I am a 64 year old female. I have had type 2 diabetes for 25 years and have it controlled by diet and exersice. Recently, I have experienced hair loss, lethargy, a slight weight gain, and my excema has returned. I believe I have a zinc deficiency and would like to take a OTC supplement. If this doesn t work I promise to consult with my primary care physician ...but want to see if I can handle this on my own first.
