Envy Nutrition's Night Time Fat Burner: Full Review

Overall Envy Nutrition's Night Time Fat Burner Score: 2.2/5.0
Envy Nutrition's Night Time Fat Burner

Weight loss supplements that claim to work while you’re asleep have recently become very popular. Of course these types of supplements can’t do all the work on their own, they can be very effective, if you find the right one. Unfortunately, finding “the right one” can be hard.

We work hard to give you accurate information on everything that goes into weight loss supplements so you can figure out which one is right for you. Let’s take a look at Night Time Fat Burner so you can see what it can do for you and, more importantly, what it can’t.

What Is Night Time Fat Burner?

Official Product Name:

Night Time Fat Burner

What Is Night Time Fat Burner?

It is a night time diet pill and is made by the company Envy Nutrition. This supplement contains 8 ingredients and claims that they can boost your metabolism and suppress your appetite while you sleep. 

Is Night Time Fat Burner Recommended?

Night Time Fat Burner isn’t highly recommended. It contains conflicting ingredients that can have a negative impact on your sleep. Sleep is very important for weight loss. Having a “night time” formula that doesn’t fully support good sleep makes it hard to use. 

Where Can Night Time Fat Burner Be Purchased?

You can purchase Night Time Fat Burner from many different websites across the internet. You can also find it at the official Envy Nutrition website, Amazon, and Walmart. The price differs depending on where you buy it from, but it typically costs around $20-$30.

What Does It Mean To Get Better Weight Loss?

Trying to lose weight is a hard task, and many people across the globe struggle with doing so. Getting better weight loss is one of the best ways to reach your goals and stop worrying about what’s holding you back.

When thinking about what it means to get better weight loss, what it really comes down to is you. You have a chance to reach your goals, and we want to help you take it. Finding a way to achieve better weight loss can make a huge difference, even in your normal day to day life. Better weight loss can help you think, look, and feel better.

What Does It Mean To Get Better Sleep?

Nothing beats waking up refreshed and ready for the day. Getting better sleep is essential for a properly functioning body and can make every morning feel better. People also enjoy its ability to increase weight loss on its own. However, just “better” sleep isn’t always enough, you need to get good, high quality sleep. 

High quality sleep can give you so many different health benefits. Plus, poor sleep is linked to higher body weight. So why not kill two birds with one stone by getting better sleep?

Who Is Night Time Fat Burner For?

Night Time Fat Burner can be taken by almost anyone who is 18 years of older. But, that doesn’t mean it’s made for everyone. It should not be used by anyone who is pregnant or nursing. If you have a medical condition or are currently prescribed any medications, we strongly recommend consulting your doctor before taking.

What’s The Best Way To Use Night Time Fat Burner?

It is recommended to take one capsule, once a day, with 8 ounces of water. It should be taken about 20-30 minutes before a meal. When it comes to night time supplements, we typically recommend doing this as close to bedtime as possible. 

However, because this supplement contains an ingredient that has caffeine in it, this supplement could potentially have a negative effect on sleep if taken too close to bedtime. We recommend using caution with this product and testing out what time will work best for you, if you choose to purchase it. 

Envy Nutrition’s Night Time Fat Burner Ingredients

The ingredients in every weight loss formula are the most important part to investigate when evaluating supplements. The formula that makes up a diet pill gives you the most information about it. It can tell you side effects, benefits, and if it works for the supplement’s goal. 

This supplement includes 8 ingredients that are common in weight loss and sleeping supplements. Based on a surface glance, our biggest concern is that it is supposed to be a night time formula, but it contains green coffee bean extract which has caffeine in it. This could potentially have the opposite of a sleeping affect.

White Kidney Bean Extract Powder

Kidney beans are native to Central America and Mexico. People claim that it can be used to block carb absorption, burn fat, enhance athletic performance, and suppress appetite. This is an ingredient we like to see in weight loss supplements. But, when it comes to this ingredient, it is important for it to be included in the right mix. Although, some research has found that it can have a small effect on weight loss by itself. 

Some researchers wanted to investigate the effects of white kidney bean extract on weight loss. In order to research these effects, they reviewed multiple studies on this subject. In this investigation, they found that it has the potential to support weight loss and may be able to reduce the absorption rate of carbs. It is important to note that this study was sponsored by a company that sells white kidney bean extract power supplements. (7)

Green Coffee Bean Extract

Green coffee beans aren’t anything fancy. They are regular, raw, and unroasted coffee beans. People have recently found use for it as a weight loss ingredient and it has gained quite a bit of popularity in this category. Unfortunately this ingredient does contain caffeine which is known to negatively affect sleep if taken too close to bed (as this supplement recommends that you do). Some studies have found that it can have some effects on weight loss.

A systematic review was performed to find the effects that green coffee extract has on weight loss in humans. 3 studies met the needed criteria and were included in this review. These findings showed that green coffee extract was correlated with a significant decrease in body weight when compared to a placebo, but the magnitude of this change was only moderate. It is important to note that all studies were associated with a high risk of bias. (2)


This ingredient is an amino acid that promotes relaxation without creating drowsiness. It isn’t produced by the body or essential for humans, but it has become popular in supplements due to its suggested benefits. Outside of supplements it is most commonly found in tea leaves. In this formula, it is included for its ability to help improve sleep and reduce stress before bed.

In a randomized, placebo controlled, cross over, and double blind study, researchers tested the effects of L-theanine supplementation on stress. A total of 30 subjects participated in this experiment. Every day for 4 weeks, subjects were given either 200 mg of L-theanine or a placebo. Researchers found that when compared to the placebo, people who took L-theanine showed decreased stress related symptoms, increased sleep quality, and improved cognitive functions. (6)


L-tryptophan is also an amino acid, that is primarily used in the body to help promote better sleep quality, reduce anxiety, increase emotional well-being, and manage pain tolerance. It cannot be created by the body and is considered to be an essential amino acid. In this supplement its primary purpose is to help increase sleep quality.  

A study was done to investigate the effects of increased L-tryptophan on sleep and melatonin secretion. Thirty-three men participated in this 5 day and 4 night experiment. Participants were divided into 4 groups: tryptophan rich meal with low light exposure, poor tryptophan meal with low light exposure, tryptophan rich meal with high light exposure, and poor tryptophan meal with high light exposure. A higher increase of melatonin production at night was found in those eating a tryptophan rich meal with high light exposure during the day, when compared to the other 3 groups. (5)

Valerian Root Extract

The flowers of this plant were originally used to make perfumes before people discovered the benefits that the root holds. Nowadays the root is most commonly used to help promote relaxation and support better sleep. Scientists are still a little unsure about how exactly it works, but it is speculated that consumption of the root increases GABA (a sleeping and relaxing chemical made in the brain). 

In order to test the effects of valerian root supplementation on sleep in humans, a group of researchers conducted a randomized, triple blind, placebo controlled experiment. This study included 100 women who were experiencing insomnia. The subjects were randomly assigned to either the treatment group (receiving 530 mg of valerian extract in each supplement) or the placebo group. All participants took their assigned supplement twice each day. The treatment group showed a significant improvement in quality of sleep when compared to the placebo. (4)

Passion Flower Extract

This ingredient has been used in Native American medicine as a treatment for many different conditions. People use it in supplementation to calm the mind, soothe your stomach, reduce anxiety, and improve sleep. The lack of research done on this supplement makes it difficult to determine if it’s safe and/or effective. But, a few studies have been conducted to test the effects of passion flower on sleep.

A group of researchers wanted to test the effects of passion flower sleep in humans due to its lack of clinical trials. They conducted a double blind, placebo controlled experiment with 41 human participants. Subjects were given either passion flower tea or a placebo tea for a week. Only six participants showed significantly improved sleep quality when compared to the placebo tea. These initial findings show the potential use of passion flower tea to help improve sleep in some subjects. (3)


Melatonin is a natural chemical created in the brain. It is one of the most common supplements used to help people get better sleep. The brain creates serotonin then uses it to make melatonin when it is dark. Some people like to take it in supplementation to induce sleep on command, instead of waiting for the brain to naturally produce it.

In one study, researchers tested the effects of melatonin supplementation in patients with insomnia. A total of 50 participants with insomnia were included in this randomized, double blind, placebo controlled experiment. Subjects were given either a placebo pill or a melatonin supplement every evening for 14 days. Researchers found a significant improvement in the sleep of those taking melatonin. (1)

Vitamin D3

Everyone loves the sunshine vitamin. It gained this nickname because of our skin’s ability to absorb sunlight and produce vitamin D. We love to see this ingredient in supplements because deficiencies are very common, so it is important to make sure you are getting enough of it. Not only will it help you get your daily needed intake, but increasing vitamin D levels is a great way to boost weight loss.

A review of randomized, controlled studies was created to find the effects of vitamin D supplementation on weight loss. Eleven studies were selected that focused on the effects of vitamin D on overweight and obese individuals. By investigating these studies it was found that vitamin D supplementation can decrease BMI and weight circumference, but did not significantly affect weight loss. (8)

How Does This Formula Compare To Other Formulas?

Night Time Fat Burner is hard to categorize and compare to other weight loss supplements. This supplement can’t really be used for day time use or night time use because it contains both stimulants and sleeping aids. 

A lot of the ingredients in this formula don’t have much of an effect on weight loss and are more aimed towards sleep. This is something that is good to see in a plain sleeping supplement, but for a supplement that is supposed to be designed to burn fat, it is a bit of a disappointment. We would have liked to see a more thought out ingredient list with less side effects. 

How Much Does Envy Nutrition’s Night Time Fat Burner Cost?

You can purchase Night Time Fat Burner from many different websites across the internet. You can also find it at the official Envy Nutrition website, Amazon, and Walmart. The price differs depending on where you buy it from, but it typically costs around $20-$30.

Envy Nutrition’s Night Time Fat Burner Pros:

  • 60 day supply
  • Made in the USA
  • 60 day money back guarantee

Envy Nutrition’s Night Time Fat Burner Cons:

  • Contains conflicting ingredients
  • Causes a plethora of side effects
  • Any online posts, videos, or pictures can be exploited because of Evolution Nutrition’s “Your License To Us” policy that can be viewed on their website.

Side Effects:

Although most of the ingredients in this formula are safe to consume, people have found quite a few negative side effects from its use. The most typical side effects are sleeping problems, night sweats, dizziness, grogginess, increased hunger, and weight gain. Luckily, customers have found that after they stopped taking this supplement, the side effects went away.

Some other side effects from the ingredients are rapid heart rhythm, nausea, vomiting, impaired cognitive function, loss of coordination, lower protein digestion, reduced nutrient absorption, gas, diarrhea, bloating, constipation, and more. Like with all supplements, if you choose to take Night Time Fat Burner it is important to be cautious and pay attention to potential side effects it may cause.

What Are Customers Saying?

The customers who have used this supplement found that it causes sleeping problems, increases weight gain, gives you night sweats, induces dizziness, causes grogginess, increases hunger, and for a lot of customers the use of this product had no positive effects. 

There were also mentions of very poor customer service. Customer service is very important for anything you buy, but especially for supplements. Plus, if you want to take advantage of the money back guarantee, it is very important to be able to contact the company and get a response.

Why Is It Important To Have A Weight Loss Aid?

Having a weight loss aid can help you achieve real weight loss. Losing weight on your own is very difficult and oftentimes its difficulty causes people to give up. We want to see you reach your goals. This is why weight loss supplements are so important to us. But, not every diet pill can help you do that. It is very important to find a real, high quality supplement to help you get to where you want to be.

Envy Nutrition’s Night Time Fat Burner Bottom Line:


Just by a surface glance you can tell that not a lot of thought was put into this formula. It contains caffeine and melatonin which are the two most popular ingredients for staying awake and falling asleep. This conflict between ingredients makes it hard to use at any time of the day. We suggest looking at supplements that have a high quality and effective formula.


Although this supplement is cheaper than most, the lower cost can be seen in the quality of this product. It only contains about 500 mg of product in each capsule, and almost all ingredients are added in with unknown amounts. The ingredients are in a proprietary blend, which is sometimes used to protect the formula from being stolen, but in this case it looks like a way of hiding large amounts of cheap ingredients. 


This supplement won’t give you the best results, but some people have found it to be somewhat effective. A lot of customers have experienced a lot of unwanted side effects including weight gain, increased appetite and more, which are exactly what you don’t want when taking a weight loss supplement.

We like to stay as honest as possible and from what we’ve found in this supplement, the likelihood of it working isn’t great. Some people have used it and found it to be helpful, but there’s really only a couple of ingredients that actually affect weight loss. 

Night Time Fat Burner has ingredients that contradict each other, poor customer service, and has given users overall bad experiences. While it does have a couple good ingredients, they don’t balance out the negatives. 


Is there a money back guarantee?

Yes, this supplement comes with a 60 day money back guarantee which meets industry standard. Unfortunately, that’s the only information that is given about this policy. We prefer companies that are open and honest about their money back guarantee. 

How long does each bottle last?

Each bottle lasts a full 60 days, which is great to see in a supplement. 

Is Night Time Fat Burner safe?

This is a safe supplement, most of the ingredients in this night time diet pill are fairly gentle. 

Can I sign up for an autoship program?

Yes, you can sign up to have it automatically shipped and have the payments automatically taken out of your account when you purchase it from amazon or the official website. These methods are highly not recommended.

Is Night Time Fat Burner Vegan Friendly?

No, this supplement is made with a gelatin capsule.
