It’s generally safe to take Glutamine every day. Glutamine is a naturally occurring amino acid that you already get from many protein-rich foods like meat, fish, beans, and dairy. Taking it as a supplement simply helps you get more, which can be useful if you’re training hard, recovering from illness, or want extra support for gut and immune health.

No, Glutamine and creatine work in completely different ways, so one isn’t “better” than the other. Creatine helps increase strength, power, and muscle size by providing quick energy for your muscles during short, intense activities like weightlifting or sprinting. Glutamine, on the other hand, supports recovery, gut health, and immune function. Many athletes actually use both supplements because they complement each other rather than replace one another.
