GlucoGuard is one of our newest and most exciting products. It was developed through the innovative work of scientists who discovered a unique collagen peptide that helps the body manage blood sugar naturally. It’s completely sugar-free, fat-free and derived as a collagen, yet the science behind it is quite remarkable.
Most people know collagen for its benefits to skin, joints and hair, but GlucoGuard is a very specific type of collagen peptide. GlucoGuard contains a patented peptide called Nextida™ GC, developed by scientists who discovered that certain collagen-derived peptides can support the body’s own blood-sugar regulation system. Unlike ordinary collagen, this particular peptide works in the gut, where it helps stimulate the release of a natural hormone called GLP-1.
How GlucoGuard works
GLP-1 plays a major role in how your body handles sugar after you eat, it slows down stomach emptying, helps insulin work more efficiently and promotes a sense of fullness after a meal. By supporting this natural pathway, GlucoGuard helps smooth the sharp rises and falls in blood sugar that many people experience after eating, without any artificial ingredients or stimulants. 5g taken 20-30 minutes before a meal, the peptide travels to your gut where it naturally encourages the release of certain hormones which supports:
- How quickly food leaves your stomach
- Support healthy insulin release
- Reduce the spike in blood sugar after meals
- Signals fullness to your brain, helping you feel satisfied sooner
In other words, it does not “force” your body to do anything unnatural. It simply helps your system work the way it’s meant to.
The research
This special peptide was identified after years and years of studies. They screened hundreds of natural peptide sequences “and found one unique profile could influence GLP-1 activity in a positive way.
As stated by Grasset et al. (2024) “A selection of specifically developed collagen hydrolysates was screened for their ability to enhance natural GLP‐1 production in vitro.” They then tested the selected peptide in normogenic animal models and pre-diabetic mice, the peptide increased active GLP-1 after dosing (217% in normogenic group and 860% in the pre-diabetic group). After seeing the benefit, scientists have since done a small, but incredible, study in 16 humans (mix of normoglycaemic and pre-diabetic). Participants took the peptide 30 minutes before a mixed meal at 5g or 10g doses.
- Glucose spike: Both 5g and 10g lowered the post-meal glucose spike, with an average reduction of 42% versus placebo
- Effects were measurable immediately after the meal when the peptide was taken beforehand.
A larger human study is in the pipeline and we are looking forward to seeing even more detailed results on how this remarkable collagen peptide supports post-meal glucose control and natural GLP-1 activity. Early findings are incredibly encouraging, showing that even a small, food-based peptide can make a meaningful difference in the way the body handles sugar after meals.
How to use GlucoGuard
- Mix two scoops (about 5g) into water 20-30 minutes before your main meal, ideally the meal with your highest carbohydrate content.
- It can be used daily, and has a consistency and texture similar to that of collagen.
Who might benefit from GlucoGuard
- Anyone who struggles with mid-afternoon energy dips or sugar cravings
- Those who feel tired or sluggish after eating
- Those who want to support balanced insulin and glucose responses
- Individuals managing insulin resistance or blood-sugar fluctuations
- Anyone wanting a natural way to support appetite control and steady energy
Why we love it
- Pure collagen peptide- no sugar, fat, fillers or flavourings
- Backed by human clinical research
- Safe for daily use and gentle on digestion
- Heat-stable- easy to use in hot or cold drinks
Frequently Asked Questions
Q: Can I take GlucoGuard with my regular collagen?
A: Yes! GlucoGuard targets blood-sugar balance, while other collagens (like Pure Hydrolysed Collagen or Super Chicken Collagen) focus on skin, joints and general tissue repair. They work beautifully together.
Q: Do other proteins have the same effect?
A: A 2023 systematic review and meta-analysis in The American Journal of Clinical Nutrition concluded that whey pre-meals lower post-meal glucose, slow gastric emptying and raise insulin with typical doses using 20-30g. Whey pre-loads are effective, but they generally require 20-30g protein and add calories. GlucoGuard aims for a similar gut-hormone pathway (supporting GLP-1 signalling) with just 5g of a targeted peptide, no sugar and minimal calories, making it a lower-volume, easier option before meals.
Q: Is it suitable for diabetics?
A: GlucoGuard is sugar-free and designed to support healthy post-meal glucose levels naturally. If you use glucose-lowering medication, it’s always best to monitor your levels and speak with your healthcare professional first.
Q: Can I take it with coffee?
A: Absolutely. It dissolves perfectly in hot drinks, and because it’s unflavoured, it won’t affect the taste of your coffee or tea. However, we generally recommend taking it with plain water, rather than with a drink that contains protein, milk or carbohydrates. These nutrients can start digestion early, which may reduce how effectively GlucoGuard reaches the small intestine, the place where it naturally supports GLP-1 release and helps regulate blood sugar. Having it with water 20-30 minutes before your meal gives the best results.
Q: Is GlucoGuard a weight-loss product?
A: Not directly, but many people notice reduced cravings and improved satiety, which can make maintaining a balanced diet easier over time.
