Leptigen fat burner review

Overall score : 2.4

Overall, Leptigen is a good appetite suppressant and thermogenic fat burner. However, the ingredients used are NOTHING new or ground-breaking. Many products in the market offer the same ingredients, while the company behind Leptigen is relatively new and there is lack of credible user reviews online. Besides, Leptigen doesn't have "glucomannan", a very effective fiber ingredient that helps appetite suppression. So, in our opinion, there are better products out there. We recommend Instant Knockout , which has Glucomannan as well as all the ingredients that act as thermogenic metabolic boosters in Leptigen, and provides a better value for money. We also recommend Phen375, which is basically almost same as Leptigen BUT is from a reputed, well established supplement manufacturer and has been in the market since many years.

Review Topic: weight loss pills

“Fat burning pills” are among the most debatable products on the market, and for good reason: most are junk and some are downright dangerous, but not all are completely useless …

If you’re on the lookout for pills and powders to help you lose weight, we have good and bad news for you.

Let’s start with the bad:

No amount of weight loss pills and powders will likely make you lean.

If you’re seeking to lose fat, pill popping, even if taken excessively and aggressively is not going to be enough.

There just aren’t any secure, natural “fat burning” substances powerful enough to, all on their own, cause substantial weight reduction.

Now the good news:

If you know how to drive fat loss with proper dieting and exercise, certain supplements can accelerate the process.

About Leptigen

Leptigen is supposedly a nutritional supplement that again claims that it can help you experience safe, effective weight loss. How?

By having a proprietary blend of clinically researched ingredients that help your body release and burn stored fat, causing increased energy levels, boosted metabolism, and more calories burned. Thus, you can expect to really feel energized with more mental clarity.

All you need to do is take two capsules of Leptigen per day at least 30 minutes before meals, and its “highly effective” weight loss formula will start working.

“Yet another weight loss pill,” you’re thinking to yourself. “Lots of big claims and little real-world results.”

To be honest, Leptigen contains some powerful ingredients, and so does Phen375. But, both these products are only supposed to complement your overall weight loss program. They are not magic bullets.

If you ask us, we prefer Phen375 over Leptigen , based on its ingredients, user reviews and track record.

Both have similar weight loss ingredients, but Phen375 is in business since a longer time, has more diverse and effective ingredients and has a lot more positive reviews and happy customers over a longer period of time.

Are Leptigen’s Ingredients Effective?

Based on the label on Leptigen’s website, the supplement contains:

  • Green Tea Extract 200mg
  • Meratrim 400mg
  • Chromium 100mcg
  • Natural Caffeine USP 75mg

Let’s take a more in-depth look at each of these:


Created by InterHealth Nutraceuticals, Meratrim is a proprietary formula made of just two ingredients: garcinia mangostana (another name for garcinia cambogia) and sphaeranthus indicus.

Thanks to experts like Dr. Oz, people are sucking down garcinia cambogia pills as if it’s the next ephedra.

What is garcinia cambogia, though, and does it actually help you lose fat?

There’s absolutely no clinical proof showing that it (or sphaeranthus indicus) can provide any kind of weight loss benefits in humans. Rather, much of the existing research was conducted in a Petri dish or rats.

When it comes to Meratrim specifically, the Leptigen website references a 2013 study published in the Journal of Medicinal Food that found it, “in combination with a standard diet (2000 kcal/day) and moderate daily exercise, produces a clinically significant incremental reduction in body weight, waist, and hip circumference compared with diet management and exercise alone.”

In particular, individuals who took Meratrim managed to lose an average of 11 pounds, while the placebo group only lost about two pounds.

Although this definitely seems promising, it doesn’t appear that the manufacturer’s study has been peer evaluated, or that the results have been duplicated in subsequent studies.


Another InterHealth product, ChromeMate “is a niacin-bound chromium called chromium polynicotinate or chromium nicotinate that “may help increase the effectiveness of chromium, an essential trace mineral that may help support blood sugar levels already within normal range.”

Overall, chromium is a popular ingredient in most weight loss products, and often used to treat diabetes and improve weight loss results.

Also, there is some scientific proof showing that chromium may help improve weight loss results (the Leptigen website references this study from 1997), but by and large, it’s insufficient to concretely state that it works.

Green Tea Extract

Green tea is a common ingredient in herbal weight loss supplements, since it contains high Epigallocatechin gallate (EGCG) levels, a chemical that’s been widely studied.

Sorry to say, green tea hasn’t been clinically proven to provide any benefits, weight loss or otherwise. But, it may help boosting body’s metabolism over a period of time.

Caffeine and Fat Loss

Caffeine is present in lots of weight loss products, not just leptigen. Now, this is an interesting supplement.

Also, present in our favorite weight loss pills Instant Knockout and Phen375.

After all that doom and gloom I thought we’d start on a high note, which is how many people would describe caffeine.

What many people don’t know, however, is that caffeine does a lot more than give you an energy high.

Research shows that caffeine…

Caffeine accomplishes this last feat by increasing the amount of catecholamines in your blood, which are chemicals that mobilize fat stores to be burned. This, in turn, raises your body’s basal metabolic rate, which is the amount of energy it burns at rest.

The more energy your body burns every day, the more fat you can lose, and that’s why caffeine is an effective fat burner.

How to Use Caffeine to Lose Fat

The general dosage of caffeine seen in weight loss studies ranges between 2 and 6 mg per kg of body weight per day.

Personally, I take about 4 mg per kg of body weight per day when dieting for fat loss.

The only downside to caffeine as a weight loss aid is it loses its effectiveness over time as you become desensitized to it.

You can mitigate this by cycling your intake, however. Personally I go without caffeine 1 to 2 days per week when using it for fat loss purposes to maximize its weight loss effects.

Another way to make caffeine more effective is to co-ingest it with other natural substances that amplify its effects.

Problems with Leptigen

Sorry, guys! Leptigen is nowhere as effective as it’s hyped up to be.

The reason for this is simple: many of the “go-to” molecules found in products like Leptigen, like garcinia cambogia, raspberry ketones, and green coffee extract, are cheap, which is great for profit margins…but not very effective (if effective at all), which is not so great for your waistline.

One big benefit of taking the right fat loss supplements is they are particularly effective for reducing stubborn fat, which is usually belly fat for us guys and hip and thigh fat for girls.

So, as you can see, even the best “stack” of fat loss supplements isn’t game changing, but I think it’s worthwhile for both the lean looking to get really lean and overweight looking to get lean.

Synephrine and Fat Loss

Synephrine is a substance found in high amounts in the bitter orange plant, which has long been used in Traditional Chinese Medicine to treat various types of health disorders.

Chemically speaking, synephrine is similar to but less potent than the powerful weight loss compound ephedrine.

Synephrine helps you lose fat faster in several ways:

Synephrine’s weight loss benefits don’t stop there, either.

Research shows that pairing it with caffeine enhances both of the chemicals’ fat loss properties. Furthermore, synephrine is also a mild appetite suppressant because anything that increases the activity of adrenaline and noradrenaline can also reduce hunger.

The abundance of evidence is clear: synephrine is an effective fat loss aid. It’s a mild stimulant but is generally well tolerated and without side effects.

Synephrine is another one of the ingredients because of which I chose fat burner PHEN 375.

They’ve taken in a step further though and paired the synephrine with clinically effective dosages of two other molecules like Tongkat ali and more, providing some powerful weight loss effects in synergy.

How to Use Synephrine to Lose Fat

Clinically effective dosages of synephrine range from 25 to 50 milligrams and can be taken anywhere from one to three times daily, depending on individual tolerance.

The Bottom Line on Leptigen and Other Fat Burner Pills

Basically, weight loss pills are like most other supplements: if it sounds too good to be true, in all probability it is; and if you don’t really know what’s happening with your diet and training, they’re not going to help you.

They are not magic pills!

That said, if you need to pay your money sensibly and choose the “molecules” that are proven to speed up fat loss, you can lose pounds faster with the right products.

In our opinion, based on ingredients, overall Phen375 is a much better weight loss pill than Leptigen.

What Users Say on Synephrine?

Commercially, Synephrine is available as Phen375 which is produced by RDK global and have been turned into a big success in the weight loss supplement market.

Cayenne (Capsicum) – another secret ingredient to Phen375

Capsicum is an alkaloid, which is found in different kinds of pepper, being particularly extracted for manufacturing of Phen375 weight loss pills. Capsicum is the active substance, which helps to combat obesity.


prevents the growth of fatty cells;
lowers amount of fat in the blood;
encourages the activity of the respiratory tract;
is an anti-oxidant;
elevates microcirculation of the blood.

What’s more, Capsicum in Phen375 promotes the secretion of stomach, improving digestion.
