Lean Gene Reviews: Ingredients That Work as Effective as Advertised?

Lean Gene is a weight loss supplement that works off on the principle that a specific gene controls weight loss and how taking the science-backed LeanGene formula can reactivate the resting metabolism to experience weight loss without giving up our favorite foods.

Losing weight is hard especially if you don’t know where to start. There are of course several “online gurus” who can help you lose weight with diets and other similar methods. But what people don’t know is that dieting and other similar methods can adversely affect your health.

With dieting techniques aside, supplements are the best options, and Lean Gene is the best one out there. This weight loss supplement basically works by targeting the UPC2 gene to boost your resting metabolism, this way you can lose weight efficiently.

Lean Gene – What Is It?

As you already know, Lean Gene is a weight loss supplement that consists of only 100% natural ingredients geared towards revitalizing a slow metabolism. In addition, this weight loss supplement works in an entirely different manner compared to other weight loss supplements. This supplement is known for its ability to target specific hormones in the body and help them improve your resting metabolism, resulting in effective weight loss.

Lean Gene was created by a researcher and nutritionist named Janet Hadvill, and as mentioned earlier, this supplement targets the UPC2 gene to help you burn more fat while in a resting state.

This is truly a one-of-a-kind supplement as it is the very first of its kind; there is no other supplement that targets genes and hormones to help you boost your resting heart rate. Unlike most supplements that help you lose weight with the help of stimulants and other natural herbs, Lean Gene basically alters your genetic data to help you boost fat-burning abilities.

Lean Gene – How Does This Supplement Work?

The ingredients used in this supplement make all the difference in the world.

Here are the ingredients used in the making of Lean Gene:

  • Choline
  • Yerba Mate
  • Green Tea
  • Cinnamon Bark Extract
  • Resveratrol
  • Betaine

All of the above-mentioned ingredients are a part of a unique blend that helps you lose weight by increasing your resting rate of metabolism, and this is achieved by targeting the UPC2 genes in your body.

Everyone should know about weight loss, and that metabolism plays a huge role. People with higher metabolism rates always tend to lose more weight, and they are able to do it easily compared to individuals with lower rates of metabolism.

But with the help of this weight loss supplement, Lean Gene, your body’s metabolism will receive a good boost, which will help you efficiently lose weight.

How Does Lean Gene Work With UPC2 Gene To Improve Metabolism?

As per their official website, Lean Gene is the only one on the market that aims to target the UPC 2 genes to help you lose weight, and the UPC2 is also referred to as the “fat-burning gene.”

Studies show that by targeting the UPC2 gene, the rate of your body’s resting metabolism increases, and by doing so, you will be able to shed fat without any problems. UPC2 is regarded as the fat-burning gene since it produces a protein involving your body’s metabolic rate and fat breakdown:

  • Lean Gene is said to increase the amount of the UPC2 gene in your body. The organization claims to be able to enhance gene levels within your body, making it easier to burn large fat without exerting much strain.
  • Here is the process that this supplement uses to help you shed fat; keep in mind that this is a 3-step procedure:
  • It aims and targets the UPC2 genes in your body, this way, your body’s fat-burning abilities are increased.
  • Lean Gene further works on improving your resting metabolic rate. Once your resting metabolic rate increases, your body will be able to shed fat when you’re resting.

In addition to this, Lean Gene also helps in the prevention of future fat stores. This way, you can eat what you want and not gain too much weight.

Furthermore, the manufacturers of this Lean Gene also state that, when you start using this supplement, individuals can see results after 72 hours of using Lean Gene, which is quite amazing as many supplements on the market do not offer.

Lean Gene – What Are Its Benefits?

As you may have guessed, this supplement has quite a lot of health benefits. Without further ado, here’s a small list of the benefits that Lean Gene has to offer:

  • It acts as an appetite suppressant and helps in the reduction of cravings and hunger
  • Has the ability to increase fat burning abilities of your body
  • It also is known to help maintain good levels of blood sugar
  • It significantly boosts your resting metabolism
  • It is the only supplement that targets your UPC2 gene
  • It is one hundred percent natural
  • It helps you burn stored fat easily.

Lean Gene – More About The Creator

As you read in the earlier paragraphs, Lean Gene was formulated and created by Janet Hadvill. She is a certified nutritionist and has been for the past 18 years. She is also referred to as the “gene girl” mainly because she is academically certified in gene therapy, genomics, and epigenetics.

Janet, unlike her sister, wasn’t as physically fit as her twin sister, and over the course of time, she struggled with weight loss; one day, when she was traveling through the landscapes of Brazil, she happened to chance upon a scientific breakthrough so big that it would change her life completely.

According to her, the locals used a drink known as “Brazilian water,” This was a drink mixed with a variety of natural plants and herbs; this specific blend helps improve weight loss and targets your UPC2 gene.

Lean Gene – What Are The Ingredients Used?

Lean Green is made up of only natural ingredients and with no synthetic ingredients or chemicals used in the making of this supplement.

Here are the ingredients used to make this supplement:


This is an ingredient known to improve metabolism and is also known for its fat breakdown capabilities. Moreover, this supplement can also help you with the regulation of healthy blood sugar and can increase insulin resistance.

Yerba Mate

Yerba mate is a South American herb that has been used in ancient medicine for generations. Janet claims that the yerba mate in Lean Gene stimulates the UPC2 gene and modifies its activity, letting you lose more weight by raising your body’s metabolism. Janet further says that the substance operates without diets or exercise, rendering weight loss simple. Yerba mate, according to a study using animals, found yerba mate could reduce appetite and boost metabolism, which can help with weight loss. It also decreased the total number of fat cells and reduces the amount of fat they hold.


Choline is a source of methyl groups that are needed for the many steps in metabolism. It is commonly present in nootropic supplements for its central nervous system benefits and is said to help disperse stored fat and improve memory when combined with inositol.


This ingredient has been known to act as an appetite suppressant. Furthermore, this ingredient helps in shifting and re-distributing body fat.

Cinnamon Bark Extract

This ingredient is among the most used natural medicinal plants. This ingredient is known for its ability to help regulate blood sugar levels and maintain optimal insulin levels. It helps in boosting metabolism and makes it easier for people to lose weight by increasing the breakdown of fat in the body.


There are two types of resveratrol used in this supplement. One is a powdered version of resveratrol, and the other is extracted from grape seeds. Resveratrol is known for its powerful and high number of antioxidant properties.


Polyphenols are found in Lean Gene thanks to two organic ingredients: grape seed extract and green tea. Green tea extract is high in polyphenols such as ECG, which are associated with fat loss, whereas grape seed extract is high in polyphenols like resveratrol, which promote inflammation across the body. These nutrients help in the reduction of body fat by stimulating fat decomposition, controlling hunger, and even influencing the activity of fat and unhealthy genes.


This is a fatty acid when the dietary fibers in your gut decompose. Butyrate is released during the decomposition process. This ingredient is known to help boost metabolism significantly; apart from that, it also helps in the maintenance of a healthy digestive system. It does that by acting as a probiotic bacteria.


This is one of the most powerful natural extracts you can get your hands on. Good levels of chromium in your body can help people with diabetes or blood sugar problems.
