What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores whether a supplement called tributyrin can enhance health and performance in individuals who are not very active. It examines how tributyrin might improve gut and immune health, sleep, and exercise performance while reducing inflammation. Participants will take either a tributyrin supplement or a placebo (a look-alike without active ingredients) for four weeks, with various health assessments conducted throughout the study. Those who exercise less than 150 minutes a week may be suitable candidates. As an unphased trial, this study offers a unique opportunity to contribute to scientific understanding and potentially improve personal health outcomes.

Do I have to stop taking my current medications?

The protocol does not specify if you need to stop taking your current medications. However, you cannot take supplements that impact the microbiome, hydration, core temperature, or exercise performance.

Is there any evidence suggesting that tributyrin is likely to be safe for humans?

Research has shown that tributyrin, particularly in its CoreBiome form, is generally safe. Studies have found that CoreBiome can be absorbed in the colon, which benefits gut health. Experts consider tributyrin GRAS (Generally Recognized as Safe), indicating its safety for intended use.

Tributyrin has been studied for various health benefits, including gut health and weight management. Although specific side effects are not detailed in the sources, its GRAS status suggests serious side effects are unlikely. However, individual reactions can vary, so staying informed and consulting healthcare providers if concerns arise is advisable. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Tributyrin is unique because it introduces a different approach to enhancing health and performance by targeting gut health directly. Unlike many current treatments that focus on symptoms, tributyrin acts as a source of butyrate, a short-chain fatty acid that supports gut lining integrity and reduces inflammation. Researchers are excited about tributyrin because it could offer a natural way to improve gut health, which might translate into better overall health and athletic performance. This potential makes it a promising alternative to standard dietary supplements and medications that often do not address the root cause of gut-related issues.

What evidence suggests that tributyrin might be an effective treatment for improving health and performance?

Studies have shown that tributyrin, which participants in this trial may receive as CoreBiome, can improve gut health and strengthen the immune system. Research indicates that it also supports the growth of beneficial gut bacteria, potentially enhancing digestion and nutrient absorption. In animal studies, tributyrin improved growth, suggesting similar benefits for human health and performance. Additionally, tributyrin increases butyrate levels in the gut, which can reduce inflammation and improve overall health. These findings suggest that tributyrin could effectively enhance various health markers. ^{2 6 7 8 9}
