How does NSI® Astragalus Extract work?
Astragalus is native to northern China where, in the spring, the yellow root of a four to seven years old plant is collected, dried and used for medicinal purposes. It is used to increase metabolism, stamina, strength and vitality. It is one of the most important tonic herbs in China, used for night sweats, fatigue, weakness and loss of appetite. This popular energy tonic is thought to raise immune resistance and improve physical endurance.

NSI® Astragalus Extract contains flavonoids, polysaccharides, triterpene glycosides, amino acids, essential fatty acids and polysaccharides (the main nutrients that feed our bodies), and trace minerals that help strengthen the immune system. This potent formula helps support the body during times of fatigue and prolonged stress. It may also help rebalance the metabolism and return the body to a sense of general well-being.

NSI® Astragalus Extract helps activate the immune system, enhancing the body's natural ability to fight major diseases. When used during cold and flu season, it may help reduce the number of episodes or shorten their duration. The herb appears to increase the body's level of antibodies and interferon (the protein compound that slows the course of viral infection).

NSI® Astragalus Extract 1,000 mg is better because it:
- Provides the full spectrum of astragalus constituents for optimal immune support
- Contains the most potent and highest quality nutrients
- Provides a better value compared to other brands
