Still get the spikes with a fluctuating blood sugar?

Average glucose doesn’t tell the full story. Post-meal glucose spikes contribute to HbA1c. SIGRID helps support post-meal glucose stability.

I didn’t want medication, just something to help manage my glucose with meals. Sigrid helped me feel fuller and more in control after eating, especially with carb-heavy meals. I snack less and don’t feel driven by blood sugar swings.

I was looking for something safe for daily use that wouldn’t affect my whole system. Sigrid fit that perfectly. It supports my glucose after meals and helps me stay on track without side effects. I plan to keep using it long-term.

Powered by a patented technology

Glucose Stabilizer is a clinically studied supplement designed to support more stable blood sugar after meals — powered by SiPore®, Sigrid’s patented, non-systemic technology.

By slowing the absorption of carbohydrates and fats, it helps reduce post-meal glucose spikes and dips, supporting improved time in range and long-term glycemic control — without interfering with medication.

Faster A1C improvement by supporting post-meal stability

Many people experience large glucose swings, even when average levels appear controlled. A1C reflects average blood sugar over time, and repeated post-meal spikes play an important role.

In a clinical study, SIGRID demonstrated earlier improvements in A1C. Rather than lowering blood sugar directly, SIGRID supports post-meal glucose stability by helping reduce glucose variability which was associated with improved A1C outcomes in the study.

Our patented SiPore® technology works differently

SiPore® works locally in the gut to slow carbohydrate digestion at meals.
By smoothing post-meal glucose responses, it helps support healthier blood sugar balance and more stable appetite control without injections or systemic effects.

Made with one of the most abundant minerals on earth – silica

What's in it?

Our SiPore technology contains one single ingredient – silica. One of the most abundant minerals on earth, which is naturally found in a wide variety of plant-based foods, herbs, and water sources.

Because silica exists naturally in food, the body is already used to it.

It is non-systemic, meaning it is not absorbed into the bloodstream and passes through the digestive system naturally.

What we've done with it

Not all silica is the same. What matters is how it's structured.

SIGRID uses SiPore®, a patented, bioengineered silica with a precisely engineered porous structure.

These pores are designed to interact with digestive enzymes, helping slow the breakdown of carbohydrates and fats for more balanced digestion.

SIGRID vs Metformin

Metformin is a cornerstone of glucose management and plays an important role in lowering average blood sugar. However, many people still experience daily highs and lows that can keep HbA1c elevated.

SIGRID is designed to complement medication, not replace it by helping reduce glucose variability and support steadier blood sugar throughout the day.

A clinically grounded approach to better A1C control

The patented SiPore® technology behind Sigrid has been clinically evaluated for glucose stabilization. By slowing the absorption of carbohydrates and fats in the gut, it helps reduce post-meal glucose spikes and dips, supporting improved time in range and more stable blood sugar over time.

The journey to healthier A1C with SIGRID

Sigrid supports healthier A1C by helping stabilize post-meal blood sugar and reducing glucose spikes that contribute to elevated A1C over time. This can also help reduce cravings and energy crashes linked to glucose fluctuations.

Some people notice smoother post-meal blood sugar within days to weeks. Changes in A1C are typically assessed after about 3 months of consistent use, since A1C reflects longer-term glucose patterns.

Sigrid works locally in the gut to slow carbohydrate digestion, helping reduce sharp glucose spikes after meals. This leads to smoother post-meal curves and more stable energy throughout the day.

The Sigrid Glucose Stabiliser is a clinically proven (x6 times), science-backed dietary supplement containing SiPore® – our patented silica formula, which slows down digestion of carbs and fats, and reduces the uptake of calories in the gut.

Take two capsules with a glass of water together your first bite of each meal, twice a day, preferably with lunch and dinner.

Yes, more than 15 years of research lies behind the patented SiPore® technology, which has been proven efficacious in several clinical trials. If you wish to read more about our science – click here

No serious side effects have been reported in our extensive clinical and consumer trials. Our SiPore® natural mineral, the only active formula in Glucose Stabiliser, undergoes a stringent purification process and also has a self-affirmed GRAS (Generally Recognized as Safe) determination, demonstrating its safety based on criteria established by the FDA.​

What makes Glucose Stabiliser so powerful, in comparison to other alternatives, is that you will notice a difference in your glucose spikes after your first meal. If you track your glucose with a CGM (Continuous Glucose Monitor) , this will become evident very clearly.

For the best long-term effects in regards to weight management and daily energy, we recommend at least 3 months of use.

Glucose Stabiliser can generally be taken alongside other medications or supplements, but timing matters.​ For optimal results and to avoid any potential interaction in the gut, we recommend taking Glucose Stabiliser at least 2 hours before or after any other medications or supplements taken orally. ​If you’re taking prescription medication or have any concerns, it's always best to check with your healthcare provider before starting with a new product.​
