Immune boost formula combines medicinal mushrooms with nutrients for the immune system. It contains mushroom extracts from Reishi and Shiitake, along with vegetable vitamin C from acerola and camu camu fruit extract, as well as vitamin E and zinc. The selective intake of vitamin C and zinc in Immune boost formula serves as a nutritional-physiological measure for maintaining the body's immune system, particularly during times of increased stress. Reishi and Shiitake are traditional extracts with a long history. Vital mushrooms such as Reishi (Ganoderma lucidum) and Shiitake (Lentinula edodes) have been used for over a thousand years and hold significance in the Asian region. The use and understanding of these mushrooms evolved independently in Japan, China, and India.
