Our award-winning Chia Energy Gel, now in a multiserve refill pack with soft flask. 

While most gels are ultraprocessed (UPF) formulas, Chia Energy Gel is different - all-natural and UPF-free, use whether you're racing, hitting a big session or building easy base. Trusted in the world's toughest races, this is energy you can enjoy. Multiserve is the same gel you already know, in one 15-serving pouch.

Prep is fast and easy. Scoop up to three gel servings into your 33Fuel Chia Flask, then add water (the classic), fruit juice (for flavour and a carb boost), coconut water (electrolyte boost), or fresh coffee (best ever caffeine gel). Shake, leave 10 minutes and go. Prep before your session or race then use like any other gel - once prepped gels last 24 hours.

  • 15 servings per pouch, 3 per flask
  • Requires the 33Fuel Chia Flask - ordinary soft flasks clog
  • Natural Hydrogel
  • No energy spikes or crashes, just strong stable energy
  • Food, not a formula

Daily training. Big race.

The UPF-free gel you can use for racing AND training.

Being little more than liquidised UPF, ordinary gels can feel like emergency fuel - more of a race day neccessity than a sound life choice.

Chia Energy Gel is different. Four real-food ingredients, stable energy, no stomach trouble and zero UPF. Proven on race day, clean enough to use every day.

Train with it

Real-food energy for everday sessions.

Race with it

Fuel serious efforts when your gut has no patience for nonsense.

Trust it

Just chia, coconut sugar, vanilla and salt. Natural, simple and powerful

33Fuel Chia Energy Gel ingredients: chia, coconut sugar, vanilla and salt

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.

Chia Energy Gel Multiserve FAQs.

Fifteen. Each serving is 21g - two tablespoons - exactly the same as one Chia Energy Gel. Three servings fill a flask, so one multiserve refill pack= five full flasks.

Yes and it's the one thing to get right on your first order.

Chia seeds are too big to pass through a standard soft flask nozzle. They block it.

We designed the 33Fuel Chia Flask with a wider flow nozzle so the gel comes through perfecly. It's the only flask we know of that will work with this product.

If you're new to Multiserve, choose the Starter Kit and you'll get both. You'll also make a huge saving on the flask..

✅ Add up to three servings (two tablespoons each) into your 33Fuel Chia Flask
✅ Fill with your liquid of choice
✅ Seal and shake
✅ Leave 10 minutes - the chia forms a natural hydrogel

That's it. Prepped gel keeps for 24 hours, so you can do it anytime before your race or session, then just use like any other gel.

Up to three (63g of product). That gives you 300 calories with natural electrolytes and 7g of protein in a single flask. Plenty for most long sessions. One or two servings works just as well for shorter efforts.

You have exacly the same super-flexible options as with the single-serve Chia Energy Gels, which are:

✅ Water - the classic, light vanilla taste
✅ Fruit juice - more flavour, more carbs
✅ Coconut water - added natural electrolytes
✅ Fresh coffee - the best caffeine gel you'll ever have!

Identical. Same four natural ingredients, same nutrition, same zero UPF, same everything: chia seeds, organic coconut sugar, pure vanilla and Himalayan pink salt.

The only difference is the format: one 15-serving pouch instead of individual sachets.

Just four natural real food ingredients:

• Chia seeds
• Organic coconut sugar
• Pure vanilla
• Himalayan pink salt

No artificial anything. No emulsifiers. No unpronounceable chemicals. No UPFs.

Yes. Take the refill pack, or pre-measure servings into a small bag, and top up your flask at an aid station or halfway point. Alternatively buy extra flasks to carry multiple ready-made fueling packs

Yes – and this is a major difference. Most energy gels are ultra-processed (UPF) gut bombs.

Ours are real food and are safe to use daily without trashing your digestion or wellbeing.

Our Chia Energy Gels delivers stable sustained energy without spikes or crashes.

Each gel is also contains 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.

24 hours - so prepare it in advance of your session or race, then simply 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 to ordinary gels

• Ordinary gels = UPF gut bombs
• Chia Energy Gels = nutrient-dense, clean fuel

These don't just deliver performance - they're gut friendly, naturally contain heart healthy Omega-3s, and deliver protein microdoses to support sustained effort.

That’s the power of natural sports nutrition done right.

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.

Many users also say they enjoy their training and racing more when they fuel with Chia Energy Gel - when your stomach's not in knots and your energy's not endlessly spiking and crashing, the mental game gets a little easier, giving you more opportunity to enjoy the moment.
