Modern Sports Hydration

Why The Dose Is What It Is

A hard, hot or busy hour drains 500 to 700mg of sodium. Most drinks give you 200 to 300. This closes the gap, not half of it.

Sodium plays a pivotal role in hydration. It increases fluid absorption, fluid retention, maintains electrolyte balance and stimulates thirst, thus increasing fluid intake. Research shows that drinks containing sodium can improve endurance, mood, and reaction times, whilst reducing the risk of cramps and hyponatremia.

Potassium works closely with sodium to maintain normal cellular fluid balance, nerve impulses, and muscle contractions. Potassium chloride specifically may counteract the effects of too much sodium, maintaining a healthy electrolyte balance.

Learn more

Magnesium is imperative for over 300 enzymatic reactions, including those that produce and use ATP, the body's energy currency. It aids hydration by moving water into cells, essential for muscle function, energy, and performance.

Lovely difference in this drink,

"Lovely difference in this drink, which is good to see variety, refreshing and brilliant for those long workouts"

Craig H. (5/5)

I’ve been using these hydration

"I’ve been using these hydration cans for the past few months and they’ve quickly become a go-to for me. With training and a busy day-to-day schedule, it’s not always easy to stay properly hydrated, but having something ready to grab from the fridge has made a big difference. No mixing, no prep—just open and go, which is ideal when you’re on the move. I’ve definitely noticed more consistent energy levels and better recovery after workouts, especially on the days where I’d normally feel a bit drained. The taste is spot on—not overly sweet or artificial—and it actually feels refreshing rather than heavy. For convenience alone they’re a win, but the fact you can genuinely feel the benefit makes them something I’ll keep using. Would highly recommend for anyone training, travelling, or just looking for an easy way to stay on top of hydration."

Grayham T. (5/5)
