About

sis

SIS is the pioneer in sports nutritioN

since its founding in 1992 by top cyclist Tim Lawson. Throughout this period, SiS has worked closely with leading research institutes, scientists and top athletes.

We support athletes

who share the same values and who set an example for others. Inspired by the best practices in the industry, we want to provide the best nutrition opportunities for endurance enthusiasts. The endurance is no longer just a marathon and a triathlon. In most popular sports, endurance is the key to success.

SIS has revolutionized sports nutrition

In 2016, SiS launched WHEY20, the world's first protein gel.

In 2013, the world's first nitrate gel was launched - helping to improve oxygen consumption.

In 2002 the world's first isotonic energy gel was launched - designed to be consumed without water.

With Science in Sport,

you can be sure that you only consume the best that science and sport combined has to offer.

SiS stands for clean sport

All products are Informed Sport tested. In the 2016 Rio Olympics, 34 medal-winning athletes or teams used SiS products.

We understand

the early morning workouts. We know what training in cold and dark means; we can cope with hot and humid climates; our DNA is self-transcendence, we know about 20 of the most popular sports.

You can always ask for advice

We have made sports nutrition a lot easier. You don't have to be Chris Froome or Saskia Alusalu to experience self-transcendence and recognition. We all deserve to feel good during and after exercise. Trust the best in their field.

Informed Sport tested

Science in Sport is the only brand globally to hold both Informed Sport Site Certification and Informed Sport Product Certification.

Every single batch of Science in Sport finished product which leaves the Company’s factory is screened against the 2018 World Anti-Doping Agency (WADA) list.

Only a very small number in the sports nutrition industry and no other brand globally holds both the Informed Sport Site Certification and Informed Sport Product Certification.

Science in Sport over the last 25 years has developed a reputation at the highest level of international sport and a supporting element is our approach to banned substances.
