How Does Gluco20 Work?

Gluco20 is a combination of organic ingredients that are all scientifically tested and proven to attain and maintain healthy blood sugar levels.

The supplement focuses on improving beta cell count or functionality. Beta cells are found in the pancreas and are known to help the body produce and release insulin for a healthy blood sugar level.

According to the World Journal of Diabetes published by Yoshifumi Saisho, a diabetic person has a deficit of beta cells that enable the production of insulin. They may also have beta cells that do not work efficiently. The supplement contains ingredients that your beta cells need and may help them to improve their functionality[1].

Toxins and free radicals may also be responsible for the reduction of beta cells in the body. Gluco20 has ingredients rich in antioxidants which combat the effects of free radicals. In addition, Gluco20 also has magnesium as an ingredient, which helps regulate the functions of the existing beta cells. According to the Frontiers in Nutrition study published by Rongpeng Gong et al., Magnesium works to regulate the functions of the pancreatic beta cells[2].

Gluco20 Ingredients – Are they Safe?

In this section, we discuss more about the ingredients in this supplement and what benefits they carry.

Gymnema Sylvester Extract

This is one of the herbs used to make the Gluco20 supplement. It originates from India but can also be found in most parts of the world. It is known to suppress sugar cravings by making sweet foods unappealing to your taste buds. This is due to the gymnemic acid in the herb. According to the Nutrient study published by Sophie Turner et al., gymnemic acid blocks sweet taste receptors, making sweet foods unappealing. This eventually helps you lose weight and reduce high sugar consumption[3].

Vanadium Extract

Vanadium is a mineral mainly found in mushrooms, parsley, and shellfish, among others. According to the National Library of Medicine study published by S M Brichard et al., Vanadium mimics the functions of insulin. This makes vanadium a good mineral, especially for those suffering from low blood sugar[4].

Banaba Leaf Extract

Banaba originally grew in Asia, the Philippines, and India. The leaves have been used for many years as medicine. It helps the body use insulin more effectively, and it may also help reduce blood sugar levels. This ingredient has also been discussed in our GlucoSwitch blood sugar supplement, which has the same ingredients.

Banaba Leaf extract has a compound known as corosolic acid that helps to lower blood sugar levels. According to the BMC Complementary Medicine and Therapies Study, published by Tasnuva Sharmin et al., the Corosolic acid found in Banaba leaf extract acts as insulin and helps lower blood sugar levels[5].

Cinnamon Bark Powder

Cinnamon is a popular ingredient in many dietary supplements, and for good reason. It is also found in Blood Sugar Premier, another blood sugar supplement. Cinnamon bark powder is rich in antioxidants that help fight off free radicals.

A study in Nutrients published by Maria Leonor Silva et al. confirmed that cinnamon bark powder extract imitates the effects of insulin and, therefore, helps lower blood sugar levels[6].

Other ingredients include Alpha Lipoic acid, licorice root extract, and L-taurine, all in their organic form.

Verdict: We approve of the key ingredients in this product because they are not only organic but they are also scientifically proven to work.

We Tried Gluco20– Our Take

“I had numbness, lack of energy, and severe headaches for quite some time, and the doctor confirmed that I was prediabetic. I began some medication, but I still experienced the symptoms. I found Gluco20 online, and upon asking, my doctor said I should try it along with my medications.

I began noticing some changes after a week of taking the supplement. The numbness and the headache disappeared within a week, and after a month, the prediabetic symptoms were gone. I will still need more tests to affirm that I'm medically okay. I would, however, recommend the Gluco20 to anyone suffering from unhealthy blood sugar levels.”

Benefits of Gluco20

Here are some key benefits of using Gluco20;

Helps maintain healthy blood sugar levels

Gluco20's key ingredients, like chromium and cinnamon extracts, can assist in keeping blood sugar levels already in the normal range. In addition, this eventually helps maintain a healthy glucose metabolism.

Supports healthy insulin function

Components like bitter melon, vanadium, and vitamin D may aid the body's insulin production and help it utilize insulin more efficiently. Magnesium also helps the existing B-cells to produce insulin in the body. Proper insulin function is key for a balanced blood sugar level.

Provides antioxidant support

The supplement also contains ingredients such as alpha lipoic acid (ALA) containing antioxidants. These compounds are known to help neutralize cell damage from oxidative stress and high blood sugar.

Boosts energy levels

Gluco20 not only helps you achieve healthy blood sugar levels but also enhances your overall body energy. By assisting proper carbohydrate metabolism and cell energy production, Gluco20 helps to increase daily energy, preventing crashes from blood sugar spikes. This allows you to stay energized and stay productive throughout the day.

Supports healthy body weight

Massive body weight may be a cause of blood sugar spikes and other prediabetic and diabetic symptoms. Regulating insulin and glucose response supports proper hunger signals and fat burning. This makes maintaining healthy body weight and composition easier for some individuals.

Bruce Hartman said this.

First, I am not a huge fan of reviews, and I rarely write one. I feel strongly enough about the value and effectiveness of Gluco20 that I am taking the time to tell you about it. I was turned on to the product by the owner of the company, and I decided to purchase this product to test it against some of the other wide supplements my doctor has recommended. I took it for a few weeks, along with my diabetes meds. I noticed it started working very quickly, and soon thereafter, my readings were so much better! I have completely stopped taking my prescription medications, which has saved me hundreds of dollars. I am sleeping better, I lost weight, I am eating food I haven't eaten in years. My doctor asked me what I have been doing for such drastic results, so I sent him the link to this product so he can recommend it to his other patients.

Here is a review from Noelynn Alcaraz
