Improving Sleep Quality for Healthy Population Experiencing Difficulty Falling Asleep or Staying Asleep

Complete Pre-Screen Online

Do you have difficulty falling asleep or Staying Asleep? You are not alone.

Sleep is a basic function that humans need to function properly. Over 25% of people in the North America have report issues falling asleep or staying asleep in North America and over 34% having experienced sleep disturbances in the last 7 days.

This has created a demand for sleep aids for many adults on a regular basis. The recent pandemic has caused an increase in stress and anxiety in the somewhat healthy adult population, exacerbating sleep issues and irregularity and a good night’s sleep. Prescription sleep aids have been prescribed at increasing levels in the last 2 years and well they do assist with getting good night’s sleep long term use can cause serious adverse side effects such as diarrhea, memory impairment and fatigue. Due to these side effects many look to a more natural solution to sleep disruption such as melatonin.


This study is looking at the product Maizinol that is created from the leaves of Zea Mays L (corn) which has a substance 6-Methoxybenzoxazolinone which is structurally like Melatonin. Maizinol has previously been proven to improve mood in moderately anxious/depressed individuals with no serious adverse events or clinical vital signs. We are looking into the benefits of Maizinol on improving sleep quality for individuals having sleep disturbances

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?
