Gastroflux is back with brand new packaging under Metagenics, delivering the same expert formula you trust.

Gastroflux combines GutGard® DGL liquorice with a carefully selected blend of botanicals, including marshmallow, chamomile, fennel, ginger, and lemon balm, alongside L-glycine, to support digestive health and maintain gut pH balance. This targeted formula helps to soothe mucous membranes, promote digestive comfort, and support overall gut well-being, all in a hypoallergenic and convenient tablet form.

Gastroflux contains liquorice, which is known to help maintain balance and comfort in the digestive system. The liquorice is a deglycyrrhizinised liquorice extract (DGL liquorice) in the form of GutGard®, an extract that has a unique composition obtained through a revolutionary manufacturing process. GutGard® is standardised to ≥ 3.5% glabridin, a key pharmacological maker.

Gastroflux also contains marshmallow (Althaea officinalis), which has been shown to have soothing effects, especially for the mucous membranes of the gastrointestinal (GI) tract.

Gastroflux is further enhanced with a herbal blend that includes chamomile (Matricaria chamomilla), which has a long traditional use for digestive complaints due to its calming and antispasmodic properties.

The herbal blend also features fennel (Foeniculum vulgare), which may have a carminative effect on the stomach. Plus, lemon balm (Melissa officinalis) and ginger (Zingiber officinalis), which may both help to support digestion.

Gastroflux contains the amino acid l-glycine. In the body, glycine biologically is needed to help form both collagen and gelatine. These are components of connective tissue which includes the lining of the digestive tract.

A standardised herbal extract is a specific concentration of one or more of the chemical compounds found in the plant. It guarantees that the potency and amount of active compounds contained in the product is the same as those advertised on the label and is consistent from batch to batch.

With standardised herbal extracts, you know you're getting a sufficient amount of the beneficial compound, as determined by scientific evidence.

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.

Orders placed by 2pm Monday - Friday will be despatched the same working day.
