If your sessions are one to two hours at an intensity that leaves you soaked, DRVN was formulated for you:
Fighters, Hyrox athletes, CrossFitters, anyone training at the top end.
Most electrolyte products are underdosed for this kind of work. They're either built for endurance runners and cyclists whose needs are different, or they are lifestyle drinks with token doses, cheap salt forms and unneeded fillers.
DRVN was designed around what you actually need: electrolytes dosed to replace what is lost in a litre of sweat, premium salt forms to soak up excessive acid and support your energy cycle, and dual-source carbs to fuel your muscles and restore glycogen stores.
If you want to push the tempo when others are fading, DRVN is for you.
1000 mg Sodium.
400 mg Potassium.
200 mg Magnesium.
30 grams Carbs.
Premium acid-binding salts.
Sessions that push your limits.
Engineered for high output athletes
Born from a passion for high-performance sport, DRVN supports you through those sessions where you are reach your limits and helps you get the maximum from them.
What our members are saying
Let customers speak for us
I have tried a variety of electrolytes from some highly recommended brands sold at the gym I work at. I can honestly say that within days of using DRVN I wont be using any others.
I am highly active coaching k1 and thai boxing and inevitably feel hydrated after a long day and had been suffering with headaches and general fatigue. Since using this formula I no longer have these problems feel much more energized and focused.

Great product, really helped with the recovery of my training, highly recommended.

I needed something to help me push my training, as I was getting tired at the end of my sessions and felt like it took a few days to recover between really hard workouts.
DRVN has really helped me be able to push harder and I get more out of my training cos I feel fresher.

Frequently asked questions
What is the DRVN founding member batch?
It's the first commercial batch of DRVN Threshold. We've been making DRVN in small custom batches for local fighters and coaches for a while now, and enough people asked where they could buy it that we decided to release it properly. The first run is 250 units, and everyone who buys from it is a founding member.
Why is the first batch discounted?
Full price is £18.95. Founding members pay £13.25 — 30% off, on this batch only.
We're confident in the formula, but we want honest feedback on flavour, mixability and packaging before we commit to a full production run. The discount is our side of that deal. You'll be emailed a short feedback form — it takes about two minutes, and what comes back shapes the full range.
Why only 250 units?
It's small enough that we can stand behind the quality of every single pouch, and small enough that we can read and respond to every piece of feedback. Once they're gone, this batch is gone.
What's actually in DRVN?
Each serving has 30g of dual-source carbs (maltodextrin + fructose), 1000mg sodium, 400mg potassium, and 200mg magnesium, plus citrate and malate salts that buffer acid build-up during hard training and support your body's energy cycle. Doses are set to match what you actually lose through sweat, not a token amount. Have a look at the formula page for more detail.
Why this amount of electrolytes?
The electrolyte doses are based on current research of average electrolyte contents in a litre of sweat, so 1 dose of DRVN replaces what the average person loses in an hour of hard training. Magnesium is a bit different, you don't lose much magnesium in sweat, but most people are slightly deficient and 200 mg is enough to help correct that on your workout days.
Why does DRVN have carbs in it?
During high-intensity training your body relies on rapid carbohydrate metabolism, not fat-burning, to sustain output. Carbs taken during exercise are used for fuel immediately rather than stored — a very different picture to carbs eaten at rest. They also help pull fluid into the body faster alongside sodium.
Will the carbs upset my stomach?
Unlikely. DRVN uses a deliberately conservative 30g carb dose, well below the 60–90g doses common in products designed for long-distance running and cycling. Higher doses like that carry a real risk of GI distress, particularly in more dynamic, high-intensity sports. The dual maltodextrin-fructose blend is also chosen specifically to reduce that risk further.
How do I use it?
Mix one scoop with 1000ml of water and drink throughout your session.
Rehydrating after a weigh-in? Don't guess it — use the Fight Week Rehydration Calculator to get a full timed drinking plan built from your own cut.
How many servings should I take per session?
Usually 1–2, depending on how long you're training, how salty a sweater you are, and your individual sweat rate. Use the Sweat Rate Calculator to work out your own number and get a session-specific recommendation.
Is DRVN good for weight cuts?
Yes — it's ideal for rehydrating after a weight cut. The sodium and carbohydrate combination pulls fluid back into the body faster than water alone, which is exactly what you need in the narrow window between weigh-in and competing. See the Fight Week Rehydration Calculator for a full timed plan based on your own cut.
Postage & delivery
Postage is calculated at checkout based on your delivery address.
Where do you deliver?
UK delivery only for now. We're a small founding batch and want to get UK fulfilment right before expanding further.
Will there be more flavours or sizes?
Fresh Citrus is the only flavour in this first batch. Feedback from founding members will shape which flavours and pack sizes make it into the full range — there are questions in the form to gauge exactly that.
What happens after the 250 units sell out?
This batch won't be restocked at this price. Founding members will get a lifelong 5% discount as a thank you. Sign up to our email list on the Founding Members page to hear when the full range launches.
What's the shelf life?
12 months unopened and sealed.
How should I store it?
Somewhere cool, dry, and dark. Avoid direct sunlight and damp conditions.
Who makes DRVN?
DRVN was founded by Garrett, a vet working in emergency medicine and a lifelong combat sports athlete based in Cornwall. Training for his first kickboxing fight, he couldn't find a product built for genuinely high-intensity sessions — so he built one himself, then worked with a formulation team to bring it to production.
