A recent study found that a polyphenol-rich ingredient composed of extracts of grape, grapefruit, green tea, guarana, and black carrot, in association with vitamin B3 (Fiit-ns from Fytexia) supported the quality of life of overweight subjects.

A recent study1 found that a polyphenol-rich ingredient composed of extracts of grape, grapefruit, green tea, guarana, and black carrot, in association with vitamin B3 (Fiit-ns from Fytexia; Verdres, France) supported the quality of life of overweight subjects. In the randomized, double-blind, placebo-controlled study, 72 overweight and obese subjects were assigned to receive 900 mg/day of the polyphenol-rich ingredient or placebo for 16 weeks. Health-related quality of life was the primary outcome, but daily physical mobility, and dietary intakes were monitored and recorded as well.

Results showed that, compared to placebo subjects taking the polyphenol-rich ingredient experienced significant improvements in health-related quality of life (+5.3%), including enhanced physical and mental health components, with bodily pain, vitality, and general health being the greatest contributors. Supplementation was also associated with significant reductions in body fat mass, as well as significant increases in physical activity.
