What are the Benefits of HMB?

Benefits for Muscle Growth

HMB supplementation offers notable advantages, particularly in promoting muscle growth. This is achieved by inhibiting protein breakdown in muscles, a crucial process for muscle development and maintenance.

But how does exactly HMB benefit for muscles, this video will answer this question:

A study involving over 15 elderly men asserts that combining HMB with Arginine and Glutamine improves muscle function for men undergoing ADT for prostate cancer without causing significant side effects. [11]

In a trial involving 41 male volunteers, those supplemented with HMB experienced a rapid and sustained increase in muscle mass [5]. The muscle-enhancing effects of HMB can be attributed to its ability to stimulate the mTOR signaling pathway and growth hormones [3, 6].

Therefore, incorporating HMB into your nutrition regimen can benefit individuals seeking to enhance muscle mass and improve overall physical performance.

Reduce Muscle Breakdown

HMB helps to reduce muscle breakdown

HMB has demonstrated a significant impact on reducing muscle breakdown. In a clinical trial involving 15 cancer patients, HMB showed a marked reduction in muscle atrophy by inhibiting the ubiquitin-proteasome system. This protein degradation process is directly linked to muscle wasting [6].

The effect of HMB on muscle atrophy caused by cancer is also supported. In a study conducted on mice with breast cancer, HMB was observed to reduce inflammatory signals in cancer cells, reduce muscle atrophy, and provide protection against weakness [12].

This protective effect of HMB provides a valuable resource for individuals at risk of muscle wasting due to various conditions, including aging, prolonged bed rest, or certain diseases.

By supplementing with HMB, it may be possible to slow down muscle degradation, thereby maintaining muscle health and physical function.

Improve Exercise Adaptations

During the initial phase of high-intensity training, the supplementation of HMB can enhance the body's adaptive response.

According to a study, untrained individuals who took HMB as a supplement significantly enhanced their ability to adapt to intense exercise [9].

Nevertheless, it is essential to highlight that this effect diminishes after approximately six weeks of training. This suggests that the influence of HMB on exercise adaptation is most significant during the initial phases of a new training program.

Incorporating HMB into the diet can accelerate and enhance adapting to increased physical demands for those starting or intensifying their fitness journey.

Physical Exercise in Older Adults

Physical exercise helps improve the health and well-being of older adults, serving as a crucial component in maintaining their overall vitality and quality of life.

Although HMB is widely known for its involvement in muscle development, its primary benefit extends beyond enhancing muscle growth in this age group.

Research suggests that when combined with physical exercise, HMB supplementation may have a minimal effect on muscle mass in older adults compared to exercise alone [2, 9].

On the contrary, this group's primary advantages of HMB supplementation lie in its potential cognitive benefits. Studies indicate that when combined with regular physical exercise, HMB supplementation can significantly assist in preventing cognitive decline and Alzheimer's disease among older adults [2].

Seniors should consider incorporating additional HMB intake, not only to maintain muscle but also for the significant cognitive health benefits it provides.

May Combating Aging

As people grow older, an inherent decrease in muscle strength occurs, which causes a loss of independence and the development of frailty among older adults.

By promoting muscle development and preventing muscle atrophy, HMB has the potential to support physical function and independence in this specific population [7].

Furthermore, recent studies indicate that HMB has the potential to promote cognitive well-being in older individuals, potentially mitigating cognitive decline and the onset of Alzheimer's disease [2].

Supplementing with HMB can play a dual role in preserving physical fitness and cognitive function as we age.

Other Benefits

Emerging studies have begun to reveal less commonly known benefits of HMB that extend beyond its well-established muscle-promoting effects.

  • Research suggests that HMB supplementation may significantly aid in reducing inflammation and facilitating muscle recovery post-injury [1]. This is beneficial for athletes or individuals undergoing rehabilitation from musculoskeletal injuries.
  • Another intriguing area of HMB research is its potential role in weight management and obesity prevention. Evidence suggests that HMB could positively impact the body's antioxidant system and contribute to weight loss [1]. This attribute of HMB could pave the way for new strategies in managing obesity and related health issues.
  • HMB shows promise in cardiovascular health, as studies indicate it can minimize the risk of cardiovascular diseases [1].

Despite these promising findings, it is essential to note that further research is required to validate and understand these benefits fully.

What are the Side Effects of HMB?

While HMB's benefits are substantial, it's essential to consider potential side effects and safety precautions.

In a 91-day mouse model test, no adverse effects were observed. Extensive experiments involving individuals of various ages and genders have consistently demonstrated the safety of HMB, with no significant negative impacts on the human body [9].

Nevertheless, some individuals have reported minor side effects, including skin, mouth, and limb discomfort after HMB supplementation.

However, these effects are typically rare and minimal. As with any supplement, it's essential to remember that reactions can vary from person to person.

How Much HMB Should You Take to be Safe?

It's crucial to understand the correct dosage to experience its effects optimally.

Various studies have tested different groups using HMB doses ranging from 1.5g to 6g per day, exploring the threshold at which HMB's effects are maximized. The consensus among researchers is that a daily dosage of 3g HMB is as effective as 6g.

The optimal daily intake of 3g of HMB maximizes its effects for most individuals.

How to Take HMB to Maximum Effectiveness

HMB can be consumed in two primary forms: capsules or powder.

  • Those choosing HMB capsules can be ingested directly, ideally with a glass of filtered water, to facilitate easier swallowing.
  • If you prefer HMB in powder form, it can be mixed with sufficient filtered water or a sports drink.

The optimal time for HMB intake varies among individuals, but many users have reported the best results when consuming HMB within an hour before exercise.

Regardless of the method of ingestion, it is essential to carefully follow the manufacturer's instructions regarding quantity and timing to achieve the maximum benefits of HMB supplementation.

Who Should and Shouldn't Take HMB?

HMB is highly beneficial for people involved in high-intensity workouts or those who want to improve their muscle strength and endurance.

It is beneficial for older adults, as it maintains muscle mass and contributes significantly to cognitive health, potentially preventing cognitive decline and the onset of Alzheimer's disease.

HMB is also suitable for individuals experiencing excessive muscle fatigue, patients with conditions related to muscle atrophy, and those looking to prevent weight-related health issues like obesity and heart disease.

HMB is generally perceived as having no significant side effects, making it suitable for almost anyone.

Despite being generally safe with minimal side effects, individuals with specific allergies or underlying health conditions should get advice from a healthcare provider before starting HMB supplementation.

Mixing HMB With Other Supplements

HMB doesn't have to be taken alone; it's possible to combine it with other supplements to enhance its effects, for example, potentially:

  • The combination of HMB with vitamin D3 has increased muscle strength and physical functions in older adults, even without an exercise program [7].
  • Another interesting combination is HMB with creatine. A study suggests that combining HMB and creatine has the potential to reduce cortisol levels more effectively than using these two nutrients separately. This will help individuals decrease stress when taking this combination [4].

However, getting advice from a healthcare provider before starting any new nutrient supplementation is crucial, especially if it involves mixing various supplements. This ensures the combination is safe and suitable for your health needs.
