Fytexia releases scientific research on bioactive polyphenols in further exploring their benefits on human metabolism.

Promoted under the trademark Fiit-ns®, the efficacy of the formulation of extracts from grape, grapefruit, green tea, guarana, and black carrot, in association with vitamin B3, has been tested in 2 clinical trials. The most recent investigation was published in 2021 in the peer-reviewed journal Nutrients. This new article focuses on the improvement in both physical and mental components of the health-related quality of life:
“Sixteen Weeks of Supplementation with a Nutritional Quantity of a Diversity of Polyphenols from Foodstuff Extracts Improves the Health-Related Quality of Life of Overweight and Obese Volunteers: A Randomized, Double-Blind, Parallel Clinical Trial” by Cindy Romain et al, Nutrients 2021, 13(2), 492.

The randomized, double-blind, placebo-controlled study was conducted at the Research center of UCAM, Spain. The primary goal of the study was to investigate changes in the health-related quality of life (HR-QOL – assessed by the SF-36 validated questionnaire). 72 overweight and obese but otherwise healthy individuals were involved in the 16-week study.
Supplementation with 900 mg of Fiit-ns® daily was correlated with a HR-QOL improvement (+5.3%; p = 0.001), including enhanced perceived physical (+11.2%; p = 0.002) and mental health (+4.1%; p = 0.021) components, with bodily pain, vitality, and general health being the greatest contributors.
Body weight of the supplemented group significant decreased by 1.3 kg (p = 0.013). Body fat mass significantly decreased (1.2 kg; p = 0.033), mainly within the trunk area (1.0 kg; p = 0.002). Consequently, the waist size significantly decreased by 1.1 cm (p = 0.017), lowering the Index of Central Obesity by 1.3% (p = 0.018).
Supplementation with Fiit-ns® induced a significantly increased engagement in physical activity (+1308Met-min [Metabolic Equivalent Task minutes]/week; p = 0.050) compared to the placebo group.
Fiit-ns® is proven to help in activating a virtuous circle to reach a better quality of life.
Fiit-ns® is now supported by 2 published clinical studies demonstrating the benefits of polyphenol-rich dietary supplementation. Fiit-ns® is suitable for tablets, capsules, sachets, stick packs, and functional beverages at a daily dosage of 900mg/day.
