Frequently Asked Questions

Discover the answers to your frequently asked questions about Carb Fence.

Carb Fence™ is a medical-food appetite-control gel designed to support weight management, stabilize post-meal blood sugar, and reduce cravings. It is powered by SiPore®, a patented non-systemic silica technology that works locally in the gut to slow the breakdown of carbohydrates and fats, without entering your bloodstream.

Unlike stimulants or appetite suppressants, Carb Fence™ works mechanically in the digestive tract. The SiPore® compound forms a gel matrix that slows carbohydrate and fat digestion, which blunts glucose spikes, extends satiety, and supports a gradual calorie reduction over time. It also helps preserve lean muscle mass during weight loss. Learn more about the science behind SiPore here!

Carb Fence™ is designed for adults who experience frequent glucose spikes and crashes. It's particularly well suited for people looking to manage their weight, reduce cravings, stabilize energy levels throughout the day, or support overall metabolic health.

Most people experience glucose irregularities daily without being aware of it. These fluctuations are commonly associated with:

  • Sugar cravings and difficulty resisting snacks
  • Energy crashes and fatigue after meals
  • Brain fog and difficulty concentrating
  • Bloating and poor gut health
  • Difficulty burning fat despite a balanced diet
  • Hormonal imbalances
  • Skin issues such as acne or eczema
  • Poor or unrestful sleep

If you recognize several of these symptoms, blood sugar variability may be a contributing factor. Carb Fence™ helps smooth these fluctuations from the very first meal.

If you have a diagnosed condition such as type 2 diabetes or are taking prescription medication, consult your healthcare provider before starting.

Take one sachet with a full glass of water before each main meal. Typically breakfast, lunch, and dinner for a total of three sachets per day. Consistent daily use is key: for weight management and sustained energy benefits, we recommend at least 90 days of use.

A few tips for best results:

  • Take the sachet 5–10 minutes before eating, not after
  • Always take it with a full glass of water to allow the gel to form properly
  • If you miss a dose, skip it and resume at your next meal — do not double up
  • If you are taking other oral medications or supplements, space them at least 2 hours apart from Carb Fence™

Yes. Carb Fence™ and its active ingredient SiPore® have been evaluated across six pre-clinical and clinical trials. These studies confirm reduced post-meal glucose excursions, improved satiety, and support for weight reduction, giving Carb Fence™ one of the strongest evidence bases of any appetite-control product on the market.

The research spans multiple study types, including in-vitro work, animal studies, and human clinical trials. Key findings include:

  • Statistically significant reductions in post-meal blood glucose peaks
  • Increased feelings of fullness and reduced caloric intake over time
  • No systemic absorption of SiPore®, it passes through the digestive tract without entering the bloodstream
  • A safety profile consistent with GRAS (Generally Recognized as Safe) status under FDA criteria

All studies were conducted or reviewed by independent researchers and have been published in peer-reviewed journals.

No serious side effects have been reported in clinical or consumer trials. SiPore®, the only active ingredient in Carb Fence™, is non-systemic, it works entirely within the gut and is never absorbed into the bloodstream. It holds a self-affirmed GRAS determination, demonstrating its safety based on criteria established by the FDA.

SiPore® is a purified mineral silica that goes through a stringent purification process before use. Because it acts mechanically rather than chemically, it does not interfere with hormones, the nervous system, or systemic metabolism.

Some individuals may notice mild digestive changes, such as a feeling of fullness or slightly altered bowel habits, during the first few days of use as the body adjusts. These typically resolve on their own.

If you have a pre-existing digestive condition or are taking prescription medication, speak with your healthcare provider before starting.

Carb Fence™ begins working from your very first meal. It blunts post-meal glucose spikes immediately, something you can observe within hours if you track your blood sugar with a CGM (Continuous Glucose Monitor). For weight management and sustained daily energy, allow at least 90 days of consistent daily use for full results.

The two-phase effect works like this:

Immediately (meal 1 onwards): The SiPore® gel slows carbohydrate and fat digestion, reducing the size and duration of your post-meal glucose spike. Many users notice fewer cravings and less of an energy crash in the hours following meals.

Over 90 days: Consistently lower glucose spikes mean fewer cravings, more stable energy, a gradual reduction in caloric intake, and measurable changes in body composition. Clinical data supports visible fat reduction over this timeframe.

For users with a CGM, the first-meal effect is typically very clear on the graph a noticeably flatter post-meal curve.

Carb Fence™ can generally be taken alongside other medications or supplements. Because SiPore® works locally in the gut, it could theoretically slow the absorption of other oral substances taken at the same time. To avoid this, simply space Carb Fence™ at least two hours before or after any other oral medications or supplements.

This precaution applies to both prescription medications and over-the-counter supplements. If you are taking medication for blood sugar management (such as metformin or insulin) or any other chronic condition, consult your healthcare provider before starting Carb Fence™, not because of known interactions, but to ensure your treatment plan is adjusted appropriately as your glucose levels improve.
