Things That Reduce Melatonin Synthesis
The production of melatonin varies from person to person and is affected by other factors such as age , disrupted light/dark cycles, night work and being overweight. Studies have also shown that the production of melatonin is impaired in people with CKD.
Low levels of melatonin make it harder to fall asleep. In fact, the use of screen devices around bedtime is significantly associated with insomnia, poor sleep quality and daytime fatigue because it reduces the amount of melatonin we produce. The obvious effect of making less melatonin is trouble sleeping but Im going to show you that the consequences are far more wide reaching.
Is It Safe To Take More Than One Dose During The Night
You may be wondering what happens if you take a dose of melatonin and find that you still cant fall asleep. Can you take another dose?
While taking an additional dose is unlikely to cause harm, it may increase your risk for experiencing unwanted side effects.
If you find that melatonin isnt helping you fall asleep, stop using it. Your doctor may be able to suggest different medications or strategies to help you fall asleep.
There are some important things to know about melatonin, its interactions with other substances, and when its best to avoid it. Lets take a closer look.
Sleep Issues And Chronic Kidney Disease
People with chronic kidney disease often have trouble falling asleep and staying asleep. Your physical and mental health can contribute to your sleep problems. These are some common causes for disrupted sleep patterns in kidney disease patients.
Restless leg syndrome
Restless leg syndrome often occurs when the legs are at rest, such as when a person is sitting or lying in bed. The sensation varies from patient to patient. It can be irritating, itchy or painful. Some patients find that moving their legs makes the uncomfortable sensations lessen or go away entirely.
Doctors have determined that iron deficiency, caffeine, alcohol, tobacco, diabetes and certain medications can contribute to RLS.
Sleep apnea
Sleep apnea causes your breathing to be interrupted or stopped for more than 10 seconds while youre in a deep sleep. These non-breathing intervals are called apneas. Patients with sleep apnea often snore heavily. The snores continue until breathing is interrupted or stops, which signals an apnea. The person will then snort or gasp to take in air and the snoring continues until the next apnea.
A doctor can determine if you have sleep apnea by conducting a physical exam and a sleep study.

Is Melatonin Safe To Take Every Night
Americans arent sleeping well. Roughly 80% of U.S. adults say they struggle to fall asleep at least one night a week, according to a recent Consumer Reports survey. And research has found that sleep problems are also on the rise among adolescents.
While the causes of Americas sleep woes are up for debate, theres little disagreement about Americas favorite remedy: Melatonin, the countrys most-used sleep aid.
Melatonin Use Linked To Lower Risk For Vancomycin
Melatonin, a commonly used sleep aid, may significantly reduce the risk for acute kidney injury in patients treated with vancomycin, according to a new observational study published in Antimicrobial Agents and Chemotherapy.
In a retrospective cohort study at a large community medical center, researchers examined 303 hospitalized adult patients treated with vancomycin from January 2016 to September 2020. After controlling for potential confounders, melatonin use was significantly associated with 63% decreased odds of AKI.
The cohort consisted of 101 patients treated with melatonin as part of ordinary care and 202 control patients. The melatonin and control groups had a mean age of 60.9 and 64.4 years, respectively. The primary endpoint was development of AKI, defined as an absolute increase in serum creatinine of 0.3 mg/dL or higher or a 50% or greater increase in serum creatinine level. Both groups had similar characteristics, but the treatment group had a significantly higher incidence of bacteremia/sepsis .
We also suspect that melatonin alleviates mitochondrial stress. There are data that suggest damaged mitochondrial function in early AKI. Perhaps melatonin functions to alleviate oxidative stress and restore mitochondrial balance, Dr Brunetti said.
On univariate analysis, concomitant use of piperacillin-tazobactam and loop diuretics was significantly associated with 3.9-fold and 3.4-fold increased odds of AKI, respectively.

Assessment Of The Risk Of Bias
The methodological quality was assessed by using the CAMARADES 10-item checklist: peer-reviewed journal temperature control animals were randomly allocated blind established model blinded outcome assessment anesthetics used without marked intrinsic neuroprotective properties animal model calculation of sample size statement of compliance with animal welfare regulations possible conflicts of interest .
Two reviewers assessed the risk of bias. Bias was marked as high or low risk, as well as unclear indicated that the risk of bias was unclear. The symbol + was used to marked low risk, and it was also recorded as the point of quality score. Agreement over the quality assessment was determined using the Kw. The Kw value > 0.75 was accepted. Disagreements were resolved through discussion with the third reviewers .
Is It Safe For Kids
Melatonin is the second most used natural product for children.
Studies show that it can also help children with autism spectrum disorder , who tend to have lower levels of melatonin, and children with ADHD, who tend to have trouble falling asleep and staying asleep.
One recent study of 125 children and teens with ASD found that those who took larger doses â from 2 milligrams to 5 milligrams â of prolonged-release melatonin for 13 weeks were sleeping about an hour longer per night, with fewer sleep disturbances, by the end of the study.
âItâs generally safe, itâs not habit forming, and people donât really develop a tolerance for it,â Canapari said. âIt is my first-path sleep medication for children who need it.â
But other researchers say theyâre concerned about its safety.
In 2015, researchers from Australia published a study pointing to research that linked melatonin use on rodents to changes in when they start puberty. The report also notes that in the early 1990s, scientists were looking into high doses of melatonin as possible human birth control because of the way it could affect the reproductive system.
âConsidering the small advances melatonin provides to the timing of sleep, and considering what we know about how melatonin works in the body, it is not worth the risk to child and adolescent safety,â warned lead author David Kennaway, head of the Circadian Physiology Laboratory at the University of Adelaideâs Robinson Research Institute.

Renal Histology And Immunohistology
As expected, the remnant kidneys in the untreated rats showed significant glomerulosclerosis and tubulointerstitial damage. Melatonin administration significantly reduced the severity of glomerulosclerosis and tubulointerstitial damage. As shown in , glomerulosclerosis and the extension of tubular injury were reduced by approximately one-half in the melatonin-treated group.
Fig. 7.Light microscopic histology findings in the sham , Nx , and Nx + MEL are shown in top as the glomerulosclerosis index and extent of tubulointerstitial damage. Data are means ± SE. Bottom: contrasting appearance of a renal section of a rat in the Nx group and a rat in the Nx + MEL group .
The number of p65 NF-B-positive cells was increased in the untreated rats with renal ablation and was reduced significantly by administration of melatonin. The latter finding points to a inhibitory effect of melatonin on activation of this proinflammatory transcription factor . Lymphocyte and macrophage infiltration in tubulointerstitial areas was increased correspondingly in the untreated Nx rats and was decreased by 1.8-fold with melatonin treatment . Unlike the tubulointerstitial region, infiltration of lymphocytes and macrophages in the glomeruli was scarce .
Melatonin And Children With Adhd
As many as 70% of children with ADHD experience sleep problems. They frequently experience excessive daytime sleepiness caused by initial insomnia, or difficulty falling asleep at night.
Studies show that children with ADHD who take melatonin experience improved sleep. One study found a reduction in insomnia, leading to children falling asleep an average of 16 minutes earlier.

Therefore, researchers are placing greater emphasis on finding the role of chronic kidney disease in the development of obstructive sleep apnea and restless legs syndrome. Unfortunately, the presence of other sleep-related disorders with CKDs and non-CKDs has not been investigated with the same clinical rigor. Recent studies have revealed that myriad of sleep disorders are associated with CKDs. Furthermore, there are a few non-CKD-related disorders that are associated with sleep disorders. In this narrative review, we provide a balanced view of the spectrum of sleep disorders related to different types of renal disorders prominently including but not exclusively limited to CKD.

So What Does This Mean For Kidney Disease
Well, melatonin is protective to the kidneys for a number of reasons.
Probably the number one reason is due to its antioxidant and anti-inflammatory effects.
The kidneys are especially vulnerable to oxidative stress and damage from free radicals and prooxidants produced within the body which can lead to progressive kidney damage, so it makes sense then that boosting antioxidant levels within the body is one way to protect the kidneys.
In chronic injury , melatonin plays an important role by suppressing pro-inflammatory mediators and initiating a protective effect against inflammatory damage.
Melatonin also helps to lower the activity of the renin angiotensin system . Overactivity of the RAS increases blood pressure, causes sodium retention and contributes to inflammation and fibrosis . Reducing the activity of the RAS therefore lowers blood pressure, inflammation and reduces the development of fibrosis.
High blood pressure is the second leading cause of CKD and contributes to the progression of kidney disease so managing blood pressure will also have a protective effect on further damage to the kidneys. Vasodilation or relaxation of blood vessels also helps to prevent reduced blood and oxygen delivery to the kidneys which is another contributing factor to kidney damage.

Is A Melatonin Supplement Safer Than Other Sleeping Pills
For some people, melatonin can be just as effective at helping you fall asleep as prescription sleeping pills. But, you may wake feeling a little fresher. Prescription sleep aids can cause people to feel groggy and slow their reaction times the next day. Melatonin typically doesnt have this effect. Melatonin should not be combined with a prescription drug without first consulting the prescribing provider.
If your doctor has prescribed you a medication, its for a reason. Never stop a prescription without discussing it with your doctor first. The information in this article is not intended to replace your doctors advice.
Prescription sleeping pills can be addictive. Melatonin is showing the potential to help get patients off of long-term prescription sleeping pills and offers a safer alternative.
There is currently no evidence to suggest that you can develop a tolerance to melatonin.

How Does Melatonin Work
Natural melatonin is predominantly made in your pineal gland, which is located in your brain. Light exposure inhibits the production of melatonin, but darkness stimulates it.
Melatonin levels in your brain begin to increase at dusk as the sun goes down and darkness falls. They reach their peak levels in the middle of the night and start decreasing as dawn gets closer.
The action of melatonin inhibits signals in your brain that promote wakefulness. This helps encourage sleep by making you feel tired or drowsy as you get closer to bedtime.
Because of melatonins sleep-promoting effects, melatonin supplements are used to treat a variety of sleep problems. These can include:
Melatonin typically takes 1 to 2 hours to work, so its often taken up to 2 hours before bedtime.
If youre looking to try melatonin for the first time, it may be best to begin with a lower dose. Your doctor can help recommend a safe dose for you to start with.

Protective Effect Of Melatonin Related To Autophagy
Autophagy plays a cardinal contribution in renal I/R injury. Injurious autophagy may lead to the release of excessive ROS and pro apoptotic factors, which ultimately cause cell death . Yang et al. suggested that a major pathway for melatonin-induced autophagy in I/R injury involves activating the TLR4-MyD88 signaling pathway . Mitogen-activated protein kinases pathways is actived by the MyD88 pathway . Mammalian target of rapamycin complex 1 , a convergence point for many upstream pathways, including MAPKs, regulates autophagy. Yang et al. revealed that melatonin-induced autophagy among renal I/R mice was dependent on downregulation of mTORC1 by its upstream activator, the TLR4/MyD88 .
Otherwise, it is known that phosphatidylinositol-3-kinase /AKT/mTOR pathway perform a core effect to regulate cell survival, as well as cell growth, and proliferation . Another important finding of Chang YC was that PI3K/AKT/mTORC1 signaling pathway was significantly upregulated in the I/R kidney, while melatonin can significantly inhibit this signal pathway . It was claimed that the activation of PI3K/AKT/mTOR signaling under the I/R condition is the internal response of tissue or organs to I/R , and melatonin could reverse this situation .
Kidney Impairment Can Be Costly
Although renal impairment is often reversible if the offending drug is discontinued, the condition can be costly and may require multiple interventions, including hospitalization, Dr. Naughton explained. To help you avoid getting to that point, we learned about medications that commonly cause kidney damage from Rebekah Krupski, PharmD, RPh, pharmacy resident at the Cleveland Clinic and clinical instructor of pharmacy practice at Northeast Ohio Medical University.

Combining Melatonin With Vancomycin Reduces Kidney Failure
A study by researchers at the Rutgers Ernest Mario School of Pharmacy finds that melatonin significantly reduces kidney failure in people being treated with the antibiotic vancomycin.
The study, in the journal Antimicrobial Agents and Chemotherapy, examined 303 hospital patients being treated with vancomycin and found that 101 who also received melatonin had a 63 percent decrease in acute kidney injury.
Globally, antibiotic use is one of the leading causes of drug-induced kidney failure, with more than 13.3 million cases reported each year.
Kidney failure is also associated with an increased risk of death in hospitalized patients. Almost 25 percent of these patients die in hospitals when toxins build up as they also receive antibiotic treatments for various infections.
Weve known from previous studies the ability of vancomycin to induce kidney injury through oxidative stress and mitochondrial damage, and we also knew how melatonin could restore renal mitochondrial function, so making these findings in this small group of patients was promising and could lead to bigger therapeutic breakthroughs, said the studys lead author, Luigi Brunetti, an associate professor at the Rutgers Ernest Mario School of Pharmacy.
The study was the first to examine such human data, and researchers plan further clinical studies on a larger and broader population.
We hope our findings pave the way for larger group studies as acute kidney injury affects millions of people, Brunetti said.
What Medications And Substances Does Melatonin Interact With
Melatonin may interact with several different types of medications, including:
- Blood-thinning medications. Taking melatonin with blood-thinning medication may increase your risk for bleeding.
- Epilepsy medications . Melatonin may make these medications less effective.
- Immunosuppressants. Melatonin can potentially interfere with immunosuppressive drugs.
- Diabetes medications. Melatonin use can affect blood sugar levels.
- Blood pressure medications. Blood pressure may get worse when melatonin is taken with these medications.
- Contraceptive drugs.Birth control pills may increase the risk of side effects from melatonin.
Because melatonin supplements can make you tired and drowsy, avoid mixing them with:
- other sleep aids
