Ana was 43 and had always been bubbly and active with tons of energy and a quick mind. She kept up with her health checks, had normal iron levels and no concern with her thyroid, and she ate a nutrient rich diet including some red meat rich in iron and zinc. She was working five days per week with regular hours and enjoyed her job. But now she was tired and could hardly get through the afternoon. She had lost her lust for life and even her evening social tennis was in the past. Ana’s doctor told her it was age related but a physical well-being test and fitness assessment did not indicate this at all and in fact gauged her fitness as that of a 35 year old. She was depressed and absolutely stumped as to what had changed to make her feel so low.
