GlucoBerry Reviews – Does It Work GlucoBerry ?

GlucoBerry is a nutritional supplement sold exclusively online, marketed to diabetics and anyone with blood sugar problems; the supplement can purportedly activate a “blood sugar drain” within your kidneys to flush unnecessary sugar away from your body.

Keep reading to discover everything you need to know about GlucoBerry and whether or not it lives up to the hype today in our review.

What is GlucoBerry?

GlucoBerry is a blood sugar support supplement designed to help drain blood sugar away from your kidneys.

By taking two capsules of GlucoBerry daily, diabetics and others with blood sugar control issues can purportedly maintain healthy blood sugar.

GlucoBerry is made by a company named MD Process. The company manufactures GlucoBerry in the United States in an FDA-registered, GMP-certified facility. The supplement was formulated by Dr. Mark Weis.

Only available on the official website, each bottle of GlucoBerry is priced at $59.

GlucoBerry Benefits

According to, GlucoBerry has helped thousands of men and women enjoy benefits like:

  • Have the freedom to enjoy your favorite desserts again, even sugary desserts

  • Reduce blood sugar spikes

  • Avoid feeling ashamed or embarrassed when checking blood sugar at the doctor

  • Support independence and confidence by knowing their family doesn’t need to worry about them

  • Stay in control of your own health in your own way

According to customer reviews on the official website, GlucoBerry has helped people feel more energetic and vibrant. One customer’s doctor described her numbers as “great” after taking GlucoBerry, for example, and another customer claims her blood sugar “is under control” thanks to GlucoBerry.

Who Created GlucoBerry?

GlucoBerry was formulated by a physician named Dr. Mark Weis, who works for the nutritional supplement company MD/Process.

Dr. Weis is an award-winning physician, medical consultant, and author. He’s also board-certified by the American Board of Ambulatory Medicine. He spent years of his career serving America’s military and veterans as a civilian physician with the Wounded Warrior Clinic at Fort Knox.

Dr. Weis stumbled upon Harvard research describing a “promising new therapy” for lowering blood sugar, and he decided to formulate a supplement based on that discovery. Using his professional medical experience and training, Dr. Weis aimed to create the ultimate blood sugar support supplement.

How Does GlucoBerry Work?

All diabetes supplements claim to support blood sugar. However, not all of them work as advertised. GlucoBerry claims to work differently than other diabetes supplements because it focuses on areas outside of insulin.

According to the official GlucoBerry website, most diabetes treatment focuses on:

  • Supporting your pancreas to continue proper production of insulin

  • Supporting insulin sensitivity and avoiding insulin resistance

Instead of focusing on either of these two effects, however, GlucoBerry takes a different approach. The manufacturer believes insulin is “not a magic target for an all-powerful blood sugar aid.” Instead, it’s just one part of your body’s blood sugar regulation system.

Here’s how Dr. Weis describes it on the official website:

“Insulin is a bit like a taxi driver. It helps transport sugar to different places in your body. But it can’t maintain balanced blood sugar on its own.”

Insulin simply moves sugar around from one place to another. It transports sugar to your muscles and cells as needed, for example.

And, when your muscles and cells don’t need sugar, insulin transports excess sugar to the kidneys. When your kidneys are functioning properly, they transfer excess sugar to your urine, then flush it out of your body.

Insulin can take sugar to your kidneys. However, insulin cannot actually flush sugar out of your body. Even if you optimize insulin levels, your body may not be eliminating blood sugar from your body, leading to high blood sugar levels over time.

That’s why GlucoBerry takes a different approach by targeting the blood sugar drain in your kidneys.

GlucoBerry Targets the Blood Sugar Drain to Flush Unneeded Sugar

GlucoBerry works by targeting something called the blood sugar drain. According to Dr. Weis, the blood sugar drain is “the main exit point” for flushing unnecessary sugar out of your body.

When your blood sugar drain is working properly, it takes excess blood sugar from your kidney and passes it out of your body as urine, helping to balance your blood sugar.

By supporting your blood sugar drain, you can purportedly eat your favorite foods without worrying about spikes. Any excess sugar is carried to your kidneys, then drained via the blood sugar drain.

Over time, however, your blood sugar drain may not function correctly. Age, poor diet, and lifestyle habits can all impact the function of your blood sugar drain, making it harder to maintain healthy blood sugar levels as you age.

Age Reduces Blood Sugar Drain Function

As you get older, your blood sugar drain functions worse and worse. For example, people in their 20s tend to have 20% lower fasting blood glucose levels than people in their 40s.

As you reach your 40s, 50s, 60s, and older, your blood sugar drain stops working as effectively as it used to. Even if you’re eating a normal diet and following safe lifestyle factors, you might struggle to maintain normal blood sugar levels because of your blood sugar drain.

Dr. Weis cites research from Johns Hopkins University proving the effect of age on blood sugar drains. Researchers at Johns Hopkins performed autopsies on the kidneys of adults of different ages. They found kidney samples from older adults had worse blood sugar drain function than kidney samples of younger adults.

Specifically, the kidneys of older adults are covered in “sticky gray mucus.” This mucus is made of a specific protein called SG2, and GlucoBerry is designed to work by targeting SG2.

GlucoBerry Targets SG2 Protein to Support Healthy Blood Sugar

As you get older, your blood sugar drain function becomes worse. However, GlucoBerry can support blood sugar drain.

Sodium-glucose cotransport 2, or SG2, is a type of “sticky protein” that forms the “sticky gray mucus” over the kidneys of older adults. As SG2 collects in and around your kidneys, it impedes their ability to lower blood sugar.

Here’s how Dr. Weis explains the effects of SG2 on blood sugar:

“When unneeded blood sugar takes its taxi cab ride on your insulin, and your insulin delivers it to your kidneys…It’s this Sticky Gray Mucus that determines how much of that sugar is flushed away, and how much your bloodstream still needs.”

In other words, the SG2-based sticky gray mucus determines how well your blood sugar drain works.

Some people have naturally higher levels of SG2 than others – regardless of lifestyle habits. Due to genetics and certain other factors, some people produce more SG2 protein than others, which could lead to blood sugar drain issues.

With that in mind, GlucoBerry aims to optimize SG2 levels using a specific blend of natural ingredients – including the maqui berry.

How the Maqui Berry Works to Support Healthy Blood Sugar

Dr. Weis looked for natural ways to support SG2 protection and kidney health with age, and he stumbled upon the maqui berry.

Here are some of the reasons Dr. Weis chose the maqui berry for GlucoBerry:

Maqui berry is a small, purple berry found in some South American wines native to Chile; the maqui berry tree is now grown in the United States, Europe, and Australia. Maqui berry is rich in an antioxidant called delphinidin.

Research shows delphinidin can have significant effects on blood sugar.

Specifically, researchers found delphinidin supports a healthy blood sugar drain by telling your body to make the proper amount of SG2 protein, thereby supporting healthy blood sugar

In one study, researchers gave maqui berries to 20 men and women. Participants took either 200mg of maqui berry with delphinidin or a placebo. Then, participants ate rice to check for blood sugar level spikes. 60 minutes after eating rice, the control group raised their blood sugar by 24%, which is considered normal. However, the maqui berry group “saw barely any spike” after 60 minutes. And the maqui berry group had 15% lower blood sugar levels.

In a separate study, researchers repeated the test with 1/4 cup of pure glucose. Typically, pure glucose is only used for trials measuring the effects of blood sugar. It’s pure sugar, and it will lead to an immediate blood sugar spike in anyone who eats it. In the study, researchers found people taking maqui berry before taking sugar had their blood sugar levels spike 15.1% less.

In another study, researchers tested the long-term effects of maqui berry by asking participants to take 180mg of maqui berry extract every morning for 3 months. Researchers found participants’ blood sugar drains were functioning 23% better compared to a placebo.

According to MD Process, however, maqui berry is difficult to find. You can’t buy maqui berry at a standard supermarket. Fortunately, MD Process discovered a source of maqui berry that is premium and purified, helping ordinary people support blood sugar at a reasonable price. It’s called Delphinol, and it’s a proprietary maqui berry-based formula.

GlucoBerry Ingredients

GlucoBerry contains a special type of maqui berry extract called Delphinol. That formula is particularly rich with delphinidin, the active ingredient within maqui berry to support healthy blood sugar.

Here are all of the ingredients in GlucoBerry and how they work, according to the official website:


GlucoBerry contains Delphinol, a trademarked formula made from pure maqui berry. The formula is specifically designed to be rich with delphinidin, the active ingredient in maqui berry linked to the blood sugar lowering effects. Maqui berry is also rich in antioxidants to support weight loss, inflammation, and healthy blood sugar in other ways.


Many experts recommend diabetics take chromium to help balance blood sugar. Chromium is a crucial mineral for anyone. However, diabetics seem to have particularly low levels of chromium, and these low levels can contribute to poor blood sugar management. According to the official GlucoBerry website, chromium complements biotin to maintain healthy blood sugar levels.


Biotin is a B-vitamin linked to healthy blood sugar and insulin levels. Each serving of GlucoBerry contains the same dosage of chromium and biotin used in a major Yale University study. There are 600mcg of chromium and 2mg of biotin in each serving of GlucoBerry.

Gymnema Leaf:

Found in many diabetes formulas and blood sugar supplements, GlucoBerry contains Gymnema leaf to support healthy blood sugar. It’s a tropical herb used for centuries in traditional medicine. Today, we know Gymnema leaf seems to work in different ways to support blood sugar.

Together, these four unique ingredients can support blood sugar significantly.

What to Expect When Taking GlucoBerry

You can buy a 1-month, 3-month, or 6-month package of GlucoBerry. Depending on which package you select, you could experience different effects.

Here’s what to expect when taking GlucoBerry, according to the official website:

People taking a 1-month supply of GlucoBerry can expect to start “just getting on the path of maintaining healthy blood sugar,” according to the official website. People with diabetes tend to have higher than normal blood sugar levels, but GlucoBerry can purportedly help maintain healthy blood sugar.

People taking a 3-month supply of GlucoBerry can continue “eating their favorite foods” while boosting energy all day.

People taking a 6-month supply of GlucoBerry are more serious about managing their blood sugar and fortifying their health. They want to keep their blood sugar healthy and avoid the long-term health risks of imbalanced sugar levels.

Overall, the makers of GlucoBerry seem confident in the ability of their formula to balance and support healthy blood sugar. They also claim that “the longer you use GlucoBerry, the better the results.”

Scientific Evidence for GlucoBerry

GlucoBerry is a doctor-formulated supplement, and MD Process cites over a dozen studies to validate the claims made on the GlucoBerry website. We’ll review some of that scientific evidence below to determine if GlucoBerry really works as advertised to support blood sugar.

In this 2015 study published in the Journal of Medicinal Food, researchers found maqui berry inhibited inflammation throughout the body. Researchers tested the effects of maqui berry on macrophages compared to blueberry and found maqui berry had significant anti-inflammatory effects.

A separate study broke down the pharmacological effects of maqui berry, finding that maqui berry was rich with anthocyanins and other flavonoids linked to blood sugar effects and inflammation, along with alkaloids, cinnamic acid, benzoic acid derivatives, and other compounds.

Meanwhile, Gymnema Sylvestre has been linked to benefits in type 2 diabetics. In this 2010 study published by MD Process, for example, researchers found Gymnema Sylvestre reduced fasting blood glucose in various ways while also leading to a favorable shift in lipid profiles.

There’s a reason many diabetes supplements contain a combination of chromium and biotin – and for good reason. In this 2006 study, researchers found that the combination of chromium and biotin significantly impacted blood sugar control in patients with type 2 diabetes. In a double-blind, randomized, controlled trial, researchers found taking 600mcg of chromium and 2mg of biotin per day led to significant blood sugar control over a 4-week period compared to a placebo.

Chromium can also work on its own. In this 2013 study, researchers found chromium alleviated insulin resistance in type 2 diabetes.

GlucoBerry contains a specific maqui berry formula named Delphinol, a standardized maqui berry formula rich in delphinidins. That formula has completed specific clinical trials verifying it works as advertised. In this 2014 study, researchers found that Delphinol lowered blood glucose and insulin after a meal compared to a placebo.

Overall, GlucoBerry is a doctor-formulated supplement with a blend of science-backed ingredients to support blood sugar in diabetics.
