Customizable alternative to Maurten

Like: can mix with coffee or any other drink, not sweet, feels less artificial
Don't like: can't keep already prepared left overs, feels like a lot of plastic (esp cap), cap of little benefit because of the small amount per gel, cap make it hard to really get every last bit out, extra costs for people outside of UK (had to pay €20 customs fee for €85 order) making it more expensive than 'the golden standard' Maurten for me

Hi Douwe,

Thanks for your review of our Chia Energy Gels - I'm pleased to hear you enjoy the taste and natural ingredients. Appreciate your input on Shipping costs, it's something we're working hard to manage to ensure our International customers are able to get the best value for money.

Kind regards,

James
Team 33Fuel

Feel good with a great taste!

I've been really impressed with Ultimate Daily Greens. Very easy to work into a daily routine and I am feeling the physical benefits - more focus and energy. The most surprising thing has been the taste - it's actually very pleasant! I hadn't expected to actually enjoy this part but pleasantly surprised. Would recommend to anyone.

Hey Mark,

Thanks for taking the time to leave a review for our Ultimate Daily Greens, and I'm thrilled to hear you're feeling the benefits of taking them on a regular basis (and that you're enjoying the upgraded taste!).

Look forward to serving you again soon.

Tasty Greens

Really enjoy the taste and energy hit I get from my daily 33 greens.

Hi Callum,

Thanks for taking the time to leave some feedback - we really appreciate it - and I'm delighted to hear you're loving the taste of our new Ultimate Daily Greens. We're stoked with the response to the new flavour :)

Keep rocking it, and we look forward to serving you again.

Warren,
33Fuel Co-founder

I haven’t tried it yet, it seems quite complicated compared to other Greens brands. I don’t drink pineapple juice, which is what they suggest. I won’t buy again

Hi Michael,

Thanks for leaving us a 5* review and taking the time to share your thoughts. I'd suggest, however, that our Ultimate Daily Greens aren't 'quite complicated'...all you need to do it mix the powder with water and you're good to go! You can mix it with juices and smoothies if you like, but if you want to keep it simple just chuck it in water and swig :)

Let us know if we can help further.

Protein bar

Purchased & sampled the 33 fuel protein bars , a dense bar , reminiscent of a Christmas product with nuts peel and a little spice , a nice dry texture not greasy at all but best eaten with a drink , in 2 mini bars so can be consumed at 2 different times or shared . Would recommend.
