The “3 PM Crash” That Disappeared After 4 Weeks Changed Everything for This Grandmother

For years, Christchurch grandmother Jen accepted that exhaustion was just part of getting older. She’d given up night shifts six years ago, struggled through afternoon energy crashes, and assumed this was simply her new normal.

“I’d hit 3 PM and feel like someone pulled the plug,” Jen recalls. “Coffee helped for maybe 20 minutes, then I’d crash even harder.”

But this winter, something unexpected happened. Jen signed up for night shifts again – something she hadn’t dared attempt in over half a decade.

The Conversation That Started It All

The turning point came during an autumn visit from her son, who kept mentioning something called NAD+.

“He was going on about this molecule that apparently powers our cells,” says Jen. “Said it drops dramatically as we age, which might explain why people in their fifties and sixties feel constantly drained, even with good sleep.”

According to Cambridge-trained neuroscientist Zera Mariyam, this cellular decline is more significant than most people realize. “When NAD+ levels drop, your cellular power stations – the mitochondria – literally dim like a torch with fading batteries,” she explains.

The numbers are startling: by age 50, most people have lost 50% of their NAD+ levels. By 60, it can be down to just 20% of youthful levels.

What Changed After Week Four

Jen’s son had mentioned a compound called NMN (nicotinamide mononucleotide) that the body converts directly into NAD+. While it exists naturally in foods like broccoli and avocado, you’d need to eat over 20 kilograms daily to get a meaningful amount.

“I figured I’d try it for a month,” Jen says. “Around week four, I realised something odd – I hadn’t thought about my afternoon crash in days. It had just… quietly disappeared.”

The transformation went beyond just avoiding energy slumps. “I finished my first night shift tired but not shattered. The next morning, I was actually ready for the grandkids. That’s when I knew something was different.”

The Unexpected Bonuses

While Jen initially focused on energy levels, she noticed other changes she hadn’t anticipated.

“My skin looks brighter, which my daughter-in-law noticed before I did,” she laughs. “And my hairdresser asked what I was doing differently because my hair was growing faster.”

Early research into NMN supplementation is generating excitement in the longevity science community, with studies suggesting it may support various aspects of healthy aging beyond just energy production.

“I Just Want Energy for the Moments That Matter”

Today, Jen maintains a schedule that would have seemed impossible just months ago – volunteering, family time, and yes, back to those regular night shifts.

“It’s not about feeling 25 again,” she explains. “It’s about having enough in the tank to say yes to life. To pick up grandkids without worrying about energy. To volunteer without counting the hours until I can rest.”

For those experiencing similar midlife energy struggles, Jen’s story raises an intriguing question: what if exhaustion isn’t an inevitable part of aging?
