Melatonin is a hormone that your brain produces in response to darkness. It helps with the timing of your circadian rhythms (24-hour internal clock) and with sleep. Being exposed to light at night can block melatonin production.
Research suggests that melatonin plays other important roles in the body beyond sleep. However, these effects are not fully understood.
Melatonin dietary supplements can be made from animals or microorganisms, but most often they’re made synthetically. The information below is about melatonin dietary supplements.

Melatonin supplements may help with certain conditions, such as jet lag, delayed sleep-wake phase disorder, some sleep disorders in children, and anxiety before and after surgery.

Jet lag affects people when they travel by air across multiple time zones. With jet lag, you may not feel well overall and you may have disturbed sleep, daytime tiredness, impaired functioning, and digestive problems.
Research suggests that melatonin supplements may help with jet lag. This is based on medium-sized reviews from 2010 and 2014.
- Four studies that included a total of 142 travelers showed that melatonin may be better than a placebo (an inactive substance) in reducing overall symptoms of jet lag after eastward flights. Another study of 234 travelers on eastward flights looked at only sleep quality and found low-quality evidence that melatonin may be better than placebo for improving sleep quality.
- Two studies that included a total of 90 travelers showed that melatonin may be better than a placebo in reducing symptoms of jet lag after westward flights.

People with DSWPD have trouble falling asleep at the usual times and waking up in the morning. They typically have difficulty getting to sleep before 2 to 6 a.m. and would prefer to wake up between 10 a.m. and 1 p.m.
Melatonin supplements appear to help with sleep in people with DSWPD, but it’s uncertain whether the benefits outweigh the possible harms. This is based on a clinical practice guideline, a small review, and a more recent study.
- In 2015, the American Academy of Sleep Medicine recommended melatonin supplements given at specific times for DSWPD. The recommendation was a weak one, and it came with uncertainty about whether the benefits of melatonin outweigh its potential harms.
- A 2016 review that looked at a small number of people (52) from two studies showed that melatonin supplements reduced the time it took for people with DSWPD to fall asleep when compared to placebo. On average, it took about 22 minutes less for them to fall asleep.
- A 2018 randomized controlled trial that lasted 4 weeks and included 307 people with DSWPD found that taking melatonin 1 hour before the desired bedtime combined with going to bed at a set time led to several improvements. Those improvements included falling asleep an average of 34 minutes earlier, better sleep during the first third of the night, and better daytime functioning.

Sleep problems in children can have undesirable effects on their behavior, daytime functioning, and quality of life. Children with certain conditions, such as atopic dermatitis, asthma, attention-deficit hyperactivity disorder (ADHD), or autism spectrum disorder (ASD), are more prone to sleep problems than other children.
There are no overall guidelines on the best approach to improving sleep in children. However, guidelines for specific conditions recommend behavioral treatments, such as good bedtime habits and parent education, as an initial treatment that may be supplemented with medicines.
The list below shows the review’s results on melatonin’s short-term effects for children with specific conditions.
- Children with ASD fell asleep 37 minutes earlier and slept 48 minutes longer.
- Children with ADHD fell asleep 20 minutes earlier and slept 33 minutes longer.
- Children with atopic dermatitis fell asleep 6.8 minutes earlier and slept 35 minutes longer.
- Children with chronic sleep-onset insomnia fell asleep 24 minutes earlier and slept 25 minutes longer.
Because there aren’t many studies on children and melatonin supplements, there is a lot we don’t know about the use of melatonin in children. For example, there are uncertainties about what dose to use and when to give it, the effects of melatonin use over long periods of time, and whether melatonin’s benefits outweigh its possible risks. Because melatonin is a hormone, it’s possible that melatonin supplements could affect hormonal development, including puberty, menstrual cycles, and overproduction of the hormone prolactin, but we don’t know for sure.
Because of these uncertainties, it’s best to work with a health care provider if you’re considering giving a child melatonin for sleep problems.

Anxiety before and after surgery happens in up to 80 percent of patients.
Melatonin supplements appear to be helpful in reducing anxiety before surgery, but it’s unclear if it helps to lower anxiety after surgery. This is a based on a 2015 review.
- The 2015 review looked at 12 studies that involved 774 people and assessed melatonin supplements for treating anxiety before surgery, anxiety after surgery, or both. The review found strong evidence that melatonin is better than placebo at reducing anxiety before surgery. Melatonin supplements may be as effective as standard treatment (the antianxiety medicine midazolam). However, the results on melatonin’s benefits for reducing anxiety after surgery were mixed.

Current research looking at the effects of melatonin on COVID-19 is only in the early stages. There are a few randomized controlled trials (studies evaluating melatonin in people) in progress. At this point, it is too soon to reach conclusions on whether melatonin is helpful for COVID-19.
.header_greentext{color:green!important;font-size:24px!important;font-weight:500!important;}.header_bluetext{color:blue!important;font-size:18px!important;font-weight:500!important;}.header_redtext{color:red!important;font-size:28px!important;font-weight:500!important;}.header_darkred{color:#803d2f!important;font-size:28px!important;font-weight:500!important;}.header_purpletext{color:purple!important;font-size:31px!important;font-weight:500!important;}.header_yellowtext{color:yellow!important;font-size:20px!important;font-weight:500!important;}.header_blacktext{color:black!important;font-size:22px!important;font-weight:500!important;}.header_whitetext{color:white!important;font-size:22px!important;font-weight:500!important;}.header_darkred{color:#803d2f!important;}.Green_Header{color:green!important;font-size:24px!important;font-weight:500!important;}.Blue_Header{color:blue!important;font-size:18px!important;font-weight:500!important;}.Red_Header{color:red!important;font-size:28px!important;font-weight:500!important;}.Purple_Header{color:purple!important;font-size:31px!important;font-weight:500!important;}.Yellow_Header{color:yellow!important;font-size:20px!important;font-weight:500!important;}.Black_Header{color:black!important;font-size:22px!important;font-weight:500!important;}.White_Header{color:white!important;font-size:22px!important;font-weight:500!important;} Does melatonin help with cancer symptoms?
Studies of the effect of melatonin supplements on cancer symptoms or treatment-related side effects have been small and have had mixed results.
Keep in mind that unproven products should not be used to replace or delay conventional medical treatment for cancer. Also, some products can interfere with standard cancer treatments or have special risks for people who’ve been diagnosed with cancer. Before using any complementary health approach, including melatonin, people who’ve been diagnosed with cancer should talk with their health care providers to make sure that all aspects of their care work together.

People with insomnia have trouble falling asleep, staying asleep, or both. When symptoms last a month or longer, it’s called chronic insomnia.
According to practice guidelines from the American Academy of Sleep Medicine (2017) and the American College of Physicians (2016), there’s not enough strong evidence on the effectiveness or safety of melatonin supplementation for chronic insomnia to recommend its use. The American College of Physicians guidelines strongly recommend the use of cognitive behavioral therapy for insomnia (CBT-I) as an initial treatment for insomnia.

Shift work that involves night shifts may cause people to feel sleepy at work and make it difficult to sleep during the daytime after a shift ends.
According to two 2014 research reviews, studies on whether melatonin supplements help shift workers were generally small or inconclusive.
- The first review looked at 7 studies that included a total of 263 participants. The results suggested that (1) people taking melatonin may sleep about 24 minutes longer during the daytime, but (2) other aspects of sleep, such as time needed to fall asleep, may not change. The evidence, however, was considered to be of low quality.
- The other review looked at 8 studies (5 of which were also in the first review), with a total of 300 participants, to see whether melatonin helped promote sleep in shift workers. Six of the studies were high quality, and they had inconclusive results. The review did not make any recommendations for melatonin use in shift workers.

For melatonin supplements, particularly at doses higher than what the body normally produces, there’s not enough information yet about possible side effects to have a clear picture of overall safety. Short-term use of melatonin supplements appears to be safe for most people, but information on the long-term safety of supplementing with melatonin is lacking.
Also keep in mind:
Interactions with medicines
- As with all dietary supplements, people who are taking medicine should consult their health care providers before using melatonin. In particular, people with epilepsy and those taking blood thinner medications need to be under medical supervision when taking melatonin supplements.
Possible allergic reaction risk
- There may be a risk of allergic reactions to melatonin supplements.
Safety concerns for pregnant and breastfeeding women
- There’s been a lack of research on the safety of melatonin use in pregnant or breastfeeding women.
Safety concerns for older people
- The 2015 guidelines by the American Academy of Sleep Medicine recommend against melatonin use by people with dementia.
- Melatonin may stay active in older people longer than in younger people and cause daytime drowsiness.
Melatonin is regulated as a dietary supplement
- In the United States, melatonin is considered a dietary supplement. This means that it’s regulated less strictly by the Food and Drug Administration (FDA) than a prescription or over-the-counter drug would be. In several other countries, melatonin is available only with a prescription and is considered a drug.

- Some melatonin supplements may not contain what’s listed on the product label. A 2017 study tested 31 different melatonin supplements bought from grocery stores and pharmacies. For most of the supplements, the amount of melatonin in the product didn’t match what was listed on the product label. Also, 26 percent of the supplements contained serotonin, a hormone that can have harmful effects even at relatively low levels.

In addition to issues mentioned above, there are some things to consider regarding melatonin’s safety in children.
- Parents considering giving their children melatonin should first speak with a health care provider about melatonin use in children.
- A 2023 study found that 22 out of 25 over-the-counter melatonin gummy products were inaccurately labeled. One product did not contain detectable levels of melatonin. In the remaining products, the melatonin levels ranged from 74 to 347 percent of the labeled quantity (i.e., up to almost 3.5 times more melatonin than reported on the label). Most had more than the label said, with the majority containing between 1.2 to 1.7 times more melatonin than the amount listed.
- Parents need to ensure safe storage and appropriate use of melatonin supplements. Based on case surveillance data, a 2024 report by the U.S. Centers for Disease Control and Prevention (CDC) estimated that from 2019 to 2022, 11,000 emergency department visits were for unsupervised melatonin ingestion by children 5 years and younger. The report noted that many of the incidents involved ingestion of flavored products such as gummies and emphasized the importance of keeping medications and supplements out of children’s reach and sight.
- A 2022 study indicated that U.S. sales of melatonin—which is widely available in tablet, capsule, liquid, and gummy formulations—increased by about 150 percent between 2016 and 2020. The study authors said that the increase in sales, availability, and widespread use of melatonin in the United States has likely resulted in increased access to melatonin among children in the home.
- The 2022 study also showed that the number of reports to U.S. poison control centers about people 19 years and younger who took melatonin increased from 8,337 in 2012 to 52,563 in 2021. Over the 10-year period, the number of reports increased each year. Hospitalizations and serious outcomes from melatonin ingestion by people 19 years and younger also increased over the 10 years. Most hospitalizations involved teenagers who had intentionally taken melatonin overdoses, and the largest increase in hospitalizations occurred in children 5 years and younger.

- Most of the calls to poison control centers—94.3 percent—were for children 5 years and younger who accidentally consumed melatonin products in their homes.
- Data from the calls show that most of the people who had taken melatonin—82.8 percent—did not have any symptoms. Among those who did have symptoms, gastrointestinal, cardiovascular, or symptoms related to the central nervous system were the most common.
- Of the 4,097 people who were hospitalized over the 10-year period, 287 needed intensive care.
- Five individuals required mechanical ventilation, and two children younger than age 2 died, but the data from the poison control centers did not show whether the two deaths were caused by a melatonin overdose or another cause.
Melatonin supplements at normal doses appear to be safe for most children for short-term use, but there aren’t many studies on children and melatonin. Also, there’s little information on the long-term effects of melatonin use in children. Because melatonin is a hormone, it’s possible that melatonin supplements could affect hormonal development, including puberty, menstrual cycles, and overproduction of the hormone prolactin, but we don’t know for sure.
Possible melatonin supplement side effects reported in children have usually been mild and have included:
- Increased bedwetting or urination in the evening

A 2015 review on the safety of melatonin supplements indicated that only mild side effects were reported in various short-term studies that involved adults, surgical patients, and critically ill patients. Some of the mild side effects that were reported in the studies included:
The possible long-term side effects of melatonin use are unclear.

- Remember that even though the FDA regulates dietary supplements, such as melatonin, the regulations for dietary supplements are different and less strict than those for prescription or over-the-counter drugs.
- Some dietary supplements may interact with medicines or pose risks if you have medical problems or are going to have surgery.
- If you’re pregnant or nursing a child, it’s especially important to see your health care provider before taking any medicine or supplement, including melatonin.
- If you use dietary supplements, such as melatonin, read and follow label instructions. “Natural” doesn’t always mean “safe.” For more information, see Using Dietary Supplements Wisely .
- Take charge of your health—talk with your health care providers about any complementary health approaches you use. Together, you can make shared, well-informed decisions.

CARR publishes illustrative examples on determining fallback rates on floating rate notes that reference CDOR
CARR is publishing two presentations to clarify how CARR’s recommended fallback rate for floating rate notes that reference CDOR should be implemented for calculating the coupon and accrued interest post June 2024.
The first presentation from CMHC provides two illustrative examples on how to determine the appropriate fallback rate from the Bloomberg FBAK page for the calculation of the floating rate note coupon. Using Canada Mortgage Bonds examples, the presentation provides guidance on the necessary steps required to determine the fallback rate for all cash securities except NHA MBS. The presentation also includes details on the fallback rate calculation for NHA MBS.
The second presentation, from Bloomberg, demonstrates how the accrued interest is calculated for CORRA based floating rate notes, including for those notes that use CARR’s recommended fallback language.
Participants can refer to CARR’s recommended fallback language for all cash securities except NHA MBS, for further information on fallbacks rates and specific language. CARR’s recommended fallback for NHA MBS is available here . CMHC’s NHA MBS Advice No. 20 provides additional direction to issuers on the applicable fallback provisions for CDOR in the NHA MBS Program .
Canada established CARR, a working group sponsored by the Canadian Fixed-Income Forum , to coordinate Canadian interest rate benchmark reform. CARR’s mission is to ensure Canada’s interest rate benchmark regime is robust, resilient and effective in the years ahead. Over the coming transition period, CARR will support the transition from CDOR to CORRA as the key Canadian interest-rate benchmark.
Visit CARR’s webpage for up-to-date information on the transition, including all of CARR’s key documents, and to sign-up to receive email updates from CARR.

COVID-19: Who's at higher risk of serious symptoms?
Advanced age and some health conditions can raise the risk of serious COVID-19 (coronavirus disease 2019) illness.
Many people with COVID-19, also called coronavirus disease 2019, recover at home. But for some, COVID-19 can be a serious illness. Some people may need care in the hospital, treatment in the intensive care unit and the need for breathing help. In some people, severe COVID-19 illness can lead to death.
What raises the risk of severe or critical COVID-19 illness?
The risk for serious COVID-19 illness depends on your health status, age and activities. Your risk also depends on other factors. This includes where you live, work or learn, how easy it is for you to get medical care, and your economic stability.
If you have more than one risk factor, your risk goes up with each one.
Age raises the risk of serious COVID-19
People age 65 and older and babies younger than 6 months have a higher than average risk of serious COVID-19 illness. Those age groups have the highest risk of needing hospital care for COVID-19.
Babies younger than 6 months aren't eligible for the COVID-19 vaccine, which adds to their risk. For older people, the challenge is that the immune system is less able to clear out germs as people age. Also, as people age, medical conditions that raise the risk of severe COVID-19 are more likely. In the U.S. as of March 2024, about 76% of all deaths from COVID-19 have been among people age 65 and older.
Aging plus disease raises the risk of serious COVID-19
Severe COVID-19 disease is more likely for people who have other health issues.
Some common diseases linked to aging are:
- Heart disease. Examples are heart failure or coronary artery disease.
- Diabetes mellitus. The risk is higher for both type 1 and type 2.
- Chronic lung diseases. This includes airway disease and conditions that damage lung tissue.
- Obesity. The risk goes up as body mass index (BMI) increases, with the highest risk for a BMI of 40 or greater.
- Chronic kidney disease. Especially if you are on dialysis.
These diseases become more common as people age. But they can affect people of any age. The risk of serious COVID-19 illness is linked to having one or more underlying medical condition.
Asthma, COPD, other lung diseases raise risk of severe COVID-19
Your risk of having more severe COVID-19 illness is higher if you have lung disease. Having moderate to severe asthma raises some risks of serious COVID-19 illness. It raises the risk of needing care in the hospital, including intensive care, and needing mechanical help breathing.
The risk of serious COVID-19 illness also is higher for people who have conditions that damage lung tissue over time. Examples are tuberculosis, cystic fibrosis, interstitial lung disease, bronchiectasis or COPD, which stands for chronic obstructive pulmonary disease. These diseases raise the risk of needing care in the hospital for COVID-19. Depending on the condition, the risk of needing intensive care and the risk of death from COVID-19 also may go up.
Other lung conditions, such as a history of pulmonary hypertension or pulmonary embolism affect a person's risk of serious illness after COVID-19. The risk of death may be higher after these conditions.
Cancer raises the risk of severe COVID-19
In general, people with cancer have a greater risk of getting serious COVID-19. People who have or had blood cancer may have a higher risk of being sick for longer, or getting sicker, with COVID-19 than people with solid tumors.
Having cancer raises the risk of needing care in the hospital, intensive care and the use of breathing support. Having blood cancer and getting COVID-19 raises the risk of death from the illness.
Treatment for blood cancer may raise the risk of severe COVID-19 but the research is still unclear. Cancer treatment may also affect your COVID-19 vaccine. Talk to your healthcare professional about additional shots and getting vaccinated after treatments that affect some immune cells.
Other conditions that raise the risk of severe COVID-19
If an organ or body system is already weakened by disease, infection with the COVID-19 virus can cause further damage. In other cases, medicine for the original condition can lower the immune system's response to the virus that causes COVID-19.
Many different diseases can raise the risk of severe COVID-19 illness.
- Brain and nervous system diseases, such as strokes.
- Chronic liver disease, specifically cirrhosis, nonalcoholic fatty liver disease, alcoholic liver disease and autoimmune hepatitis.
- HIV not well managed with medicine.
- Heart disease, including congenital heart disease and cardiomyopathies.
- Mood disorders or schizophrenia.
- Having received an organ or stem cell transplant.
- Sickle cell anemia and thalassemia blood disorders.
Other risk factors for severe COVID-19 are:
- Not getting enough physical activity.
- Pregnancy or having recently given birth.
- Use of medicines that lower the immune system's ability to respond to germs.
Also, as a general group, disability is linked to an increased risk of severe COVID-19. The risks are different depending on the disability.
- Down syndrome is linked to a higher risk of needing care in the hospital. The risk of death from severe COVID-19 also is higher than typical for people with Down syndrome.
- Attention deficit/hyperactivity disorder is linked to an increased risk of needing care in the hospital from severe COVID-19.
- Cerebral palsy is linked to an increased risk of needing care in the hospital from severe COVID-19.
These are not the only conditions that increase the risk of severe COVID-19. Talk to your healthcare professional if you have questions about your health and risk for getting a serious COVID-19 illness.
A COVID-19 vaccine can lower your risk of serious illness
The COVID-19 vaccine can lower the risk of death or serious illness caused by COVID-19. Your healthcare team may suggest added doses of COVID-19 vaccine if you have a moderately or seriously weakened immune system.
How else can you lower the risk of severe COVID-19?
Everyone can lower the risk of serious COVID-19 illness by working to prevent infection with the virus that causes COVID-19.
- Avoid close contact with anyone who is sick or has symptoms, if possible.
- Use fans, open windows or doors, and use filters to move the air and keep any germs from lingering.
- Wash your hands well and often with soap and water for at least 20 seconds. Or use an alcohol-based hand sanitizer with at least 60% alcohol.
- Cough or sneeze into a tissue or your elbow. Then wash your hands.
- Clean and disinfect high-touch surfaces. For example, clean doorknobs, light switches, electronics and counters regularly.
- Spread out in crowded public areas, especially in places with poor airflow. This is important if you have a higher risk of serious illness.
- The U.S. Centers for Disease Control and Prevention recommends that people wear a mask in indoor public spaces if COVID-19 is spreading. This means if you're in an area with a high number of people with COVID-19 in the hospital. They suggest wearing the most protective mask possible that you'll wear regularly, that fits well and is comfortable.
These basic actions are even more important for people who have weakened immune systems, and their caregivers.
The FDA also has authorized the monoclonal antibody pemivibart (Pemgarda) to prevent COVID-19 in some people with weakened immune systems.
People can take other actions based on their risk factors.
- If you're at a higher risk of serious illness, talk to your healthcare professional about how best to protect yourself. Know what to do if you get sick so you can quickly start treatment.
- Lower your risk of COVID-19 complications by making sure that any health issues are well managed. This includes staying on track with managing medical conditions, going to all healthcare appointments and planning ahead to avoid running out of medicine. Keep taking medicines as suggested by your healthcare professional.
- Stay up to date on vaccines. This includes vaccines for flu, pneumonia and RSV. These vaccines won't prevent COVID-19. But becoming ill with a respiratory illness may worsen your outcome if you also catch COVID-19.
You may consider making a care plan. In the care plan, write your medical conditions, the medicine you take, and any special food or diet needs you have. The care plan also includes who you see for care and your emergency contacts.
