"As a co-founder at Mara Labs, I'm excited about the GLPerfect formulation because it evens the scales in matching one’s effort with something that supports your weight goals.
After taking two capsules, I noticed a steady drop in my blood sugar levels and felt more balanced overall. It really seems to support healthy metabolism and energy.*”
- John Gildea, PhD, co-founder at Mara Labs**
"Some weight loss drugs out there are dangerous and can shutdown the gut function and motility. I like the idea of a supplement that provide GLP-1 support naturally."
- Martin Katz, MD, co-founder at Mara Labs**
Berberine is a plant-based compound traditionally used in Ayurvedic and Chinese medicine — now studied for its powerful metabolic effects.
GLPerfect uses a refined form of berberine at a strong, science-backed dose. It’s paired with a patent-pending organic carrier molecule designed to support absorption.
Our berberine may help:
- Turn on AMPK, your body’s natural fat-burning switch
- Use fat for energy, not store it
- Support healthy blood sugar and insulin, which helps with weight and cravings
- Promote good gut bacteria, linked to weight and inflammation
- Release GLP-1, a hormone that helps you feel full longer*
*Based on animal and cell studies. More research is needed to confirm this effect in humans.
Your Metabolism Isn’t Broken — It’s Just Misfiring
Over 40 and feeling “fluffy”? Maybe you feel like your body changed overnight.
What used to work for weight loss doesn’t anymore. You’ve been feeling stuck, tired — and honestly, pretty discouraged.
The thing is, it's probably not your fault.
More likely, your body’s metabolic signaling has started to slow — especially the hormones that help regulate appetite, fat storage, and blood sugar.
The hormones GLP-1, insulin, and leptin help guide your hunger and energy.
But after 40, those signals can get scrambled — leaving you tired, hungrier, and out of sync with your metabolism.
Stress, poor sleep, and blood sugar spikes only add more confusion.
That’s why “just eat less” doesn’t work like it used to.
GLPerfect is designed to support those changing signals — and help your body find its balance again.
“I feel more satisfied throughout the day and I’m not thinking about food as often.” - ✓ Edith R., Verified Buyer
What's Inside GLPerfect
Each capsule of GLPerfect contains three clinically studied nutrients in a highly bioavailable form — chosen for how they support the natural signals behind appetite, metabolism, and blood sugar balance.
✅ Bioavailable Berberine HCl
✅ EGCG (Green Tea Extract)
✅ Alpha Lipoic Acid (ALA)
“After 1 month on GLPerfect and with no major changes to my diet or lifestyle, I’ve seen a 5 lb drop and reduced visceral fat. I wasn’t expecting to see results for several months, so this is exciting to already see a trend in the right direction!”
✓ Amanda, Verified Reviewer

So take advantage of it while you can!
Support for Food Cravings and Metabolism — Without Injections or Stimulants
GLPerfect uses three clinically studied nutrients:
Berberine, EGCG, and Alpha-Lipoic Acid.
All in a form chosen for absorption.
Together, these ingredients support the same metabolic pathways that often become less active or responsive after 40...
Including those connected to GLP-1 signaling. 10,14
All while nurturing your long-term health. 4,13,15
No needles. No prescriptions. No harsh stimulants.
Just smart, targeted support your body can actually use.
ALA is a powerful antioxidant your body makes naturally. It helps turn sugar into energy — so more fuel gets used, not stored as fat.
ALA also helps your body respond better to insulin, the hormone that controls blood sugar. Steady blood sugar may help reduce cravings and support appetite control.
In a group of clinical studies, ALA was linked to about 3 pounds of weight loss — with no big lifestyle changes.
ALA may help your body:
- Boost energy at the cellular level
- Use sugar instead of storing fat
- Support hunger and fullness signals
- Keep blood sugar in a healthy range
Early Reviewers Are Saying...️
When will I receive my bottle?
Most orders will ship within one business day. Most orders take 2-3 days on average to arrive once shipped.
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 designed for absorption through the gut barrier — to support improved bioavailability.
What makes GLPerfect different from other weight support supplements?
GLPerfect is different from other weight support supplements in that the fat-soluble molecules, berberine and EGCG (from green tea extract), are designed to pass through the gut barrier more effectively — supporting key metabolic pathways at the cellular level.
How long will one bottle last?
We recommend taking two capsules per day. One with your first meal and one with your last meal. Taking two capsules a day means one bottle will last you one month.
What are the benefits of GLPerfect?
GLPerfect is formulated to support:
Satiety
Metabolic balance
Fat metabolism
Healthy blood sugar response
Why should I believe that GLPerfect will work for me?
The key ingredients in GLPerfect — berberine, alpha-lipoic acid (ALA), and EGCG — have been studied in dozens of human clinical trials for their effects on metabolic health, appetite, weight management, and fat metabolism. Research supporting these compounds has been published in top peer-reviewed journals, including JAMA, Nature Communications, Diabetes, and Clinical Nutrition.
(Note: These studies were conducted on individual ingredients, not the GLPerfect formula itself.)
Our formula brings these science-backed nutrients together in a format designed for bioavailability.
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, while GLPerfect contains a form of Berberine paired with a different bioavailability support complex.
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.
What ingredients are used in GLPerfect?
Is GLPerfect 3rd-party tested?
Yes. Every batch is tested by an independent lab to verify purity, potency, safety, and heavy metals.
GLPerfect is also non-GMO, gluten-free, soy-free, dairy-free, and vegan. WIth zero stimulants and zero synthetic fillers.
Is GLPerfect made in the USA?
GLPerfect is manufactured in Charlottesville VA by Mara Labs. Our capsules come from Canada and Colombia. 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.
What makes Mara Labs different from other supplement companies?
Mara Labs is a small company based out of Charlottesville, VA. We create, produce, and ship all of our products under one roof, which is rare in the supplement world. We are committed to creating and delivering products backed by evidence-based research to you and your loved ones.

(and Save Up to $151!)
Real Support for Weight and Health — Backed by Science, Not Hype
GLPerfect was formulated by a PhD cellular biologist — not a marketing agency.
Each ingredient has been studied in humans for benefits like blood sugar balance, metabolic support, and oxidative stress.
Some of those studies have been published in journals like JAMA, Diabetes, and Nature Communications.
From there, every batch of GLPerfect is also third-party tested to verify purity, potency, and quality — so you know exactly what you’re putting in your body.
The result? Weight support for women who care about long-term wellness, not just the numbers on the scale.
It curbs my hunger! 5/5 stars
I've been taking GLPerfect for two months, and it's truly helped me a lot. I don't have as many cravings as before, and I've noticed that I don't get hungry as often. I eat because I know I should, but I no longer feel that urge to eat all the time, so it helps me eat only what I need. When I take it on an empty stomach in the morning, it keeps me from feeling hungry throughout the day and allows me to extend my fasts without much effort. I'm happy with this supplement!
✓ Edith R., Verified Buyer
I noticed a sharp reduction in hunger from the first capsules 5/5 stars
I began taking GLPerfect for a couple of reasons... to rein in the sugar cravings from the Holiday season, support my weight goals, and improve how I feel overall. I know some of the deeper effects will take longer, but I noticed a sharp reduction in hunger from the first capsules. In fact, I generally only eat x2 meals a day and find that x2 capsules is plenty to curb my appetite all day! Much easier to skip afternoon snacking! Thanks for this help, Mara Labs. The needle is headed in the right direction! I will be looking forward to upcoming blood tests for more good results!
✓ Rudolph B., Verified Reviewer
Lowest weight I’ve been at for a few years 5/5 stars
I have definitely wanted to eat three meals a day, but I have not found myself wanting any snacks other than water with element in it between meals. The no snacking between meals has been crazy. It's been wild to see the desire gone. I’m at my lowest weight I’ve been at for a few years!
✓ Eric K., Verified Reviewer
I cannot tell you how much I love GLPerfect 5/5 stars
I cannot tell you how much I love GLPerfect. I gained about 10 pounds quickly late last year and was struggling to get it off, so I placed my order right away.
The first day I took GLPerfect, I had 2 pills at 5 pm with supper. The next day around 3:30 in the afternoon, I realized I hadn’t been hungry all day — and all I’d had was my morning coffee!
It’s been a couple weeks and I’ve seen the scale go down by 5 or 6 pounds already!
Yes, GLPerfect has been amazing for curbing my hunger. But more important, it’s curbed my cravings! I have some of my favorite snack foods in the house and — true story — haven’t had the urge to eat even one chip since I started taking it.
I’ve always tended to eat emotionally and occasionally overeat under stress. Since starting GLPerfect, that’s no longer a struggle. It feels like something has shifted in how I relate to food — in just 2 or 3 weeks. I’m so grateful and cannot stop talking about how much I love this product. Thank you!

After using for 4 weeks (update) 5/5 stars
I’ve now been on GLPerfect for about a month and happened to have a full body scan (fat composition, BMI, muscle mass, etc) before starting it, so I went in for another one today. I have weighed the same for the last several years - always about 8 lbs more than “recommended”. but not able to shift much regardless of exercise/diet.
After 1 month on GLPerfect and with no major changes to my diet or lifestyle, I’ve seen a 5 lb drop and reduced visceral fat. I wasn’t expecting to see results for several months, so this is exciting to already see a trend in the right direction!

Insights From Our Scientist and Doctor Co-Founders
Appetite regulation and cravings
Metabolic balance and energy
Blood sugar and insulin function
Healthy digestion and gut support
A healthy weight — as part of a balanced lifestyle
According to research published in 2022, over 93% of U.S. adults are considered cardiometabolically unhealthy. 1
If that's not enough, most women over 40 are also navigating major hormonal transitions.
That can show up as:
- Cravings you didn’t used to have
- Weight gain around the middle
- Afternoon crashes and energy swings
- Diets that “used to work” no longer do
These changes often trace back to subtle shifts in how your body manages appetite, energy, and metabolism.

³ Standard berberine (non-liposomal or non-complexed) has shown low bioavailability in oral form.
⁴ Side effects commonly reported in stimulant-based weight loss products include jitteriness, energy crashes, and sleep disturbance.
EGCG is the star compound in green tea. It can help your body burn more calories and fat, even at rest.
EGCG also plays a role in hunger and fullness. It may lower ghrelin (your “I’m hungry” hormone) and support GLP-1, which helps you stay full longer.
In GLPerfect, we use a supercharged form of EGCG, paired with a patent-pending organic carrier molecule for better absorption.
Early lab tests show up to 225x more bioavailability than regular green tea extract... Which means you may feel more powerful impacts than from standard extracts.
Our EGCG can help:
- Turn on thermogenesis, your body’s calorie-burning engine
- Target deep belly fat
- Cut hunger by working on key appetite hormones
- Support GLP-1 for better control over cravings
- Empower your cells to make and use energy more efficiently
