The recommended serving is one capsule three times a day, which is the exact serving used in the clinical trials. However, people who are sensitive to stimulants have reduced the serving to as low as one capsule twice a day and have still seen results. As with any ingestible compounds, each individual reacts differently to INCNR8 ECA™. The effective serving depends on a person’s body weight, metabolism and overall health. You may want to start with one INCNR8 ECA™ capsule twice a day and gradually increase the serving to the recommended serving until you find what works best for your body.
