Cycling is an endurance game with sharp edges: long steady hours broken up by climbs, sprints and the odd all-out effort. That means your supplements should lean toward hydration and fuel first, with a bit of strength and recovery support on top. Here is a practical stack built for how riders actually train and race.
The short answer
- Electrolytes: the first priority for long, sweaty rides.
- Intra-workout: EAAs and fuel to sip through rides over an hour.
- Protein: for recovery between sessions.
- Creatine: helps with sprints, attacks and steep climbs.
- Magnesium: to support recovery and sleep after big days.
If you only add two things, make them electrolytes and an intra-workout. They change how a long ride feels more than anything else on this list.
Electrolytes: replace what you sweat out
Time in the saddle plus heat equals a lot of lost fluid and sodium. That loss is what leaves you flat and cramp-prone in the back half of a ride. An electrolyte mix helps you hold hydration far better than water alone, which keeps your power and focus steadier.
Pillar Electrolyte Hydration Sticks drop straight into a bottle and are easy to carry. Ghost Hydration is a tub option with plenty of serves. Have a look at the full electrolytes collection to pick a flavour you will actually drink.
Intra-workout: fuel the long rides
On rides over an hour, sipping an intra-workout with EAAs helps you keep going and supports recovery once you are off the bike. It works alongside your normal on-bike food rather than replacing it, and it is a genuine difference-maker on the big weekend days.
Ghost Intra mixes light and easy in a bottle. Raw Nutrition EAA is a clean full-spectrum amino option. Both live in the EAA and intra-workout collection.
Protein: recover between rides
Endurance training still breaks down muscle, and if you are riding often, recovery is what lets you back up day after day. Hitting a solid daily protein target is the base of that, and a shake makes it easy when you finish a ride hungry but not ready for a full meal.
Ghost Whey is a reliable everyday whey. If you want something lighter and refreshing after a hot ride, Nexus Super Protein is a clear, sparkling collagen protein water. Compare in the protein collection.
Creatine: for the sharp efforts
Here is the honest bit. Creatine helps most with short, hard efforts: sprints, attacks and steep climbs. So if you race crits or the track, it is well worth it. If you only ride long and steady, the benefit is smaller and some riders skip it to avoid the small water-weight gain. Decide based on your riding.
EHPlabs Crea-8 is a simple 5g monohydrate if you want it in. See the creatine collection for other formats.
Magnesium: recovery and sleep
After big days, magnesium supports normal muscle function and recovery, and a lot of riders take it in the evening to help wind down and sleep. It is not an instant cramp fix, but good sleep is a huge part of endurance recovery.
Pillar Triple Magnesium Powder is an easy nightly drink. Browse the magnesium collection for capsule options too.
A sample ride day
| Time | What to take |
|---|---|
| Before a big ride | Electrolytes in your bottle |
| During rides over an hour | Intra-workout and electrolytes |
| Within 1 to 2 hours post | Protein shake |
| Daily | Creatine 5g (if you sprint or climb hard) |

Keep it simple: hydrate and fuel on the bike, recover with protein and magnesium off it.

FAQ
What supplements should cyclists take? For most riders the priorities are electrolytes to replace what you sweat out, an intra-workout to fuel longer rides, and protein to recover. Creatine helps with sprints and hill efforts, and magnesium can support recovery and sleep. Start with hydration and fuel, since those affect how a ride actually feels.
Do I need electrolytes for cycling? If your rides run long or you sweat heavily, yes. You lose sodium and fluid on the bike, and replacing them helps you avoid cramping and the flat feeling late in a ride. For short, easy spins, water is usually enough.
Is creatine worth it for cyclists? It depends on your riding. Creatine helps most with short, hard efforts like sprints, attacks and steep climbs, so track and criterium riders get the most from it. For pure long-distance endurance the benefit is smaller, and some riders prefer to skip the small water-weight gain.
What should I take during a long ride? An intra-workout with EAAs, plus electrolytes, helps you keep fuelling and stay hydrated on rides over an hour. It supports your muscles through the effort and helps recovery afterwards. Pair it with your usual on-bike food for longer days.
Can magnesium help with cycling cramps? Magnesium supports normal muscle function and recovery, and many riders take it in the evening to help with sleep. It is not an instant cramp cure, since on-bike cramp is usually about hydration and fatigue. Think of it as a recovery and sleep support rather than a quick fix.
