Consumers are drowning in hacks, supplements, and bio-optimisation advice, but when burnout, fatigue, and illness hit, what actually works?

For years, the wellness industry has promised more energy, better performance, and endless optimisation. From supplements and wearable trackers to cold plunges, peptides, and biohacking routines, consumers have spent billions chasing ways to become healthier, sharper, and more productive.

As winter arrives and energy levels dip, sleep quality deteriorates, and stress accumulates, a growing number of wellness experts believe the industry is confronting an uncomfortable reality: many people are trying to optimise bodies that are already running on empty.

The numbers suggest the problem is bigger than seasonal fatigue. According to Stellenbosch Business School, 36% of South African workers experience excessive daily stress, while more than 71% are disengaged or actively disengaged at work. The economic cost of poor mental health and burnout is estimated at R161 billion annually.

According to Iain De Havilland, founder of NADclinic, the wellness conversation is beginning to shift away from performance and toward recovery.

“People are overstimulated, overworked, and biologically depleted, and winter exposes the difference between temporary stimulation and genuine resilience,” says De Havilland.

“What we’re seeing is the emergence of a recovery economy. Consumers are becoming less interested in the next wellness hack and more interested in sustainable energy, quality sleep, stress management, and long-term health.”

The shift reflects growing consumer scepticism around trend-driven wellness advice that often dominates social media.

“Consumers are hearing terms like longevity, biohacking, peptides and optimisation everywhere, but many don’t fully understand the science behind them,” he says. “Increasingly, people are asking a more important question: Does this actually help me recover?”

One area attracting growing attention is NAD+, short for nicotinamide adenine dinucleotide, a naturally occurring coenzyme found in every cell of the body. NAD+ plays an important role in cellular energy production, mitochondrial function, and DNA repair, and has become a focus of research into ageing, metabolism, and recovery.

“NAD+ is often misunderstood because it gets grouped with broader wellness trends,” says De Havilland. “It’s not a stimulant, and it isn’t designed to create an artificial boost. Its role is to support the biological systems responsible for energy production and cellular repair.”

He notes that confusion also exists around NAD+ and peptides, which are frequently discussed together despite serving very different functions.

“Peptides act as signalling molecules that trigger specific biological responses, while NAD+ is involved in the cellular processes that underpin energy metabolism and repair,” he explains.

The distinction matters, he says, because consumers are increasingly looking for evidence-based approaches rather than marketing promises.

“As people become more informed, we’re likely to see less interest in wellness theatre and more focus on measurable outcomes, whether that’s improved sleep, better recovery, healthier ageing or sustainable energy.”

De Havilland believes the future of wellness may ultimately be less about chasing performance and more about rebuilding foundational health.

“For years, the industry sold optimisation,” he says. “The next chapter will be about resilience. Winter simply has a way of revealing which approaches genuinely support health and which ones only create the illusion of it.”
