The endocrine system is composed of all the essential endocrinal glands such as the hypothalamus, thyroid, pituitary, parathyroid, adrenal, and reproductive glands.  These glands secrete hormones that maintain healthy functioning of all bodily systems including regulating mood, growth and development, and sexual/reproductive function.   Proper nutrients, targeted to support endocrine health, can help provide the essential building blocks for proper functioning.
