Nutritional Supplementation on Physiological and Metabolic Markers in Females

The goal of this clinical trial is to learn if a 12-week nutritional supplement can result in significant changes in the body composition of 38-55-year-old females. The main questions it aims to answer are: * Does a 12-week nutritional supplementation with myo-inositol, berberine, cinnamon, and chromium lead to significant changes in body composition (e.g. body mass index, body fat composition) in females aged 38-55 compared to placebo? * Does a 12-week nutritional supplementation with myo-inositol, berberine, cinnamon, and chromium lead to significant changes in small molecules (metabolites) in plasma and urine, menopause-related symptoms, and physical performance (e.g. grip strength) in females aged 38-55 compared to placebo? Researchers will compare the nutritional supplement to a placebo (a look-alike substance that contains no nutritional supplement) to see if the intervention works to change body composition in females aged 38-55. Participants will: * Sign a consent form before any procedures begin * Attend two visits to the clinical research facility at Southampton General Hospital over 12 weeks. * Fast before visit's and provide blood and urine samples at each visit * Undergo measurements at each visit, including waist and hip circumferences, grip and leg strength, and body composition. * Complete questionnaires about general health, menopause-related changes, alcohol consumption, physical activity, and diet. * Take 1 capsule 3 times a day at the onset of a meal (once in the morning, once at midday, and once in the evening) for the first 10 days. * Take 3 capsules 3 times a day at the onset of a meal (once in the morning, once at midday, and once in the evening) from day 11 to day 84. * Record supplement intake in a daily compliance diary during the study
