Discover the Benefits of Life Changing Hormones
Hormones can be categorized into three distinct groups according to their chemical composition. The three types of hormones are steroid hormones, peptide hormones, and amino acid derivatives. The different types of hormones will have different mechanisms of action due to their distinct chemical properties.

Amine hormones are derived from the amino acid tyrosine and include adrenaline, thyroxin and triiodothyronine.
Amine hormones do not all share identical properties and have properties common to both peptide and steroid hormones.
Steroid hormones are lipophilic (fat-loving) – meaning they can freely diffuse across the plasma membrane of a cell.
They bind to receptors in either the cytoplasm or nucleus of the target cell, to form an active receptor-hormone complex.
This activated complex will move into the nucleus and bind directly to DNA, acting as a transcription factor for gene expression.
Peptide hormones are hydrophylic and lipophobic (fat-hating) – meaning they cannot freely cross the plasma membrane.
They bind to receptors on the surface of the cell, which are typically coupled to internally anchored proteins (e.g. G proteins)
The receptor complex activates a series of intracellular molecules called second messengers, which initiate cell activity.
This process is called signal transduction, because the external signal (hormone) is transduced via internal intermediaries.
The use of second messengers enables the amplification of the initial signal (as more molecules are activated).
There is confusion over exactly what bioidentical hormones are and their use and effect on the body. Bioidentical hormones are chemically and functionally identical to human hormones. The body has the necessary enzymes to break down and metabolize these hormones.
Bioidentical hormones are designed to produce the same responses in the body as hormones made by the human body. Restoring and balancing hormones with Bioidentical hormones is an individualized approach to hormone replacement. Bioidentical hormones are custom made for each patient.

Menopause and Andropause
As they age, women eventually lose their fertility naturally. Menopause, the physical change that marks the end of a woman’s fertility results in irregular periods as the ovaries stop producing eggs, as well as reduced production of the hormones estrogen and progesterone.
Andropause, a less well-known physical change in aging men is similarly characterized by a decline in androgen or sex hormone levels. While fertility doesn’t necessarily end for men, andropausal men experience reduced sexual drive and function.
