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.

Game Changer
I have been using Precision Hydration product for just over a year now and it really has become a game changer for me in all aspects training racing and recovery ,the guys at PH are great .It’s not just a product it’s like having a trainer that helps you get the best out of yourself , always there to answer any questions and have updates on how the Pros do it

So far so good
I'm still experimenting with these products but so far have found them to help keep me feeling hydrated on my runs.

So far so good!
I’ve always struggled with maintaining proper hydration. I’d end up with leg cramps and bad headaches as a result. I started looking at electrolyte supplements but many contained artificial sweetener that triggered my migraines. I’m on my second box of precision hydration and so far I’m really liking it! I start my morning off drinking half of a packet and it seems to really help me maintain regular hydration throughout the day. Once it warms up outside and I start running again, I’ll move up to a full packet a day. The taste isn’t offensive. I don’t tend to like citrus flavors, but this one is mild enough that I don’t mind it at all. Really happy with my purchases so far! Shipping has been lighting fast, which is a rarity these days.

Helped switch my focus from nutrition to hydration
Doing shorter running and cycling events, and always vaguely aware of being a sweatier-than-average-athlete, the online questionnaire + Andy Blow on a Trainerroad podcast + product has made a difference to both my training (particularly hot and sweaty turbo trainer sessions) and races. Early days, but better pre-hydration seems to make more of a difference to me than post-nutrition. Good website and reliable deliveries and follow-up emails, too.

Ironman Game Changer!
3 years ago I had the opportunity to have a sweat test done with Pro Ironman Brooke Brown in my home town, Windsor Ontario. The sweat test solidified my racing needs, and I began using PH 500 to support my long rides and intensity workouts with amazing success! I was able to mentally focus and perform and recover faster due to the electrolytes tailored to my needs! A podium finish in IM Arizona 2018 was assisted with the right hydration! Keeping my hydration delegate from my glucose allows me to tailor my needs around race day without abdominal discomfort o which is so frequently felt when consuming the wrong ratios. My power output is stronger and more consistent with PH. Hydration matters and each person is different, I do not require a high sodium electrolyte replacement and it was difficult to know what my body needed, the sweat test clarified my needs and then I began training harder and faster with the proper hydration ratios! Thanks guys for making this product! You have totally changed my race!

Game changer for me.
I approach all these things with a healthy level of skepticism but buy does this stuff make a difference to me. I'm now riding with just the one bottle - no more chugging constantly from a hydration pack feeling constantly parched. I load upfront with a 1500 on my way to the ride (usually consumed during a 1-2hr drive), then have a 500 in my bike bottle and I'm golden. Feel so much better during and after the ride. No more horrendous gas or burping either like other hydration supplements. Found via the Downtime Podcast, so mega props for supporting that chap!

Great training aid
I have been using PH1500 and 500 for a month or so and have found it to be a great hydration product before and during training. will definitely be my choice when competing this year.

Great Product
I recently switched to Precision Hydration from another product due to GI issues. I have found PH to be easy on the stomach and the light citrus flavor is easy to drink during extended bike rides. The electrolytes also provide enough energy for the shorter medium intensity rides. I use PH as prescribed after completing the recommended sweat test and am very glad I did it.

Perfect drink for long races
My husband and I discovered this drink on the Otillo world swimrun series. We were first surprised by the taste because it is not very sweet. It's a little bit like highly mineralized water so it is not sickening after hours of racing. It allows drinking more and eating too. I really like the tablets because your drink is a little bit sparkling.
