It’s no secret that fat burners are a favorite option for supplementing diet or exercise. What you may not know is it’s possible to take your weight loss goals to the next level even while you sleep.
Nighttime fat burners are growing in popularity due to their ability to boost metabolism and burn calories all while supporting a good night’s rest. If you’ve been putting in the hard work during your day, there’s no reason the results should have to stop while you sleep.
Assembled below are five of the top nighttime fat burning supplements on the market for both men and women.

Best Natural Ingredients
Best Proprietary Blend
Best for Active Individuals
Phen24: Best 24-Hour Support
Phen24 is manufactured by Wolfson Brands (UK) Limited, a company whose trusted name has been leading the industry in producing high quality, researched supplements for over 10 years (1).
Phen24’s formula is split into two parts, a daytime and a nighttime supplement, in order to help your body shed pounds 24 hours a day. Phen24 was created with ingredients to optimize your metabolism and heighten thermogenesis so your body can burn more calories, even while you sleep. Additionally, both blends include ingredients that nourish your brain and support nerve activity so you can function at your best.
Containing 10 clinically tested ingredients, the nighttime blend is the real powerhouse of this duo. Phen24 claims that its nighttime formula will reduce stress, curb cravings, promote brain function and quality sleep all while aiding your body in the natural restorative processes that occur during rest.
Phen24 only includes natural ingredients with little to no known side effects. However, the daytime supplement has caffeine and could affect your ability to sleep depending on the time it is taken.
Lean PM: Best Rest and Recovery
Lean PM is manufactured by Jacked Factory. This company’s top priority is to over-deliver on value and customer service shown by having the highest rated supplement on the list.
Lean PM labels itself as a nighttime fat burner and sleep aid. Many of its ingredients have been shown to support restfulness and healthy sleep patterns at night while improving your mood and brain function during the day. Unfortunately, Lean PM’s blend only includes one ingredient that directly helps burn fat, green tea extract.
What this supplement may lack in fat-burning power, it makes up for in recovery. While you sleep, Lean PM’s vitamins, antioxidants, and amino acids work to build lean muscle, form strong bones, and promote a clear mind so that your body can be in great shape to accomplish its goals.
Lean PM is made up of only 6 natural ingredients so side effects are unlikely. The company does recommend taking 1 pill (half a serving) for the first 3 days to assess how your body will tolerate Lean PM.
Sheer Shred PM: Best Natural Ingredients
Sheer Shred PM is manufactured by the sports nutrition company Sheer Strength Labs. This uniquely blended supplement claims to help burn fat, boost recovery, and encourage restorative sleep.
With extracts like Hops and White Kidney Bean, Sheer Shred PM may lead to a decrease in stubborn body fat and prevent the formation of new fatty tissue all while helping you retain lean muscle. Sheer Shred PM also includes other herbs and amino acids that promote more restful sleep.
While Sheer Shred PM includes some highly effective ingredients, research suggests that other elements like Dandelion Extract present inconclusive results when it comes to their weight loss effects. This has left some users wondering why Sheer Strength Labs includes these ingredients in their blend.
Sheer Shred PM is made up of all natural ingredients that have no known side effects. However, note that this supplement uses a gelatin capsule which is not considered vegetarian friendly.
NightTime Slim: Best Proprietary Blend
NightTime Slim is manufactured by NatureWise. With a mission to promote health and inspire wellbeing, NatureWise is committed to producing quality products that have a positive impact on their customers.
NightTime Slim claims to promote sleep continuity and burn fat by encouraging your body’s thermogenic activity and metabolic functions. These claims seem to be backed by effective weight-managing extracts like Coleus Forskholii and Cayenne Pepper Fruit along with four additional ingredients that contribute to a good night’s sleep.
Something to note about NightTime Slim’s formula is their use of proprietary blends. A proprietary blend is a group of ingredients in which each ingredient is listed but their exact amount or potency is not (3). This could be a problem for some users who want to know exactly what they’re receiving from a product.
NightTime Slim is not known to have any dangerous side effects but does include caffeine which could affect your ability to sleep.
Modern Man PM: Best for Active Individuals
The Modern Man PM fat burner is manufactured by Modern Man. With the slogan “Rest for the Relentless,” Modern Man PM was created to help individuals who put the tough work in throughout the day maximize their restoration during the night.
Modern Man’s approach to fat burning revolves around relieving stress. They believe that stress is one of the largest obstacles keeping people from realizing their weight loss goals. With ingredients like Ashwagandha, Modern Man helps you to relax by supporting adrenal health and regulating cortisol (stress hormone) levels.
Additionally, Modern Man PM claims that its ingredients can promote restful sleep while working to increase your lean muscle mass and strength.
Modern Man PM is formulated with all-natural ingredients and is unlikely to produce negative side effects. The company also explains that, despite its branding, the supplement is safe for women to take.
How Do Nighttime Fat Burners Work?
Nighttime fat burners have the tricky job of burning up calories while the body stays completely at rest. Most supplements accomplish this by implementing one or more of the following mechanisms.
It is a fact; your body needs sleep. Sleep is the time when your mind is recharged, your muscles are restored, and your body builds up energy to tackle the next day. Without restful sleep, your body cannot effectively accomplish its essential functions, which include using food for fuel instead of fat. Studies show that insufficient sleep can have harmful effects on metabolism and has even been linked to obesity (4).
This is what makes supplements that support restful sleep so popular and why companies have utilized them to improve fat-burning products. Some common ingredients used in supplements to promote sleep include Melatonin, L-Theanine, Gamma-Aminobutyric Acid (GABA), and L-Tryptophan.
When it relates to weight loss, Thermogenesis is described as “the metabolic process by which organisms burn calories in order to generate heat” (5). Foods that create this heat, thereby burning calories, are said to have thermogenic properties. Such foods are believed to boost metabolism, reduce appetite, and burn fat (6).
It is not surprising that companies want to implement these kinds of elements into their fat-burning products. Popular thermogenic ingredients include Cayenne Pepper Extract, Black Pepper Extract, and Caffeine. Thermogenic foods sound like a miracle solution to burning fat but it’s important to remember that they only add an extra edge to diet and exercise, and do not cause a dramatic drop in weight on their own.
Unhealthy levels of stress can be directly connected to weight gain. This is due to the stress hormone cortisol. Cortisol signals the release of glucose (sugar) into the bloodstream, providing your body with the energy it needs to escape and recover from stressful situations. This is helpful if you are trying to outrun a threatening dog or save a child from drowning, however, if you experience chronic stress and the signal never turns off, that much glucose becomes a problem (7).
Reducing stress is important for your body’s overall well-being and that includes weight loss. Ingredients that have been linked to stress relief include Green Tea and Ashwagandha.
The supplements mentioned in this article contain mostly natural ingredients and the chances of experiencing side effects are low but not unheard of. When introducing a new element into your digestive system it is possible to experience nausea, constipation, abdominal pain, or headache.
Keep in mind that supplements are not strictly regulated so it is important to check with your doctor if you have any concerns.
Each supplement mentioned above comes with unique strengths and weaknesses. We recommend evaluating your personal needs to determine what nighttime fat burner works best for you. Four out of the five recommendations also come with a money-back guarantee (excluding Modern Man PM) so you don’t have to be afraid to try them for yourself.
