Vitamin C is well-known for immune-boosting. However, IMUGLO is formulated with 4 types of immune-enhancing ingredients, including PUREWAY-C vitamin C with higher absorption and retention rate compared to other form of vitamin C in the market. Moreover, Maritech organic fucoidan and ElderCraft elderberry extract are also ingredients that help to modulate immune system, reduce inflammation and relieve upper respiratory symptoms. In short, the health benefit of taking IMUGLO cannot be substituted by just taking higher dosage of vitamin C or other immune-boosting products.
