Where do the ingredients in your energy bars and gels actually come from?
From corn monocultures to West African cocoa farms, the supply chain behind your energy bars and gels runs further than the label suggests. Here's what's actually in there, where it comes from, and what to look out for.
Pick up a flapjack, a protein bar, a box of energy chews, a tub of recovery powder, or a gel, and you are holding the same basic question. Where did the carbohydrate, the protein, the flavouring, and the binding ingredients actually came from?
Pull on the ingredients list and the thread runs a lot further than the shelf you bought it from, through farms, fermentation plants, and processing facilities scattered across several continents, most of which never make it onto the label.
What's actually inside
A typical energy product is built around a small set of recurring components, whatever the format. Bars usually combine a binder, such as glucose syrup, golden syrup, or honey, with oats, dried fruit, and nuts, sometimes with a whey, soya, or pea protein isolate added for a protein-specific range.
Gels and chews lean more heavily on a carbohydrate blend, usually maltodextrin, a starch that has been broken down into shorter chains so the body can absorb it quickly, alongside fructose or glucose. Citric acid is added for tartness and as a natural preservative, and many gels include sodium citrate or other electrolytes.
The harder-effort or "plus caffeine" versions, in both bar and gel form, add a measured dose of caffeine. Flavouring ranges from synthetic compounds to, in chocolate, mocha, and salted caramel variants, genuine cocoa solids or dairy-derived ingredients. Packaging differs by format too, which comes it's own sustainability challenges.
Where the carbohydrate comes from
The carbohydrate blend, and the binder in a bar, is where the agricultural footprint starts. At the centre of this is monoculture farming - the practice of growing a single crop across large areas of land year after year.
This practice can be hugely environmentally damaging. Continuous single-crop growing depletes soil organic matter and microbial life over time, because there is no rotation of root structures or nutrient demands to let the land recover between harvests. To keep yields up regardless, monoculture systems depend on heavy and repeated applications of synthetic fertiliser and pesticide, and a significant share of that fertiliser is never taken up by the crop.
Surplus nitrogen and phosphorus wash off the field as runoff and into rivers, where they fuel algal blooms that starve waterways of oxygen and damage the fish and invertebrate life that depends on them, a process known as eutrophication. The same intensively farmed land also tends to support far less biodiversity above ground, and has been linked to declines in pollinating insects and in predatory species, such as ladybirds, that would otherwise help keep pest numbers in check.
Corn-derived maltodextrin and dextrose, glucose syrup, and golden syrup are the products most directly tied to this kind of large-scale monoculture. Tapioca-derived maltodextrin, an alternative to corn, is processed mainly from cassava grown in Thailand and Vietnam, where land conversion for cassava production has been a recurring concern for forest cover.
Sugar tells a similar story on both sides of the Atlantic. Cane sugar, grown predominantly in Brazil and India, carries the water-intensive irrigation and, in some regions, historic deforestation that comes with cane expansion. UK-grown sugar beet is not automatically the cleaner, home-grown alternative it can appear to be: a neonicotinoid pesticide highly toxic to bees, banned for outdoor agricultural use in 2018, has repeatedly been granted "emergency authorisation" for use on sugar beet seed, prompting opposition from conservation charities including The Wildlife Trusts.
Locally-grown does not automatically mean lower-impact.
The chemistry that isn't on the front label
Citric acid sounds like it comes from citrus fruit. In practice, almost all of the citric acid used in food and sports nutrition is produced by fermenting corn-derived sugar with a mould called Aspergillus niger, mostly in large fermentation plants in China, which has become the world's dominant citric acid producer. That ties a "tart" flavour note back to the same corn supply chain already supplying the carbohydrate, rather than to an orchard.
Caffeine works similarly. Most of the caffeine added to gels, chews, and caffeinated bars is not brewed from coffee at the point of manufacture; it is recovered during the decaffeination of ordinary coffee beans, purified, and sold on as a refined powder to the food, pharmaceutical, and supplement industries. That links a product's caffeine content back to coffee farming, where the shift from traditional shade-grown coffee, cultivated under a forest canopy, to high-yield, sun-grown plantations has been a significant driver of deforestation in coffee-growing regions of Latin America, Africa, and South East Asia.
How far it travels before it reaches the shelf
By the time these separate ingredient streams reach a manufacturer, most have already crossed at least one ocean: corn-derived maltodextrin from a wet-mill in the American Midwest, citric acid from a fermentation plant in China, caffeine extract recovered from beans grown in Latin America or East Africa, almonds from California's increasingly water-stressed Central Valley, dates and dried fruit from North Africa or the Middle East, cocoa flavouring from West Africa via a European processor.
Every one of those legs adds transport emissions on top of the farming footprint already built into the raw ingredient, and every change of hands between farm, processor, trader, and manufacturer makes it harder for any single brand to say with confidence exactly where a given batch of material originated.
Flavourings brings their own supply chain
Chocolate-coated bars and chocolate, mocha, or salted caramel gels usually rely on real cocoa solids or cocoa-derived flavour compounds rather than synthetic flavouring alone, and cocoa carries some of the most well-documented sourcing problems in any food category.
The majority of the world's cocoa is grown in Ghana and Côte d'Ivoire, where child labour on smallholder farms and deforestation linked to the search for fresh, fertile land remain structural problems in the supply chain that feeds most major chocolate and flavouring manufacturers. A small number of brands, among them the Dutch chocolate maker Tony's Chocolonely, have built their sourcing model specifically around guaranteed living-income pricing and long-term farmer contracts to address this, and report meaningfully lower rates of child labour within their own supply chain as a result.
However, they remain the exception. Most cocoa-derived flavouring bought by food manufacturers, energy bar and gel producers included, moves through ordinary commodity trading channels that offer no equivalent guarantee and little ability to trace a specific batch back to a named farm.
A note on packaging
The sustainability problems associated with packaging for these products are real and complex, particularly for gels, where the multi-layer laminate needed to keep an acidic, viscous product shelf-stable has no viable end-of-life pathway through UK kerbside recycling. We have covered that problem, and what brands and athletes can actually do about it, in a dedicated explainer on sports nutrition packaging. Most are a laminate of different materials bonded together for shelf life and barrier protection, which is exactly the kind of material standard recycling cannot easily separate.
Farming beyond commodity
Organic certification has been the established standard for lower-input farming for decades. In the UK, the Soil Association has been certifying organic producers since 1973, and organic standards are legally defined, independently audited, and widely recognised by consumers. What organic certification guarantees is the absence of synthetic pesticides, herbicides, and fertilisers on certified land: a meaningful and verifiable commitment that directly addresses the monoculture inputs described above.
For oats, wheat, dried fruit, and the other whole-food ingredients in bars and chews, organic certification is the most robust, widely available signal that the farming behind an ingredient was meaningfully different from commodity convention. A number of sports nutrition brands such as TORQ already use certified organic ingredients, and it is one of the clearest things an athlete can look for on a label.
Regenerative agriculture takes a different emphasis. Where organic certification defines what farmers must not do, regenerative approaches focus on what farmers actively build: soil organic matter, microbial biodiversity, water retention, and above-ground wildlife habitat, typically through practices such as reduced tillage, cover cropping, and integrating livestock into arable rotations. Regenerative farming is newer as a formal category, and the certification landscape is still developing: schemes such as Regenagri and Regenerative Organic Certified (ROC) exist, but are not yet as widely adopted or consumer-recognised as organic.
In practice, many certified organic farms are already farming regeneratively, and many regenerative farms are not yet organic-certified. The two overlap considerably. Wildfarmed, a UK grain company working with around 150 arable farmers, is one of the more visible examples of regenerative sourcing reaching commodity ingredients at scale: TRIBE's flapjack range uses 100% Wildfarmed oats with farm-level traceability.
The practical question for a sports nutrition brand is not necessarily which approach is better. It is whether the farming behind the ingredients is documented at all. Right now, for most brands in this category, it is not.
Where this leaves you
None of these certifications solve the traceability problem on their own, and farm-level transparency of the kind clothing brands now publish as standard is still rare in sports nutrition (or indeed the wider food industry). That is a structural gap across the category, not a failure of intent by any individual brand.
For athletes who are looking for more sustainable nutrition products, Ethical Endurance's sports nutrition buying guide assesses well-known performance nutrition brands against our full Ethical Endurance Framework, including ingredient sourcing, organic certification, palm oil policy, and packaging, across bars, gels, chews, and hydration products.
At the time of assessment, all nine scored in the Listed band, the lowest of the framework's four rating tiers. That is not a verdict on any one brand's ingredients. It reflects how early this category still is in publishing the kind of evidence that would let anyone judge for themselves.
