Great product and excellent customer service
I have found these electrolyte tabs to be excellent. They dissolve quickly and easily, leaving a pleasant lightly flavoured drink that really quenches the thirst. They also mix well with an energy powder of your choice. Would highly recommend them, particularly as they come in a variety of dosages.
On top of this, the service I have received from Precision Fuel & Hydration has been absolutely superb. From the speedy delivery, insightful articles and advice, to the follow up on purchases. Will ...

Fab products!
I’ve know used precision products to fuel me for 2 half marathons and my training leading up to them. I love them. I’d never use any other brands because the service is always efficient and friendly. I’ve recommended them to so many people.

Great product
Great product, nice taste! A lot of packaging options, which is convenient. Chews are my favorite among all available non gels options on the market!

Great stuff
These are the best fuel and Hydration products I have ever used in 20 years of long distance (amateur) running.
I was particularly impressed by the flavours of the gels, PH500 tabs and the fab little chew bar. It’s like eating a Turkish delight on your run! I often find sports drinks taste pretty bad well into a run but PF&H have solved this problem.
Personally I like the gels and bars more than the carb drink. I tend to drink to thirst when running so I find it easier to get the right amount ...

I changed to Precision as the reviews were great and the products are amazing. I’ve already PR’d on my training run and am confident for my race. I love the emails with advice and the ability to book a review with coaches when needed. It really is a superior product and fabulous service all around
