33Fuel

33Fuel is a British sports nutrition brand founded in 2012 by Erica and Warren. Its range covers fuelling during exercise and everyday nutrition, with Chia Energy Gel, Rocket Fuel carb drink blend, Amore energy bars, Eroica protein bars, protein powders, greens powders and creatine. The brand presents its range as plant-based and describes its approach as real-food nutrition under the Fuelosophy name. These are the company's product and ingredient claims, rather than independent proof of a health or performance benefit. Its own shop offers individual products, bundles and a taster pack. Runners, cyclists and other active customers can compare formats, serving instructions, ingredients and allergens on each product page; the range and stock may change.

Chia Charge

Chia Charge sells sports-fuelling foods including chia-seed flapjacks, smaller snack bars, nut butters and chia seeds. Its shop lists 80 g and mini flapjacks in several flavours, with an original recipe using oats, syrup and sea salt and a berry recipe made with dates and cranberries instead of added sugar. The brand says its flapjacks are made in Yorkshire and markets them as food that can be carried on runs and rides. Different recipes have different ingredients, so the no-added-sugar statement applies to the berry recipe rather than to the whole range.

Grenade

Grenade is a sports nutrition brand best known for protein bars, which it calls the UK's #1 protein bar brand. Alan and Juliet Barratt founded it in 2010 with the aim of creating an iconic weight-loss product; a friend called that first product so effective it was explosive, "like a grenade", and it became Thermo Detonator. Grenade says it is now sold in more than 80 countries with a multi-award-winning range. Mondelēz International acquired a significant majority interest in Grenade in 2021 and includes it in its brand portfolio.
