Is Melatonin Safe For Ckd

Don't Miss

Are There Any People Who Should Avoid Taking Melatonin

Melatonin may not be as safe as you think

Theres limited research into the safety of using melatonin supplements during pregnancy. Also, while melatonin is a normal component of breast milk, theres little research into the effects of taking melatonin supplements while breastfeeding.

Because of this, its best to avoid taking melatonin if youre:

  • pregnant

Its a good idea to schedule an appointment with your doctor or healthcare provider if you notice that you:

  • frequently have trouble falling asleep or staying asleep at night
  • often feel drowsy or tired during the day
  • have trouble performing your daily activities

Your doctor will work with you to discuss your sleep routine and lifestyle habits. They may also ask you to keep a sleep diary to track the amount of sleep youre getting over a period of time.

Its also possible that your doctor will perform a physical exam and order blood tests. These can help them rule out a medical condition that may be causing your sleep issues.

Is Quercetin Something You Should Take For Kidney Disease


  • Quercetin, a natural compound, has shown to have some benefits for kidney disease.
  • In recent years there have been multiple studies published on the benefits of quercetin for chronic kidney disease and people on dialysis.
  • Quercetin has anti-inflammatory and anti-oxidant benefits for the kidneys. It has also shown to improve symptoms of people on dialysis.

Quercetin is an antioxidant derived from food sources. Which is a flavonoid which is water soluble plant substance. Its found in some fruits and vegetables. But how does it measure up as a natural treatment for kidney disease?

Quercetin has many health benefits that many people arent aware of. Keep reading this article to discover more about quercetin, what foods its found in, uses and benefits.

In order to maintain good kidney health it is very important to use antioxidants since they fight free radicals in the body which can cause kidney disease. Antioxidants also form a type of shield and at the same time fixing damaged molecules.

Foods to try which contain Quercetin are red onions, garlic, organic apples, plums, red grapes and citrus fruits. Also dark cherries, blueberries, blackberries and bilberries, as well as capers and olive oil.

There are also herbs like parsley, sage, elder flower, ginkgo biloba and St. Johns Wort which contain quercetin.

It has also been found that quercetin can help with allergies as it works as an antihistamine.

Evaluation Of Sleeping Pill Exposure

Those who were not exposed to sleeping pills for > 3 years prior to the study period were included as nonusers of sleeping pills. Regular sleeping pill use was defined as constant sleeping pill use for > 90 days after the index date. Sleeping pill use periods with intervals between successive prescriptions exceeding 90 days were abandoned. To judge the association between sleeping pill exposure and further risk of ESRDd, we analyzed the incidence of ESRDd after CKD in those using sleeping pills compared with those not using sleeping pills.

Areyou At Risk For Kidney Disease

Most people with kidneydisease dont have any symptoms until theyre very sick. So unless your doctorhas tested your kidney function, you cant be sure that you dont have kidneyproblems.

A few simple tests will tellyour doctor how well your kidneys are working. He or she will:

  • Check your blood pressure.
  • Take a blood sample and test the levels of blood urea nitrogen and creatinine, which are indicators of how well your kidneys are cleaning your blood.
  • Take a urine sample to check for blood, infection or protein in your urine.

Even slightly higher thannormal blood pressure or cholesterol increases your risk for kidney disease,stresses Dr. Heyka. So keep your blood pressure, cholesterol and weight incheck, as well as your blood sugar if you have diabetes. And, as always, makesure you tell your doctor about every vitamin, herbal remedy and nutritionalsupplement you take.

Gaurav Nigam,1 Macario Camacho,2 Edward T Chang,2 Muhammad Riaz3 1Division of Sleep Medicine, Clay County Hospital, Flora, IL, 2Division of Otolaryngology, Sleep Surgery and Sleep Medicine, Tripler Army Medical Center, Honolulu, HI, 3Division of Sleep Medicine, Astria Health Center, Grandview, WA, USA Abstract: Kidney disorders have been associated with a variety of sleep-related disorders. 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.

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.

Use Of Herbal Supplements In Chronic Kidney Disease

  • Very few herbs have been studied in CKD patients. What may be safe for healthy persons may not be safe for someone with CKD, and in fact, could be dangerous. Therefore, you need to be very cautious about your use of these products.
  • The government does not regulate herbal supplements, so the exact content of these products is unknown.
  • Without regulation, there are no requirements for testing, so the purity, safety and effectiveness of the products are unknown.
  • Herbal preparations are subject to contamination .
  • Products may contain minerals harmful to CKD patients, for example: potassium.

First, we observed that administration of adenine or melatonin did not induce death. The body weights were lower in the CKD and CKD + M groups than the C group in both sexes . In males, adenine administration caused a higher kidney weight and higher kidney weight-to-BW ratio in the CKD group vs. the C group, which was attenuated by melatonin therapy in males but not in females. At nine weeks of age, the systolic BP and mean arterial pressure were increased in the CKD group in males. Female rats receiving adenine also developed an increase in BP not only in SBP and MAP, but diastolic BP as well, while the elevation of SBP in adenine-treated rats of both sexes was prevented by melatonin therapy. Additionally, illustrates that adenine administration caused higher creatinine levels in the CKD groups of both sexes, which was partially prevented by melatonin therapy in males but not in females.

The Role Of Melatonin In Kidney Health

Emily Cahill

The latest science is telling us that melatonins therapeutic reach may extend way beyond sleep and its almost getting easier to ask: what chronic diseases doesnt melatonin play a role in? Recent years have seen a flurry of studies showing the protective and therapeutic benefits of melatonin against the most significant chronic diseases of our time- heart disease, cancer, dementia, diabetes and yes kidney disease.

For this reason, I thought Id highlight some of the lesser known benefits of melatonin in todays article and how they relate to kidney disease.

So lets get into it.

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.

What To Know About Dietary Supplements And Safety

Melatonin 10 mg

The FDA classifies melatonin as a dietary supplement, meaning that its regulated less strictly than a regular drug. For dietary supplements, label claims and product safety dont have to meet FDA approval before theyre marketed.

A 2017 study of 31 different melatonin supplements found that the actual melatonin content of 71 percent of the products didnt match the claim on the label. Additionally, 26 percent of products contained serotonin, which can be potentially harmful even in small doses.

When shopping for melatonin supplements, look for products that are USP verified. United States Pharmacopeia is an independent organization that works to ensure proper quality and dosing of dietary supplements.

If you experience side effects from melatonin, stop taking it and speak with your doctor. They may recommend using a lower dose or trying out an alternative medication or sleep aid.

Background: Sleeping disorder has been associated with chronic kidney disease however, the correlation between sleeping pills use and CKD has not been investigated in-depth yet. This study elucidated the potential association of sleeping pill use with the risk of CKD and CKD progression to end-stage renal disease requiring dialysis.

Sleeping pill use was related to an increased risk of CKD and ESRD. Further studies are necessary to corroborate these findings.

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.

Can Diabetics Take Melatonin

Diabetics who experience sleeping problems might want to try melatonin, a common supplement that is thought to help regulate sleeping patterns. But diabetics must monitor the supplements they take to ensure they dont interfere with any other medications theyre taking. Another concern is whether a supplement, such as melatonin, affects blood sugar levels, which are prone to fluctuate rapidly in diabetics. Check with your doctor before taking any supplements.

If you are experiencing serious medical symptoms, seek emergency treatment immediately.

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 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.

Health Benefits Of Melatonin

Heres a closer look at the use of melatonin in alternative medicine and the possible health benefits:

1) Jet Lag

Travel across time zones disrupts the circadian rhythm. Preliminary evidence suggests that melatonin supplements can reduce certain jet-lag symptoms, particularly in people traveling eastward and/or crossing five or more time zones. Melatonin may improve alertness during the day, movement coordination, and to a lesser extent, daytime tiredness.

The best results seem to occur when melatonin supplements are started on the day of travel and taken at the desired bedtime at the destination. It is usually taken for several days.

2) Insomnia

Melatonin appears to lessen the time it takes to fall asleep, but only by about 12 minutes . A number of studies suggest that the optimal time to take melatonin supplements is between half an hour and two hours prior to the desired bedtime. There is some evidence that suggests that melatonin may be more helpful for older adults, possibly because they may have less melatonin in their bodies. Most studies have been small and short in duration, so further research is needed.

3) Shift Work

Although night shift work disrupts the circadian rhythm, there is little evidence supporting the notion that melatonin can adjust the sleep schedule in people who work at night and sleep during the day. It doesn’t appear to improve sleep after shift work or improve alertness during shift work.

4) Sleeping Problems Associated With Blindness
