Mara Labs As Seen On
Who made it
Built by a scientist and a physician together
The scientist behind the formula
John Gildea, PhD
Co-founder, Mara Labs
GLPerfect was formulated by Mara Labs co-founders John Gildea, PhD and Martin Katz, MD, and is made under one roof in Charlottesville, Virginia.
The problem
Great Ingredients Only Help If They Get In
Berberine and EGCG, the key compound in green tea, are two of the most studied plant compounds for daily metabolic support.
But there is a catch that most labels do not mention.
Both are hard for the body to absorb.
Much of what you swallow never makes it through the gut barrier, so most supplements answer with bigger and bigger doses. GLPerfect takes a different path: it helps more of these compounds get through, so a smaller dose can do more.
Plant Protein + Sea Carbohydrate
Our patent-pending technology binds a plant-based protein (hemp) to a sea-based carbohydrate (alginate).
That creates the BerbElite® and Green Tea Extract complexes inside every GLPerfect capsule, designed to support absorption through the gut barrier.
How GLPerfect is different
Most formulas add more powder.
More of the same compound, down the same crowded path.
GLPerfect works on the absorption step.
Berberine and EGCG ride on our carrier complexes to help them pass the gut barrier.
Three ingredients, one simple routine.
Berberine, EGCG and alpha lipoic acid together, two capsules a day with meals.
GLPerfect has not been compared to other berberine or green tea supplements in head-to-head clinical trials. This section describes formula design and mechanism.

Questions About GLPerfect
What is GLPerfect?
GLPerfect is a dietary supplement from Mara Labs. It combines bioavailable berberine HCl and EGCG from organic green tea extract, each bound to our patent-pending carrier, with alpha lipoic acid.
What are the benefits of GLPerfect?
GLPerfect helps curb sugar cravings and supports a healthy metabolism and daily energy.
What is in your novel organic carrier molecule?
Our patent-pending technology binds a plant-based protein (hemp) to a sea-based carbohydrate (alginate). This creates the BerbElite® and Green Tea Extract complexes that allow for superior absorption through the gut barrier and, therefore, great effectiveness.
What makes GLPerfect different from other berberine supplements?
The fat-soluble molecules in GLPerfect, berberine and EGCG (from green tea extract), pass through the gut barrier in amounts that make a difference in one’s biology and, therefore, increase their beneficial effects.
How do I take it, and how long does a bottle last?
We recommend two capsules per day: one with your first meal and one with your last meal. Each bottle has 60 capsules, a 30-day supply.
Can I stop taking BerbElite if I start taking GLPerfect?
Both BerbElite® and GLPerfect have bioavailable berberine HCl as ingredients. The difference is that BerbElite has BrocElite sulforaphane in it. If you are not taking BrocElite, we recommend staying on BerbElite. If you are taking BrocElite, you do not need to take both BerbElite and GLPerfect.
Is your green tea extract organic?
Yes.
Where is GLPerfect made?
GLPerfect is manufactured in Charlottesville, Virginia. Our capsules come from Canada and Colombia, and our powders are sourced from all around the world. All of our ingredients go through a rigorous selection process and are only ever sourced from transparent and non-GMO sources that are GMP certified and tested for contaminants like glyphosate, pesticides, and heavy metals.
Who can take GLPerfect?
GLPerfect is intended for adults. If you are pregnant or nursing, have a medical condition, or take prescription medications, please consult your healthcare provider before use. Some medications may interact with berberine.
Are there any side effects?
GLPerfect is generally well tolerated. As with any supplement, individual responses vary. Take it with meals and a glass of water, and check with your healthcare provider if you have questions or concerns.
How does the subscription work?
If you choose to subscribe, your order ships on the schedule shown and renews automatically at the price shown until you cancel. You can skip, change or cancel anytime from your account.
Is there a guarantee?
