Water Isn't Enough.
You Already Know That.
Plain water replaces volume. It doesn't replace what you lose.
Sodium. Potassium. Magnesium. These aren't optional extras. They're the electrical system that runs your cells. Without them in balance, your hydration stalls. Energy dips. Focus fades. Recovery slows.

What 90 Days Of Proper Hydration Actually Looks Like.
DAY 1–30:
Your body recalibrates.
Morning fogginess lifts. Energy stops dipping by 3pm. You feel the difference, even if you can't fully explain it yet.
DAY 31–60:
The habit is forming.
Sachets become part of your routine. Training sessions feel more consistent. Recovery feels quicker. Your output reflects it.
DAY 61–90:
This is the baseline shift.
Proper cellular hydration is no longer a nice-to-have. It's the foundation. And you're not going back.

Frequently Asked Questions
You can. But most people who stick with Core 500 for a full 90 days tell us they wish they'd committed from day one. Real hydration benefits compound over time. One box gets you started. Three boxes is where the habit actually forms. The 3-box option is simply the smarter starting point.
No. The tiered discount applies to both one-time and subscribe purchases. If you subscribe, you get automatic re-delivery. Skip, pause, or cancel any time. The price is exactly the same either way. Subscribing is purely about convenience.
Core 500 uses Marine Magnesium (Aquamin), a premium bioavailable source not found in most electrolyte products. We're zero sugar, zero carbs, and precisely dosed for daily use, not just extreme athletes. Most other electrolyte products sit at 1,000mg+ sodium per serving, which is too much for everyday training. We sit at 500mg. The right dose, every day.
Your Cadence Cap and Digital Fuel Guide arrive with your very first order. The Core 550 Bottle follows with Month 2. Your Sports Towel arrives with Month 3. Nothing is delayed or sent separately within each month.
Mix one sachet with 500ml to 1L of still water and drink it. Use it first thing in the morning, 30 minutes before training, during a session, or immediately after. Most people start with one sachet in the morning and add a second around training.
Yes. Core 500 contains 20mg of Magnesium per sachet - a low, daily-use dose. You can safely take two sachets a day without exceeding recommended intake levels. Many athletes use one in the morning and one around training.
Yes. Core 500 contains zero carbs and zero sugar. It's fully keto-compatible and fits any low-carb or fasted protocol. Electrolyte balance becomes especially important on keto, as reduced carbohydrate intake causes your body to excrete more sodium and potassium.
Yes. Core 500 is fully vegan. Every ingredient, including the Marine Magnesium (Aquamin), is plant-derived and free from any animal products. Also free from artificial sweeteners, artificial colours, and unnecessary fillers.
Yes. Core 500 is Cologne List® approved. Every batch is independently tested for substances banned in sport. Cologne List® is the most stringent third-party supplement testing standard used by elite and professional athletes worldwide.
Because it's not built around sugar and artificial flavouring. Core 500 has a clean, light taste by design. We removed the sugar and let the electrolytes do their job. The result is a drink that's easy to consume consistently, all day, without flavour fatigue.
Full cellular rehydration occurs within 30 minutes of consuming a sachet with sufficient fluid. Most people notice the difference in morning energy and afternoon focus within the first few days of consistent use. Bigger shifts in training output and recovery tend to show up in weeks 2 to 4.
Core 500 is made in the UK. Every batch is manufactured to the highest production standards and undergoes independent third-party testing via the Cologne List® programme before it reaches you.
What Happens When People Actually Stick With It.
I get everything I need with the hydration bundle. I have now used the products for 3 weeks and have noticed the effects in my training and games. This system has helped a ton and led me to two PRs as an added effect.

500mg of sodium is what I need to kick-start my day. When I was taking another electrolyte brand, I would get headaches from the high dose. Cadence is the right dose for me. Great taste too. Will be a recurring customer.

I drink the Core every morning before I even touch my coffee. Training for Boston and trying to find something that covers all aspects of my training, and Cadence does. The recovery is brilliant. Genuine game change after 6 weeks.
