What is the purpose of this trial?

This trial aims to assess how a daily prebiotic and probiotic supplement affects general health, particularly digestive comfort. Researchers will randomly assign participants to either a supplement group or a placebo group (receiving a lookalike supplement with no active ingredients). Participants will log their food intake, provide stool samples, and have blood drawn. The study seeks healthy individuals between 18 and 50 who occasionally experience mild digestive issues, such as bloating or mild discomfort, and have no diagnosed chronic digestive or immune conditions. As an unphased trial, it offers participants the opportunity to contribute to scientific understanding of digestive health.

Will I have to stop taking my current medications?

Yes, you will need to stop taking any medications and dietary supplements to participate in this trial.

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

Research has shown that the safety of probiotics and prebiotics, like those in the supplement under study, remains not fully understood. The U.S. Food and Drug Administration (FDA) does not regulate these supplements as strictly as medicines, allowing them to be sold with less safety testing.

Some studies have identified safety concerns, particularly with long-term use. In certain cases, probiotics have caused serious infections in vulnerable groups, such as premature babies. Additionally, prolonged use might increase inflammation in the body, which is undesirable.

While many people use these supplements without issues, the lack of strict regulation and comprehensive studies suggests potential risks. Prospective trial participants should consider these points and discuss them with a healthcare professional. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the dietary supplement with actives because it combines both prebiotics and probiotics to potentially improve overall health. Unlike typical supplements that may focus solely on either prebiotics or probiotics, this treatment offers a comprehensive approach by including both, which could enhance gut health more effectively. Additionally, the supplement is conveniently administered as a once-daily gummy, making it easy to incorporate into daily routines without the need for water or food. This user-friendly delivery method could encourage better adherence and, consequently, more consistent health benefits.

What evidence suggests that this dietary supplement could be effective for general health?

This trial will compare a dietary supplement containing active prebiotics and probiotics to a placebo. Research has shown that probiotics and prebiotics can improve overall health by supporting beneficial gut bacteria. Studies have found that probiotics aid digestion and may prevent certain infections, such as those in the stomach and lungs. They might also help with food allergies and dental health. While these areas appear promising, researchers are still learning about their effects on general health. Overall, these supplements are believed to boost the immune system and support better digestion. ^{3 5 6 7 8}

Published Research Related to This Trial

Pre- and probiotics have shown promising effects on gut health by maintaining a healthy gut microflora and influencing metabolic and immune mechanisms, but scientific proof of their benefits in humans is still lacking.

Certain clinical conditions, such as ulcerative colitis and antibiotic-induced diarrhea, have demonstrated therapeutic benefits from pre- and probiotics, suggesting potential for broader applications in gut health management.

Probiotics are beneficial microbial supplements that help improve gut health by balancing intestinal bacteria, and they can be effective in treating conditions like lactose intolerance and various types of diarrhea, including those caused by antibiotics and infections.

Clinical studies indicate that probiotics may also enhance immune function, prevent allergic diseases, and help manage inflammatory bowel diseases, suggesting their potential role in overall health and disease prevention.

Nutritional impact of pre- and probiotics as protective gastrointestinal organisms. Teitelbaum, JE., Walker, WA.[2006]

Prebiotics, particularly inulin-type fructans, are non-digestible ingredients that can selectively promote the growth of beneficial gut bacteria, which may improve health outcomes.

To truly understand the prebiotic effects, it's essential to study their impact on the entire gut microbiota in human subjects, rather than just focusing on individual bacteria in isolation.
