Assessing hormones and neurotransmitters, such as progesterone and GABA, is crucial to women’s neuroendocrine health. Testing and addressing imbalances can help promote women’s sense of well-being and overall quality of life.

Progesterone and Women’s Health

Throughout life, women experience fluctuating hormone levels. Progesterone and estrogen rise and fall during the menstrual cycle, potentially contributing to mood swings and PMS concerns.1,8 As women move towards menopause, progesterone levels generally start to decline. 10

Progesterone and GABA

Changes in progesterone levels can alter one’s mood and sense of well-being. This is because allopregnanolone, the progesterone metabolite, is a GABA-A receptor agonist. This means that allopregnanolone binds to GABA-A receptors.4,9 Thus, with higher progesterone levels, GABA function increases. As the main inhibitory neurotransmitter, GABA plays roles in promoting calmness, good mood, and sleep.3,5,7

Low Progesterone and its Effects on GABA

Decreased levels of progesterone may be linked with low GABA function. Insufficient GABA has been associated with anxiety, depression, and sleep issues. Poor GABA function may also allow for increased excitatory neurotransmitter activity, which often results in poor sleep, anxiety, and other mood concerns.7 These issues are common in and around menopause.11

Progesterone and Brain Health

Progesterone may also be neuroprotective.6,12 Studies have shown progesterone to:

  • Increase brain-derived neurotrophic factor (BDNF), which increases nerve and brain repair13
  • Increase myelination (protective sheaths of nerves)12
  • Reduce glutamate response2
  • Limit cellular necrosis/apoptosis6,12

Addressing Imbalances

It is important for practitioners to consider progesterone and GABA function, particularly in women around menopausal age with anxiety, depression, or sleep concerns. Assessing sex hormones and neurotransmitter levels can help guide the practitioner to appropriate intervention, such as bio-identical hormone replacement and neurotransmitter precursor and cofactor support.1,12

“Educating Sanesco’s clients is the culmination of a life’s work.” Beginning when she left the hospital environment to manage a functional laboratory, Genova Diagnostics (formerly Great Smokies Laboratories) in 1987, Dr. Connie Shoemaker has continued to increase her knowledge of herbs and biochemistry as a journey of love. With her bachelor’s in science from Western Carolina University, she had worked in hospital laboratories for the first twelve years of her career. Then, personal health challenges led her to discover a new approach to her health and a determination to share it with others. In 1991, she began teaching and educating innovative practitioners in the U.S. and internationally as a manager of marketing, sales, and customer service.

The addition of her Doctor of Naturopathy degree to her existing knowledge base expanded her knowledge and her respect for a more natural approach to healing through balance. At Sanesco, she initially served to oversee technical development of products and services.

Now, she educates Sanesco’s clients on application of the CSM™ model for their specific patients and how to integrate the CSM™ model with other modalities they offer in their practice. In her personal life, Connie educates private clients on various health topics.
