Creatine and HMB: Enhancing Lean Body Mass

Creatine and β-Hydroxy-β-Methylbutyrate (HMB): Enhancing Lean Body Mass and Muscle Strength During a Weight-Training Program


The pursuit of optimizing athletic performance and enhancing muscle growth has led to the exploration of various dietary supplements. Two popular supplements, creatine and β-Hydroxy-β-Methylbutyrate (HMB), have gained considerable attention due to their potential benefits in promoting lean body mass and muscle strength. This blog aims to delve into the research conducted by Ewa Jówko et al., which examines the additive effects of creatine and HMB when combined with a weight-training program.

Creatine: A Powerful Ergogenic Aid

Creatine is a naturally occurring compound found in small quantities in meat and fish. It plays a vital role in producing adenosine triphosphate (ATP), the primary energy source for muscle contractions. Individuals supplementing with creatine can experience enhanced strength, power, and overall exercise performance by increasing intramuscular creatine stores.

Creatine supplementation has been extensively studied and consistently demonstrated to improve muscle strength and power output during resistance training. It achieves this by replenishing ATP levels rapidly and efficiently, allowing for more intense and prolonged exercise sessions. Additionally, creatine has been shown to increase muscle glycogen stores, enhance protein synthesis, and reduce muscle damage and inflammation, further contributing to muscle growth and recovery.

β-Hydroxy-β-Methylbutyrate (HMB): A Promising Anabolic Agent

HMB is a metabolite of the essential amino acid leucine. It has gained attention for its potential to promote muscle protein synthesis, prevent muscle protein breakdown, and stimulate muscle growth. HMB exerts its effects by modulating key signaling pathways involved in muscle protein metabolism.

Combined Effects of Creatine and HMB: A Synergistic Approach

The study conducted by Jówko et al. aimed to examine the additive effects of creatine and HMB supplementation on lean body mass and muscle strength during a weight-training program. The researchers recruited 41 experienced male weightlifters and divided them into four groups: creatine, HMB, creatine + HMB, and a placebo group.

The participants engaged in an eight-week weight-training program, and their body composition, muscle strength, and power output were assessed at baseline and the end of the study. The results demonstrated that all three supplement groups (creatine, HMB, and creatine + HMB) experienced significant increases in lean body mass compared to the placebo group. Moreover, the creatine + HMB group exhibited the greatest improvements in lean body mass, indicating a potential synergistic effect between these two supplements.


Based on the study conducted by Jówko et al., both creatine and HMB demonstrate the potential to increase lean body mass and promote muscle strength when combined with a weight-training program. Creatine enhances exercise performance and muscle growth through its role in ATP production and protein synthesis. HMB, on the other hand, supports muscle protein metabolism and acts as an anti-catabolic agent.

It is important to note that individual responses to creatine and HMB supplementation may vary. Furthermore, it is essential to consult with a healthcare professional before incorporating any new supplements into your regimen to ensure they align with your specific health needs and goals.

In conclusion, the study provides valuable insights into the potential benefits of creatine and HMB supplementation for individuals engaging in weight-training programs. Maintaining a balanced diet, regular exercise, and proper recovery remain the foundation for achieving optimal athletic performance and muscle growth.
