Marigold peoplein has powerful antioxidant properties. As an antioxidant, it can neutralize the free radiation activity of the human body and reduce the free radiation damage to organs. Currently, calendula has been shown to be beneficial for infant brain development. Many studies have focused on the link between calendula and reducing the risk of age-related diseases. After more than 100 clinical studies, Kemin's FloraGLO Lutein not only has good stability, but also has plant raw materials extracted from calendula, which is widely considered safe in the United States, non-GMO, vegetarian, gluten-free, etc. The natural health label proves that the vitreflavin of fruits and vegetables has the same molecular form and is more easily absorbed and utilized by the body, which is beneficial for visual function, skin health and cognitive health.
After entering the human body, Calendula can be combined with Jea Jantin to relieve eye fatigue caused by blue light. After years of scientific research and innovative development, FloraGLO can protect people by filtering harmful blue light. Become an excellent "anti-blue light brand" from the blue light injury of different ages. In addition, FloraGLO Lutein is also beneficial for brain and skin health.
Calendula Extract Lutein is very beneficial for the eyes and gills. Cold and cough are also the main pigments in the macular region of the human eye.
