Inositol, often referred to as vitamin B8, is a compound found in the body and many foods, gaining attention for its potential benefits in managing conditions like polycystic ovary syndrome (PCOS) and aiding weight loss. Experts highlight its role as an insulin sensitizer, which can improve hormonal balance, regulate menstrual cycles, and enhance ovulation. Although inositol is not a traditional fat-burning supplement, it may support weight management by reducing insulin spikes and controlling sugar cravings. The inositol market is expected to grow significantly, valued at approximately $160-170 million in 2024-2025, driven by increasing cases of obesity and hormonal disorders. While generally safe, some individuals may experience mild gastrointestinal side effects, and long-term use should be guided by a healthcare provider. Inositol can be beneficial for women with PCOS, insulin resistance, or irregular menstrual cycles, but healthy individuals may not need supplementation if their diet is balanced.
