My guest is Kyle Gillett, MD, a dual board-certified physician in family medicine and obesity medicine and an expert in optimizing hormone levels to improve overall health. We discuss how to optimize male hormones using a range of nutritional and behavioral tools, exercise and supplementation (including tongkat ali, fadogia agrestis, creatine, peptides and more). We explain how puberty and aging affect hormone levels, how to use bloodwork to monitor hormone levels, how hormone health impacts fertility, libido, hair loss and prostate health and describe behaviors that negatively impact testosterone levels. We also discuss how to approach prescription hormone therapies, including which biomarkers to monitor when using these approaches and how to optimize synergistic hormones (e.g., growth hormone and thyroid hormone) to support complete hormone health safely and rationally. Dr. Gillett offers numerous actionable tools that can be tailored to specific goals and age ranges to attain and maintain optimal levels of male hormones for overall health, well-being and longevity.
