WHY ATHLETES CHOOSE ENDUROLYTES
This capsule is the gold standard for endurance support. It provides a balanced blend of six electrolytes to help you maintain peak power.
Our chelated minerals ensure maximum absorption. Use them during intense training or racing. This formula targets sodium and chloride.
Hammer Nutrition takes a different approach by using highly bioavailable chelated mineral forms in Endurolytes®, Endurolytes Extreme capsules ®
The result? Better absorption, improved utilisation, and less digestive discomfort during training and racing.
What Are Chelated Electrolytes?
Chelated electrolytes are minerals that have been bonded to an organic compound, typically an amino acid.
The word "chelated" comes from the Greek word for "claw," referring to how the amino acid surrounds and protects the mineral molecule.
This protective bond helps transport the mineral safely through the digestive system where it can be absorbed more efficiently and delivered to the body where it is needed most.
Hammer Nutrition uses chelated mineral forms because endurance athletes don't just need electrolytes—they need electrolytes that can actually be absorbed and utilised effectively.
It helps prevent cramps by providing potassium and magnesium. The formula also includes calcium and Manganese for better recovery.
The low sodium content is ideal for specific diets. It suits athletes who maintain a healthy, lower-salt daily nutrition plan for health.
- Best for: Sessions over 2 hours and endurance sports like running or cycling.

Easy to use and nice taste.
On Saturday 14th September I stood on the start line at Bewts Y Coed. This was my 3rd 100 miler this year.
I have used Hammer since around 2010 in my Ironman days. As of today I have completed 428 marathons ‘all official races’ around the globe.. also quite a few ultras in my time.
I have used Recoverite on multi day ultras for the last 10 years. Great mix and flavour. I have converted many to this product.
