Which is better, HMB or creatine?

In the realm of sports supplementation, HMB (β-hydroxy β-methylbutyrate) and creatine have gained significant attention for their potential to enhance athletic performance. Both supplements aim to improve muscle growth and strength, but they operate through distinct mechanisms, leading to unique benefits and applications.

HMB, a metabolite of the essential amino acid leucine, is primarily known for its anti-catabolic properties. It helps reduce muscle breakdown and aids in recovery by mitigating muscle damage. HMB also plays a role in stabilizing cell membranes and promoting muscle protein synthesis. Additionally, it may enhance endurance capacity and mitochondrial biogenesis by activating PGC-1α, which can lead to improved fat oxidation.

Creatine, on the other hand, is widely recognized for its ability to increase strength, power output, and muscle mass. It functions by increasing the body’s store of creatine phosphate, a crucial energy substrate for high-intensity exercise. Creatine supplementation has consistently shown improvements in power output and muscle strength, making it a staple for athletes engaged in high-intensity, anaerobic sports.

When comparing the two supplements, creatine has a more substantial body of research supporting its efficacy. Studies have shown that daily consumption of 3-5 g of creatine monohydrate can improve various athletic performance measures, including maximal strength, speed, and recovery . Creatine may also reduce protein breakdown and muscle damage while increasing muscle protein synthesis, ultimately leading to increased lean mass .

HMB, while beneficial, may not have as significant an impact on muscle damage or strength when used alone . However, it shines in situations where muscle protein synthesis is accelerated, such as during resistance training or following muscle damage .

The choice between HMB and creatine ultimately depends on individual goals and training regimens. For those primarily focused on increasing strength and power output, creatine may be the better choice. Athletes looking to enhance recovery and reduce muscle breakdown might lean towards HMB.

Interestingly, some research suggests that combining HMB and creatine could potentially offer synergistic effects, enhancing strength and promoting favorable body composition adjustments . However, more studies are needed to fully understand the benefits of this combination.

In conclusion, while both supplements have their merits, creatine has a more robust scientific backing for improving strength and muscle mass. HMB may be more suitable for those prioritizing recovery and muscle preservation.

Understanding HMB and Creatine

What is HMB?

HMB, or beta-hydroxy beta-methylbutyrate, is a naturally occurring substance produced when the body breaks down leucine, an essential amino acid . It’s found in small amounts in foods like grapefruit, alfalfa, and catfish, but the body also produces it naturally . HMB has gained attention in the fitness community for its potential to aid muscle growth and prevent age-related muscle loss .

HMB plays a crucial role in muscle protein anabolism by stimulating the mechanistic Target of Rapamycin (mTOR) signaling pathway, which increases protein synthesis and reduces muscle protein breakdown . It also has antioxidant and anti-inflammatory properties that help mitigate muscle loss .

What is Creatine?

Creatine is a compound made from three amino acids and is primarily found in skeletal muscles and the brain . The body produces about 1 gram of creatine per day in the liver, pancreas, and kidneys . It’s also obtained through diet, especially from protein-rich foods like red meat and seafood .

Creatine serves as a natural source of energy for muscles, helping them contract during physical activity . It’s stored in muscles as phosphocreatine, which is used to produce adenosine triphosphate (ATP), the primary energy source for cells .

How They Work

HMB works by enhancing protein synthesis and reducing protein breakdown in muscles. It activates the mTOR pathway, which is crucial for muscle growth . HMB also improves endurance capacity and enhances mitochondrial biogenesis by activating PGC-1α, leading to increased fat oxidation .

Creatine, on the other hand, functions by increasing the body’s stores of phosphocreatine, which helps rapidly produce ATP during high-intensity, short-duration exercises . This leads to improved performance in activities like weightlifting and sprinting . Creatine supplementation has been shown to increase muscle mass, strength, and power output .

Both supplements have shown potential benefits for athletic performance and muscle growth. HMB is typically taken in doses of 3 grams per day , while creatine is often consumed in doses of 3-5 grams daily . However, individual responses may vary, and it’s always advisable to consult with a healthcare professional before starting any supplementation regimen.

Does HMB affect testosterone?

The relationship between HMB (β-hydroxy β-methylbutyrate) supplementation and testosterone levels has been a subject of interest in sports nutrition research. Studies have shown mixed results, but some evidence suggests that HMB may have a positive impact on testosterone levels under certain conditions.

A meta-analysis of seven studies, involving 235 participants, examined the effects of HMB consumption on hormone levels in athletes. While initial analysis showed no significant overall effect on testosterone concentrations, further investigation revealed some interesting findings. Subgroup analysis based on exercise type indicated a significant increase in testosterone concentration in athletes engaged in combined aerobic and anaerobic sports. This increase was quantified as a weighted mean difference of 1.56 (95% CI: 0.07, 3.05; p = 0.040).

The duration of HMB supplementation appears to play a crucial role in its effects on testosterone levels. Studies lasting longer than six weeks showed a significant increase in testosterone concentration compared to shorter interventions. This suggests that the hormonal benefits of HMB may require extended supplementation periods to manifest.

One study comparing the effects of creatine monohydrate (CrM) and HMB supplementation found that the combination of these supplements led to an increase in testosterone levels and an improved testosterone to cortisol (T/C) ratio after 10 weeks of supplementation. This combination showed a synergistic effect on testosterone and T/C ratio, outperforming individual supplementation of either compound.

It’s important to note that while some studies have shown positive effects, others have found no significant impact of HMB on testosterone levels. The variability in results may be due to differences in study design, participant characteristics, and exercise protocols.

The potential increase in testosterone levels associated with HMB supplementation could be beneficial for athletes, as testosterone plays a key role in training adaptation and recovery. However, more research is needed to fully understand the mechanisms behind these effects and to determine the optimal conditions for HMB supplementation to influence testosterone levels.

Can I take HMB and creatine together?

The combination of HMB (β-hydroxy β-methylbutyrate) and creatine monohydrate (CrM) has gained attention in the sports nutrition field. Research has explored how combining these supplements may affect exercise performance and muscle building .

A review of six studies, involving 201 athletes and resistance-trained individuals, examined the effects of taking HMB with creatine. The findings showed that consuming 3 grams of HMB along with varying doses of creatine significantly improved strength and high-intensity exercise performance. Additionally, this combination aided muscle growth and reduced body fat .

However, the results across studies have been mixed. While some research demonstrated that the combination enhanced athletic performance and increased testosterone levels, other studies found no additional benefits compared to taking creatine alone .

The potential synergistic effect of HMB and creatine is attributed to their different physiological mechanisms. HMB can increase protein synthesis by stimulating mTOR phosphorylation and enhancing the growth hormone-insulin-like growth factor-1 (GH-IGF-1) axis . Creatine, on the other hand, can improve muscle glycogen storage by increasing AMP-activated protein kinase (AMPK) phosphorylation and GLUT4 translocation .

A systematic review analyzing the efficacy of combining CrM and HMB revealed interesting results. The combination of 3-10 g/day of CrM plus 3 g/day of HMB, taken over 1-6 weeks, showed more significant improvements in strength performance, anaerobic performance, and body composition compared to taking them individually .

Specifically, the combined supplementation appeared to increase fat-free mass (FFM) and decrease fat mass (FM) more effectively than when taken separately . However, it’s important to note that not all studies found significant changes in body composition .

While the combination of HMB and creatine shows promise, more research is needed to fully understand their combined effects. Athletes and fitness enthusiasts considering this supplement combination should consult with a healthcare professional or sports nutritionist to determine if it’s appropriate for their individual needs and goals.

Recommended Dosages

HMB Dosage

The recommended dosage for HMB (β-hydroxy β-methylbutyrate) typically ranges from 1 to 3 grams daily . This dosage is considered effective for reducing muscle mass losses over time, serving an anticatabolic purpose. Interestingly, HMB is said to be 20-fold more potent than leucine for this purpose, making it equivalent to 20–60 g of leucine supplementation .

HMB is water-soluble and excreted in urine, with approximately half of the supplemented HMB lost through this process . To maintain steadier blood levels and potentially enhance effectiveness, it’s advisable to divide the daily HMB dosage into three separate doses throughout the day .

Creatine Dosage

Creatine supplementation often begins with a “loading phase” to quickly increase muscle creatine content. This phase typically involves consuming about 20 grams of creatine daily, split into 4-5 doses, for 5-7 days . Following the loading phase, a lower maintenance dose of 3-5 grams per day is recommended .

However, some research suggests that a loading phase may not be necessary. A study found that taking 3 grams of creatine daily for 28 days effectively increased creatine store levels compared to non-supplementation . This approach, while taking longer to maximize muscle stores, can be equally effective and may cause less digestive discomfort for some individuals .

Timing Considerations

The timing of HMB and creatine supplementation can influence their effectiveness. For HMB, when taken to mitigate exercise-induced muscle damage, it’s recommended to consume it 30-60 minutes before a workout if using the free acid form, or 60-120 minutes before if using the calcium salt form .
