What You Need to Know Before You Apply

What is the purpose of this trial?

This trial examines whether a special postbiotic blend, called Postbiotic Active Lifestyle Blend, can reduce exercise-induced stress and boost performance. Participants will take either this postbiotic supplement or a placebo that looks identical but contains no active ingredients. The trial targets healthy adults who exercise regularly, at least 2 to 5 times a week. Participants should not have significant ongoing medical issues or use antibiotics, probiotics, or nicotine products. As an unphased trial, it offers participants the opportunity to contribute to innovative research that could enhance exercise recovery and performance.

Will I have to stop taking my current medications?

The trial does not clearly state if you need to stop taking your current medications. However, if you have recently changed your dosage of certain medications like statins, hypertension, or psychiatric drugs, you may not be eligible to participate.

Is there any evidence suggesting that the Postbiotic Active Lifestyle Blend is safe?

Research has shown that postbiotics, such as the Postbiotic Active Lifestyle Blend, are generally safe for people. Postbiotics are products derived from heat-treated bacteria. They are considered safer than probiotics because they do not contain live bacteria, eliminating the risk of antibiotic resistance. Recent studies suggest that postbiotics can improve health without causing serious side effects.

While specific safety information for the Postbiotic Active Lifestyle Blend remains limited, the overall safety of postbiotics appears promising. They are easy to produce and typically have a long shelf life, enhancing their safety and usefulness. ^{1 2 3 4 5}

Why are researchers excited about this trial?

The Postbiotic Active Lifestyle Blend is unique because it leverages a heat-treated blend of bacterial strains to potentially enhance exercise performance. Unlike traditional supplements that often focus on nutrients or vitamins, this postbiotic approach targets the gut microbiome, which researchers believe could play a significant role in physical performance. By focusing on gut health, this treatment could offer a novel way to boost stamina and recovery, setting it apart from existing options like protein powders and energy drinks. Researchers are excited about its potential to optimize exercise outcomes through an innovative mechanism that complements the body's natural processes.

What evidence suggests that the Postbiotic Active Lifestyle Blend could be effective for exercise performance?

This trial will evaluate the effects of the Postbiotic Active Lifestyle Blend on exercise performance. Studies have shown that postbiotic supplements can enhance exercise performance. Early evidence suggests that postbiotics may reduce tiredness and boost readiness, which is crucial for athletes. Some research indicates they can improve mood and reduce stress-related issues like anxiety and depression during exercise. Additionally, postbiotics may help manage inflammation, which often occurs with intense physical activity. While research on humans is still developing, these initial findings suggest that postbiotics could support better exercise results. Participants in this trial will receive either the active Postbiotic Active Lifestyle Blend or a placebo. ^{1 3 6 7 8}

What Are the Treatments Tested in This Trial?

Interventions

• Postbiotic Active Lifestyle Blend

Trial Overview

Participants will be randomly assigned to receive either a placebo or an active postbiotic blend. The study aims to determine if the postbiotic reduces oxidative stress and improves exercise performance in a double-blind setup where neither participants nor researchers know who receives what until the end.

How Is the Trial Designed?

Group I: Postbiotic Active Lifestyle Blend Experimental Treatment 1 Intervention

Participants in this arm will receive the active Postbiotic Active Lifestyle Blend supplement, which contains a heat-treated blend of bacterial strains

Group II: Placebo Placebo Group 1 Intervention

Participants in this arm will receive a placebo capsule that matches the appearance and dosage of the active blend.

Published Research Related to This Trial

A systematic review of 1,204 participants found that pre-, pro-, and syn-biotic supplements did not significantly improve gastrointestinal permeability or symptoms at rest or during exercise, indicating limited efficacy for these interventions.

While prebiotic supplementation increased certain beneficial gut bacteria and short-chain fatty acids, probiotics mainly boosted the specific strains given without affecting overall gastrointestinal health markers, suggesting a need for more comprehensive studies with validated biomarkers.
