HemoHIM, is developed  by Korea Atomic Energy Research Institute (KAERI), initially for enhancing the immune system of the people working in the project. When its beneficial effect was noted, it was eventually opened and shared to the public. Immune deficiencies are often associated with decrease immune cells, declining cell activity and oxidative stress. The aging population in particular is often susceptible to declining immune system. It was found out that HemoHIM is able to stimulate the development of red blood cells (RBC), activate immune cells, as well as promoting recovery of the immune system against oxidative stresses. According to researcher Sung-Kee Jo, HemoHIM has been approved not only by the Korea Food and Drug Administration (KFDA) but also by US FDA as well, as the first health functional food for immune system improvement.
