If you ride long and often, the supplements worth paying for are carbohydrate, sodium, and possibly caffeine and iron – in that order of importance. Everything else on a typical “cycling stack” shelf is either a minor convenience or a waste of money, and a lot of it is marketed far harder than the evidence supports.
Carbohydrate and fuelling on long rides
For rides under about 60-90 minutes, water is usually enough. Past that, running low on carbohydrate is the single biggest reason riders fade, bonk, or can’t hold power in the final hour. This is the one area of cycling nutrition with genuinely strong evidence: endurance athletes doing multi-hour efforts benefit from taking in carbohydrate during the ride, not just before it.
- Gels, chews, and sports drinks all work – the format matters less than getting a steady intake in, typically building up toward 60-90g of carbohydrate per hour on rides over 2-3 hours.
- Mixing carbohydrate sources (glucose plus fructose) can help riders tolerate higher intakes without stomach trouble on very long days.
- Practise your fuelling in training. Race day is the wrong time to find out a gel upsets your stomach.
Electrolytes and sodium in the heat
This one matters more in Malta and Cyprus than almost anywhere else in Europe. Summer road rides regularly happen in 30C-plus heat, and sweat losses – and sodium losses with them – climb fast. Carbohydrate-electrolyte drinks are one of the few sports supplement categories with an EU-authorised health claim: they are recognised to contribute to the maintenance of endurance performance during prolonged endurance exercise, and to enhance the absorption of water during physical exercise.
- Sodium is the electrolyte that actually matters most for sweat replacement – potassium and magnesium play smaller supporting roles.
- Heavy, salty sweaters (you’ll know from white salt marks on kit) generally need more sodium per bottle than average.
- Magnesium contributes to normal muscle function, which is why it’s often included in electrolyte mixes, though most riders get enough from food.
- Plain water plus a pinch of salt works almost as well as a branded product for most rides under 2-3 hours.
Caffeine for endurance
Caffeine is one of the best-studied performance supplements in sport, and research consistently associates caffeine with improved endurance performance, typically at doses around 3mg per kg of body weight taken 30-60 minutes before a hard effort. It’s cheap, it works for most people, and you don’t need a “pre-workout” blend to get it – a coffee or a plain caffeine tablet does the same job.
- More is not better – benefits plateau well before the doses in some “extreme” pre-workout products, and high doses just add jitteriness and gut upset.
- Regular coffee drinkers still get a benefit, though the effect may be slightly smaller than in people who rarely use caffeine.
- Test your dose and timing in training, not on event day.
Protein for recovery
Cyclists often under-rate protein compared to runners or lifters, but it matters for recovery between hard training days and for maintaining muscle through high-volume blocks. Protein contributes to the maintenance of muscle mass, and most active cyclists do well aiming for roughly 1.2-1.8g per kg of bodyweight per day from food first, with a shake as a convenient top-up around long rides or double days.
- Whey or a plant blend both work – see our whey protein guide if you want the specifics.
- Timing within a day or two matters more than hitting a shake within some exact “anabolic window.”
Iron, especially for women and high-volume riders
Iron deficiency is common in endurance athletes, and especially in women who menstruate and in riders piling on high weekly volume, because both foot-strike-style impact (less relevant to cycling) and general endurance training increase iron turnover. Iron contributes to normal oxygen transport in the body and to the reduction of tiredness and fatigue – which matters directly for anyone whose sport is aerobic capacity.
- Don’t supplement iron on a guess – get ferritin checked by a GP first. Too much iron isn’t harmless.
- Unexplained flat legs, poor recovery, or persistent fatigue despite adequate sleep and fuelling are worth a blood test, not a bottle off a shelf.
- See our iron for athletes guide for more detail.
Vitamin D
Indoor trainer season, early or late rides, and generally covering up in kit all cut sun exposure, and vitamin D deficiency is common even in sunny countries. Vitamin D contributes to the maintenance of normal muscle function, which matters for anyone producing repeated power efforts over a long ride. A blood test is the only way to know if you’re actually low – see our vitamin D for athletes guide.
What’s oversold on the cycling supplement shelf
A lot of “cycling-specific” products are ordinary ingredients repackaged with a bike on the label and a bigger price tag.
- Beetroot/nitrate shots have some evidence for a small performance bump in trained athletes, but the effect is modest and inconsistent – not the guaranteed watts boost the marketing implies.
- BCAAs sold separately from protein add little if you’re already eating enough total protein – most riders are better off just hitting their protein target.
- “Fat burner” and thermogenic blends marketed at cyclists trying to lose weight for climbing rarely outperform caffeine alone, and often just repackage caffeine at a premium.
- Branded electrolyte tablets at a big markup over a basic sports drink mix rarely offer anything meaningfully different in the ingredient list.
Building a simple, honest stack
For most cyclists doing regular long rides, a sensible starting point is: carbohydrate during rides over 60-90 minutes, an electrolyte drink or added salt in hot weather, caffeine before hard efforts if you tolerate it, a protein top-up on heavy training days, and a blood test rather than a guess for iron and vitamin D. CapyFuel ships protein, electrolytes, and caffeine products across Malta and Cyprus, so building that stack locally doesn’t mean waiting weeks for a delivery from abroad.

Frequently asked questions
What supplements do cyclists actually need on long rides?
Carbohydrate during rides over 60-90 minutes and sodium in hot weather matter most. Carbohydrate-electrolyte drinks are recognised in the EU to contribute to the maintenance of endurance performance during prolonged endurance exercise and to enhance the absorption of water during physical exercise. Caffeine, protein for recovery, and iron if you're deficient come next.
Does caffeine actually help cycling performance?
Research consistently associates caffeine with improved endurance performance, typically at around 3mg per kg of bodyweight taken 30-60 minutes before a hard effort. It's one of the better-supported supplements in endurance sport, but more is not better - benefits plateau well before the doses used in some pre-workout blends.
How much sodium do cyclists need in hot climates like Malta or Cyprus?
It varies a lot by how much you sweat and how salty that sweat is, but heavy or visibly salty sweaters generally need more sodium per bottle than average riders. A carbohydrate-electrolyte drink or plain water with added salt both help maintain performance and hydration on hot rides.
Should cyclists take iron supplements?
Only after a blood test confirms low ferritin. Iron contributes to normal oxygen transport in the body and to the reduction of tiredness and fatigue, which is relevant for endurance athletes, but iron deficiency should be confirmed by a GP before supplementing - excess iron isn't harmless.
Are beetroot shots and BCAAs worth it for cyclists?
Beetroot/nitrate shots have some evidence of a small, inconsistent performance effect in trained athletes but are not a guaranteed power boost. BCAAs taken separately from protein add little if you're already meeting your daily protein target through food or a shake.
