Electrolytes Hub – Endurance Hydration & Electrolyte Supplements UK
Electrolytes are the most underestimated variable in endurance performance. Get them wrong and you cramp, fade, and struggle to finish. Get them right and you stay sharp, strong, and in control from start to finish. This hub brings together Hammer Nutrition UK's full range of electrolyte supplements all containing six different full spectrum electrolytes— and the science behind using them effectively.
Unlike most sports brands, Hammer Nutrition uses chelated minerals rather than cheap salt-only formulas. That means better absorption, less GI distress, and electrolyte balance that actually mirrors what your body loses during exercise.

Endurolytes – Balanced Electrolyte Capsules for Endurance
Endurolytes are Hammer Nutrition's flagship electrolyte capsules — a precisely balanced blend of sodium, potassium, magnesium, calcium, and manganese in chelated form for maximum absorption. Unlike sodium-only tabs, Endurolytes replace the full spectrum of minerals lost through sweat, making them the go-to choice for endurance athletes in the UK who want cramp-free, consistent performance.
Best for: All-day endurance events | Athletes who sweat moderately | Everyday training hydration
Endurolytes Extreme – High-Strength Electrolytes for Heavy Sweaters
When conditions are brutal — extreme heat, high humidity, or multi-hour efforts — standard electrolyte doses aren't enough. Endurolytes Extreme delivers a significantly higher sodium and electrolyte concentration, specifically formulated for heavy sweaters, hot weather racing, and athletes who consistently struggle with cramping. The same chelated mineral quality as Endurolytes, scaled up for when it matters most.
Best for: Hot weather racing | Heavy sweaters | Ultra-distance events | Summer training blocks
Endurolytes Fizz – Effervescent Electrolyte Tablets
Endurolytes Fizz delivers the same balanced electrolyte profile in a convenient effervescent tablet — just drop one into your water bottle and go. No measuring, no capsules, no fuss. Ideal for athletes who prefer drinking their electrolytes, or for events where swallowing capsules mid-effort isn't practical. A popular choice for cycling hydration and open-water swimming.
Best for: Cyclists and swimmers | Athletes who prefer drink-format electrolytes | Travel and racing convenience
Endurolytes Extreme Powder – High-Strength Electrolytes in Bulk
All the performance of Endurolytes Extreme in a flexible powder format. Endurolytes Extreme Powder lets you dial in your exact electrolyte dose — ideal for athletes with high sweat rates who need precise control, or for mixing into bottles during long training blocks. The most cost-effective way to maintain electrolyte balance during endurance training.
Best for: High-volume training | Athletes needing custom dosing | Cost-conscious endurance athletes

Why Hammer Nutrition Electrolytes?
Most electrolyte products on the market are little more than sodium chloride with flavouring. Hammer Nutrition takes a fundamentally different approach: every Endurolytes product uses chelated minerals — minerals bonded to amino acids for superior bioavailability and gentler absorption. The result is an electrolyte supplement that works with your body's physiology, not against it.
No artificial colours. No excessive sodium. No proprietary blends. Just the right minerals, in the right ratios, in the right form.
