Liam (the guy who runs HR Labs), doesn’t rest on his laurels… he’s constantly thinking of ways to take a good product and make it great – and essentially that’s what he’s done here with WATTR™.
Great ingredients, great flavours, great results – this is a staple daily drink for me now, whether I’m training or not. The ‘Frootz’ flavour (that definitely isn’t Vimto) tastes remarkably like Vimto! GrapeCurrant is pretty cool too.
Who it’s for:
Anyone training hard in the heat, competing back-to-back, or dealing with fatigue – they’ll benefit from this precise electrolyte replacement and energy support that hits both body and brain.
What it does:
About 1,035mg of smartly chosen electrolytes plus 1.5g of taurine to rehydrate muscles, support nerve function, and enhance fluid retention. The B-vitamins and AstraGin® double as energy metabolism and absorption boosters.
How I’d use it:
Drop a scoop into 500ml ice cold water before, during, or after workouts – or sip on it daily for clean hydration. Refreshing, functional, and smart.
The Science:
Electrolyte Solutions vs. Plain Water in Hydration Efficiency
Study: A randomised crossover trial using the Beverage Hydration Index (BHI) framework compared plain water to electrolyte-enhanced drinks over four hours – tracking fluid retention and urine output in healthy individuals.
Nutrients (Millard-Stafford et al., 2021)
https://pubmed.ncbi.nlm.nih.gov/34578811/
Electrolyte-containing beverages retained significantly more fluid than water alone – validating how WATTR’s high sodium-based blend better supports hydration and performance.
Electrolyte + Carbohydrate Drinks Enhance Endurance in Heat
Study: Multiple controlled trials on endurance athletes in hot conditions comparing carbohydrate-electrolyte solutions (CES) with plain water. Outcomes included improved endurance, fluid retention, and thermoregulation.
Journal of Athletic Training systematic review (ILCOR, 2023)

CES with electrolytes significantly outperform water for maintaining hydration and reducing fatigue – supporting WATTR’s role as a superior intra- and post-workout hydrator.
