"For women over 35, insulin resistance is one of the primary drivers of visceral fat storage, particularly in the deep abdominal region. When Estrogen Receptor Alpha (ERα) signaling declines, GLUT4 glucose transporters in skeletal muscle downregulate, meaning your body requires higher insulin spikes to clear blood glucose. The supplements below are evaluated on their clinical trial efficacy in improving GLUT4 translocation, lowering fasting insulin, and matching target clinical trial dosages."
