If you’ve been trying to lose weight, you might have considered using a fat burner. It’s fine to add one into your routine, but be mindful that many fat burners contain stimulants that can affect your sleep.

Lean PM is a fat burner that claims to be free of stimulants. Instead, it claims that using this product can improve your sleep.

The following review will look at this fat burner and sleep aid in more detail. Is it really possible to lose fat while you sleep as it claims?

What Is Lean PM Night Time Fat Burner?

Lean PM Night

Using Lean PM Night Time Fat Burner promises to help you fall asleep faster, sleep better, and burn fat while you sleep.

It claims to be free of caffeine and other stimulants, so in theory, you should not encounter any jitters, headaches, or crashes that you would associate with diet pills that contain stimulants.

Its all-natural formula may work for both men and women, enabling both sexes to lose stubborn body fat, take control of night-time food cravings, and help you to wake up feeling refreshed, without the drowsiness associated with other sleep aids.

This supplement can help:

  • Promote fat burning
  • Relaxation
  • Mood enhancement
  • Deeper sleep

The product claims to be a fat burner, sleep aid supplement, appetite suppressant, and weight loss pill in one.

It is manufactured by a USA-based company called Jacked Factory.

The manufacturer claims that they work in a cGMP certified facility to ensure that the highest quality control guidelines are followed and the best quality and most potent ingredients used.

Ingredients Breakdown


One thing I would always say to look for when reviewing fat burners or any type of supplement is to ensure you can see what ingredients it contains.

Luckily for us, the Jacked Factory Lean PM bottle has a label and unlike other competitors we have seen it does not use a proprietary blend.

As there is no proprietary blend, we can see not only the ingredients used but also the dosage of each ingredient. This ensures we can see how effective this fat burner may be, and what effects it should have on us before purchase.

The ingredients found in Lean PM include:

Vitamin B6 (10 mg per serving)

avocados and bananas

Vitamin B6 is a water-soluble vitamin your body requires for several functions.

It cannot be produced by your body, so it must be obtained through food or supplementation.

There is evidence to suggest this vitamin can aid your weight loss efforts by:

  • Promoting a healthy metabolism. This vitamin is important if you are looking to burn fat as it helps contribute to a healthy metabolism [1].
  • Improving your fat to lean muscle ratio. Research has also found that this vitamin helps to improve your fat to lean muscle ratio. Helping to promote fat loss, while maintaining muscle mass [2].
  • Reducing tiredness and fatigue. Deficiencies in this vitamin can lead to anemia, with symptoms that include weakness, tiredness, and fatigue [3].

Epigallocatechin Gallate (EGCG) (300 mg)

EGCG is a catechin found in green tea and other plant-based foods. It acts as a potent antioxidant that can protect you against the cellular damage caused by free radicals [6].

Research has found that the catechins found in green tea can help you burn fat. Those who drink 2 cups of green tea daily were found to have lower fat percentage and weight than those who didn’t drink it [7].

Magnesium (150 mg)


his is an important mineral that your body needs to function properly.

It helps to produce energy, regulate your blood sugar levels, and will cause numerous necessary chemical reactions to occur.

Research has found that it may benefit your weight loss efforts by:

  • Reduces bloating and water retention [5]. Water weight occurs when fluid collects between your organs and skin tissue. This can leave you feeling bloated and uncomfortable.
  • elping to control insulin and blood glucose levels [4]. Insulin helps to convert the energy found in the food we eat into fat. Too much insulin will cause weight gain, so it is important that we take control of it.

The increase in the chemicals can help reduce stress and anxiety [8], so in theory, it should work to suppress appetite and cut food cravings.

5-hydroxytryptophan (5-HTP) is an amino acid produced naturally by your body.

It is used by your body to produce serotonin, which is important as low levels of this hormone have been linked with depression, sleep disorders, and weight gain [9].

5-HTP has been shown to suppress your appetite and aid weight loss [10].

Melatonin (5 mg)

Melatonin is a naturally occurring hormone produced by your body. It is secreted by the pineal gland in your brain and is responsible for regulating your circadian rhythm.

According to research, melatonin will help you fall asleep and can promote restful sleep [11].

It can also help to increase your metabolism, helping to increase fat burning and overall fat loss [12].

Bioperine (5 mg)

Black Pepper Extract

Bioperine comes from black pepper, and while it has negligible health benefits on its own, when it is added to other ingredients its benefits become well-known.

This ingredient increases the bioavailability of other ingredients [13], this means that it helps the other ingredients to work better.

So when added to a fat burner, it will increase fat burning, or when added to a sleep aid, it will help promote restful sleep.

Any Side Effects?

side effects

Despite claims that Jacked Factory Lean PM is safe and will not cause any side effects to occur when looking at its ingredients, there are certainly some worrying effects you should worry about.

  • Too much vitamin B6 can cause nerve damage and pain or numbness in your hands and feet. It is for this reason why you should avoid consuming more than 100 mg per day [14].
  • Magnesium is pretty safe, but in high doses may cause serious side effects that include low blood pressure [15].
  • EGCG has been linked to various side effects, including liver and kidney failure, dizziness, low blood sugar, and anemia [16].
  • Reported side effects of 5-HTP include heartburn, stomach pain, nausea, vomiting, diarrhea, drowsiness, sexual problems, and muscle problems.
  • Melatonin is generally safe for use, although it has been linked to mild side effects such as dizziness, headache, nausea, and agitation [17].

Alternatively, you can try out PrimeShred or PhenGold diet pills and see if they suit you.

User Reviews Of Lean PM Night Time Fat Burner

hand rating

Customer reviews of Jacked Factory Lean PM are pretty impressive, with customers saying some pretty nice things about this product.


For me personally, I found that PM Burner works marvels on my body. After a goof workout, I am finally sleeping better, have tons of energy tomorrow, and it has helped me burn some excess fat in the process. I have been taking them for more than two months and consider them a staple on my kitchen shelf for supplements. I highly recommend it for everyone trying to get in shape.


- Bernardo C, Amazon Buyer

5 years ago, I had a c-section and have struggled to lose the belly pouch ever since. However, Lean PM has helped me immensly - I am finally starting to see my waistline again. 5 years, folks! Not to mention it helps me relax and get lots of good night's sleep.


- Tiffany Prescott, Amazon Buyer

Not every customer is impressed with this fat burning supplement and sleep aid, however.

To be candid, I used these for about a month and it was so hard to wake up on time. I just felt tired constantly. There were even times I couldn't get up for work so I had to call in sick. Also, I am not sure if I lost weight. Maybe others have different reactions but for me, this was a horrible experience.


- Ashleigh, Amazon Buyer

This product is an absolute joke! I've read lots of fake reviews and actually believe there is no sleep-aiding benefit to these pills. I cannot sympathize enough with the misery this kind of melatonin dosage can cause. I work out 5 days a week, and wanted a supplement that helps burn stubborn belly fat - but ended up regreting it.


- Micaela Nawrocki, Amazon Buyer

For the best outcome, you should take two capsules 45 minutes before bed on an empty stomach.

Does Lean PM Contain Any Stimulants?

No. Lean PM does not contain any stimulants.

Does Lean PM Night Time Fat Burner Offer A Money Back Guarantee?

There is no money-back guarantee. According to the Amazon listing, if you are not completely satisfied with your final result they will “work to resolve your concern.”

Should You Buy Lean PM Night Time Fat Burner?

If you are looking for the best fat loss supplement without stimulants, then our review of Jacked Factory Lean PM suggests that it may be an option you want to consider.

Despite the impressive ingredients list, I believe there are some other superior product offering better results in general -- from fat loss to building lean muscles without the side effects.

I highly recommend PhenQ as it contains more powerful fat burning ingredients like capsimax, chromium, and caffeine.

It may not be specifically suitable for use in the night, but they offer much more of a benefit during the day when you need help from a supplement the most.

Other users have also found it effective for fat loss. The images here speak for themselves:
