Complete Pre-Screen Online

Investigating a ginseng-based supplement on cancer-related fatigue in adults who have received cancer treatment.


Dealing with cancer is exhausting. Fatigue is one of the most common symptoms of cancer as well as one of the most common side effects from cancer treatments.  Cancer-related fatigue (is more than just being tired at the end of the day, it is the inability to get out of bed, the lack of motivation to do anything and just an overwhelming tiredness that affects you mentally, emotionally, and physically.

Ginseng has been shown to have antioxidant and anti-inflammatory effects.  Ginseng’s ability to prevent abnormal cell production and growth give it the potential to have anti-cancer benefits by regulating the normal cell growth cycle. Due to Ginseng’s many health benefits, it has been suggested that Ginseng may have a beneficial effect for cancer related fatigue.

In this Health Canada and Institutional Review Board approved study, adults between the ages of 18-65 will be provided with specialized ginseng extract supplement Redsenol-1 that has been suggested to have a role in decreasing CRF in previous studies. You will be instructed to take the Redsenol-1 Supplement regularly over a period of 12 weeks as well as provide measurements on your fatigue levels, vitals, and blood draw at clinic visits.

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?
