Complete Pre-Screen Online

Investigating the efficacy of AlphaWave L-Theanine on adults who experience moderate stress

We all experience stress sometimes. Stress is normal and healthy for our bodies to experience occasionally, however, when a person experiences stress for prolonged periods of time, it can lead to negative health consequences. Due to extreme global issues such as Covid-19, it has been predicted that the general population will experience negative social effects and an increase in negative stress levels for years to come. We need strategies to manage and reduce the increased levels of stress in our lives. Exercising, deep breathing, meditation and cessation of tobacco and nicotine consumption are all great options but require compliance, which can be difficult for some. Looking for sustainable solutions to reduce this burden is important. L-Theanine may be a solution.


L-Theanine is an amino acid found in green tea and is known to have calming effects. Human studies have shown a decrease in anxiety with L-Theanine supplementation. These studies were conducted over short periods of time. Lengthier studies are required to determine the sustainability of using L-theanine to reduce stress levels in the long term.

Clinical Trials FAQ

What is a clinical trial?

Clinical trials on natural products are research studies in which people help doctors and researchers test out claims that are made on health and wellness products. Having scientific evidence to back up the claims on natural products helps give consumers like you confidence that the products you are buying are safe and effective.

Who conducts a clinical trial?

At KGK Science, our studies are overseen by medical doctors and a proficient team of nutritionists and clinical coordinators who will guide you through each step of your participant experience.

Who is eligible to participate in a clinical trial?

Each study has its own guidelines called “eligibility criteria”. To ensure the strongest results, researchers want study participants to be alike in key ways. Examples of eligibility criteria for a trial might be age, gender, weight/height ratio and/or your previous medical history.

Will it cost me any money to join a clinical trial?

No, there are no out of pocket expenses for you to join a clinical trial other than your travel expenses to and from the clinic site. KGK Science provides you with all the necessary requirements to participate, including parking fees AND you are compensated for your time.

How long do your studies last?

Some studies are only one full day, and others may run for a few weeks or months. The schedule of visits and duration is discussed with you prior to you making a commitment to join the study.

Is my participation confidential?

All records relating to your identity and study participation are confidential as per the Personal Information Protection Act (PIPA), the Health and Information Protection Act (HIPA) and the Electronic Documents Act.

How do I sign up?

How do I know if I qualify?

After you contact us or fill out your pre-screen survey, we will arrange a time to go through a telephone screening with you, asking you more specific qualifying questions and informing you of the details of the study. If you are eligible, you may be asked to come to our clinic for a personal screening visit. Once we complete the screening visit, if you qualify you will be contacted to enroll in the study.

What are the other requirements?

Some studies require you to keep an electronic diary of your food intake or certain activities throughout the day. KGK provides access to a free web app to record your entries and you are paid for this additional time off site.

Are clinical trials safe?

Researchers, doctors, and other health professionals conduct research studies according to strict rules set by the Food and Drug Administration (FDA), Health Canada and other regulatory agencies. These rules are to protect clinical trial participants and to make sure they are treated as conscientiously as possible. Research studies are also overseen by medical ethics groups to ensure that study participants are treated correctly.

Can I leave a research study once it has begun?

Yes. You are free to leave the trial at any time. If you do decide to leave, you should let the research team know and tell them why you are leaving the study. Early termination measures will be done to ensure your safe exit from the study.
