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.
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.

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:

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.
I don’t know if this does what it claims it should, but I do know that I feel a lot better when I take this, especially when I eat
I can’t afford it but I did love it! I also do not want a subscription
I really have been doing this for almost three months. Works great and keeps the snacking down.
Helps regulate my glucose and I think it helps with sugar cravings.
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.
Losing weight without the medication side effects!
I can’t afford it though and the subscription status is a turn off. I will not sign up for a subscription
Helps quell tendency to eat sweets; helps to focus on nutritious main meal
It seems to work in a gentle way
Easy to take. Taste is good. Helped me.
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.
So far so good!
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.
Since started on this pill it has worked for me my blood sugar has decrease significantly love the product will definitely repurchase.
It works and I love it
Great product, helps with my blood sugars
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.
I have doing this plus a berberine supplement, and my blood sugar levels have consistently been 112 for the past week.
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, Eileen Fuhrmeister Eileen8624@duck.com
This is actually a great product it makes you feel full. Makes you feel better.
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.
Worked great! Take before any meal.
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.
Definitely curbs my appetite and keeps my blood sugar more steady. Starting to see the scale move.
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.
Level glucose.
Great product have started subscription
Great supplement
This stuff works wonders Helps stop cravings and endless eating Highly recommend this
I’m trusting the science behind this product and will hope for some success in keeping my weight down eventually. Trying to be patient.
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!!!
I think it would probably work for me, but I will not pay 180 mo for it. I think a subscription should have a greater discount.
The taste was a little weird and really not sure what it did for me - if anything. Followed the directions.. that's about it.
