Lean PM review
Lean PM Night Time Fat Burner

Reputable brand.
Some good ingredients.
Not expensive.

May cause side effects.
Not the strongest formula.

An ‘OK’ fat burner in our opinion. The problem is there are several products that we would recommend over and above.

Take a look at our top choices of fat burner

What is Lean PM?

Made in the US by Jacked Factory. The company offers several other health and wellness supplements as well including some for people who like to do sports.

Jacked Factory claims Lean PM Night Time Fat Burner is the “best fat loss supplement without caffeine or other stimulants.”

That sounds good but there is no evidence to back this statement up.

There are many non-stimulant fat burners available including a few that are specifically intended for use before bed.

Lean PM Night Time Fat Burner is hardly one of a kind.

Lean PM Night Time Fat Burner (Alleged) Benefits

Jacked Factory makes many claims for this product. Some are printed on the bottle, others on the company website.

  • Suppresses hunger
  • Burns calories
  • Improves fat loss
  • Natural sleep aid
  • Promotes restful sleep
  • Makes it possible to fall asleep faster
  • Burns fat while you sleep
  • Enhances the mood
  • Provides relaxation
  • Enhances muscle building
  • Improves body composition
  • Prevents fat storage
  • Works with no jitters, headaches, or crashes

How Does Lean PM Night Time Fat Burner Work?

The main claim for this product appears to be it will help you to burn fat while you sleep.

Many of the other things the manufacturer is saying appear to be additional attempts to pull customers in.

Especially seeing that most of them don’t appear on the bottle.

Website pages are much easier to change than labels. Seriously, if this product helps with muscle-building and prevents fat storage, why wasn’t the label saying that from the start?

It’s pretty obvious what’s going on here.

Lean PM Night Time Fat Burner is a product for men and women who hope to sleep better and burn extra fat.

That’s what it’s been from the start.

The other claims appear to be only an attempt to make the product have a wider appeal in the hopes of boosting sales.

What’s the Best Way to Use Lean PM?

The standard dose is two capsules per day, taken on an empty stomach, 45 minutes before bed.

However, new users are advised to forget the standard dose and begin with only one capsule each night instead.

If no problems arise, it’s possible to start taking the full dose of two capsules per night from day three onward.

Pregnant mothers, nursing mothers, and people who have a medical condition or use medication are warned to get a doctor’s approval before beginning to use this nighttime fat burner.

Lean PM Night Time Fat Burner Ingredient Profile

Two capsules provide:

  • Vitamin B6   (10 mg)
  • Magnesium Citrate (150 mg)
  • Epigallocatechin gallate (EGCG) (300 mg)
  • L-Theanine (200 mg)
  • 5-HTP (150 mg)
  • Melatonin     (5 mg)
  • Bioperine     (5 mg)

Ingredient Potential

Vitamin B6

Manufacturers often add Vitamin B6 to energy drinks because it helps your body make the most of the energy it gets from food. Vitamin B6 also helps regulate the mood.

Magnesium Citrate

Magnesium citrate provides magnesium in a form that’s easy for your body to absorb.

Apart from being a mineral that’s necessary for good health, magnesium also regulates neurotransmitter activity. It’s hard to say why Jacked Factory is using it here and the company website fails to explain.

Epigallocatechin gallate (EGCG)

EGCG is the main antioxidant in green tea. As with other antioxidants, it helps you get rid of free radical toxins that could build up in your body and make you unwell.

Research suggests EGCG is the main fat-burning compound in green tea as well. (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6195899/)


This is an amino acid you can get by drinking green tea. Research shows it can help you to relax without making you feel drowsy.

Bearing in mind the fact Lean PM Night Time Fat Burner is a supplement you take before bed, it’s debatable if this is a good inclusion or not.


The 5-HTP stimulates serotonin production. The form you get in supplements often comes from the seeds of the plant Griffonia simplicifolia.

5-HTP is sometimes used as a treatment for depression, anxiety and/or poor sleep.

Serotonin is your body’s “feel-good hormone”. It improves your mood, may influence your appetite, and might even enhance sexual desire. The other thing it does is help you to sleep.

Although researchers know there is a relationship between serotonin and sleep, they have yet to prove taking it as a supplement can help with anything but depression.


Melatonin is a hormone manufactured in human pineal glands. It has the job of letting your body know when it is time to go to sleep and when to become awake.

The pineal gland produces extra melatonin as the day draws to a close. Your body responds to the increase by making you feel tired.

While you are sleeping, your melatonin levels decrease. This primes your body for the day ahead and encourages you to get up. 

Is melatonin a good ingredient? Some studies suggest consuming supplements that contain it may help you to sleep. Unfortunately, some studies suggest it does not.

The melatonin in supplements is often synthetic. However, some supplement manufacturers us melatonin taken animal pineal glands. Jacked Factory does not say which version it’s using.


Bioperine is a branded black pepper extract. The active component is piperine.

Piperine is put in many different kinds of supplement. Many diet pills have it. So do some bodybuilding supplements and pills that aim to improve your mind.

The ingredient is popular because its presence helps your body to absorb other ingredients more easily.

What Customers are Saying About Lean PM Night Time Fat Burner

It’s best not to trust any of the reviews on the manufacturer’s site. They are good but might be biased. The site exists to sell you Jacked Factory products, not to put you off.

The reviews you can read at Amazon are likely to be more reliable and many of them suggest the product is very good.

Unfortunately, there’s also a lot of customer reviews that say Lean PM Night Time Fat Burner did not provide any benefit at all.

On a more worrying note, some people say the product made them unwell.

Does Lean PM Cause Side Effects

Although many people seem to be able to use Lean PM Night Time Fat Burner without experiencing any side effects there are still plenty of people who do.

Believe it or not, some customers even claim using this product prevented them from sleeping and/or made them feel tired throughout the day.

Other reported side effects include:

  • Vision problems
  • Nocturnal panic attacks
  • Nausea and vomiting
  • Headaches
  • Stomach discomfort
  • Difficulty waking up in a morning
  • Carb cravings
  • Daytime fatigue

Obviously, there are issues with this product so you need to play it safe and give it a miss unless your doctor says it should be a good match for you.

Where to Buy Lean PM

If you live in the US or Canada, you have the choice of buying Lean PM Night Time Fat Burner from the Jacked Factory website and Amazon.com.

If you live elsewhere in the world, you won’t be able to buy this product at all due to the company’s limited shipping preferences.

Lean PM Cost?

Lean PM Night Time Fat Burner is pretty cheap. It only costs around USD 30 per bottle.

There are 60 capsules in each one so, if you are taking the normal dose, you’ll only need to buy one bottle each month.

However, you need to be aware you will need to pay the shipping costs on top. This is generally between USD 5 and USD 25, depending on which shipping option you choose.


Jacked Factory is offering a 90-day money-back guarantee. That’s pretty generous but the guarantee only applies to the first product you buy.

That means if you’ve purchased Jacked Factory products in the past you won’t be eligible for a refund if you find Lean PM Night Time Fat Burner is not for you.

Is Lean PM Worth Buying?

Lean PM Night Time Fat Burner contains EGCG. It’s a good fat-burning ingredient.

That means this formulation should be capable of helping you to lose more weight than you could if all you did was make the right dietary changes and get a little more exercise.

The formulation also has some melatonin. In theory, the ingredient may encourage you to sleep better.

In reality, it may not. It’s an ingredient that requires further study.

5-HTP may help with sleep too but, again, research is not wholly supportive of this ability.

The value of this product as a sleep enhancer is questionable.

Don’t buy it in the hopes it will provide a sure fix for your sleepless nights. Only buy it if you are willing to take a stab in the dark.

Bearing in mind all the reports of side effects, even if buying Lean PM Night Time Fat Burner seems like an acceptable gamble, please play it safe.

Don’t take it without getting the okay from a suitably-qualified medical professional first.
