Performance Inspired Nutrition was founded by Mark Wahlberg and Tom Dowd, who first connected over their shared passion for the health and fitness world. They also shared something else: a frustration over the lack of clean, effective nutritional supplements available on the market. Mark and Tom realized that most of the products out there were packed with artificial sweeteners, fillers, and synthetic ingredients, and they wanted to make a change. That’s when Performance Inspired Nutrition was born. PI is a company committed to clean, effective nutritional supplements that are designed to help you meet your health and fitness goals.
