Glands form part of the body’s endocrine system; secreting a wide range of essential hormones directly into the bloodstream, including oestrogen, testosterone, insulin, thyroxine, cortisol and DHEA to name just a few. Collectively, these hormones control vital body functions such as metabolism, immunity, growth, reproduction and sexual development. The endocrine system is finely tuned to produce and distribute optimal levels of hormones throughout the body; too much or too little of a certain hormone can have effects throughout the body and can lead to a range of different health problems. Some examples of glands include thyroid, thymus, adrenal, pancreas, ovary and prostate. Although not technically glands, other tissues and structures are utilised in brand ‘glandular’ product ranges for additional health benefits.
