What is the purpose of this trial?

This trial tests a new treatment called MIB-626, which involves taking a supplement to determine if it enhances fitness when combined with exercise. The study targets healthy, highly active individuals who regularly engage in intense exercise. Participants will receive either MIB-626 or a placebo (a pill with no active ingredients) alongside their usual workout routine or a specific high-intensity exercise plan. It suits those already physically fit and accustomed to vigorous exercise routines, such as running or weight training. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group, allowing participants to contribute to the development of potentially beneficial fitness enhancements.

Do I have to stop taking my current medications for the trial?

You may need to stop taking certain supplements, especially those containing niacin or its related compounds, at least 2 weeks before starting the trial. Herbal supplements and performance-enhancing substances are also prohibited. If you're taking any of these, you'll need to stop before participating.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that MIB-626, which includes a compound called NMN, is generally safe for people. Studies indicate that taking up to 1250 mg of NMN daily for 4 weeks does not cause major side effects, and participants tolerated it well. Another study found that MIB-626 increased NAD+ levels without causing inflammation or kidney problems.

High-intensity interval training (HIIT) is also considered safe for the exercise component. Even older adults with heart conditions have safely participated in supervised HIIT programs. HIIT helps improve fitness and overall health.

In summary, previous research has demonstrated the safety of both the MIB-626 treatment and the exercise routine used in the trial. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about MIB-626 because it uses nicotinamide mononucleotide (NMN), a compound that may stimulate cellular energy production by boosting NAD+ levels. Unlike traditional exercise alone, MIB-626 might enhance the body's natural ability to repair and maintain itself, potentially leading to improved physical performance and recovery. This treatment is unique because it combines the benefits of exercise with a novel biochemical approach, possibly offering quicker and more effective results than exercise alone.

What evidence suggests that this trial's treatments could be effective for healthy adults?

Research has shown that MIB-626, which includes NMN (a compound aiding energy and cell repair), can increase NAD levels in the blood. Studies have found that NMN is safe and can reduce tiredness and improve leg strength in the afternoon. It might also help with aging-related issues, such as cellular stress and DNA damage.

In this trial, some participants will receive MIB-626 alongside their usual physical activity, while others will combine MIB-626 with a standardized, progressive, high-intensity, multidimensional exercise program. High-intensity exercise has been proven to improve heart and lung fitness, reduce body fat, and boost overall physical performance. These findings suggest that MIB-626 and high-intensity exercise together could enhance physical fitness and health. ^{1 6 7 8 9}

In a 1-year randomized controlled trial involving 80 individuals with type 2 diabetes, neither moderate-intensity continuous training (MICT) nor high-intensity interval training (HIIT) led to compensatory changes in non-exercise physical activity (NEPA) or estimated thermogenesis (NEAT) on non-training days.

Participants who were classified as low-responders or high-responders in terms of body weight and fat mass reductions did not show significant differences in NEPA or NEAT compared to control groups, indicating that exercise intensity did not affect these non-training day activities.

A meta-analysis of 10 randomized controlled trials involving 324 participants showed that HMB supplementation significantly reduces serum levels of creatine kinase (CK) and lactate dehydrogenase (LDH), which are markers of exercise-induced muscle damage.

The effectiveness of HMB in promoting recovery from muscle damage appears to be time-dependent, with significant benefits observed in studies lasting 6 weeks or longer, suggesting it could be a valuable recovery aid for athletes.

In a systematic review of 36 studies involving 1561 participants, it was found that reductions in non-exercise physical activity (NEPA) and non-exercise activity thermogenesis (NEAT) occurred in 63% of diet-only, 27% of combined diet/exercise, and 23% of exercise-only intervention arms, indicating that people often compensate for weight loss efforts by becoming less active.

Participants who experienced a decrease in NEAT lost twice as much weight compared to those who did not, suggesting that the degree of energy imbalance can lead to energy conservation behaviors, although the study's limitations may affect the reliability of these conclusions.

Physical activity improves insulin sensitivity in both healthy individuals and those with insulin resistance, with effects lasting at least 16 hours after a single exercise session due to mechanisms like increased GLUT4 transporters in muscle cells.

Regular physical training enhances insulin sensitivity even further by promoting adaptations in glucose transport and metabolism, making it a crucial strategy for preventing and treating insulin insensitivity, particularly in individuals with non-insulin-dependent diabetes mellitus (NIDDM).
