Hydration + Energy is a clean, daily electrolyte drink with a researched energy upgrade. Each scoop delivers 1250mg of taurine and a full five-salt electrolyte profile, sodium, chloride, potassium, calcium and magnesium, alongside 100mg of natural caffeine and 200mg of L-theanine in a 1:2 ratio for focused, jitter-free energy. Just 0.1g of sugar, naturally flavoured, and honestly dosed. If it’s on the label, it’s in the product at effective levels.
Add one scoop to 400–500ml of cold water and shake or stir until dissolved. Take 20 minutes before training for focus, sip during long or hot sessions, or use afterwards to rehydrate. Do not exceed 4 servings per day. Not suitable for children, or those pregnant or breastfeeding, due to caffeine content.

The +Energy Upgrade

No spike. No 2pm crash at your desk. Just a steady, usable lift in energy.
Why it works
Fuel better, hydrate smarter.
Early Starts
Rehydrate after sleep and feel ready to go, without reaching straight for coffee.
No Midday Crash
Caffeine paired with L-theanine gives a steady lift, without the usual 2pm crash.
Replace Sweat Loss
Five electrolytes replace what you lose through sweat, so hydration levels stay balanced.
Long Days
When energy dips, it helps you stay sharp, focused and moving, right to the end.
Two ways to hydrate
Know which to reach for.
Energy in the morning, steady hydration the rest of the day. Hydration + Energy powers your training window; our caffeine-free Hydration covers everything after.
