Start here if you're new to all this. If you've never used electrolytes, or you're not sure which formula you'd actually reach for, this is where to start.
You don't have to guess. Most people already know they feel flat, foggy in the afternoon, or wrecked after a hard session.
What they don't know is that the fix is usually the same thing: they're losing more than water and putting back too little. The three formulas each handle a different part of that.
This gives you ten of each, so you can feel where they fit before you commit to a full pack of one. The lowest-risk way to find out what Cadence does for you.
The Cadence Sachet Stack is the complete hydration package. With 30 total sachets, it includes all three of our Hydration Sachet options.
Core Hydration
Core 500 Sachets deliver a science-backed ratio of electrolytes, namely sodium, potassium and magnesium to help you maintain cellular hydration and electrolyte balance.
They feature our research-based ratio of Sodium, Potassium & Marine Magnesium, the perfect hydration solution to be used at any time of the day.
Energy Hydration
Energy Hydration Sachets are a potent electrolyte and energy blend, with Sodium, Potassium and Marine Magnesium.
The Sachets deliver an evidence based 2:1 ratio of L-Theanine and Caffeine. Studies show that this specific combination of L-Theanine and Caffeine can provide optimal mental and physical benefits, including improved mood, clarity of thought, reaction times, alertness, memory and learning, whilst also offsetting many of the negative side effects often associated with caffeine consumption.
Sleep Hydration
Sleep Hydration Sachets offer a lower dose of electrolytes to help you retain more fluid overnight, thus reducing disturbed sleep from waking and promoting better restoration and regeneration.
The Cadence Sleep Formula is a potent formulation with active ingredients proven to help you unwind, fall asleep faster, and experience a longer, deeper, and more regenerative sleep. The Sleep Complex includes L-Tryptophan, L-Glycine, L-Theanine, Ashwagandha, Valerian Root Extract 10:1, Vitamin B6, Zinc, and a higher dose of Magnesium.

One system, three formulas.
Hydration doesn't clock off Most people cover one part of the day and leave the rest. This covers all of it.
Daily keeps you topped up, Energy lifts the flat spots, Sleep works while you recover.
Ten servings each, so you can find where they fit.
A hard, hot or busy hour drains 500 to 700mg of sodium. Most drinks give you 200 to 300. Cadence closes the gap, dosed with sports nutritionist Matt Jones to what you actually lose. Zero sugar, third-party tested.

"This was gifted to me and I've really been enjoying the Variety Pack. The Core is perfect for daily hydration, and the Night formula has been great for winding down in the evening. I can feel the benefits - more hydrated and less tired. Love having all three formulas in one stack!"
"I really like the Hydration Sachet Variety Pack. It’s great having different options for different times of the day, and the sachets are really convenient and easy to use. They taste great, mix easily and are a handy way to stay hydrated, especially when you’re busy or active. I’ve really enjoyed trying the different formulas and would definitely recommend the variety pack. ⭐⭐⭐⭐⭐"
"Really pleased with this product. Since I started using it after hockey and padel, I've felt noticeably more hydrated and far less tired afterwards. Recovery seems quicker, and I don't get that sluggish, drained feeling I used to. It's now a regular part of my match routine."
"A friend recommended this to me as I really struggle to sleep and struggle to stay energised throughout the day. This has honestly surpassed my expectations; the energy sachets are perfect before a long run or heavy gym session, the sleep sachets help me unwind, fall asleep, but also do not leave me groggy in the morning!"
"Great product got this to try all 3 and have noticed the benefits for all my sessions and workouts, the energy one gives you a nice little boost in the afternoon as an alternative to coffee. All taste great worth the investment and fantastic quality."
"Good taste. Great to have different type to suit time of the day and type of workout."
"Great for each part of your day, regular hydration, afternoon pick me up and calming down at the end of the day prepping for your next big workout."
"Really helps me sleep without the usual glass of wine"
"So handy to have in your gym bag and for on the go and the flavours are unreal"
"Items was great loves the mealtime one to help sleep carry the hydration pack with me at work will end up getting more"
