Clinical Studies

We are currently conducting several clinical studies with major universities around the world in order to benchmark the efficacy of various products. Three clinical studies using our Formula 1 Nutritional Shake Mix were done: one at UCLA*, United States, one at the University of Ulm, Germany and one at Seoul National University Hospital in Korea. The studies conducted demonstrated that drinking Formula 1 shakes every day as meal replacements is an effective way to manage weight. A clinical study using Niteworks was also conducted at UCLA which concluded that the anaerobic threshold in men between the ages of 50 and 73 increased when drinking Niteworks every night.
