How supplements for endurance athletes fit together
Endurance training asks three separate things from your nutrition: carbohydrate during the effort, fluid and salt to replace sweat, and a steady daily nutrient base between sessions. Most runners, cyclists and triathletes arrive looking for one of the three and find they need two. This collection is grouped that way, and it sits inside our MOVE + RECOVER pillar.
The fuelling side has the clearest rules in Europe. Approved wording says carbohydrate-electrolyte solutions contribute to the maintenance of endurance performance during prolonged endurance exercise. A second approved wording says they enhance the absorption of water during physical exercise. Both only apply when the drink stays inside a defined range for carbohydrate, sodium and concentration. That is the practical reason we list electrolyte tablets and powders separately from plain flavoured drinks.
Forms differ more than the labels suggest
A gel, a chew and a drink mix can deliver similar carbohydrate and behave very differently in your stomach. Most modern products use two carbohydrate types, usually glucose or maltodextrin with fructose, because the two use different transport routes in the gut and are often tolerated better together at higher intakes. Concentration matters too: a thick gel taken without water sits heavier than the same carbohydrate diluted in a bottle.
- Drink mix: carbohydrate, sodium and fluid in one bottle, easiest to sip steadily.
- Gels: compact and precise, best with a few sips of water. Our gels for long rides and runs vary in thickness, which is mostly a tolerance question.
- Chews and bars: slower to eat, useful on steady efforts rather than in a hard finish.
How we select what goes into this collection
We judge products here on three things: the form, the dose, and whether the combination makes sense for a long effort. A drink mix that dissolves cleanly and empties from the stomach quickly is worth more to us than a longer ingredient list. For daily minerals we prefer better absorbed forms, so magnesium bisglycinate before magnesium oxide, and gentler iron forms for people who react badly to sulphate. We buy directly from the brands, so batches are authentic. Every product passes our compliance team before it goes live, we test products ourselves, and independent labs spot-check batches. Read how we select our brands.
Who this collection suits, and what it will not do
This range is built for people training more than a few hours a week, where sweat losses and carbohydrate needs become real rather than theoretical. If you train twice a week for an hour, food and water usually cover it, and a basic daily nutrient check is more useful than race fuel.
Be realistic about timelines. Fuel and fluid work the same day you use them, and you will notice the difference on a three-hour ride. Nutrient status is slower: iron, magnesium or omega-3 intake changes blood values over weeks, not sessions, so give any daily product two to three weeks of consistent use before you judge it. Iron contributes to normal oxygen transport in the body, which is why runners ask about it, but supplementing without knowing your levels is guesswork. Testing first is cheaper than a year of the wrong dose.
Frequently asked questions
Three groups, with different jobs. First, fuel you take during exercise: carbohydrate drink mixes, gels, chews and bars. Second, hydration products: electrolyte tablets and powders that replace sodium and other salts lost in sweat. Third, daily nutrients that support a heavy training load, such as iron, magnesium, omega-3 and protein.
The first two work within the session. The third works over weeks, and only helps if your intake was short to begin with.
