Final Answer:
Creatine, a popular supplement for muscle growth, naturally aids in energy production in muscles and tissues. Taken as a dietary supplement, it enhances muscle creatine content, positively affecting exercise performance. Other beneficial supplements for muscle development, alongside resistance training and a balanced diet, include protein supplements, beta-hydroxy beta-methylbutyrate (HMB), and omega-3 fatty acids.
Step-by-step explanation:
The query about the substance used for increasing muscle mass emphasizes that it is not a medicine but a supplement. Addressing this, the explanation clarifies that creatine, a naturally occurring molecule in the body, is a common supplement chosen for its positive effects on muscle cells and exercise performance. The mention of other supplements like protein supplements, HMB, and omega-3 fatty acids further reinforces the idea that individuals often turn to a combination of supplements to support muscle growth. This aligns with the understanding that enhancing muscle mass involves a holistic approach encompassing nutrition, resistance training, and specific dietary supplements.
