One of our best selling supplements for years, Coryza Forte® is a unique blend of botanicals, bioflavonoids, vitamins and minerals formulated to support a healthy immune system.‡
- Vitamin C is a potent antioxidant and an essential micronutrient. Vitamin C supports immune health by supporting the natural and adaptive immune system. Vitamin C supports the barrier function against pathogens and promotes the oxidant scavenging activity of the skin and accumulates in the cells which protect the body from harmful particles which provides a number of benefits, including microbial killing. Vitamin C deficiency results in impaired immunity and higher susceptibility to infections.‡
- Zinc, especially when taken with vitamin C, has been found to reduce the incidence, and improve the outcome of various respiratory illnesses.‡
- Bioflavonoids, including hesperidin and quercetin, are known for their antioxidant activity and anti-allergic properties including stimulation of immune system, antiviral activity, inhibition of histamine release, and a decrease in pro-inflammatory markers.‡
- Echinacea has been the subject of multiple clinical studies which have shown benefit regarding supporting the immune system, primarily against the common cold.‡
