Who Endurance Amino Is For
Endurance Amino is designed for athletes training and competing across long-duration disciplines including cycling, running, rowing, triathlon and ultra-distance events. It is particularly useful during sessions lasting two hours or more, when amino acid availability becomes a relevant consideration for sustained output. Whether you are following a long-distance endurance nutrition plan or looking for running, cycling or triathlon nutrition guides, Endurance Amino fits naturally into your protocol.
Targeted BCAA Formula for Endurance Training
Each four-capsule serving delivers a 2:1:1 ratio of branched-chain amino acids alongside L-alanine and reduced glutathione.

How and When to Use It

Endurance Amino vs Anti-Fatigue Caps
These two products serve different purposes and are not interchangeable. Endurance Amino provides branched-chain amino acids (leucine, isoleucine, valine) along with L-alanine and reduced glutathione — ingredients relevant to amino acid availability and antioxidant support during training. Anti-Fatigue Caps addresses a separate mechanism and is formulated to be used alongside Endurance Amino rather than instead of it. Many athletes use both during sessions of three hours or more.

Endurance Amino FAQs
Can I take Endurance Amino every day?
Yes. It can be used on both training and rest days. Follow the label directions for daily use guidance.
Is Endurance Amino suitable for vegans?
Yes. The formula uses a vegetable capsule (plant cellulose and water) and contains no animal-derived ingredients.
Can I use Endurance Amino with other Hammer Nutrition products?
Yes. It is designed to complement Hammer energy fuels and is included in the Race PB Kit alongside other Peak Performance supplements.
What is the difference between Endurance Amino and Amino Age?
Endurance Amino is formulated for endurance training and racing, with a BCAA-focused profile. Amino Age has a broader amino acid profile and is intended for daily nutritional and healthy-ageing support.
Do I need BCAAs if I already use a protein supplement?
BCAAs and protein supplements serve related but distinct roles. Endurance Amino provides free-form amino acids that are available quickly, without the digestion time required for whole protein. Whether you need both depends on your training volume and dietary intake.

Let customers speak for us
Extremely useful to use whilst cycling, removes the faff of opening gels whilst cycling and the solid bottle makes it easy to get in / out of jersey pockets.
Brilliant product - i use these in all my endurance events - some lasting up to 20 hours. These are great to ensure you get the required electrolytes without over hydrating.
Great service and the products are amazing, especially for endurance sports. I'm a big fan of the Endrolytes Electrolyte Caps. Their magnesium supplement and vitamin D are also very very good! I would highly recommend.
I’ve used Hammer products for around 6 years now & my favourite by a mile is the hammer Perpetuem, it’s fueled my last 100 mile ultra marathon not to mention multiple long distance triathlon's . It has 180calories per serving and it’s 34g of carbs & 5g of protein seems to work well . I’d strongly recommend for anyone who wants to take on ultra races as this fuel will support you when you need it most .
I started using Hammer Heed and Perpetuem 5 years ago and it's been such a game changer for my. Finding nutrition you can trust is so important for any athlete and I highly recommend Hammer Nutrition for any distance and any sport.
I couldnt race without hammer products. Heed is my favourite, such an amazing product. Paired with the gels it makes a great fueling recipe. Always fast shipping
Wonderful product for general Well being and Recovery. Great quick shipping.
Love all your products. I personally will concentrate on the perpetuum for my long swim(45km) as it feels like a meal every 4mins.
Thank you
great taste! great weight to calorie ratio! thanks
Great quality feel and easy to drink from whilst riding.
No plastic smells either.
Just need a few different colours?
Help me through a 70 miler. Would recommend 👌
