EU-authorised health claims
Weight management supplement claims are one of the most regulated categories in UK law — and for good reason, because most of the market is built on claims that don't survive regulatory scrutiny. BioBurn is built around one of the very few ingredients with an EU-authorised health claim specifically for weight loss: glucomannan. It contributes to weight loss in the context of an energy-restricted diet. This is not a marketing claim — it's a regulatory fact. And it's the starting point for a formula that adds chromium, iodine and green tea to address the metabolic mechanisms that support sustainable weight management.
The EU's health claims regulation (1924/2006) is specific: only glucomannan at 3g per day carries an authorised claim for weight loss in an energy-restricted diet. Garcinia cambogia, raspberry ketones, CLA, L-carnitine — none have EU-authorised weight loss claims. They're sold on marketing language, testimonials, and cherry-picked studies that don't meet regulatory evidence standards. BioBurn is built around the one ingredient that does.
The European Food Safety Authority confirmed glucomannan's weight loss evidence at the 3g daily dose alongside an energy-restricted diet. At this dose, glucomannan's gel-forming fibre expands in the stomach, reduces gastric emptying rate, and produces meaningful satiety — making calorie restriction more sustainable.
XLS Medical Max Strength — cactus fibre, not glucomannan EU claim. XLS Medical uses Litramine (cactus fibre) rather than glucomannan — a different mechanism without the same EU authorised weight loss claim. More expensive and not halal certified.
Healthspan Glucomannan — single ingredient, not halal. A good single-ingredient glucomannan product but without the chromium, iodine or green tea metabolic stack. No halal certification.
Most "fat burners" and "thermogenics" — unregulated claims. Raspberry ketones, synephrine, garcinia — none carry EU-authorised weight management claims. BioBurn doesn't need thermogenic marketing copy because the glucomannan claim is legally authorised. Everything else in the formula supports the metabolic context around that claim.

Take 1 capsule with a large glass of water (250–300ml minimum) 30 minutes before each main meal — 3 capsules daily to reach the EU-validated 3g glucomannan dose. It is essential to take with adequate water as glucomannan forms a gel — without sufficient liquid it can swell in the throat. Always take sitting upright. Use consistently as part of a calorie-controlled diet; glucomannan's authorised claim specifically requires an energy-restricted diet context.
For a complete approach, pair with An Apple a Day ACV for post-meal glucose management alongside BioBurn's pre-meal satiety support. For meal replacement on high-demand days, Shake Me Up provides a nutritionally complete low-calorie meal option.

Glucomannan is a soluble dietary fibre extracted from the konjac root plant (Amorphophallus konjac), native to Asia. When consumed with water before meals, it forms a viscous gel in the stomach that dramatically slows gastric emptying — food stays in the stomach longer, reducing the rate at which appetite hormones fall after eating, and sustaining fullness well beyond what a non-fibre meal provides. It's the only dietary supplement ingredient with an EU-authorised claim specifically for weight loss in an energy-restricted diet.
Yes — glucomannan is a food fibre with an excellent safety profile. The critical requirement is adequate water intake: take each capsule with at least 250ml of water. Without sufficient water, glucomannan can swell before reaching the stomach and cause choking risk. Do not take immediately before bed. For people with swallowing difficulties, consult a healthcare professional before use.
The EU-authorised claim for glucomannan specifically states: "in the context of an energy-restricted diet." Glucomannan makes calorie restriction more sustainable by reducing hunger — it doesn't create a calorie deficit on its own. It's a tool to support dietary change, not a replacement for it. No supplement legally approved in the EU can make an unconditional weight loss claim.
Food supplements should not replace a varied diet or healthy lifestyle. Contains glucomannan — always take with a large glass of water and remain upright for 30 minutes after. Consult your GP before use if pregnant, breastfeeding, diabetic, or taking prescription medication.
Commonly taken before meals with plenty of water.
