Why is Immunity So Important?
Your immune system is a complex system of interconnecting cells, tissues and organs that play a central role in your health. It is designed to recognize foreign invaders and mounts a response to destroy and eliminate these before they cause health issues. It develops antibodies so that your body can more quickly destroy these invaders should you be exposed to them again.
Staying healthy means giving your immune system the help it needs so that it can protect you all year long. Supporting your immune system with great nutrition is one of the best ways to get a leg up in keeping you well.

Yeast Beat-Glucan
1,3/1,6-Beta-glucans are a class of natural polysaccharides (polymers of sugars) that are present in the cell walls of certain plants and yeast.
Similar polysaccharides are also present in the cell walls of various microorganisms. Because of this, our immune cells regard these beta-glucans as “foreign” and elicit an immune response against them to prepare the body for defense.
Reishi Mushroom
A woody fungus that is widely cultivated in southern China. The mushrooms are sorted by hand, washed, sun-dried, and chopped. An extract is produced from the dried material in a process that removes essential oils.
Reishi mushroom has been historically used for thousands of years for immune support.
Panax Ginseng
A slow-growing plant native to Korea and northeastern China that is harvested for its gnarled roots. Roots must mature for 6 years or so before they can be harvested. Panax means “all healing” in Greek.
Elderberry
Prepared from the ripe, black berries of the black elder, a tall shrub native to Europe. Elderberries are rich in immune-supporting antioxidants.
Quercetin
Belongs to a group of natural plant pigments called flavonoids that give many fruits, flowers, and vegetables their colors.
Quercetin has potent antioxidant properties and is abundantly found in many fruits and vegetables.
Echinacea
A lavender flowering herb native to North America that is rich in antioxidants. The powdered extract is prepared from the dried root and leaves.
