Works for me
Relatively new to PH but love it. Have tried many products over the years but for me PH gets the balance right for a product I can consistently use training, racing and recovering.

Best electrolytes I have found
The best electrolytes I have tried. The taste is great, making it easy to keep hydrated. Definitely would recommend.
Good for more than running or biking
I use the 500 tabs on days when I'm going for a 5-8 mile run, or when I'm doing heavy duty work in the garden (moving rocks, turning soil, etc...). They work well on days when I'm doing long hikes and I even took a tube along on my last Camino in Portugal. Good for staying hydrated when I'm not doing the long endurance workouts.
I’ve used PH since I organised a sweat test evening for the local Tri club over 3 years ago. I’m not a very heavy or salty sweater, however I’ve always tried to take hydration seriously for all events from sprint tris to half iron mans. I use 500 and 1000 products, both are easily to take with no salty taste. I also make sure my husband-who is a heavy sweater takes the 1000 when he trains. Since the COVID lockdown we’ve obviously been hitting the turbo a lot more, so the sweat level has increased. We use PH every time we hit the turbo and so far we’ve never had any cramps. I use PH with a mix of other products for nutrition during racing and have never had any GI issues. This is a fantastic range of products and would recommend to anyone regardless of sweat level.
Early days early improvements
Only used 1 pack so far but already find that I’m not drinking as much so stomach isn’t sloshing about like I used to with some products leaving me thirsty and bloated! Flavour is not too strong which helps you want to drink to thirst as recommended
Great Hydration Strategy
I heard about Precision Hydration during a podcast with Trainerroad and they rated it very highly. I started with the starter pack after i took the online sweat test, used the products and loved them. I then re-ordered more of the 500 PH and also the 1500 PH. I've been using them whilst cycling indoor after recovery from a broken arm and operation for a plate. When i use the products as required before, during and after the rides i find that i can get through them and recover better than without them. I'm just about to re-order as i'm nearly out. Looking forward to improving on the bike with structured training and also a structured hydration plan.
I use these all the time when running obstacle course races competitively. Since using these I have not cramped at all and can’t recommend them highly enough
Wouldn't consider endurance events without them
I know if you are serious and regular athlete then your muscles don't need help to overcome hydration and cramp. Well I'm a happy and regular cyclist (in the summer months) who likes endurance events, often spending 4+hours in the saddle and without help, I do suffer from both cramp and de-hydration. Introduced to me by a fitness trainer a couple of years ago, since I started taking pro-hydrate every day (250's) and 500's for the longer distance rides and they have made a huge difference to my enjoyment of my activities. I wouldn't consider doing these types of events without them.
For the whole family
I use this to hydrate on a daily basis as well as to be able to sustain gym classes. Lemon is my go to flavour, but we have the whole range in our house. My husband is the cyclist and goes for a higher hydration level but we also recently bought 250 for our son who like me finds water and hydration difficult. Perfect for everyone’s needs.
Good in 40 degree heat on the bike!
Once again I've been off on tour, complete with panniers and clarinet - bike at 30kg... This time the Pyrenees, including Tourmalet, Peyresourde, Aubisque etc.. 10 days, 836km and 14612m, some of it in 40 degree heat. With 1500 PH am and pm, and 500s on the bike, not only did I not dehydrate, but I also didn't get cramp. This stuff is quite simply the best! I pair it with pain au Raison and large espresso - probably even better with proper fuel. So a massive thank you guys..
