"Essential Daily Supplements for Muscle Growth and Fitness Maintenance"

Fitness expert Hayley Madigan, a former bodybuilder and personal trainer, shared her daily supplement regimen with Business Insider, including whey protein, creatine, glutamine, HMB, ashwagandha, and ZMA. While some supplements like whey protein and creatine are well-researched and known to aid muscle growth and workout performance, others such as glutamine, HMB, ashwagandha, and ZMA require more research to support their claimed benefits. Madigan's approach to supplements has evolved as she's gotten older, focusing on those that help her perform and feel her best while avoiding those that cause energy crashes or digestive issues.
