Effect of daily consumption of whole fruit feijoa powder (Feiolix) on metabolic profile: A Randomised Controlled Trial

The study examined the effects of feijoa powder (Feiolix) on metabolic parameters in adults with prediabetes and overweight. A total of 39 participants aged 21-65 years were divided into three groups: low-dose Feiolix (300 mg/day), high-dose Feiolix (1,150 mg/day), or placebo. After 12 weeks, HbA1c decreased by 0.5% in the high-dose group and 0.4% in the low-dose group, both significantly greater than placebo. Feiolix significantly reduced fasting glucose, insulin, total cholesterol, and LDL-cholesterol compared to placebo. The high dose also reduced body weight and BMI and prevented triglyceride increase. No adverse effects were reported. The results suggest the potential of Feiolix supplementation to improve metabolic health.
