Global opinion about PFAH
Precision Fuel & Hydration delivers exactly what endurance athletes need: clear, easy-to-digest fueling and customizable hydration options. I really appreciate the transparency in their carb and electrolyte labeling, and the products are gentle on the stomach even during long sessions. The mild flavors work well when you’re training for hours, and the variety of gels, chews, and drink mixes makes it easy to tailor your plan. Overall, a reliable, well-designed system for anyone serious about perf...

PH500
I have heart rhythm issues if not properly hydrated, but I've found PH500 deals with this issue for me, and its not too sweet, not artificial and has a mild pleasant taste.

Great products, great company!
I've been using PH for well over a year now and the products have really been a game-changer for my daily life as well as my training and races. The electrolytes taste great - not too sweet but enjoyable to drink - and I start my day with these every morning. The best thing I can say is that when I run out I'm bitterly disappointed, so discovering the subscription has been a life-saver. The delivery is quick and the personal hand-written note is a lovely touch every time you get your delivery.

Worth trying
Online assessment tool was interesting - starter pack with items gave a little overview of what's available. Not sure that I agree with the PH1500 that was advised with the assessment - tried it and it was too strong for my tastes. I'm not likely to do a proper sweat test, so I that might be a factor.
PH product flavors are lightly citrus - quite palatable.
PF gels are quite neutral in flavor and an okay texture; very easy to open and consume.
I really like the portions (30g carbs, and sodium in...

Nice product to use
Nice products to use no unpleasant aftertaste I’ve been going to cardio rehab after my triple bypass surgery and sweating a lot as it’s been hard work and these hydration products have been easy to use and have kept me hydrated throughout my rehab workouts I’m looking forward to using them when I start cycling again

Great Product - Great Company
Since beginning my foray into ultramarathoning, I have been searching for a solution that isn’t completely bland, over flavoured or thick. I was recommended your products by a friend after trying a few other brands and have found a product that works for me.
The fueling plan, hydration and carb products have been easy on the stomach to keep using them on the move.
It’s a long story but I’m training for an ultramarathon to raise money for a charity in my son’s name. The Precision products have ...
