ATP Science GOODGUT™ Gut Support Powder

ATP Science GOODGUT™ — Your Daily Gut Glow-Up. Fibre, Enzymes, Prebiotics and Postbiotics. Once a Day.

GOODGUT™ is ATP Science's daily gut support powder — a 7g blackcurrant or tropical berry blend that covers four layers of gut health in a single once-daily scoop: a 50% fibre formula, prebiotics, postbiotics, and a multi-enzyme complex. Built for everyday digestive regularity, bloat relief, and a balanced gut microbiome. No added sugar, no polyols, no artificial anything. Dairy-free, gluten-free, nut-free, non-GMO. Mixes into water, yoghurt, or smoothies. 210g / 30 serves. In stock now at Pro Supplement.

Four Layers of Gut Support in One Scoop

Most gut health supplements do one thing — fibre, or a probiotic, or enzymes. GOODGUT™ covers all four simultaneously, which is what daily gut maintenance actually needs:

• Fibre (50% of the formula) — the single largest component by weight, split between two premium forms: Fibalance™ Partially Hydrolysed Guar Gum (PHGG) and Acacia Fibre. Both are soluble fibres that feed beneficial gut bacteria (prebiotic function), support regularity, and are low FODMAP — meaning they're suitable for sensitive digestive systems that react to standard fibre sources.
• Prebiotics — the Polyphenol Blend — 13 plant-derived ingredients including Actazin® NZ green kiwi, apple fibre, nutmeg, broccoli, cranberry, ginger, black cherry, pomegranate peel, rosemary, Schisandra berry, cinnamon, acai and cabbage. These provide the plant polyphenols and phytocompounds that selectively feed beneficial gut bacteria — the same dietary plant diversity that modern diets consistently lack.
• Postbiotics — FloraSMART™ — a heat-killed Lactobacillus casei 327 strain at 25 billion CFU per serve. Postbiotics are the bioactive compounds produced by gut bacteria — FloraSMART™ delivers these directly without the survival and colonisation variability of live probiotic strains. Clinically studied in two randomised controlled trials for its role in supporting digestive regularity and serotonin synthesis in the colon.
• Digestive Enzymes — DigeZyme® — a clinically developed five-enzyme complex: α-Amylase (carbohydrates), Protease (protein), Cellulase (plant fibres), Lactase (dairy), and Lipase (fats). Together they support the breakdown of all major macronutrient types, reducing the digestive burden and supporting nutrient absorption at every meal.

Actazin® — New Zealand Green Kiwi Powder

Actazin® is a clinically studied NZ green kiwi ingredient — and its inclusion in GOODGUT™ is a genuine differentiator. Kiwifruit contains actinidin, a protease enzyme unique to the fruit that supports protein digestion and nutrient absorption. Beyond actinidin, Actazin® provides both soluble and insoluble prebiotic fibre alongside the natural polyphenol profile of green kiwi — clinically shown to support bowel regularity and digestive comfort. The fact that it's sourced from NZ-grown kiwifruit is a relevant talking point for the NZ market.

FloraSMART™ — The Postbiotic Distinction

Most gut health products use live probiotics — bacteria that must survive manufacturing, shelf life, and stomach acid to reach the gut. FloraSMART™ uses a heat-killed (postbiotic) strain, which sidesteps those survival challenges entirely. The bioactive compounds are stable, consistent serve-to-serve, and deliver their benefits without the variability of live cultures. The clinical research behind FloraSMART™ (Lactobacillus casei 327) includes a randomised double-blind placebo-controlled trial showing improved defecation frequency and regularity, and a separate study showing increased colonic serotonin synthesis — which has implications for gut motility and mood.

How GOODGUT™ Differs From GutRight®

Both are ATP Science gut health products but they serve different functions. GutRight® is the intensive Modbiotic® gut reset — 21 plant-derived compounds targeting the microbiome at a structural level, with clinical data showing 72% E. coli reduction and 66% Bifidobacterium increase over 10 days. GOODGUT™ is the daily maintenance formula — fibre, enzymes, a postbiotic and prebiotics for everyday digestive regularity, suited to long-term daily use from day one without the intensity of a clinical reset protocol. Used together: GutRight® for the initial microbiome reset, GOODGUT™ for ongoing daily digestive support afterward.

Low FODMAP Friendly

Both the PHGG and Acacia Fibre components of the fibre blend are low FODMAP, making GOODGUT™ suitable for people with IBS or sensitive digestive systems who have historically reacted to other fibre supplements. The DigeZyme® lactase enzyme also supports those with mild lactose sensitivity.

How to Use It

Mix 2 flat scoops (approx. 7g) into 250ml of water, or stir into yoghurt, a smoothie, or your favourite meal. Take once daily. For a kick-start: 3 serves per day for the first 10 days, then 1 serve per day for ongoing maintenance. Reviewers describe mixing it into Greek yoghurt, smoothies and water bottles — the flavour works in all three.
