It's a safe, all-natural supplement that works locally in your gut and never enters your bloodstream.
Whether you're managing blood sugar, or just want steadier energy after meals - it's designed for everyday use. We always recommend consulting with a healthcare professional if you have any known medical conditions, take medications, are pregnant, or have any concerns.
Modern meals are absorbed faster than any meal humans have historically eaten. Fast absorption means sharp blood sugar spikes. Then crashes. Then hunger. Then you eat again. The cycle runs your day.
Glucose Stabilizer slows the speed.
SiPore® works locally in your gut during digestion. It temporarily interacts with the enzymes that break down carbohydrates and fats, slowing absorption so your blood sugar rises gradually instead of spiking. This means no post-meal energy crash, no 3PM brain fog, no cravings between meals, and steady energy for hours after eating. You're not fighting hunger. You're changing how your body processes food.
Take two capsules with a glass of water at the start of each meal, preferably with lunch and dinner.
For best results, take it consistently with your two largest meals of the day. Most people notice a difference after their first meal, but the full effect builds over the first week. You can take it with any meal, any time. It works on a meal-by-meal basis, so there's no build-up period required.

"I used to crash every day around 3PM. Didn't matter what I ate for lunch - pasta, sandwich, salad - two hours later I'd be exhausted and raiding the snack drawer. Started taking Glucose Stabilizer with my meals and the difference is night and day. My energy stays steady from lunch straight through to dinner. I can actually focus at work in the afternoon now."

‘’I wear a glucose monitor and I've watched my blood sugar spike and crash for months. It's been exhausting. I started taking this with lunch and the difference on my CGM was immediate. The sharp spikes are gone. Just a smooth, steady curve. My energy doesn't crash at 3PM anymore. I can actually focus through the afternoon.’’

‘’I've struggled with high blood sugar for years and nothing seemed to help keep it stable. I'd eat a normal meal and feel exhausted an hour later. I started taking Glucose Stabilizer with every meal and the difference was incredible. My blood sugar stays so much more stable now. No more crashes. No more brain fog.’’

"I used to snack constantly between meals. I'd eat lunch and two hours later I'd be starving again, raiding the fridge. Since taking Glucose Stabilizer with my meals, the cravings just stopped. I'm genuinely full for four or five hours after eating. It's honestly wild how much easier everything became."

THE PROBLEM
Modern Meals Digest Too Quickly
Refined carbs, processed foods, and sugar-heavy meals break down quickly. This can lead to a rapid rise in blood sugar, followed by a drop a few hours later, leaving you hungry, low on energy, and reaching for snacks.
SiPore® works locally in your gut during digestion. It does not enter the bloodstream and is designed to reduce the impact of the food you eat.
Patented SiPore® Technology
Turning Fast Food Into Slow Food
SiPore® slows carb and fat digestion in your gut, promoting a steadier response in blood sugar, instead of spiking.

FAQS
Frequently asked questions
Glucose Stabilizer uses patented SiPore® technology to work locally in your gut. It entraps digestive enzymes (alpha-amylase and lipase) that break down carbs and fats, helping slow how quickly your meal is processed.
This leads to a more gradual release of energy after eating, supporting a steadier post-meal experience. SiPore® does not enter the bloodstream and passes through the body naturally.
Many users report noticing a difference from their first meal, especially in how steady they feel after eating. In clinical evaluation using continuous glucose monitoring (CGM), a more gradual post-meal response has been observed. For best results, consistent use over time is recommended.
SiPore® technology has been evaluated in 6 human studies over more than 15 years. These studies show its ability to support a more gradual post-meal response, along with improvements in blood sugar levels, energy patterns and appetite regulation.
SiPore® works locally in the gut and does not enter the bloodstream. It is generally well tolerated, and many users report a gentle experience when taken with meals.
You can take it long-term as part of a healthy lifestyle. Many people use it daily for steady energy, appetite control, and metabolic health. Consistency is key for best results.
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.

I do find that I feel bloated but it does help with sugar cravings and I feel full sooner. I am on vacation so can’t weigh myself to see if there is any loss. It’s hard to tell as my stomach is often bloated. I am also very disappointed that I decided to skip the trial pack and just subscribe only to find if I had waited to subscribe I could have had a substantial discount on my first order. When I asked about applying it to my next shipment I was told no. I think that’s pretty unfair.
I started Carb Fence because I have difficulty with snacking especially in the evenings. I have lots of food noises in the evening and it is worse if I am tired or have been working hard in the garden due to the extra physical work. Before starting Carb Fence, I would just keep eating. Within a week of starting Carb Fence, the food noises went away almost completely. I am now in my fourth week of taking Carb Fence. I can ignore what little food noises went there is. On days when I work in the garden and I need more calories, I eat a modest number of extra calories instead of snacking all evening. I have been tracking my calories and am now consistently under my calorie goal 6 days each week and only over by about 50 on the 7th day - usually from going out to eat. I have lost 2.5 pounds in 3.5 weeks with Carb Fence. (I gained 15 pounds in the 12 months before starting Carb Fence so this is a big deal for me.) I have more energy mentally and physically so other aspects of life are improving as well. I am looking forward to the next month with Carb Fence.
It does exactly as promised. The food noise is gone and I have no desire to snack. I am eating less and feeling full. No negative side effects at all. I have lost almost 5 pounds in 3 weeks. The cost us quite reasonable. I'm so happy to have found Sigrid.
Sigrid really helps in suppressing your appetite. Even if there were food in front of me, I was not tempted to eat any. I feel fuller and does not get hungry for hours. I love Sigrid!
This works. I don’t write reviews. I had already lost about 20lbs but was struggling with the final 5-8lbs. I would lose a little and drift right back up. Carb-Fence was a total game changer to get me over the hump. It stabilized my blood sugar and I assume that meant also my insulin. After a couple of weeks… yes the weight started to drop again but more importantly…. the fat . I was keeping the muscle and shedding the fat. Now I’m at my goal weight and it’s helping me stay there. For me “maintenance” can be harder than losing. This product has allowed to expand my diet without completely sabotaging my weight loss. I’m a convert.
Product works as promised. Consume one packet followed by a full glass of water. Feel full quickly. Urges to eat sugar decreased significantly. Weight loss consistent.
It took about a month for me to see a difference , i think i have now lost a few pounds. Some days i feel like it helps with appetite control and a feeling of fullness. I hope that my journey continues in this direction !
I ordered the trial pack and have only used it about five times, but I have noticed a reduction in my post meal glucose readings when I have had carbs. There was only one time when I had carbs and I took Carb Fence before eating that my glucose reading was still over 160 post meal, which is pretty high for me. I am new to this diagnosis, so I haven't had much experience tracking my numbers and I would have to use it several more times to be sure it's beneficial to me. It looks positive so far.
Although I have not lost weight in the couple of months I have been using CarbFence, it is has definitely gotten rid of the gnawing in my stomach that could never get satisfied. It also helps with staving off hunger pangs, if I listen to my stomach and not the psychological needs.
I started Carb Fence almost 1 month ago.
There are absolutely no adverse side affects that I have experienced. I was a little apprehensive at first because I do have digestive issues. However because it is FDA approved and considered food grade and not a drug, I was a little more confident in trying.
Then when the case came in,also I was a little leery about trying it, not knowing how it would taste. Let me assure you, the taste is refreshingly good, and I don’t “dread” having to take it before meals.
The greatest part of all of this is that I have actually lost 5 lbs. I’m not trying to lose a great amount of weight, but I am now 5 lbs closer to my goal.
The cost is not a great concern for me, but I did purchase the discount bulk quantity, and having the extra boxes on hand helps.
If I lose another 5 lbs while using Sigrid Carb Fence, I will most likely continue taking the gel indefinitely because I do feel as though the product has assisted me with hunger control & not absorbing carbs..
Thank you SIGRID for creating a safe non-drug product to enable people who are looking for an alternative to GLP-1 treatment.
This product worked very well for me. My fasting BS went from 130 to 115 and my after meal BS went from around 200 to 150! I, however, was approved for the new Wegovy Medicare D program and was advised to discontinue the glucose stabilizer until I have a better idea of my BS.
I have taken Sigrid with low calorie diet and lost 1 lb weekly for 6 months. I have now stuck for 3 months but continue the same regime to maintain weight. I highly recommend for appetite control.
It actually works. Still use common sense of course...but if you want a slice of pizza, or a few bits of desert when out with friends, it limits the amplitude and duration of the spike. Keeps things within the "green zone" for me. Kept some with me at all times on last week's trip to Boston. Warning...there are "anti spike" concoctions out there...they didn't do anything for me (and I canceled). I also think it's helped my weight loss! SIGRID really works.
I like the way a lot of my cravings have become less and less but I have not lost a pound yet and it is very expensive. Please do not send me any more product. I want to cancel future orders. Thank you,
