Why NoDoubt?
I never thought that ageing would bring new challenges in maintaining my fitness level. It has now become obvious that the right diet with sufficient leucine is extremely important to achieve my sporting goals. NoDoubt introduced me to the ideal solution for my age-specific needs and gave me the opportunity to feel young, healthy and fit.
Martino Goretti
Four-time world champion, four-time European champion and two-time Olympic champion in rowing
Martino is a lightweight rower and was a four-time world champion and four-time European champion between 2003 and 2022. He also won countless other titles in the eights, fours and skiffs and took part in two Olympic Games. Martino was born in 1985. He is married to Sophie Souwer and works as a rowing coach in Switzerland.
His greatest sporting successes:
6x World Championship gold
4x European Championship gold

Why NoDoubt?
As a professional rower, I spend countless hours both on the water and in the gym to continuously improve my performance. In this demanding environment, an increased intake of leucine and omega-3, in addition to protein, plays a decisive role in outperforming my younger competitors in all aspects. NoDoubt’s focus on concentrating on the specific requirements allows me to reach and maintain my maximum performance.
Ronnie Schildknecht
Multiple winner of the Ironman Switzerland and Swiss duathlon champion
Ronnie is a former Swiss duathlete and triathlete. He was active from 2000-2021 and is a multiple Swiss duathlon champion, eleven-time Ironman winner and is listed as the best Swiss triathlete over the Ironman distance. Ronnie was born in 1979 and lives with his wife and daughter in the canton of Zurich. Since his retirement, he has worked as a sports manager and coach.
Nickname: I-Ron
His greatest sporting successes:
11x Ironman winner
Vice World Champion Duathlon
6x Swiss duathlon champion
Why NoDoubt?
Rapid recovery is crucial in endurance competitions. As an ex-professional triathlete, I have found it difficult in recent years to recover sufficiently after intensive training sessions. It was only when I came across NoDoubt Protein that I realized that I need to pay more attention to my regeneration as I get older. NoDoubt Protein focuses on maximum regeneration strategies with natural goji berry extract and makes me feel like I’m sitting in a time machine.
Patrick Heuscher
Bronze medal winner at the 2004 Olympic Games in beach volleyball and multiple Swiss champion
Patrick is one of the most successful beach volleyball players in Switzerland. Together with Stefan Kobel, he became five-time Swiss champion. In 2004 he won the bronze medal at the Olympic Games in Athens and twice the bronze medal at the European Championships. He retired from active top-level sport in 2013. Patrick was also an athlete ambassador for the development aid organization Right to Play. He now works as an entrepreneur.
His greatest sporting successes:
5x Swiss champion
Bronze Olympic Games
2x Bronze European Championships
Why NoDoubt?
“As I’ve got older, I’ve relied more on my diet to keep me fit and healthy. However, in my everyday life, I find it increasingly difficult to meet my increased protein requirements. NoDoubt takes an innovative approach that not only fortifies protein, but also contains leucine, goji berry extract and omega-3. This combines high quality protein with essential elements and is particularly unique for active people over 40.”
Sophie Souwer
World rowing champion, multiple silver and bronze medal winner at world and European championships, Olympian
Sophie Souwer started rowing in 2007. Between 2013 and 2022, she won several silver and bronze medals at world and European championships in the quadruple scull and eight boat classes. At the Olympic Games in Rio, she took sixth place in the eight and an outstanding seventh place in the single scull in Tokyo.

Her greatest sporting successes:
1x World Championship Gold
2x World Championship silver
1x World Championship bronze

2x Olympic participation
Why NoDoubt?
Over the years I have noticed that nutritional guidelines are mainly developed for male athletes. Women have a unique physiology, different requirements and hormonal profiles. What if the inadequate consideration of these differences has a negative impact on my performance? NoDoubt is dedicated to understanding this and has bundled its knowledge into a simple but highly effective product.
Dr. med Peter Dür
Sports physician and pulmonologist
Dr. Peter Dür is a sports physician and pulmonologist. In his youth, he was a competitive cyclo-cross athlete. He was a senior physician in the cantonal hospitals of Zug, Schwyz and Lucerne, was medical director of Solothurner Spitäler AG and is now head of a practice in the canton of Zurich.
Dr. Peter Dür is married and the father of three adult children. Even today, he still rides over 10,000 km a year on his racing bike.
Why NoDoubt?
In an ideal world, there would be one universal dietary guideline, but the reality is far more complex. We often underestimate the potential for peak performance in people over 40 or female athletes because we don’t emphasize the right ingredients. Muscle loss is a natural process that can begin as early as 30. The combination of sufficient protein with leucine, goji berries and omega-3 can support our changing physiology preventively and thus have a noticeable effect.
Proteins for Active People Over 40:
NoDoubt SilverGreen
From the age of 30, our body undergoes natural changes that affect our fitness and health. Muscle mass decreases, especially in the 40s, and muscle regeneration slows down considerably. This leads to a decline in your strength and performance.
Discover solutions that enable you to counteract muscle loss at an early stage and maximize your performance from the age of 40.
Proteins for Women Under 40:
NoDoubt AmberBlaze
Women have long been neglected in sports science. The female cycle was seen as a disruptive factor, which meant that recommendations were often based on male needs and ignored the specific requirements of women.
Discover solutions that tackle nutrient deficiencies from the ground up and maximize female performance.
