Modern meals are
designed for speed and convenience. Your
metabolism was not.
Today's foods are absorbed extremely quickly. For many people this leads to: Energy crashes after meals, constant hunger and cravings, afternoon fatigue, and difficulty managing weight.
It is not a lack of discipline. It is how modern food interacts with our biology.
Reduce the impact of modern meals.
SIGRID Glucose Stabilizer was developed to help smooth the body's response to modern food. With our patented SiPore® technology it works locally in the gut to gently moderate how quickly carbohydrates and fats are broken down.
Benefits reported by users:
Fewer cravings
Reduced snacking
Longer satiety
More stable energy
‘I used to crash every afternoon around 3pm. That’s mostly gone now.’ — Michelle, 36, New York
A medical food designed to support appetite control, reduce cravings, and promote healthy weight loss.Carb Fence™ works locally in the gut to gently slow the breakdown of carbohydrates and fats during digestion. The result is a steadier release of energy after meals, reduced snacking and cravings, and support for sustainable weight management over time.
SiPore® significantly reduced long-term blood sugar (HbA1c) from baseline. It also improved body weight, fat mass, and blood lipids (LDL and total cholesterol), with reduced progression to diabetes and increased reversion to earlier glycaemic states. It was safe and well tolerated.
If you are experiencing any of these symptoms, irregular blood sugar might be what's causing it:
When our glucose levels spike after a meal and then crash shortly after, that activates the hunger craving center in our brain. We feel an irresistible urge to eat sugar. Trying to resist won’t work! The solution is to solve the root cause: glucose spikes.
An unstable glucose response can contribute to gut inflammation, disrupting the microbiome and weakening the gut lining. This can lead to bloating, discomfort, and digestive issues. Glucose stabilizers works as digestive health supplements. Balanced blood sugar supports gut health by reducing unnecessary stress on digestion and promoting a healthier microbiome.
Blood sugar fluctuations can disrupt hormone regulation, impacting everything from stress and energy levels to menstrual cycles and menopause symptoms. Studies show that stabilizing blood sugar can help support a more balanced hormonal system, reducing common symptoms like mood swings and irregular cycles. Glucose stabilizers can also work asPCOS supplements!
When we eat a meal that gives us a glucose spike, our glucose levels crash soon after. This makes us feel tired. If we want steady energy, it’s important to keep our glucose levels steady: avoiding glucose spikes is key.
When blood sugar levels spike, insulin rises—and when insulin is high, the body is less efficient at burning fat for fuel. Keeping blood sugar stable helps optimize metabolism, allowing your body to tap into fat stores more effectively.
Blood sugar instability can disrupt sleep by causing nighttime awakenings, heart palpitations, and difficulty falling back asleep. Elevated glucose levels before bed can also contribute to restless nights. A steady glucose response supports deeper, more restorative sleep.

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,

I really like it. It has a pleasant taste and it makes me feel full so I don’t eat as much. I never feel nauseous and it has not had any side effects on my digestion. I lost 6 lbs the first month without changing my diet and also ate some chocolate. Going on to month 2. Will try to watch what I eat better and see what the results bring.
I think it's working or my glucometer is broken. My fasting BS has gone from 130 to 99! After meals from 190-200 to 140. I have a physical this week and will know more after my blood work.
I’ve been taking Sigrid for 3 months now and I’ve seen a consistent stabilization of my blood sugar. I have a CGM because of insulin resistance and a risk of developing Type II diabetes. I’m unable to tolerate metformin and all of the GLP 1’s, originally designed to regulate A1C before they became miracle weight loss drugs for the non-insulin resistant, made me horribly ill. Sigrid has given me peace of mind. My A1C is routinely in the 5.5 to 6.0 range now, down from 7.5/8, with zero adverse side effects and I don’t fret over everything I eat.
I check my blood sugar especially after a heavier carb meal. If I ingest a packet of Sigrid before a carby meal, my blood sugar remains in range. I am not pre- or diabetic, but my glucose rises higher than I want with high glycemic foods.
Tasty product with no immediate side effects. Blunts glucose response. Sense of fullness. Safe for cardiac and renal patients as it is not absorbed. Supposed to take before meals. You could suck it out of packet or add to foods. Good afternoon snack.
The first couple times gave me slight nausea, nothing unbearable, but after that my meals got smaller and my energy level and even my mood improved! Definitely worth a go!!!
