What is CircadiYin?

CircadiYin is a diet pill sold exclusively online through The supplement is designed as an all-natural supplement for supporting deep sleep, circadian rhythm, and metabolism.

Sleep is a crucial part of weight loss. If you don’t get enough sleep, then you’ll struggle to lose weight. Sleep is linked to metabolism, and a slow metabolism makes it hard to lose weight.

According to the official website, CircadiYin is an effortless, simple, and effective way to support deep sleep and weight loss:

“The science shows that when our circadian rhythm is disrupted, losing weight is considerably more difficult…So it makes sense to restore circadian rhythm first.”

Your circadian rhythm controls your natural sleep/wake cycles. When you disrupt your circadian rhythm, it makes it more difficult to fall asleep and wake up at a normal time.

Shift work, caffeine, drugs, illness, late night screen use, and ordinary lifestyle habits can all disrupt circadian rhythm, making it difficult to lose weight. CircadiYin claims to optimize your circadian rhythm and make it easier than ever to lose weight.

CircadiYin is exclusively available online through, where it’s priced at around $69 per bottle.

How Does CircadiYin Work?

CircadiYin is a weight loss supplement that claims to have helped over 100,000 people reclaim control of their bodies and their lives.

Other weight loss supplements fill your body with stimulants, vitamins, minerals, herbal extracts, and other weight loss compounds. CircadiYin, however, works in a different way: the supplement optimizes your sleep cycles, making it easier to naturally lose weight.

Your body has a natural sleep/wake cycle known as your circadian rhythm. Your circadian rhythm tells you when to wake up and fall asleep.

Our natural circadian rhythm corresponds to the earth’s day and night cycles. We naturally feel more awake in the mornings when the sun rises in the air. Then, as night falls, your circadian rhythm tells your body to produce melatonin, helping you fall asleep as it gets dark.

Modern lifestyles, however, can disrupt your circadian rhythm. Using a screen late at night, for example, can trick your body into thinking it’s day. If you’ve ever struggled to fall asleep after using your phone or computer late at night, then your screen time may have disrupted your circadian rhythm.

CircadiYin aims to help. CircadiYin aims to restore your circadian rhythm, making it easier to manage your sleep and wake cycles. That means you can fall asleep more easily, stay asleep for longer, and optimize your metabolism overnight.

How Sleep Affects Weight Loss

If you aren’t getting enough sleep, then you may struggle to lose weight – even if you’re carefully dieting and exercising.

Studies show there’s a connection between sleep quality and weight loss. If you aren’t getting adequate sleep, then your body may enter survival mode, making it more difficult to burn fat. You could be following a diet and exercise routine yet not losing weight because of poor sleep habits linked to your circadian rhythm.

In this 2011 study, for example, researchers found that sleep loss can modify energy intake and expenditure. Researchers analyzed the sleep habits of participants who were trying to lose weight. Researchers conclude that insufficient sleep quality undermined dietary efforts to lose weight. In a randomized setting, researchers found that people following similar diet and exercise programs were less likely to lose weight when they had a poor sleep schedule.

Similarly, this 2012 study found that adequate sleep could improve the treatment of obesity. While many weight loss specialists focused on dieting and exercising as primary ways to lose weight, researchers should also focus on sleep quality and sleep schedule maintenance. Researchers specifically found that people who slept 8.5 hours a night had twice as much energy expenditure as those who slept 5.5 hours per night.

Sleep problems could also disrupt your eating habits. It’s no secret that people who tend to stay up late eat more calories than those who go to bed early. You’re also more likely to eat unhealthy foods when staying up late at night: few people crave a salad at 11:30pm. All of those late night snacks could compromise your weight loss goals.

We know that eating and sleep are connected. But how does CircadiYin claim to help? What does CircadiYin do? Let’s take a closer look at what CircadiYin does to your body.

What Does CircadiYin Do?

CircadiYin uses natural ingredients to restore your body’s natural circadian rhythm.

Instead of flooding your body with stimulants or herbal extracts to help you lose weight, CircadiYin gives your body the ingredients you need to support a healthy sleep, allowing your body to lose weight naturally.

Some diet pills work by suppressing appetite, accelerating fat burning, or even making you sweat. CircadiYin works differently. By equipping your body with the tools needed for weight loss, CircadiYin can make it easier than ever to lose weight.

Like other sleep aid supplements, CircadiYin contains a significant dose of melatonin. There’s 10mg of melatonin in each two capsule serving of CircadiYin. Many people take melatonin nightly to help fall asleep. Studies show that a 2.5mg to 10mg dose of melatonin could kickstart your body’s natural sleep cycles and restore your circadian rhythm. Although 10mg may not seem like a large dose, the 10mg dose of melatonin in CircadiYin should be noticeable and could help you enjoy a deeper, more restful sleep.

CircadiYin also contains other popular sleep supplement ingredients like L-tryptophan, chamomile, lemon balm extract, and passion flower extract. These herbal extracts and amino acids have been used for centuries to support healthy sleep. Today, studies have reinforced the effects of these ingredients, showing they could help you fall asleep and stay asleep for a full night’s worth of rest.

CircadiYin Ingredients

CircadiYin consists of a bundle of vitamins, minerals, herbs, and plant extracts. Some of these ingredients have been used for centuries to optimize sleep.

Some of the most popular and proven ingredients in CircadiYin include:

Melatonin: Each serving of CircadiYin contains 10mg of melatonin. Although it’s not the largest ingredient in CircadiYin by weight, it may be the most noticeable ingredient. A 10mg dose of melatonin is considered strong, and many people will feel noticeably sleepy after taking this dose. By taking two capsules of CircadiYin at night when ready to fall asleep, you could optimize your circadian rhythm.

L-Tryptophan: L-tryptophan is the ingredient in turkey meat that makes us feel sleepy after Thanksgiving dinner. Today, many sleep supplements contain L-tryptophan for its ability to make us feel sleepy. CircadiYin contains a significant dose of L-tryptophan for that reason. It’s the first listed ingredient in the CircadiYin proprietary formula, suggesting there’s more L-tryptophan than any other ingredient in CircadiYin.

Goji Berry: Although not typically found in sleep aid supplements, goji berry is rich with antioxidants like vitamin C that have been linked to weight loss in multiple studies. Many people eat goji berry daily for that reason. Antioxidants neutralize free radicals throughout your body, supporting inflammation. Inflammation could make it harder to lose weight.

Chamomile: Chamomile and chamomile tea have been used for centuries for weight loss. Studies show that chamomile interacts with your brain chemicals to encourage feelings of relaxation, making it easier to fall asleep and stay asleep.

Ashwagandha: Prized as an adaptogen and used for centuries in Ayurvedic medicine, ashwagandha has surged in popularity in recent years. Many people take ashwagandha on its own daily for its ability to balance stress within the body. In CircadiYin, ashwagandha could help your body manage physical and mental stress more easily.

Other Ingredients: Other active ingredients in CircadiYin include lemon balm extract, L-taurine, hops, and St. John’s wort, among others. Many of these ingredients can be found in countless other sleep aids on the market. By supporting a healthy sleep, the ingredients in CircadiYin could make it easier to optimize metabolism and lose weight, among other active effects.

Scientific Evidence for CircadiYin

CircadiYin has not completed any clinical trials to verify it works as advertised, but this is normal for natural dietary supplements. However, all of the ingredients in CircadiYin have completed clinical trials. Many of the ingredients in CircadiYin have been connected to sleep and weight loss.

Melatonin is a proven way to support a healthy sleep. Although melatonin doesn’t work for everyone, studies show it can help many people restore a natural sleep schedule – especially when dealing with sleeplessness, shift work, late night screen usage, and other things that disrupt sleep. Most sleep supplements contain a 2.5mg to 10mg dose of melatonin, with CircadiYin containing the upper level of that range.

Lemon balm extract has anti-stress effects, according to multiple studies, which is why it has been traditionally used in sleep aids and relaxation supplements. In this review study published in Nutrients in 2018, researchers found that lemon balm extract has anti-stress effects that target mood and cognition. Although it works differently in everyone, lemon balm extract has chemicals that bind to receptors in the brain, supporting stress relief and making it easier to fall asleep.

L-tryptophan is one of the largest ingredients in CircadiYin. Multiple studies show that L-tryptophan impacts sleep and relaxation by influencing serotonin. Your body may need L-tryptophan to create serotonin, making tryptophan crucial for mood, relaxation, cognition, and sleep.

It’s also no secret that sleep is connected to weight loss. Studies show that a lack of sleep raises appetite, for example, making it more likely you’ll overeat throughout the day. Getting an adequate amount of sleep can also boost metabolism. Metabolism is the number of calories your body burns when at rest. Because of these mechanisms, sleep has a close connection to weight loss – which is why CircadiYin is marketed as both a sleep aid and weight loss aid.

Overall, CircadiYin contains a bundle of vitamins, minerals, nutrients, herbal extracts, plant compounds, and more linked to weight loss and sleep.
