When the body is in motion, a person can do many things like exercising or just enjoying the day out. This is due to the hormones that are doing their job and making sure that each system is doing what they are supposed to do. Hormones are made in the endocrine system and are secreted out through the adrenal glands. when there are unwanted pathogens are inside the body and causing the hormone levels to overproduce it can cause the body to go haywire. In this three-part series, we will be discussing about the hormone pregnenolone and its functions as well as seeing how melatonin can affect the body’s hormones. Part 1 discusses what happens when the female body when it goes through menopause and how estrogen and progesterone are utilized in the body, and what function do they provide to the female body. In Part 2, we discussed about the symptoms of DHEA dysfunction and the relationship between female hormones and insulin. Over the last decade, many of our patients have asked complex and insightful questions about hormone replacement therapies. By referring patients to qualified and skilled providers who specialized in hormone wellness services and we advise our patients to appropriately refer to our associated medical providers based on their examination. We find that education is the key when asking valuable questions to our providers. Dr. Jimenez DC provides this information as an educational service only. Disclaimer

What is Hormone Replacement Therapy?

Hormone replacement therapy or HRT actually can help supplement menopausal women replenish their hormone levels. Menopause is when a woman starts to lose their hormone levels naturally and it can range from 35 years of age through 55 years of age. So with hormonal replacement therapy, it can help the body replenish the lost hormones and can provide beneficial results. For the female body, HRT can help regulate and repair hormonal growth in females.

The Hormone Pregnenolone



The hormone pregnenolone is the precursor to DHEA, estrogen, progesterone, and testosterone. It is found naturally in the body and is made from the body’s cholesterol. However, if a person has very low cholesterol that is below 140, their body cannot produce pregnenolone effectively but can take supplements that do contain pregnenolone to replenish the low levels. Sadly like all hormones, it does naturally decline due to age, and when individuals are at the age of 75, their pregnenolone hormone levels decline to 65%.


The Functions Of Pregnenolone

There are many functions that pregnenolone can offer to the body. It can help regulate the balance between excitation and inhibition in the nervous system and can increase the resistance to stress. If a person is feeling a bit low on energy, pregnenolone can help give the body a bit of boost energy both physically and mentally. Pregnenolone can even help block the production of acid-forming compounds that are inhibiting the body. Other beneficial function that pregnenolone can provide includes:

  • Modulates the neurotransmitter GABA
  • Helps to repair nerve damage
  • Promotes mood elevation
  • Improves sleep
  • Enhances acetylcholine transmission
  • Modulates NMDA receptors
    • Regulates pain control, learning, memory, and alertness
  • Is anti-inflammatory


The Symptoms Of Pregnenolone Deficiency

When the body doesn’t produce enough pregnenolone it can cause the body to go haywire. When that happens, this is known as pregnenolone deficiency. Some of the causes of low levels of pregnenolone can include:

  • Eating too many saturated fats and trans-fats
  • Very low cholesterol levels
  • Hypothyroidism
  • Pituitary tumor
  • Having a severe illness
    • Pregnenolone will make more cortisol and less of the other hormones to help the body deal with stress.

When these causes are affecting the body and the individual has pregnenolone deficiency it can cause the individual’s body to be dysfunctional and can cause harm if it is not taken care of. Some of the symptoms of pregnenolone deficiency include:

How Pregnenolone Is Used In Treatments?

Since pregnenolone is the precursor to estrogen and all the other female hormones, it is amazing that it is a potential candidate for antiproliferative hormones to ovarian cancer and other female reproductive diseases. Since pregnenolone is anti-inflammatory it can help dampen the causes of inflammatory diseases that can harm the body. Some of the treatments that pregnenolone can provide are:




If there is one thing that can help a person feel at ease and make their bodies relax, it is melatonin. It is the one hormone that plays a huge role when it comes to sleep and it is produced by the pineal gland at night. Surprisingly though, it is made from tryptophan which is also used to make serotonin, and if the melatonin production goes up inside the body, the production of serotonin goes down. This can also go in reverse if a person is eating too many high glycemic index carbohydrates, melatonin production goes down and the production of serotonin goes up. And if a person is taking B vitamins, the body can convert those B vitamins to melatonin from tryptophan.


The Many Functions Of Melatonin

Even though melatonin is used for a better night’s sleep, there are many other beneficial properties that melatonin can provide to the body. Melatonin can actually affect the release of sex hormones in the body and can help block the estrogen hormone from binding to receptor sites in the body. Melatonin can even help with decreasing cortisol levels by making the body relax and release all the tension that the individual was harboring. Other beneficial properties that melatonin can offer are:

  • Aids the immune system
  • Acts as an antioxidant
  • Helps balance the stress response
  • Helps prevent cancer
  • Improves mood
  • Increases the action of benzodiazepines
  • Stimulates the parathyroid gland
  • Stimulates the production of growth hormone
  • Cardio-protection
  • Protects against GERD


Melatonin & Cardioprotection

Since melatonin is produced by the pineal gland, the biological effect of combating oxidative stress is remarkable. Studies have shown that melatonin can regulate the immune and inflammatory responses in the body, enhance mitochondrial function, and plays a critical role in protecting cardiomyocytes from infarction. Melatonin has been shown to reduce hypoxia and prevent reoxygenation-induced damage
in patients with cardiac ischemia and ischemic stroke.


Melatonin & Insulin

Melatonin is necessary for the proper synthesis, secretion, and action of insulin and acts by regulating GLUT4 expression and/or triggering, via its G‐protein‐coupled membrane receptors, the phosphorylation of the insulin receptor and its intracellular substrates mobilizing the insulin‐
signaling pathway. Melatonin is a powerful chronobiotic meaning that it helps regulate the body’s internal clock.

Furthermore, melatonin is responsible for the establishment of an adequate energy balance by
regulating energy flow to and from the stores and directly regulating the energy expenditure through the
activation of brown adipose tissue and participating in the browning process of white adipose tissue. The reduction in melatonin production, with aging, shift‐work, or illuminated environments during the
night, induces insulin resistance, glucose intolerance, sleep disturbance, and metabolic circadian changes which leads to weight gain.


Melatonin & Alzheimer’s Disease

Some symptoms of decreased melatonin are also common to patients with Alzheimer’s
disease. This can include:

  • Disruption of circadian rhythm
  • Mood changes
  • Delirium

One medical trial showed that melatonin levels in the CSF in patients over the age of
80 were ½ the level of younger/healthier patients and patients in this study with Alzheimer’s,
the disease had even lower levels which were 1/5 of those in young healthy people. Melatonin has even shown patients beneficial properties when diagnosed with early Alzheimer’s disease. 


Melatonin & Parkinson’s Disease

Melatonin replacement has been shown to decrease the risk of developing Parkinson’s disease. Animal trials have shown that melatonin can prevent and to some extent may even help reverse the motor and behavior changes that are associated with Parkinson’s disease. In Parkinson’s disease, there is an
accumulation of a protein called alpha-synuclein. Surprisingly melatonin supplementation can help prevent the production of alpha-synuclein in the brain cells and attacks them so that way it can be more available to be removed from the body.


All in all, hormones play the most functional and important role in the body. If there are unwanted pathogens that are affecting the body and causing the hormone levels to rise, it can cause the body to go haywire and be prone to chronic illnesses. So it is important that the hormone levels are normal and functional for people to live a healthy life.
