I’ve been searching for the perfect electrolyte brand for a while, but most options haven’t hit the mark—either they’re too sweet, too salty, or just hard to consume daily without becoming sickening.... See more

A life saver!

My husband has Motor Neurone Disease and his thermo-regulation system doesn't work so he can't control his temperature. We need to rehydrate him and this is the only product that he likes. It is great that I don't have to worry about it arriving. All in all, a win-win situation.

One of a kind!

I typically hate electrolytes, I gave these guys a go on a whim after someone said they tried them. And oh my goodness me, these are incredible!! Tasty. Not too salty. Not too sweet. Refreshing. I will never look back! Thankyou Proof! Peach flavour is my favorite so far!

Can’t live without it

Can’t live without it! It changed my life and it’s the first thing I drink in the morning before my coffee. I work in such a fast paced environment so helps me focus so much.

The best electrolytes you need

I was looking for a long time to find great electrolytes that aren’t packed up with sugar or nasties something that goes with my values to be super clean and hydrating until I find proof and it’s been an amazing change as most of the time I am dehydrated or super exhausted and it’s help me to go through the day with ease

The service form Proof was excellent

The service form Proof was excellent. Delivery was on time and everything went to planned. I was recommended this product by a friend and tried to without any expectations. After a week of using the product I felt my energy levels risings and I wouldn’t get tired at my usual time in the evening. Honestly it’s a game changer even for people like myself who don’t keep fit. Will keep on using! Thanks Proof.

The perfect mix

Proof is now my favorite electrolyte mix. Not too sweet, not too salty, and has all-natural ingredients. Hard to bring myself to go back to anything that isn't Proof now.

I'm afraid I will be cancelling

I'm afraid I will be cancelling. I love the idea and would use it if it didn't have so much sweetener in it. I can't take it

Reply from Proof Hydration

Hello XYZ

Thank you for your feedback, and we are sorry to hear this.

Our formula is designed to have a subtle flavour, so we’d recommend checking if it was prepared according to the instructions (mixing with 500-700ml of water). That said, we understand preferences vary, and if the product isn’t right for you, we would be happy to process a refund.

To note, we have looked through the subscriptions and none have been cancelled over the past month, so we struggling to refund your order. Please email info@proofhydration.co.uk and we will get this sorted

I've been using Proof for 3 months now

I've been using Proof for 3 months now, and I could not recommend it enough! It not only helps me with energy and recovery on workout days, but also general focus and energy levels, brain fog, staying hydrated, and improved wellbeing, especially in the winter months or when travelling.

The best part - it tastes fantastic (My favourite is Lime!)

Best in Market - highly recommend

Could not speak more highly of this product. By far the best I’ve seen in the market. Usually try to steer clear of electrolyte supplements but Proof hydration actually does what it’s supposed to do! Highly recommend if you are into health/fitness.
