Tarahumara-inspired
Before gels got weird, there was chia.
Legendary tribal ultrarunners the Tarahumara knew something modern sports nutrition can forget: natural fuel exists, and can be seriously effective.
Their go-to, a chia blend called iskiate, works because chia absorbs water, forming a natural hydrogel. No weird lab work needed, just real food doing the extraordinary.
Chia Energy Gel takes iskiate and tunes it up for modern athletes so you can say goodbye to energy gels that taste like poor life choices.
✓Natural Hydrogel
✓Food. Not a formula
✓Fully customisable to your taste & needs
The killer difference
One gel. Four ways to make it yours.
Chia Energy Gel starts dry and becomes whatever you need. Keep it simple with water, boost carbs with fruit juice, boost electrolytes with coconut water, or add fresh coffee for a pure caffeine kick. Prep pre-session or race, then use like any other gel - once prepped gels last 24 hours.

Each gel is shipped dry to save emissions and avoid unnecessary water weight. To prep:

4. That’s it – the chia forms a gel naturally.
Once prepared your gel lasts 24 hours, so prepare in advance of your race or session, then use just like any other gel.
Take a look at the 'How to use' section of this page for more information.
Great question – and great news for the planet. Dry shipping:
✅ Lets you customise your gel
✅ Cuts emissions by reducing water weight

✅ Less waste, more impact – a perfect fit for our Plant-Based & Planet-Based® Fuelosophy®.
Consume one Chia Energy Gel every 45–60 minutes during sport.
It’s ideal for runs, rides, races and gym sessions – or any time you want clean, natural energy on the go.
Great question – and here’s the short answer: our Chia Energy Gels prioritise nutrient density over empty calories.
Each gel delivers 100 nutrient packed calories with 11g of natural carbs, plus heart-healthy omega-3s, a little protein from quality ingredients. And no UPF anywhere.
Most gels cram in 20–25g of empty-calorie UPF carbs like maltodextrin. This means short-term energy spikes, followed by energy crashes and gut trouble.
Ours are different – made with quality real food for stable energy, better digestion and long-lasting performance.
Thousands of athletes around the world have made the switch – including a sub-3-hour marathoner who went from 3 gels per hour to just two of ours over the entire race, with no performance loss and far better gut health.
It’s a leap to try these for the first time but we promise its one you won’t regret.
This is one of our favourite features because depending on what liquid you add to the gel you can adapt the flavour to suit your needs
✅ Water = a light vanilla taste
✅ Juice = a fruity boost with more carbs
✅ Coconut water = new taste and added electrolytes
✅ Coffee = the ultimate DIY caffeine gel
You’re in control. One gel is now every gel you ever wanted!
Just four natural real food ingredients and that's it:
• Chia seeds
• Organic coconut sugar
• Pure vanilla
• Himalayan pink salt
No artificial anything. No emulsifiers. No unpronounceable chemicals. No UPFs.
Yes. 100%. The Chia Energy Gel is:
✅ Vegan
✅ Gluten-free
✅ Dairy-free
✅ Soy-free
✅ Made entirely from real food with zero UPF
Yes – and this is a major difference. Most energy gels are ultra-processed (UPF) gut bombs that should come with a health warning.
Ours are real food, so are safe to use daily without trashing your digestion or health, in fact they'll benefit both
Our Chia Energy Gels delivers stable sustained energy without spikes or crashes.
Each gel is also high in heart-healthy Omega-3 fatty acids and includes a natural electrolyte blend with Himalayan pink salt to support hydration and performance and keep your muscles firing as fatigue sets in.
Once prepared, the gel lasts for 24 hours so prepare it in advance of your activity then carry with you and use like any other gel
Nope. These are famously gut-friendly.
Because we use only real food and zero artificial additives with no UPF, you avoid the cramps, bloating and toilet dashes common with ordinary gels
• Ordinary gels = UPF gut bombs
• Chia Energy Gels = nutrient-dense, clean fuel
These don't just deliver performance – they add health benefits too. That’s the power of natural sports nutrition done right.
Yes, the gel comes in fully recyclable packaging with a flip-top cap so you don't have to have it all in one go and to prevent the accidental littering common to rip top gels, aligning with our commitment to a Fitter Future (all part of our Fuelosophy, which you can read about here: https://www.33fuel.com/pages/the-33fuel-fuelosophy
Unlike UPF gels that spike and crash, our Chia Energy Gels provide smooth, sustained release.
You’ll feel strong for longer – and recover better after.Definitely. Pair with the Chia Energy Gel for a hydration + energy duo, or follow your session with Premium Protein or Ultimate Daily Greens for full-body recovery and immune support.
Absolutely. From sub-3 marathoners to Olympic athletes, elite ultramarathon runners and 1000s of weekend warriors worldwide, our gels are trusted by those who think long-term.
Read the reviews - you’ll find dozens of real-world results and success stories.
Yes, and many do. But we recommend starting with one every 45–60 minutes and adjusting based on your training load and personal needs.
