Our bodies are complex and have numerous systems that regulate growth, development, metabolism, and tissue function. However, as we age, certain biological and physiological changes, as well as environmental factors, diet, and lifestyle, affect these systems, interfering with the secretion, production, and catabolism of hormones and chemicals that we need to function optimally. By supplementing with substances like berberine, you can provide your body with the support it needs to keep those systems functioning as they should.
