Prolactin is a pituitary hormone that plays a pivotal role in a variety of reproductive functions. If you are interested in the latest research on natural supplements and hormones, consider subscribing to a free natural medicine newsletter sent by email.
Influence on metabolism
Prolactin affects metabolic homeostasis by regulating key enzymes and transporters that are associated with glucose and lipid metabolism in several target organs. In the lactating mammary gland, prolactin increases the production of milk proteins, lactose and lipids. In adipose tissue, it generally suppresses lipid storage and adipokine release. Prolactin supports the growth of pancreatic islets, stimulates insulin secretion and increases citrate production in the prostate. A specific case is made for prolactin in the human breast and adipose tissue, where it acts as a circulating hormone and an autocrine or paracrine factor. Although the overall effects of prolactin on body composition are modest and species specific, prolactin might be involved in the manifestation of insulin resistance.
High prolactin Level
Hyperprolactinemia is a common condition that can result from a number of
causes; including use of medications and hypothyroidism, as well as
pituitary disorders. Depending on the cause and consequences of
hyperprolactinemia, selected patients require specific treatment. The
underlying cause of hyperprolactinemia, sex, age and reproductive status
must be considered. Management of this condition depends heavily on the
cause and on the effects it has on the patient. The definition of the
hyperprolactinemia is not uniformed, and in various clinical settings
various criteria of this status are used. In the identification of
hyperprolactinemia not only simple measurements of the prolactin serum
level are used, the dynamic tests with the use of dopamine antagonists
have a special role as well. Neither the measurement of the serum
prolactin level, nor dynamic tests with dopamine antagonists are able to
determine the presence of macroprolactin molecules in the serum, and this
can lead clinicians to establish the false diagnosis of hyperprolactinemia.
One cause of a high prolactin level, particularly in women, is treatment with Prozac or other SSRI drugs.
How to lower
prolactin levels naturally
Trop Doct. 2015. Jasmine flower extract lowers prolactin. Antipsychotic drugs frequently cause amenorrhoea and galactorrhoea. Jasmine flowers used topically were as effective as oral Bromocriptine in suppressing puerperal lactation. This study aims to evaluate the efficacy and safety of intranasal jasmine flower extract (JFE) to reduce prolactin levels of patients on stable doses of antipsychotic drugs. This is a randomized, double blind, crossover clinical trial. An aqueous-ethanol extract of jasmine flowers was prepared and used as nasal drops. A decrease in serum prolactin of ≥25 ng/mL was considered a significant response. Ten out of 35 women had a significant drop in the serum prolactin while on the JFE. The non-responders to JFE were on higher doses of antipsychotic drugs. The main side effect was a transient and mild burning sensation in the nose. A cost analysis favoured jasmine flower extract over dopamine agonists.
Bright light exposure, especially in the morning, stimulates the pituitary gland to produce leutinizing hormone. This results in increased levels of testosterone and inhibition of melatonin production by the pineal gland. Decreased plasma melatonin is thought to lead to reduced serum prolactin – and high prolactin has been linked to sexual dysfunction.
Prolactin and Multiple sclerosis
MS can go into remission when women are pregnant. A study involving mice showed that prolactin triggers production of myelin, a fatty substance that insulates nerve cells in the brain and spinal cord. In multiple sclerosis, the immune system, which normally protects the body, is believed to attack the myelin that coats nerve cells, causing a worsening loss of sensation and movement that can range from relatively minor to profoundly disabling. Perhaps future research will find prolactin could be used in people to repair damage caused by MS and improve their symptoms. Prolactin increases in the body during pregnancy and is involved in stimulating milk production among other things.
Prolactin as one of the reproductive hormones
The three reproductive hormones (leutinizing hormone, follicle-stimulating hormone, prolactin). Reproductive hormones are probably the most commonly measured hormones after the thyroid hormones.
Human reproductive evolution, involving a complex interaction of the hypothalamic-pituitary-ovarian axis, the release of pulsatile and threshold concentrations of gonadotrophins and positive and negative feedback systems, has ensured the release of a single viable egg and functioning corpora lutea in the natural menstrual cycle.
Depression medications and their influence
Clin Psychopharmacol Neurosci. 2015. Emerging Hyperprolactinemic Galactorrhea in Obsessive Compulsive Disorder with a Stable Dose of Fluoxetine. While fluoxetine is a frequently prescribed selective serotonin reuptake inhibitor (SSRI), with few major side-effects; altered serotonergic transmissions in hypothalamic pathways might lead to a distressing, and often embarrassing, manifestation of galactorrhea by altering prolactin release in those on Prozac. We report here a case of Prozac induced hyperprolactinemic galactorrhea developing late into treatment on a stable regimen, who responded well to subsequent replacement with sertraline. Based on present finding, we suggest that while SSRIs may share similar mechanisms of action, there exist individual differences in their effects on prolactin secretion pathways.
Schizophr Res Treatment. 2013. Effects of Antipsychotics on Prolactin Levels and Women's Menstruation. Typical and atypical antipsychotic agent is currently used for treatment in the majority of patients with psychotic disorders. The aim of this review is to assess antipsychotic induced hyperprolactinaemia and the following menstrual dysfunction that affects fertility, quality of life, and therapeutic compliance of women. Method. For this purpose, Medline, PsychInfo, Cochrane library, and Scopus databases were accessed, with a focus on the publication dates between 1954 and 2012. Research of references was also performed and 78 studies were retrieved and used for the needs of this review. Results. A summary of several antipsychotics as well as frequency rates and data on hyperprolactinaemia and menstrual disorders for different agent is presented. Conclusion. Diverse prevalence rates of hyperprolactinaemia and menstrual abnormalities have been found about each medication among different studies. Menstruation plays an important role for women, thus, understanding, careful assessment, and management of hyperprolactinaemia could enhance their lives, especially when dealing with women that suffer from a psychotic disorder.
Cancer. 2016. Prolactin and breast cancer: The need to avoid undertreatment of serious psychiatric illnesses in breast cancer patients: A review. Hyperprolactinemia, defined as a sustained elevation of prolactin (PRL) levels greater than 530 mIU/L in women and greater than 424 mIU/L in men, has been implicated for a long time in breast cancer etiology and prognosis. Elevated PRL values (approximately 2-3 times higher than the reference values) are a common adverse effect of antipsychotic medications, especially with first-generation drugs, and most antipsychotics carry a standard warning regarding PRL elevations on their US product labels.
Do you sell a tested herbal product for suppressing prolactin?
I am not aware of an herb or such a natural product specifically tested for prolactin suppression.
Does the supplement
LJ100, an extract of tongkat ali, may influence hormone levels but it is not clear what kind of influence it has.
Wondering if you have any products for prolactinoma
At this time we don't have any natural herbs or products for prolactinoma patients.
I would like to know if you have any natural products that
could help with increasing my dopamine levels as I have a prolactinoma and would
like to reduce the level of prolactin in my body. As a result of my prolactinoma
I suffer from mood changes , depression, low libido, and a lot of pigmentation
on my face, are there herbs that could help with the pigmentation? I have been
taking chaste berry for some years, with minimal improvement. I am very much
against the medications that the endocrinoligists suggested, I tried them and I
kept vomiting and had bad headaches, and do not want to take these drugs for the
rest of my life.
You can review this page on dopamine, but I am not aware of any supplements or herbs that treat this condition.
Is l-dopa effective for lowering prolactin levels? Do you have any recommendations for folks with elevated levels? I currently take B6 (P5P) and zinc. I have idiopathic hyperprolactinemia; there is no tumor present on pituitary MRI so docs don't know why prolactin is elevated.
I am wondering if you know information associated with
prolactinoma patients taking aphanizomenon flos-aquuae and it being a success?
This is outside my range of knowledge.
