The benefits of Xtend EAA

Muscle-building support

EAAs, in particular leucine, stimulate muscle protein synthesis, promoting muscle development and repair.

Prevention of muscle catabolism

During intensive training or periods of caloric deficit, EAAs help limit muscle fiber degradation.

Improved recovery

By directly supplying the necessary amino acids, they speed up recovery after exercise and reduce muscle soreness.

Supporting sports performance

Greater availability of EAA during exercise can delay fatigue and improve endurance.

All about Xtend EAA

What is EAA?

EAA, or essential amino acids, are the 9 amino acids that the body cannot manufacture itself. They must therefore be supplied through the diet or supplements.

Why use EAA?

EAA play a fundamental role in protein synthesis and muscle building. They are useful for improving recovery, optimizing performance and supporting muscle growth, particularly in athletes.

Description

image item

Xtend EAA contains the branched-chain amino acids isoleucine, leucine and valine, part of the 9 essential amino acids known as BCAAs.

Compared to other amino acids, BCAA's are metabolized in muscle tissue and not in the liver.

In the muscles, BCAA's serve as an energy substrate during exercise and as a precursor for the synthesis of proteins or other amino acids.

They prevent muscle wasting.

Swiss excellence for your fitness


Founded in 1999 by Pascal Guzzo, a sports, physiotherapy and nutrition enthusiast, STS was born of a simple conviction: better eating habits lead to better performance and better health.


As a physiotherapist and trainer of top-level athletes, Pascal quickly realized that even athletes often lack appropriate nutrition.

He then decided to offer them quality supplements, such as protein powder. Success was immediate! STS was born, and even obtained exclusive authorization to sell Whey Gold Standard in Switzerland, a first at the time.


Since then, STS has established itself as a key player in Switzerland, renowned for its irreproachable products, all manufactured in Europe or the UK and selected with the highest standards.

Guided by a strong ethic and the desire to help everyone regain their shape and vitality, the company now distributes to over 3,000 points of sale and continues to develop formulas perfectly adapted to the needs of the Swiss market.

Frequently asked questions

What is EAA?

EAAs (Essential Amino Acids) are amino acids that the body cannot produce itself. They must be supplied through diet or supplementation to support muscle growth, recovery and overall health.

What are EAAs used for?

They promote protein synthesis, improve muscle recovery, support sports performance and prevent muscle loss.

What's the difference between EAA and BCAA?

BCAAs contain only 3 essential amino acids (leucine, isoleucine, valine), while EAAs contain 9. EAAs are therefore more complete and more effective.

Who can consume EAA?

EAA can be consumed by athletes, active people, or those with a low protein intake. They are also suitable for vegetarians and vegans, depending on the formula.

Quand faut-il prendre les EAA ?

They can be taken before, during or after training. You can also consume them between meals to support your amino acid intake.

What is the recommended dosage?

The usual dose is between 5 and 10 grams a day. It is important to follow the recommendations on the product packaging.

Do EAAs taste good?

Yes, our EAA are flavored for a pleasant taste (red fruit, lime, tropical...) and dissolve easily in water.

Are EAA safe for your health?

Yes, they are safe when consumed in the recommended doses. They are natural nutrients essential to the body's proper functioning.

Can I take EAA with other food supplements?

Yes, EAA can be combined with other supplements such as protein powder, creatine, glutamine or vitamins.

Are your EAAs suitable for vegetarian or vegan diets?

Yes, our formula is 100% vegan, lactose-free, gluten-free and contains no ingredients of animal origin.
