What is Mav Nutrition Night Time Fat Burner

A weight loss supplement for men and women that you can buy online. It’s intended to function as a sleep aid and fat burner combined. Read some customer reviews

Mav Nutrition is a relatively new company. It’s only been in the health and wellness industry since 2017. Other than the fact that it appears to be operating out of offices in Florida, I was unable to find out much about the company at all.

Mav Nutrition doesn’t focus entirely on weight loss. It provides a range of products intended to support good health. Only three of them are intended for people wishing to lose weight.

The companies other products include, fish oil capsules, vitamin pills, and encapsulated digestive enzymes. The company even offers elderberry gummies intended to provide immune system support for kids.

As far the price goes, there’s not a lot to put customers off. Mav Nutrition Night Time Fat Burner is a cheap supplement to buy.

However, if you are a vegetarian or vegan, you need to be aware the capsule casing is made of gelatin and Mav Nutrition Night Time Fat Burner won’t be suitable for you.

What are the Benefits of Night Time Fat Burner?

According to the label on the bottle, Mav Nutrition Night Time Fat Burner does three things:

  • Assists relaxation
  • Natural sleep aid
  • Supports fat burning

That’s a trio of benefits I’d expect for a product like this. However, the sales blurb alleges it can do more:

Additional claims include:

  • Supports immune function 24-hours a day
  • Stimulant-free formulation
  • Helps improve body composition and post-workout recovery

How Does Night Time Fat Burner Work?

It May Support Relaxation and Rest

Some of the extracts in the Mav Nutrition Night Time Fat Burner formulation have a reputation for providing relaxation and helping with sleep.

It May Boost Metabolism

The only ingredient that may have the potential to help with fat burning is green coffee bean extract. However, although lots of claims are made for its ability to boost metabolism and support fat burning, there’s a lack of reliable research.

If green coffee bean extract can increase metabolism, the body will burn more calories.

Anyone who has already created a calorie shortage in their bodies via diet and exercise may lose weight a little faster due to this because the calorie deficit will increase.

This will necessitate the need for the body to pull extra energy from its stores of fat.

There are several other diet pills that offer the night time metabolism boosting approach.

It May Provide Additional Benefits

As for the claim that Mav Nutrition Night Time Fat Burner will support immune function, it can be supported by the presence of Vitamin D.  Is it really a stimulant-free product though? That one is a bit of stretch.

Although the formulation contains no added stimulants, green coffee beans contain caffeine. They don’t contain as much caffeine as roast coffee beans, but it’s still a stimulant.

Improve Body Composition

The final claim Mav Nutrition is making is that the formulation will improve body composition and post-workout recovery. In theory, that’s supportable.

People who use any brand of metabolism-boosting weight management supplement alongside diet and exercise should see improvements in body composition. This will be mostly due to diet and exercise though. All the supplement will do is help them to burn a little extra fat.

Will Mav Nutrition Night Time Fat Burner aid post-workout recovery? If it can genuinely encourage better quality sleep, it may help a little in this regard.

Sleep is the body’s downtime. It’s when the body carries out a lot of its cellular repairs. Levels of human growth hormone (HGH) also become elevated during sleep, which further enhances healing and growth.

What’s the Best Way to Use Mav Nutrition Night Time Fat Burner?

The dose is one capsule per day. This must not be exceeded unless a health-care professional suggests otherwise. It seems obvious the best time to take the capsule will be at night but if there is an optimum time Mav Nutrition neglects to say when.

The company does make a point of stressing the fact that its product should not be seen as a magic pill. It suggests customers use the product in conjunction with a suitable diet and exercise program.

Additionally, Mav Nutrition issues a warning that the product is not for women who are pregnant or nursing a child, for anyone who has a serious medical condition, or for people who would need to use it alongside prescription medication.

Ingredient Profile

Supplement facts of Mv Fat Burner
Supplement facts

Each capsule provides:

  • Vitamin D (30mcg)
  • Rest and Reset Blend (500mg)

The Rest and Reset Blend consists of eight ingredients included in unspecified amounts.

  1. White Kidney Bean Extract Powder
  2. Green Coffee Bean Extract
  3. L-Theanine
  4. L-Tryptophan
  5. Valerian Root Extract
  6. Lemon Balm Extract
  7. Passion Flower Extract
  8. Melatonin

What Do the Ingredients Do?

Vitamin D

Vitamin D is a fat-soluble vitamin. You can obtain it from your diet by eating certain fats. Your body can also manufacture it in response to sunlight touching the skin.

As with any other nutrient, Vitamin D serves multiple roles within the body. Some of the things it does include maintaining the health of bones and teeth.

Vitamin D also has a role to play in cardiovascular and mental health. Another thing it does is support immune function. The dose here is about right for a supplement of this kind. However, the presence of Vitamin D in the Mav Nutrition Night Time Fat Burner formulation will probably offer the most benefit to people who are Vitamin D deficient. It won’t do a lot for anyone else. (

Rest and Reset Blend

It’s impossible to predict that value of this blend because the ingredient ratios are withheld.

However, let’s take a look at the eight inclusions one by one and see what kind of benefits they are associated with.

1. White Kidney Bean Extract Powder

White kidney bean is a popular carb-blocking ingredient. It’s a strange addition to a formulation such as this.

I say it’s a strange addition because carb blockers reduce calorie intake by hampering the body’s ability to digest carbohydrate. This is a nighttime formulation. If you are on a diet, you won’t be eating at night. Midnight feasts and weight loss are not a winning combination.

To be effective, white kidney bean requires quite a high dose. One study that supports its abilities as a carb blocker involved doses of 445 mg per day. In some studies, the dose was double that or more.

The entire Rest and Reset Blend is only 500 mg. Unless it’s predominantly white kidney bean there is not going to be enough. On the other hand, if the blend does provide 445 mg or more, the inclusion rates for many of the other ingredients will be too low.

2. Green Coffee Bean Extract

Green coffee beans provide a compound roasted coffee beans do not. It’s called chlorogenic acid and it’s allegedly a metabolism booster and fat burner.

Thanks to an endorsement on the Dr. Oz Show, green coffee bean products were once all the rage but there are doubts about its value. Experts agree there’s a need for more study.

One review of some human studies suggests green coffee bean may help with weight loss. Unfortunately, the data shows the amount of weight lost was not much. Additionally, the studies were poorly designed and not conducted over a sufficiently long period of time. (

3. L-Theanine

L-Theanine is an amino acid. You can get it by drinking green tea. Research shows it can be good for providing relaxation without causing drowsiness.

L-Theanine may also help reduce anxiety and stress. Its abilities are a match for a formulation such as this, but good results require quite a high dose. Some supplements provide a couple of hundred milligrams or more.

4. L-Tryptophan

Another amino acid that’s sometimes added to supplements.  Your body uses L-Tryptophan to make proteins and other important molecules, some of which support restful sleep and may have a positive effect on the mood.

Research suggests supplementing with L-Tryptophan may increase melatonin and serotonin levels and help with sleep. However, one study involved doses of 1-5 grams of L-Tryptophan. The dose here cannot possibly be that high. (

5. Valerian Root Extract

Valerian is a herb that been used as a sleep inducer since ancient times. Research shows it provides compounds that inhibit the breakdown of GABA in the brain. This calms the mind in a similar manner to the drug Valium.

Although research suggests valerian root can help provide restful sleep it also suggests 400-900 mg is the optimum dose. Once again, the amount here is unlikely to be nearly that high.

6. Lemon Balm Extract

Lemon balm is a herb that comes from the same family as mint. It’s traditionally used for improving mood and cognitive function.

Lemon balm appears to be good for relieving stress and anxiety. It may be a natural remedy for insomnia as well, but many studies involve doses of 300-600 mg per day.

7. Passionflower Extract

Some studies suggest passionflower extracts may be good for banishing anxiety and insomnia. However,  the National Center for Complementary and Integrative Health (NCCIH) states further research is needed.

8. Melatonin

This is a hormone that helps govern the desire to sleep and wake up. Your body manufactures it in the pineal gland. There are two types available for supplements. One is synthetic. The other comes from animal pineal glands. The form used here could be either one.

The value of melatonin supplements as a sleep enhancer is debatable. Although some studies support their use, others do not. (

Are There Any Customer Reviews?

MAV Nutrition Night Time Fat Burner is a popular diet pill on Amazon and customers have left more than 1,000 reviews.

Most of them are good and suggest the product supports restful sleep, reduces cravings, and help with weight loss.

Unfortunately, there are doubts about how reliable the customer reviews are likely to be.

Negative Reviews

The alarms bells began ringing when I read a review from a customer stating it was possible to get a free bottle of Mav Nutrition Night Time Fat Burner in exchange for a favorable review.

Then I found a review from a customer who claims the company prompts customers to write their reviews before they even receive the product.

Free bottles for good reviews

I responded to this revelation by using the Fakespot analysis engine to check the quality of the Amazon customer reviews.

The results suggest there could be some deception and indicate only 76.2% of the reviews are reliable.

Despite the prevalence of Amazon 5-star reviews, the Fakespot analysis states the reviews generally have a neutral sentiment and points out the review content quality is low.

Is There a Risk of Side Effects?

A lot of customers complain using the pills made them feel unwell. In fact, I was quite surprised to see such a variety of side effects mentioned in customer reviews.

Reported side effects include:

  • Feeling groggy the next day
  • Difficulty getting out of bed
  • Headaches
  • Heart palpitations/racing heart
  • Nightmares
  • Cold symptoms
  • Nausea
  • Bloating
  • Feeling light-headed

It’s difficult to say why Mav Nutrition Night Time Fat Burner could cause the kind of side effects some customers say it does.

However, looking at the side effects some customers report, and bearing in mind the doubts about the quality of some of the positive reviews, I strongly suggest you seek professional medical advice prior to using this product.

Hit or Miss? (Can You Lose Weight with This Night Time Fat Burner?)

Mav Nutrition Night Time Fat Burner offers theoretical value as a sleep aid because many of the ingredients have a reputation in this area. However, the inclusion rates are likely to be too low.

Green coffee bean extract may allow the formulation to function as a fat burner too and the presence of Vitamin D has the potential to offer value to people who are deficient in this important vitamin.

The truth is, there is no way to know what Mav Nutrition Night Time Fat Burner can do because inclusion rates are important ingredient information and they aren’t there.

Many customer reviews suggest the product helps with weight loss. Even more suggest it aids sleep but can the reviews be relied upon?

Certainly, this is a product that has a reputation for causing side effects. That’s not a strong selling point.

Purchasing Options and Considerations

Although it’s possible to buy Mav Nutrition Night Time Fat Burner directly from the Mav Nutrition Night Time Fat Burner website, the company also distributes its products via Amazon.

As is often the case, buying via Amazon allows customers to get the same pills for a slightly better price.

At the time of this review, the Amazon price was just under $22 per bottle. There was also an option to buy via “subscribe and save.” Doing so knocks a dollar off the price but subscribe and save is a poor fit for this product.

There are 60 capsules per bottle and the dose is one capsule per day. Why would anyone need to get a new bottle every month?


The Mav Nutrition website doesn’t mention a money-back guarantee, but the Mav Nutrition Night Time Fat Burner sales page at Amazon does. It states there is a “lifetime” guarantee.
