Dietary Nitrate for Muscle Wasting
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores whether drinking beetroot juice can prevent muscle wasting when muscles aren't used, such as when wearing a knee brace. Researchers aim to determine if the nitrates in beetroot juice improve muscle function and energy use. Participants will be divided into two groups: one will drink nitrate-rich beetroot juice, and the other will consume a nitrate-free version. The trial seeks men who are generally active but not extreme athletes, and who haven't had recent leg injuries or serious heart conditions. As an unphased trial, this study offers participants the chance to contribute to innovative research on muscle health and nutrition.
Will I have to stop taking my current medications?
The trial requires that you stop taking certain medications, including antibiotics, phosphodiesterase inhibitors (like Viagra), proton pump inhibitors, antacids, xanthine oxidase inhibitors, hormonal contraceptives, or hormone replacement therapy. If you are on any of these, you would need to stop them to participate.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that beetroot juice, rich in dietary nitrate, is safe for consumption. Studies have found that drinking beetroot juice can enhance muscle performance during exercise without causing harm.
Participants in these studies consumed the juice, and researchers checked their muscle function shortly after. No serious side effects were reported. Beetroot juice contains more nitrate than typically found in a regular diet, indicating it is safe to consume in larger amounts.
Overall, evidence suggests that most people tolerate beetroot juice well, making it a safe option for those considering participation in a trial involving dietary nitrate.12345Why are researchers excited about this trial?
Most treatments for muscle wasting focus on exercise regimens and protein supplementation. But beetroot juice, rich in dietary nitrate, offers a unique approach by potentially enhancing blood flow and oxygen delivery to muscles. This mechanism may support muscle recovery and growth more effectively. Researchers are excited because beetroot juice could offer a natural, easily accessible alternative with fewer side effects compared to traditional treatments.
What evidence suggests that dietary nitrate might be an effective treatment for muscle wasting?
Studies have shown that beetroot juice can improve muscle performance. One study found that beetroot juice made muscles slightly stronger. Research also shows that nitrate, a substance in beetroot juice, boosts exercise performance, especially for short, intense activities. Additionally, beetroot juice, high in nitrate, has been reported to reduce muscle pain and aid faster recovery after exercise. In this trial, participants will receive either nitrate-rich beetroot juice or a nitrate-free placebo. These findings suggest that beetroot juice could help prevent muscle loss.26789

Are You a Good Fit for This Trial?
This trial is for young, healthy men who can safely consume beetroot juice. It's not suitable for those with conditions that could be worsened by nitrates or anyone unable to wear a knee brace for two weeks.Inclusion Criteria
