Fat burning supplements are a hot topic in the health and fitness world right now, and I regularly encounter people that either love them or simply despise them. And I can completely understand why so many people think they are magic pills with no actual magic.

Snake oil is the term that comes to mind.

We’ve looked into conventional fat burners in an article for men and another geared for women, but I also did some extensive research into some of the reportedly best nighttime fat burners. There were a lot of useless products as expected, but I did find some that had very positive reviews.

But always jumping to that conclusion is not always fair, because there are some nutritional supplements that actually work well.

So I dug deeper, did some intensive testing on about 35 products, and I have all the results of the best nighttime fat burner for you here.

Our Best Nighttime Fat Burner Recommendations (2021 Updated)

1 - Phen24 (Editor's Choice)


Your metabolism tends to slow as you age, making it easier to put on the extra pounds and harder to shed them.

One product that aims to address that is Phen24, a supplement that claims to “fuel” your metabolic rate round the clock.

The brand’s unique weight loss system involves a two-part process.

They offer day and night capsules that contain distinct ingredients that boost your metabolic function according to your sleep and wake cycle.

During the day, Phen24 enhances your body’s thermogenesis (heat production) and resting metabolism to burn fat quickly and support weight loss.

At night, this supplement works to decrease your cortisol levels, promote a feeling of calmness, and help curb your sugar cravings, so all the hard work you’ve been putting in won’t go to waste.

  • Guarana extract: 100mg
  • Glucomannan: 500mg
  • Cayenne pepper: 20mg
  • Unique system that works day and night to increase metabolism
  • Claims to decrease cortisol levels and promote feelings of calmness
  • Claims to help curb sugar cravings
  • Made with all-natural ingredients
  • Contains caffeine, which might cause jitters

These pills contain no stimulants, so you’re less likely to experience sleep interruptions by taking them in the evening.

2 - Lean PM

This fat burner was recommended to me by a colleague at the gym where I work, but before I went to test it, I had a look at the online Lean PM reviews.

In quite a few fitness forums and Facebook groups, I found a lot of people saying it worked well as a sleep aid, mainly due to the 5 mg of melatonin, the most impressive on this list of best nighttime fat burners.

There were also positive comments about its increased fat burning ability. Combined with a healthy diet and workout routine, it does seem to help a lot of people in burning fat. You can watch this video review:

  • Vitamin B6: 10mg
  • Magnesium: 150mg
  • L-Theanine: 200mg
  • Claims to promote better sleep cycles from REM to deep sleep
  • Contains proven fat burning ingredients and metabolism boosters
  • Suppresses your appetite, so you don’t wake hungry
  • Added vitamin B6 and magnesium
  • A higher dose of magnesium would be good

Personally, I found that it did help suppress my appetite (possibly because of the green tea content), so I didn’t feel hungry while going for my morning run before breakfast. The only downside I found is that it doesn’t give you 100% of your daily magnesium needs, which would be a nice bonus.

3 - Sheer Shred PM

Sheer Shred PM fat burner

Another product that promotes being an effective fat loss supplement is Sheer Shred, and again, the focus is on boosting your metabolism while you rest.

One of the ingredients that stood out for me was the kidney bean extract, which has shown to be effective at delaying digestion of carbs, which limits the number of calories you absorb. Another one is L theanine which aids in restful sleep.

A lot of online reviews highlighted that this fat burner didn’t just promote better sleep cycles, but also made people fall asleep faster.

  • Ginkgo Biloba: 70mg
  • Melatonin: 100mg
  • Lavender: 100mg
  • Contains white kidney bean extract to slow down carb digestion
  • Doesn’t hide behind a proprietary formula
  • Promotes better REM and deep sleep cycle through melatonin and lavender extract
  • Proven natural ingredients that can help with some bonus fat burning
  • A higher dose of melatonin would be better

Personally, I would have liked to have seen a slightly higher dose of melatonin, and I wouldn’t rate it as the best nighttime appetite suppressant. If that’s what you need, then option 1 above is the better choice. I have to point out the kidney bean extract and l theanine content though, they're some of the finest ingredients for an effective nighttime fat burner.

White bean extract may be helpful for weight loss because the beans produce substances that interfere with an enzyme called amylase that is necessary for the breakdown of carbohydrates, which are one of the main sources of calories in many diets.

4 - T6 Star6urn PM

T6 Star6urn PM Fat Burner

This overnight fat burner from T6 was the first one I found with garcinia cambogia, which has a great track record of working as an effective fat burner.

I personally found it worked pretty well as a sleep aid, mostly from the point of view that I got to sleep pretty fast.

I found quite a few athletes mentioned in forums that they thought it was the best nighttime recovery supplement, especially on high-intensity workout days.

  • Magnesium: 30mg
  • Green Coffee: 250mg
  • Melatonin: 5mg
  • Good to see garcinia cambogia on the list with proven fat burning capability
  • Provides some magnesium to help with muscle relaxation
  • Lots of reviews say that it works well as a sleep aid
  • Not stimulating despite containing green coffee bean extract
  • There’s really no need to put fancy names on natural products

I’m not sure I would go that far, but the added magnesium does help with muscle relaxation, which can help with recovery.

If you want your body to recover faster, check our best magnesium supplements list.

With all the good things to say, I did find it a bit annoying that the company tries to market simple and natural ingredients under fancy names like KSM-66 and InnoSlim.

Just keep it honest when it comes to fat burning products.

5 - Naturewise Nighttime Slim

Naturewise Nighttime Slim Fat Burner

Naturewise is my next recommended nighttime fat burner pill, which does balance the sleep aid and fat burning ability quite well.

While I wasn’t able to prove or measure its fat burning ability, the company claims that it will help you burn about 116 kcal while sleeping.

From the reviews I looked into, there were two common highlights of this fat burner. First, many people said they wouldn’t wake up hungry, which helped them increase their fasting periods that little bit more.

  • Slimming blend: 400mg
  • Relaxation Blend: 355mg
  • Claims to help burn an extra 116 kcal while you sleep
  • Works well to suppress appetite
  • Doesn’t cause an overly hot feeling
  • Free from most common allergens
  • Hides behind a proprietary blend

Secondly, they didn’t tend to get that hot feeling that some other fat burning products can cause. The only real downside is that the company hides behind a proprietary blend, so you don’t really know how much of each ingredient you’re getting.

6 - Havasu Night Time Weight Loss Pills

Havasu Night Time Fat buner Weight Loss Pills

Havasu was a company that I wasn’t really familiar with, so I decided to do some extra research and talk to a dietician about them. It turns out, they are actually a very reputable maker of supplements.

This fat burning one is actually rather simple when it comes to the ingredients, but the company does keep the exact amounts a secret.

I tried it for 2 weeks and would agree with many online reviews that it does help with sleeping, even if there is noise around your home.

  • Vitamin D3: 30mcg
  • Rest & Reset Blend: 500mg
  • Fat burning through simple and proven ingredients
  • Contains the hormone melatonin to make it easier to get to sleep
  • Limits nighttime food cravings
  • You only need to take one pill
  • Another brand that has a proprietary blend

While I never really get cravings for snacks, quite a few comments mentioned that it does seem to suppress their appetite.

7 - Modern Man PM Fat Burner

Modern Man PM Fat Burner

As the name suggests, this is one of those fat burning supplements that is specifically designed for men.

This means the dosage is higher than what women need, but for men, it will contain everything important in the right quantity.

Personally, I didn’t find that taking the fat burner before bedtime made me get to sleep quicker, but I did find that I had a more relaxing night feeling more recovered in the morning.

  • Glycine: 500mg
  • Melatonin: 5mg
  • L-Theanine: 200mg
  • Specifically designed for men to boost testosterone
  • Contains ashwagandha which helps with muscle recovery
  • No outrageous claims of massive weight loss
  • Claims to reduce the stress hormone cortisol
  • Doesn’t seem to work as well for getting you to sleep

Some people said they used sleep monitoring apps and that they did measure a better cycle between REM and deep sleep. A few reviewers also pointed out that it worked well to reduce stress levels after a busy day at work. Overall, a pretty good option.

8 - RevBurn

RevBurn Fat Burner

So, we’ve covered a night time fat loss product designed for men, now it’s time to list one for women, and that’s exactly what RevBurn has done.

The dosage of the active ingredients will be lower, and the ingredients were chosen as they work best to burn fat for women.

One thing I saw in a lot of the reviews is that many people said it worked well as an appetite suppressant thus resulted to significant fat loss.

It also contains natural ingredients that improve sleep cycles and relaxation. It also boosts your metabolism to maximize the fat burning effects.

You can also use this metabolism tracker called Lumen.

  • Energy & Focus Blend: 450mg
  • Thermogenesis Blend: 40mg
  • Specifically formulated for women
  • Many positive comments about appetite suppression
  • Promotes deep sleep
  • Makes a good combination with the company’s day time fat burner
  • Proprietary blend hides the exact ingredient amounts

Some users reported to have headaches when waking up after taking this supplement. Try and see it for yourself.

9 - BPI Night Burn

BPI Night Burn

Night Burn is the last night time fat burner product on my top recommendations list, and it is one of the more popular options available.

Many users report that it works pretty well as a sleep aid to get a more relaxed and restful sleep.

For fat loss, it seems to work best when taken during a fasting period, so try to not eat too late in the evening to get the best results. You can also save some money by ordering the bulk container.

  • Good source of vitamin D
  • Positive reports of better REM and deep sleep
  • Targets fat storage well, especially during fasting periods
  • Available in bulk containers to save some cash
  • Another hidden proprietary blend

However, I personally found that the recommended dose of one pill wasn’t quite enough, so keep that in mind when you compare prices to other options above.

Nighttime Fat Burner Benefits

Nighttime Fat Burner Benefits

The obvious benefit of these fat loss supplements is that they aim to help you lose some weight and burn fat while you rest. But there are a few other benefits that you can experience.

1. Promote Better Sleep Cycles

All of the above products work as a sleep aid in that they will help you fall asleep faster and get into a better and more consistent cycle. Whether you have a lack of sleep due to stress levels or noise at home, this is one of the top reasons to consider taking them. (1)

2. Don’t Wake Up Hungry

Some of these supplements will work quite well to regulate your blood sugar and keep you feeling full for longer. You’ll avoid food cravings and the need for a huge breakfast.

3. Cortisol Reduction

Cortisol is a hormone that is directly linked to stress levels. (2) If you have a busy personal and professional life, then cortisol can interfere with your sleep. Any reduction will help you feel more rested.

4. Thermogenic Effects

One way to lose weight without exercising is through thermogenic, metabolic effects. Essentially, they raise your body temperature slightly, and this is achieved by burning more energy. Fat loss is achieved faster through thermogenesis.

5. Boost Those Growth Hormones

Some of the above supplements will also help with muscle recovery by increasing testosterone and, indirectly, growth hormone levels. This can give you that small edge to bulk up more.

How Do Thermogenic Fat Burners Work?

man and woman body

Thermogenic fat burners work by slightly raising your core body temperature.

In order to do this, your body has to increase its metabolic rate, and that means burning more energy. But then, it's good to know which metabolic type are you.

Now, if you have loaded up on sugar and carbs, then your blood glucose will be lowered first.

But if you take these supplements before exercising or while on a limited calorie diet, then your body will have to resort to stored body fat as a source of energy.

Do Nighttime Fat Burners Work?

people working out

Yes, nighttime fat burners can work to help you burn fat, as long as they are taken as part of a balanced diet with plenty of exercise.

They are not a magic pill that will allow you to snooze away unwanted fat, and if you come across such claims in advertising, then I suggest you keep well clear of it.

There are a lot of crap snake oil products out there, but the ones listed in the above nighttime fat burner reviews do work reasonably well.

If you want to burn away some extra calories and melt away some love handles, then you can get to your fat loss goals quicker by taking them regularly.

Any Side Effects?

No, for the most part, nighttime fat burners don’t have any side effects, unless you have some sort of allergies to the ingredients or you take too large a dose.

Unlike the daytime equivalents that are reliant on stimulants like caffeine from green tea extract, these types will actually have the exact opposite effect. They will make you slightly sleepy, so just keep that in mind.

Some of the products listed here have a form of green tea or green coffee bean extract ingredient, but they are mostly contained in minimal amounts to burn fat and not as a stimulant.

You don’t want to be falling asleep at your desk at work 😉

Buyer's Guide - What To Look For

beans, magnesium, and berries | best nighttime fat supplements ingredients

When it comes to a good nighttime fat burner, there are some ingredients you want to look for on the labels. Here are the most common ones:

  • Green coffee bean extract: a natural ingredient that helps to suppress your appetite (3)
  • Raspberry ketones: promote faster breakdown of fatty tissue
  • L-carnitine: allows more fatty acids to be transported to muscle cells
  • Magnesium: Helps to relax muscles
  • White kidney bean extract: lowers how many carbs are digested

Whatever product you ultimately choose, just make sure you don’t see any hint of stimulants or energy boosters. While you do want to burn more energy, you don’t want your body to ingest more.

Although many people take L-carnitine as a way to speed up weight loss and fat burning, carnitine benefits include enhancing brain function, preventing muscle damage, regulating blood sugar, and increasing endurance as well.

When is the best time to take nighttime supplements?

The best time to take a nighttime fat burner is about 30 minutes before you go to bed. This gives your stomach some time to absorb the ingredients, and you can start winding down your brain as well.

How much nighttime fat burner should I take?

You should only take as much nighttime fat burner as is suggested on the label. Taking too much can cause some stomach upset and drowsiness.

I would suggest not taking more than 5 mg of melatonin, which is what you’ll get with most products above. Look into magnesium and l theanine content as well (sleep aid ingredients) as they may cause small digestive issues in some people.

How long do nighttime fat burners take to work?

Nighttime fat burners usually take about 30 minutes to start working. This does depend on your digestive system, but many of the ingredients are very easy and quick to absorb and start working their magic.

What helps burn fat while you sleep?

Raspberry ketones and L-carnitine help to burn some extra fat while you sleep. They do this by helping your body target fat for energy production and by transporting more fatty acids to your body cells.

Will I still be able to sleep well if I take nighttime fat burners?

Yes, you will still be able to sleep well if you take nighttime fat burners because the majority of them contain ingredients that help you get to and stay asleep with ease. With a better deep and REM cycle, you’ll feel much more rested in the mornings.

Can nighttime fat burners make you gain weight?

No, nighttime fat burners cannot make you gain weight because they will generally support calorie and fat burning. If you do notice some extra pounds on the scales, then you’ll need to look at some other aspects of your lifestyle to burn fat.

Are nighttime fat burners dangerous?

No, nighttime fat burners are not dangerous, as long as you don’t take too many and stick to taking them at home before you go to bed. They can make you feel a little drowsy, so you wouldn’t want that to happen while you’re at work or driving.

Can I take nighttime fat burners if I’m also taking daytime fat burners?

Yes, you can take nighttime fat burners if you’re also taking daytime fat burners.

There are actually quite a few products available that are designed to complement each other to maximize your weight loss and burn fat.

When coupled with a healthy diet and regular exercise, supplements can really help you get to your goals a lot quicker.

The top nighttime fat burner that stood out above all the products reviewed is Phen24. I like that it’s both a day and night time supplement that works 24/7, which means you also get to lose weight faster and, hopefully, keep it off forever.

This metabolism booster could be a great option for you no matter your dietary preferences, as it’s 100% vegan and vegetarian friendly.
