What is Melatonin?
Melatonin is a hormone in your body that plays a role in sleep. The production and release of melatonin in the brain is connected to time of day, increasing when it's dark and decreasing when it's light. Melatonin production declines with age. Melatonin is also available as a supplement, typically as an oral tablet or capsule. Most melatonin supplements are made in a lab. People commonly use melatonin for sleep disorders, such as insomnia and jet lag.
Benefits of Melatonin
Keeping your GI tract healthy
A large amount of the body's melatonin is produced in the gut (though it doesn't travel to the rest of the body). There's a very high concentration of melatonin in the gut. Because of this, researchers believe it plays a role in supporting digestive health.
Melatonin may have a variety of effects on digestion. The research on melatonin has been on people with irritable bowel syndrome (IBS). This is a gastrointestinal disorder that causes abdominal pain and changes in your stool.
Helping acid reflux
The melatonin may help people with gastroesophageal reflux disease (GERD). More research is needed, though, before it can be recommended as part of reflux treatment. This is a common medication used to treat GERD. About 87% of the participants had less heartburn. That's better than the control group, who only took a PPI and saw a 58% drop in heartburn.
Melatonin eliminated upper abdominal pain in just over half of people with indigestion after 12 weeks.
Reducing heart risks
If you're taking melatonin, you may get some heart benefits as well. A handful of small studies have found some encouraging effects. This is a group of conditions that raises the risk of cardiovascular disease and diabetes. In the study, those who took a daily 5 mg dose of melatonin for 2 months had the following results:
Lower blood pressure;
Lower levels of the "bad" cholesterol, low-density lipoprotein (LDL);
Increased antioxidant activity, which protects cells from damage.
Helping migraines and headache
Melatonin may help make certain types of headaches less intense, particularly migraines. Melatonin may help with cluster headaches as well.
Pain relief
Melatonin may have some pain-relieving effects at higher doses. For instance, people with fibromyalgia — a chronic condition that causes pain all over the body — have had less pain after they started taking melatonin. They had some pain relief when taking 3 mg or 6 mg doses at bedtime. But pain was much less with doses of 9 mg to 15 mg.
Ease anxiety before medical procedures
Can melatonin help you keep calm? Yes, at least in some situations.
Melatonin worked as well as benzodiazepines like alprazolam (Xanax) and diazepam (Valium).
Melatonin was less sedating than those drugs.
People seemed to tolerate melatonin better.
Benzodiazepines can also be addictive, whereas melatonin isn't.
Some dentists are using melatonin to help reduce anxiety before dental procedures.
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.
What Are Normal Melatonin Levels?
Pineal melatonin levels vary widely based on your age and sex.
Newborn babies don't produce their own melatonin. Before birth, they receive melatonin from the placenta, and after birth, they can receive it through breast milk. A melatonin cycle appears when they're 2 to 3 months old.
Melatonin levels then continue to increase as your child ages, reaching peak levels right before puberty. Once puberty hits, there's a steady decrease in melatonin levels until it evens out in the late teens. In all ages after puberty, melatonin levels are higher in women and people assigned female at birth (AFAB) than in men and people assigned male at birth (AMAB).
Melatonin levels are then stable until around age 40, followed by a decline as you continue to age. In people who are over 90 years old, melatonin levels are less than 20% of young adult levels.
Different factors cause the decline in age-related melatonin production, including calcification of your pineal gland, which is very common, and issues with light detection due to eye conditions, such as cataracts.
If you undergo a test that measures your melatonin levels, your healthcare provider will let you know if your levels are within normal ranges based on your age and sex.
Melatonin sleep aids are growing in popularity, with 3 million Americans using them in 2012, according to a nationwide survey from the Centers for Disease Control and Prevention. If you're among them or are considering melatonin for sleep, it's smart to understand exactly how melatonin works.
Your body produces melatonin naturally. It doesn't make you sleep, but as melatonin levels rise in the evening it puts you into a state of quiet wakefulness that helps promote sleep.
Most people's bodies produce enough melatonin for sleep on their own. However, there are steps you can take to make the most of your natural melatonin production, or you can try a supplement on a short-term basis if you're experiencing insomnia, want to overcome jet lag, or are a night owl who needs to get to bed earlier and wake up earlier, such as for work or school.
If you'd like to harness melatonin's sleep-inducing effects, Buenaver recommends taking these steps.
Because of the potential for side effects and interactions with medications, people should take dietary supplements only under the supervision of a knowledgeable health care provider.
Some people may have vivid dreams or nightmares when they take melatonin. Taking too much melatonin may disrupt circadian rhythms (your "body clock").
Melatonin can cause drowsiness if taken during the day. If you are drowsy the morning after taking melatonin, try taking a lower dose.
Additional side effects include stomach cramps, dizziness, headache, irritability, decreased libido, breast enlargement in men (called gynecomastia), and reduced sperm count.
Pregnant or nursing women should not take melatonin because it could interfere with their fertility, or their pregnancy.
Melatonin is a hormone so patients with a history of hormonal-related issues should only use melatonin under the supervision of their physicians.
Some studies show that melatonin supplements worsened symptoms of depression. For this reason, people with depression should consult their doctor before using melatonin supplements.
Although many researchers believe that melatonin levels go down with age, newer evidence has brought this theory into question. People older than 65 should ask their doctor before taking melatonin supplements, so blood levels of this hormone can be monitored.
Melatonin for Sleep Disorders
Melatonin supplements are likely to benefit people with sleep disorders that affect their circadian rhythms. Supplemental melatonin may also benefit people with other types of sleep disorders, though results tend to be more variable and less impactful and prescription medications may be necessary.
Non-24-hour sleep-wake rhythm disorder (N24SWD): People with N24SWD, most of whom are blind, have circadian rhythms that do not synchronize with the 24-hour cycle of day and night. Taking melatonin an hour before bedtime
Delayed sleep-wake phase disorder (DSWPD): People with DSWPD, which mainly affects adolescents and young adults, aren't able to fall asleep until long after conventional or desired bedtimes. While melatonin supplements aren't a first-line treatment for DSWPD, they may help people with the disorder fall asleep earlier.
Insomnia: Melatonin is not typically prescribed as the sole treatment for insomnia, but it may be used alongside other therapies to help reduce the amount of time it takes to fall asleep at bedtime.
Shift work disorder: Small doses of melatonin may help people who work rotating or night shifts fall asleep more easily during the day. However, some experts warn against taking melatonin for this purpose, as it can be difficult for shift workers to effectively time its administration or to predict its effects.
L-theanine powder is an amino acid found in tea leaves, particularly green tea and loose-leaf tea, that has several potential health benefits. While L-theanine isn't essential for our survival, its presence in plants and fungi has been studied for its possible impact on our brain function. L-theanine can be taken by drinking certain teas like green teas, white teas or matcha. It can also be taken as a tablet or pill form.
Benefits of L-Theanine Powder
1.Anxiety and stress relief
Sipping on a hot cup of tea can help you feel at ease, and research suggests that it not only relaxes the mind, but it also does so without causing drowsiness. L-theanine decreased anxiety and improved symptoms.
2.Increased focus
Paired with caffeine, L-theanine may help increase focus and attention.
L-theanine (97 milligrams, or mg) and caffeine (40 mg) helped a group of young adults focus better during demanding tasks. A typical cup of coffee contains 95 mg of caffeine.
3.Better immunity
L-theanine may improve the function of the body's immune system. L-theanine could help decrease upper respiratory tract infections. L-theanine could help improve inflammation in the intestinal tract. However, more research is needed to confirm and expand on these findings.
4.Tumor and cancer treatment
L-theanine has also been associated with amplifying the anti-tumor effects of certain chemotherapy drugs. Because of these promising findings, L-theanine could also help improve chemotherapy's ability to fight cancer.
Although there's no definitive evidence to show that tea prevents cancer, a number of studies suggest that people who regularly drink tea have lower rates of cancer.
5.Blood pressure management
L-theanine may be beneficial for those who experience increased blood pressure in stressful situations.
L-theanine may also help boys diagnosed with attention deficit hyperactivity disorder (ADHD) sleep better.
A double-blind study looked at the effects of L-theanine on 98 boys ages 8 to 12 years old. A randomized group was given two 100 mg chewable tablets of L-theanine twice daily. The other group received placebo pills.
After 6 weeks, the group taking L-theanine had longer, more restful sleep. While the results are promising, more research is needed before it can be proven safe and effective, especially for children.
L-theanine improved sleep quality for those diagnosed with schizophrenia.
L-theanine improves sleep quality via anxiolysis (reducing anxiety), not sedation.
Scientists believe these effects may be due to theanine's ability to benefit levels of the following:
· Glutamate
· GABA (gamma-aminobutyric acid)
· Serotonin
· Dopamine
· Alpha-wave brain activity
L-theanine also impacted levels of the following when used with antipsychotic medication:
· Dehydroepiandrosterone (DHEA)
· DHEA's sulfate (DHEAS)
· Cortisol
· Brain-derived neurotrophic factor (BDNF)
Serum levels of brain-derived neurotrophic factor and cortisol to sulfate of dehydroepiandrosterone molar ratio associated with clinical response to L-theanine as augmentation of antipsychotic therapy in schizophrenia and schizoaffective disorder patients.
How to Take L-Theanine Powder?
L-theanine is available in several forms, including pills, liquids, capsules, and powders. You can also get some L-theanine by drinking certain green or black teas.
L-theanine can be taken on its own or in combination with other calming substances. For example, L-theanine is commonly combined with magnesium, a mineral thought to help regulate stress.
L-theanine can be taken at any time of day, including in the morning to help support healthy stress response and at night before bed to promote restful sleep.
Does L-Theanine Powder Help with Weight Loss?
L-Theanine is an amino acid that occurs naturally in tea leaves. It is frequently combined with caffeine and sold as a dietary supplement that may assist in weight loss. The combination of L-Theanine and caffeine can boost energy expenditure and metabolism, resulting in weight loss. Moreover, L-Theanine can help alleviate stress and anxiety, which can help combat emotional overeating.
L-Carnitine is an amino acid that has a crucial role in fat metabolism. It works by transporting fatty acids from stored fat to cells, where they can be utilized as an energy source. Numerous studies have been conducted to examine the effects of L-Carnitine on weight loss. Taking L-Carnitine may increase fat oxidation, which in turn, can help reduce body fat. However, other studies have found that L-Carnitine has no significant impact on body weight or body fat. It is typically taken before exercising.
Green tea components in the recent years have witnessed a tremendous increase in interest among consumers due to their potential health benefits. The important bioactive constituent as a restorative is the amino acid l-theanine, which is also well known as a psycho-physiologically active agent. The relaxation effect of l-theanine is an interesting topic documented worldwide. Also, the anti-anxiety features of l-theanine are achieved through enhanced alpha electric band generation in occipital and parietal region of brain and increased synthesis of γ-aminobutyric acid (GABA). The supportive mechanism behind such activity revealed that enhanced GABA levels helps increase level of brain's dopamine and reduce serotonin levels that ultimately result in general feelings of calm and well being.
It is noteworthy to mention that unlike other conventional anti-anxiety treatments, l-theanine did not result in increased drowsiness, slowed reflexes, or impaired concentration. That ingestion of 200 mg of l-theanine changes the electrical activity in the brain by increasing alpha electric band measured by EEG. Earlier reports showed the dose dependent features of l-theanine on the brain activity can be prolonged and could typically last 8–10 h.
However, the original claims relating to the calming effect of l-theanine show it is usually noted within 40–60 min after l-theanine ingestion at a dose of 50–200 mg. Effective dose of 200 mg of l-theanine in the present study to induce relaxation is well consistent with the work. Thus, the data could be recorded during relaxing up to 60 min and time dependently monitored during the visual attentional and audio responds tasks.
