Glutagenics® is back with a new name and brand-new packaging under Metagenics, delivering the same expert formula you trust.

MetaDigest® Repair is a targeted gut health formula designed to support the regeneration and integrity of the gut lining. Previously known as Glutagenics®, this science-backed powder combines the soothing properties of L-glutamine with the protective benefits of zinc and quercetin, ideal for those with increased intestinal permeability or gut discomfort.

L-glutamine is the most abundant amino acid in the body and a key nutrient for the fast-dividing cells of the intestinal wall. Zinc supports tissue regeneration, while quercetin acts as a gentle flavonoid to protect the gut lining. The powder format allows for easy mixing in water and is well suited to those who prefer to avoid capsules. Whether you're addressing digestive issues, supporting gut repair post-antibiotics, or following a 5R gut restoration programme, MetaDigest® Repair offers effective, gentle support for a healthy gastrointestinal environment.

This is a blend of the amino acids L-alanine and L-glutamine that has shown superior absorption, stability and solubility when compared to L-glutamine alone. This means the body is able to absorb more glutamine when taken together with L-alanyl-L-glutamine to support the gut lining.

MetaDigest® Repair contains zinc which is a crucially important mineral, that’s involved in all areas of the body. Adequate zinc is necessary for a proper functioning immune system. Zinc also plays an active role in cell division, and is therefore important in wound healing, and also, the replacement and regeneration of the gut lining as these cells are constantly being replaced.

Our new label design has been introduced to help you to find a product that’s right for you, simplifying the way you navigate our range. The new labels provide you with more product information and better highlight the core benefit of each product. For example, you will see new health need colours and descriptions that make it easier to identify ranges and highlights the products main benefit.

Nutri Advanced is transitioning to the Metagenics brand to align more closely with our global family, who we joined in 2022. We have worked closely with Metagenics for decades with many of our products produced from their European Headquarters in Belgium. Metagenics is a global leader in the professional supplements market and is renowned for clinically proven, precision-crafted formulas to support your health. In 2024, they were voted the No. 1 Doctor Recommended Professional Supplement Brand in the US. They also held the No. 1 VMS position in Belgium for their Magnesium product, MetaRelax, and had the most prescribed probiotics brand among health professionals in Italy and Australia.

The change from Nutri Advanced to Metagenics will give you access to even more ground-breaking new product innovations and nutritional resources whilst maintaining our trusted formulations and excellent UK based customer service.
