Natural Factors RegenerLife - A mitochondrial optimization formula that contains a potent combination of targeted nutritional compounds shown to optimize mitochondrial function. These vegetarian capsules support the body’s antioxidant defence systems, help reduce symptoms of fatigue, and contribute to brain, muscle, and heart health.

RegenerLife helps reduce the symptoms of perceived stress, such as pain, fatigue, sleeplessness, irritability, and reduced quality of life. This vegetarian formula is a great choice for adults with age- or health-related declines in mitochondrial function, people concerned about their exposure to toxins, and individuals who want a stimulant-free supplement to help improve strength and power in repetitive bouts of brief, highly intense physical activity.
