Energy Gel 33Fuel

Use Chia Energy Gel for tasty satisfying fuel during exercise. Natural hydrogel energy gels you can enjoy these are as happy fueling your weekend run or daily gym workout as they are powering the toughest endurance sessions

How to use
We said these gels pack a BIG surprise for new users and here it is: all Chia Energy Gels are supplied dry and you prepare them before use.

This is easy and quick and as all Chia Energy Gels last for 24 hours once prepared you can prepare them before your sport and then use like any other energy gel.

  • Open the cap & inflate the pack by blowing into it,
  • Add water until pack is full 
  • Close, shake well to blend the natural energy gel
  • Leave for 10 minutes as the chia naturally forms a hydrogel
  • Your Chia Energy Gel is now ready - enjoy!

When to use
Use Chia Energy Gels during sport or training to keep energy levels strong throughout. Consume one gel every 45-60 minutes during exercise

Pro tip

  • Change flavour with your favourite fruit juice instead of water, use coconut water for added electrolytes or use fresh coffee for the most incredible caffeine gel you've ever had!

Good to know

  • Vegan, plant-based and delicious
  • High in heart healthy Omega-3 fatty acids
  • Strong and stable energy
  • No stomach trouble

Our Chia Energy Gel, like all 33Fuel products, follows our unique Plant-Based & Planet-Based® approach because plant-based and vegan formulas aren’t just better for performance and health, they’re also better for the planet than animal-based formulas.

Every Chia Energy Gel also:
• Has fully recyclable packaging with the exception of the caps (and we are working on these!)
• Has a flip-top cap - no more accidental tear-top littering
• Is uniquely supplied dry to avoid shipping unnecessary water & weight reducing emissions and also reducing pressure on water systems as no water is tied up in the gel's lifecycle. You simply hydrate them before use (once prepared they last 24 hours so you can do this well in advance)
• Is delivered packed in plain, recyclable delivery packaging
• Is available with free carbon neutral delivery
• Helps reforestation. A portion of all 33Fuel sales go to One Tree Planted to help fund their reforestation efforts around the world

We’ve been crafting award-winning vegan sports nutrition at 33Fuel since 2012 and everything we do is lead by our Fuelosophy® for Performance, Health and a Fitter Future.

All 33Fuel products live this Fuelosophy so you can always buy Chia Energy Gels with confidence knowing they will fuel your performance today, your health tomorrow and help build a fitter future for you and the planet

Very good, but bulky, but never have any guy issues and when empty can be used as a water carrier for the next run
