Matakana Health Appoints Lleyton Hewitt As Brand Ambassador For Tru Niagen In Australasia

As tennis season officially kicks off in Auckland this week, New Zealand company Matakana Health, distributor of Tru Niagen, the global leader in NAD+ supplementation, announces the appointment of Australian tennis legend Lleyton Hewitt as the brand’s new Australasian ambassador. This collaboration brings together two names equally committed to quality, discipline, and performance, announced just as the ASB Classic begins in Auckland.

At the heart of this partnership lies a common philosophy: results, not hype. Tru Niagen, featuring patented nicotinamide riboside (NR), is the most efficient, effective, and high-quality NAD+ booster available. A coenzyme vital to cellular health, NAD+ plays an essential role in creating cellular energy production and DNA repair. NAD+ declines with age and exposure to everyday lifestyle stressors, contributing to age-related changes in health and vitality. Clinically proven to elevate NAD+ by up to 50%Tru Niagen is backed by the highest scientific and quality standards, including 40 peer-reviewed published clinical studies, 500+ published scientific studies, and has been approved for use by some of the world’s most rigorous regulatory bodies.

Likewise, Hewitt built his career on discipline, evidence-based training and recovery, mental toughness, and an unwavering will to improve. The father of three, two-time Grand Slam champion and former world no.1 has always had an approach to the game that was never about shortcuts or glamour, it was about doing the work, day after day, match after match.

“I started taking Tru Niagen because it is the gold standard in NAD+ boosting and the highest quality supplement out there,” says Hewitt. “I want people to see that you do not have to rely on empty promises. Whether in sport or health, you should demand accountability, commitment to results, and performance. That is what this brand is all about.”

Hewitt is renowned not just for his greatness on court, but for his integrity, humility, and authenticity. His reputation for grinding through adversity mirrors Tru Niagen’s unwavering commitment to transparent science, third-party validation, and publishing clinical data. This partnership embodies real-world credibility and long-term commitment to wellbeing.

A hallmark of Hewitt’s career was his capacity to bounce back, from injuries, tough matches, or slumps. The mission of Tru Niagen is complementary: supporting the body’s inherent capacity to repair at the cellular level. As NAD+ levels naturally decline with age, Tru Niagen aims to provide support for health, resilience and recovery at any stage of life.

Lleyton Hewitt rose to the top of the tennis world through sheer grit and competitive spirit. He captured 30 ATP singles titles, including two Grand Slam singles (2001 US Open, 2002 Wimbledon), a doubles major (2000 US Open), and back-to-back year-end championships in 2001 and 2002.

He first became world No. 1 on November 19, 2001, and held that ranking for 80 weeks, finishing as year-end No. 1 in both 2001 and 2002. He also played a pivotal role in Australia’s Davis Cup victories in 1999 and 2003.

Today, Hewitt continues to give back, as a coach, a mentor, a Davis Cup captain, and a father. He inspires young athletes to aim higher, to work harder, and to recover smarter. In the same way, Tru Niagen aspires to empower individuals beyond sport, from high performers to everyday people, to operate at their best, now and into the future.

“We believe this is more than a brand-celebrity tie-up,” said Kevin Glucina from Matakana Health. “It’s an authentic alliance built on shared values: evidence, endurance, and empowerment. With Lleyton, we can not only communicate a message of health — we can embody it.”
