Founded in 2014 at Tokushima University’s Faculty of Engineering, Saisei Pharma is a pioneering biotech company dedicated to immune health and longevity. We develop and manufacture the world’s first natural immune-supporting health food series, the MAF Series, including MAF Capsules, MAF Spray, M-Lollies, and M-Powder.
Our products are available through our official online store for both domestic and international customers. Now headquartered in Osaka, manufacturing takes place at our Moriguchi Factory (Certification No. 26518), recognized by the Japan Health and Nutrition Food Association for quality and safety.
By combining decades of research with natural, high-quality MAF products and clinical expertise, we enable your immune system to defend, restore, and renew, helping you live with greater vitality, resilience, and cellular health.
GcMAF stands for Gc protein–derived Macrophage Activating Factor. At Saisei, we are proud to collaborate with leading Japanese universities to advance research in immune health and modern medicine.
In Japan, we offer several types of GcMAF, each with a specific purpose and potential: serum GcMAF, autologous GcMAF, Dietary MAF, and recombinant MAF. Our focus is on the new generation of GcMAF products that support immune balance naturally.
Have you ever wondered why we age? One of the key reasons is the shortening of telomeres, the protective caps at the ends of chromosomes, while the Klotho gene plays an important role in regulating stress, inflammation, and cellular recovery. All these processes are closely connected to vitality and aging.
Our Dietary MAF products provide nutritional support to the immune system and can become part of a daily routine for improved overall well-being, longevity, and cellular protection.
