What Is Leptigen®?

What Is Leptigen®?

This natural weight loss supplement is made in the USA and has zero artificial fillers, binders, or ingredients. Leptigen® prides itself on using the best ingredients possible. Each component in this diet supplement pill was designed to work together to give you maximum results.

The key, active ingredients are backed by published clinical research, so you know you’re getting a high-quality product.

The manufacturers of Leptigen® claim their unique recipe can increase weight loss up to four times faster than diet and exercise alone.

Leptigen® doesn’t rely on one way to help you shed those unwanted pounds.

Leptigen® acts as an appetite suppressant, and a metabolism booster, and adds ingredients that help the absorption rate so you can take your weight into your own hands.

If you are serious about losing weight and want to try something with ingredients you can pronounce, Leptigen® might be your best bet.

Effective Ingredients in Leptigen®

Effective Ingredients in Leptigen®

Leptigen® is a proprietary weight-loss blend made of fairly high-quality components.

Active Ingredients


Green Tea Extract


What’s so special about this combination?

Unlike a lot of weight loss supplements that we review, all the ingredients in Leptigen have been shown in scientific studies to aid in weight loss.

Let’s take a look at the individual ingredients.


If you haven’t heard of Meratrim® before, you’re not alone. It’s a branded portion of the proprietary blend and not widely available to the public. However, Meratrim is the biggest driving component to weight loss in the Letpigen® formula.

Meratrim® combines two main ingredients (Sphaeranthus Indicus and Garcinia Mangostana) that work together. Both are clinically proven to aid in weight loss.

Garcinia Mangostana, also known as Mangosteen, can also help reduce inflammation and calm your skin, making you appear younger.

The tannins in Mangosteen have also been known to help with digestive issues that can cause bloating.

Mangosteen’s primary purpose in this formula, however, is to increase the absorption rate of Sphaeranthus Indicus into your body.

Sphaeranthus indicus works by stimulating your metabolic functions and helps you burn fat at a faster rate. Anecdotal evidence suggests that Sphaeranthus Indicus can also assist in keeping weight loss at bay.

To learn more about the main active ingredient in Leptigen take a look at this quick YouTube video. It will explain in depth how Meratrim will work to help you burn fat and keep it off throughout your diet.

Green Tea Extract

Once the leaves, buds, and stems are hot brewed, Greet Tea Extract provides molecules called polyphenols which are responsible for most of the benefits of Green Tea.

The polyphenols in conjunction with other antioxidants also present in Green Tea Extract prevent inflammation and assist in weight loss.

Not only can Green Tea help increase your metabolism but it also aids in appetite suppression.

Green tea extract works to increase fat oxidation and may also increase postprandial thermogenesis, both of which can aid in the overall goal of shedding fat.

According to this study, men who exercised and took green tea extract burned 17% more fat than those who exercised without supplementation.


Leptigen® also includes a moderate amount of caffeine in its blend, which is included to stimulate the metabolism of fatty acids.

There are a couple of ways in which caffeine may aid weight loss.

First, caffeine is thought to work as an appetite suppressant which can limit caloric intake over the course of time.

Caffeine may also stimulate thermogenesis, which is how the body generates energy and heat through food digestion.

Reviews: What Are People Saying?

Reviews: What Are People Saying?

Leptigen® has been getting hit-or-miss reviews. Some people are absolutely in love with it as a kick-starter for their diet, while others didn’t see any weight loss–except to their wallet.

Let’s take a look at some of the reviews around the web. These reports reflect an average feeling from new users and long-time users.

‘This is an amazing product. It suppresses my hunger. When I don’t take it, I can tell a big difference. The weight loss is slow…but steady. I don’t work out…if I did…it would probably be even more weight loss. I just purchased my 3rd bottle and am very happy with it.’ Amazon

‘I ordered some Leptigen when it was first released and actually got another tub from because I’ve been so happy with it. I’ve been waiting another 2 or so weeks before I plan to post my results and successes. I can say this, though, it has made a very noticeable difference to my dieting. Helped me get under 7% body fat for the first time in my life.’ BodyBuilding.com

‘Meh, didn’t really work for me. A dietitian recommended it from first-hand experience, and I can see how it could potentially work (definitely felt it curbed my appetite and regulated my digestion), but it didn’t do much for me personally.’ Amazon

Taking Leptigen®

Taking Leptigen®

Take 1-2 capsules, depending on weight and gender, twice daily.

If possible, take the capsules before meals with an 8-ounce glass of water for optimal absorption. Tablets should be taken anywhere from half an hour to two hours before mealtimes.

When using supplements that stimulate your body, you should take care not to combine them with other stimulating drugs.

One serving (2 capsules) of Leptigen, for instance, has the same amount of caffeine as one cup of coffee.

Consuming coffee, tea, or soda on top of this supplement can leave you feeling jittery and anxious, especially if you’re sensitive to caffeine.

It’s also not recommended to take Leptigen® 4 hours before bedtime. Otherwise, you may find yourself having a restless night’s sleep.

It is always advised to consult your doctor before introducing any dietary supplement into your daily routine especially if you are pregnant or nursing.

Published Studies on Leptigen® and Its Ingredients

Leptigen® has some big claims.

Are they valid?

Three separate published clinical studies can help you determine if Leptigen’s claims are as accurate as they say.

Below, you’ll find the final conclusions of a few trials that were done on active ingredients in Leptigen®.

A Study on the Key Ingredients

In this first double-blind clinical study, two of the main ingredients of Leptigen® were paired together to determine the effectiveness of weight management.

Sphaeranthus indicus and Garcinia mangostana capsules were given to half the subjects and placebo to the other half.

After only five days the subjects taking the herbal supplement were identified as having reduced weight as well as decreased hip and waist circumference.

The final findings indicated that this supplement could be helpful for weight management.

The Relationship Between Caffeine and Weight Loss

The Relationship Between Caffeine and Weight Loss

The second study was done on the correlation between caffeine and weight loss. Obesity is caused by an imbalance of energy intake (EI) and expenditure (EE).

For weight loss to be increased, it was found to either be necessary to increase the expenditure or decrease intake.

Caffeine was determined to do both. It increases energy expenditure helping to regulate body fat.

It was also determined that caffeine can be used to decrease energy intake with its effects on appetite. Therefore, it was deemed by medical professionals as a possible body weight regulator.

However, it was also noted that caffeine in too large of doses could cause some adverse side effects such as anxiety and increased heart rate. Caffeine should be used in moderation in supplements.

Can Green Tea Extract Keep Off Weight?

Can Green Tea Extract Keep Off Weight?

The final study was done as a randomized placebo-controlled study. Its primary focus was to determine if Green Tea Extract was able to allow dieters to keep weight off, once lost.

While the women who did receive the GT extract held off more weight, the numbers are not significant enough to make a final call.

Although it was determined that Green Tea has the potential to help maintain energy expenditure, there was little evidence to show that it kept weight off over a 3-month lifestyle intervention.

More research needs to be done before it can be confirmed that GT would be beneficial for the maintenance of weight after the initial loss.

A Closer Look at Leptigen®

Based on the findings from these three published clinical studies, the claims that Leptigen makes about its product don’t seem too far off.

All the key components of the proprietary blend are legitimately good for kick-starting your weight loss routine.

However, it’s not ever as easy as it appears. Diet and exercise are still necessary if you plan to keep the unwanted pounds at bay.

Critical Remarks

While most of the ingredients in this dietary supplement are 100% safe to use, even long-term, it’s still important to listen to your body.

Introducing new ingredients into your system may cause reactions that are unwanted.

The main side effect you will likely notice is digestive problems as your body becomes adjusted to your new diet and supplementation.

Some were unable to continue past the initial period, and others stated that the uneasiness cleared itself up within 2-3 days.

If you have a sensitive stomach or have digestive issues, you may want to start yourself on a half dosage until your body becomes adjusted to the supplement.

Adverse Effects of Caffeine

Leptigen® contains high doses of caffeine. You should be aware of your tolerance before taking this supplement. Start off slow and work your way up to the desired level.

Remember never to exceed the manufacturer’s recommended dosages.

If you notice any of the following symptoms, you may be ingesting too much caffeine into your system.

  • Restlessness
  • Irritability
  • Nausea
  • Rapid heart rate
  • Trouble breathing
  • Dizziness
  • Diarrhea

If you’re still unsure if Leptigen® is right for you, you might want to consult your doctor before use. Together you should be able to come up with a weight loss plan that’s suitable to your lifestyle.
