I had dark patches on my neck and armpits, plus skin tags that kept appearing — new ones every few months. I'd tried every cream, every scrub, even got skin tags removed at the dermatologist. They just came back. After about 5-6 weeks on Nordburn, the patches started looking lighter. And no new skin tags. For the first time in years, no new ones. And here's the thing nobody tells you — I also lost 9 lbs without changing my diet. Turns out the same metabolic imbalance behind my skin issues was also connected to my weight. Two problems, one approach.

How Does Nordburn Capsules Work?
1. Supports the Hormone That Helps Regulate Insulin
Dark patches (acanthosis nigricans) and papillomas (skin tags) are both linked to excess insulin stimulating skin cell overgrowth. GLP-1 is one of your body's primary insulin regulators — it influences how much insulin is released and how effectively your cells respond to it. CQR-300®, the patented active in Nordburn, has been shown to increase GLP-1 levels by up to 56% and inhibit DPP-4, the enzyme that breaks GLP-1 down. By supporting GLP-1 activity, Nordburn supports your body's natural insulin regulation pathway — the same pathway connected to skin changes, blood sugar stability, and fat metabolism.
2. Inhibits DPP-4 to Keep GLP-1 Active Longer
GLP-1 is rapidly broken down in the body by an enzyme called DPP-4. CQR-300® works to inhibit DPP-4, allowing GLP-1 to remain active at higher levels for longer. This extended GLP-1 activity supports sustained insulin regulation — helping your body maintain the metabolic balance that influences both skin health and weight management.
3. Supports the Gut-Skin Connection
Akkermansia muciniphila, a next-generation probiotic in Nordburn, supports gut lining integrity and is strongly linked to increased GLP-1 secretion. Your gut health directly influences your skin — when the gut barrier is compromised, inflammatory signals can enter the bloodstream and show up as skin inflammation, dullness, and accelerated aging. Nordburn supports the gut-skin axis from the inside, a connection most topical skincare products can't reach.
4. Supports Blood Sugar Stability to Protect Skin
Chromium Picolinate supports insulin sensitivity and glucose metabolism, helping reduce post-meal blood sugar spikes. These spikes contribute to glycation — a process where excess glucose bonds to collagen, making it stiff and less elastic. By supporting stable blood sugar, Chromium Picolinate helps protect your skin's collagen from internal damage that no serum or cream can address.

Why Nothing Has Improved Your Skin
-
You Tried Lightening Creams, Exfoliants & Scrubbing
WHY IT FAILED
Lightening creams target melanin on the skin's surface. But dark patches associated with insulin resistance aren't caused by typical melanin overproduction — they're linked to insulin-stimulated skin cell overgrowth from INSIDE the body. Scrubbing, peeling, and bleaching address the surface layer. If the metabolic driver remains, the patches tend to persist or return.
-
You Tried Expensive Dermatology Treatments
WHY IT FAILED
Laser treatments and chemical peels can temporarily improve the appearance of dark patches, and cryotherapy can remove individual skin tags. But these procedures work on the SURFACE. If elevated insulin levels continue sending growth signals to skin cells, the changes tend to recur within weeks or months. You may be paying $200-500 per treatment to manage symptoms while the metabolic driver continues unchecked.
-
You Tried "Clean Eating" or Weight Loss Diets
WHY IT FAILED
Diet improvements are valuable — but diet alone may not fully resolve insulin resistance. GLP-1 production — one of the key hormones involved in insulin regulation — can be influenced by age, stress, gut health, sleep, and genetics, independently of diet quality. Without supporting GLP-1 levels, even a very clean diet may leave part of the insulin-regulation pathway under-supported.
The Missing Piece:
Dark patches, skin tags, and stubborn belly weight are connected to one metabolic imbalance: low GLP-1. Nordburn supports your body's natural GLP-1 production — the hormone behind insulin regulation, skin health, and fat metabolism.

"I cried reading about this product because someone finally explained why my neck looks like this. I thought it was a hygiene problem. I scrubbed until my skin was raw. Turns out it's connected to insulin. 4 weeks in and the patches are starting to lighten. I don't care about weight loss - I care that someone understood my problem."

“I was getting new skin tags every couple of months. My dermatologist would freeze them off and more would appear. Started Nordburn after reading about the insulin connection. 8 weeks in — no new skin tags. The old ones look smaller. Haven't been back to the derm since. Also down 10 lbs which was a total surprise.”

"I've spent hundreds on retinol, vitamin C serums, collagen supplements. My skin still looked dull and aged. A friend told me about the blood sugar-collagen connection. Started Nordburn — within 8 weeks my skin looks brighter and tighter. My aesthetician thought I had a treatment done. Nope. Just this."

"I didn't buy this for weight loss — I bought it for the dark patches on my neck. I've spent over $2,000 on creams and peels that did nothing. After 6 weeks on Nordburn, the patches look lighter than they have in years. Oh, and I dropped 8 lbs without trying. Two problems, one supplement 🙏"

-
Synthetic hormone dependence
Your body relies on the injection instead of restoring its own signals
-
Weight often returns after stopping
Weight bounces back and appetite returns when the medication is removed

Frequently Asked Questions
Find the answers you need right here.
What is this product?
Nordburn GLP-1 Booster is a pharmacist-formulated supplement that supports your body's natural GLP-1 production — a hormone involved in insulin regulation, blood sugar stability, and fat metabolism. Made with clinically studied ingredients including patented CQR-300®, Chromium Picolinate, and Akkermansia muciniphila probiotics, Nordburn provides metabolic support from the inside. Many of our customers sought out Nordburn because of the connection between insulin regulation and skin concerns like dark patches (acanthosis nigricans) and papillomas (skin tags).
How does it relate to dark patches and skin tags (papillomas)?
Dark patches (acanthosis nigricans) and papillomas (skin tags) are both associated in medical literature with elevated insulin levels. Research suggests that excess circulating insulin stimulates skin cell proliferation, which is linked to the appearance of these skin changes. Nordburn supports GLP-1 production, which is involved in insulin regulation. By supporting the metabolic pathway connected to insulin balance, Nordburn provides nutritional support relevant to this area. Results vary by individual. This product does not treat or cure any skin condition.
Will I also lose weight?
Nordburn's ingredients are proven in multiple clinical trials to support weight loss in individuals with a BMI above 26. In a 10-week randomized, double-blind, placebo-controlled clinical trial, participants taking CQR-300® experienced an average of 9% total body weight loss (approximately 15-20 lbs depending on starting weight), a 15% reduction in body fat, and a 27% reduction in body fat percentage compared to baseline. A separate clinical trial showed participants lost an average of 14.1% of body weight over 8 weeks. These weight management benefits are connected to the same GLP-1 and insulin regulation pathway that is linked to the skin concerns described on this page. Many of our customers who came to Nordburn for skin-related reasons report meaningful weight loss as an additional benefit — typically 8-20 lbs over 8-12 weeks — without intentionally dieting.
Can I take this if I have PCOS or an autoimmune condition?
Nordburn is a pharmacist-formulated supplement containing clinically studied natural ingredients: CQR-300® (Cissus Quadrangularis extract), Chromium Picolinate, and Akkermansia muciniphila. It is designed to support GLP-1 production, insulin regulation, and metabolic health.
However, Nordburn is a nutritional supplement — not a medication. It is not intended to diagnose, treat, cure, or prevent any disease or medical condition, including PCOS, autoimmune conditions, or any conditions associated with insulin resistance. If you have any medical condition or are taking prescription medications, please consult your physician before using this or any dietary supplement. Your healthcare provider is the best resource for determining what is appropriate for your individual health situation.
How does it work?
1. Increases GLP-1 for Appetite & Glucose Control
Nordburn GLP-1 Booster helps naturally stimulate GLP-1, a key metabolic hormone that reduces appetite, slows gastric emptying, and improves insulin sensitivity—helping you feel fuller longer while maintaining stable blood sugar levels. This effect is supported by Cissus Quadrangularis (CQR-300®), in recent reaserch, pending peer review, showed to increase GLP-1 levels by up to 56% in overweight individuals.
2. Inhibits DPP-4 to Prolong GLP-1 Activity
GLP-1 is rapidly broken down in the body, but CQR-300® also works to inhibit DPP-4, the enzyme responsible for degrading GLP-1. By slowing this breakdown, Nordburn GLP-1 Booster helps maintain elevated GLP-1 levels for longer-lasting appetite control and improved metabolic response.
3. Enhances Gut Barrier & Microbiome Health
Akkermansia muciniphila, a next-generation probiotic included in Nordburn GLP-1 Booster, is well-established for its role in strengthening the gut lining and enhancing metabolic health. Recent research also indicates a strong link between Akkermansia abundance and increased GLP-1 secretion, suggesting it plays an active role in gut-mediated appetite and glucose regulation.
4. Improves Blood Sugar Stability
Chromium Picolinate improves insulin sensitivity and glucose metabolism, helping to reduce post-meal blood sugar spikes and support fat burning. Stable glucose levels reduce energy crashes, support hormonal balance, and make it easier to maintain a calorie deficit without intense cravings.
How to use?
Proposed usage: For optimal absorption and effectiveness, take 1 capsule of this supplement before a meal, preferably in the morning or before your largest meal of the day. If it causes stomach discomfort, you can try taking it with food. Take supplement with plenty of water (1 cup).
When can I see the difference?
Many users begin to experience reduced appetite and improved craving control within just a few weeks of consistent use. Visible weight loss and fat burn results often begin after 4 to 6 weeks, especially when paired with healthy lifestyle habits. However, individual progress varies based on factors like BMI, metabolic rate, activity level, and hormonal differences.
Third-party clinical trials on a key ingredient in our formula have shown that individuals with a BMI over 26 experienced an average of:
- 9% total weight loss
- 15% reduction in body fat
after 10 weeks of consistent daily use.
For optimal results, we recommend taking the formula for at least three months. Sustainable change takes time — and the results are worth the wait.
