Microalgae Extract for Anxiety and Gut Health
(Tetrasol Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores whether a microalgae extract dietary supplement can aid anxiety and gut health. Researchers aim to determine if daily intake of this supplement improves symptoms such as stomach discomfort and stress levels. Participants will receive either the microalgae supplement or a placebo (a pill with no active ingredient) to compare effects. The trial seeks adults who frequently experience mild to moderate stomach issues. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this new treatment.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications, but you cannot participate if you regularly use NSAIDs (a type of pain reliever) or MAO inhibitors (a type of antidepressant).
Is there any evidence suggesting that this treatment is likely to be safe for humans?
Research has shown that taking microalgae extract daily is generally safe and easy for most people to handle. In one study, participants used the supplement for four weeks without any major side effects. This suggests that the microalgae extract, similar to the one tested in this trial, is likely safe for people. This trial is in the early stages and primarily focuses on safety. While no serious problems have emerged, the trial will help confirm how well people can tolerate the extract.12345
Why do researchers think this study treatment might be promising?
Unlike standard treatments for anxiety and gut health, which often involve pharmaceuticals like SSRIs or probiotics, this new approach uses microalgae extract. Researchers are excited about this treatment because it harnesses a natural product called Tetrasol extract, which might offer benefits with potentially fewer side effects. This extract is packed with nutrients and bioactive compounds, possibly offering a dual benefit of calming anxiety while promoting gut health. Plus, the use of a natural supplement could appeal to those looking for a holistic alternative to traditional medications.
What evidence suggests that this treatment might be an effective treatment for anxiety and gut health?
Research has shown that the microalgae extract, Tetrasol, might improve gut health and reduce anxiety. In this trial, participants will receive either microalgae extract capsules or a placebo. One study found that people who took Tetrasol daily for four weeks experienced fewer stomach problems. The supplement proved to be safe and easy to take. Early findings suggest that this microalgae extract might also aid mental health by reducing stress and anxiety. While more research is needed, these early results are promising for those seeking to support their gut and mental well-being.12346
