Rheo H. Blair

Rheo H. Blair was a pioneering nutritional supplement company founded by the influential nutritionist Rheo H. Blair (born Irvin Johnson) in the early 1950s. Based in Los Angeles, the company became legendary within the bodybuilding community for its high-quality protein powders, specifically a revolutionary blend of milk and egg proteins that challenged the soy-based standards of the time. The company's products, including Blair's Protein and Liver Extract, were utilized by iconic figures such as Arnold Schwarzenegger and Larry Scott, as well as various Hollywood celebrities. Although the original business ceased operations in the late 1980s following Blair's death, its nutritional philosophies and specific formulations continue to be marketed by modern successors and remain a cornerstone of sports nutrition history.
