Morley speaks with Katie about thyroid health, retinol, magnesium and the real story of aging. Many of us are told to supplement with Iron and vitamin D, but Morley delves into why that might not be a good idea. He expands on the previous appearance on Wellness Mama to go even deeper on the importance of copper and vitamin A (plus other nutrients) for overall health and energy. He also covers hair testing, and what to really look for when doing this.
