhanced with a proprietary blend of mushrooms that have been valued in Traditional Chinese Medicine for thousands of years. Reishi mushroom mycelia, often called the “mushroom of immortality,” has been treasured for its ability to support overall vitality and immune function. Maitake whole mushroom brings its own unique polysaccharides to support immune health, while cordyceps mycelia adds adaptogenic properties that may help the body respond to stress.
Nature’s Sunshine sources these mushrooms from the fertile mountains and valleys of Qingyuan county in China’s Zhejiang province, an area renowned for its ideal environmental conditions for mushroom cultivation. The company has partnered with local farmers for over 20 years, ensuring sustainable growing practices and the highest quality mushrooms.
Enhanced with Colostrum
The formula is further strengthened with colostrum from milk, nature’s first food that provides naturally occurring immunoglobulins and immune factors. Colostrum contains various bioactive compounds that support immune function and help maintain the body’s natural defense systems.

Frequently Asked Questions
Beta-glucans are complex carbohydrates (polysaccharides) found in the cell walls of certain fungi, yeasts, and plants. They support immune function by helping to stimulate immune cells, including macrophages, T-cells, and natural killer cells, which play important roles in your body’s natural defense mechanisms.
Arabinogalactan is a polysaccharide extracted from larch trees that works synergistically with beta-glucans to support immune cell activity. Together, these compounds help maintain healthy immune responses and support your body’s natural defense systems.
Reishi, maitake, and cordyceps mushrooms have been used in Traditional Chinese Medicine for thousands of years to support immune health and vitality. These mushrooms contain unique polysaccharides and bioactive compounds that complement the beta-glucans and arabinogalactan for comprehensive immune support.
