As a shopping writer, Amazon Prime Day is basically my Super Bowl. But this year, it feels like a breeze — and that's because of Tru Niagen.
The four-day shopping marathon (running through July 11) means our team is digging through thousands of Prime Day deals and writing around the clock to help readers find the best deals across the site. The days start early, the hours are long, and the pressure is on. Some stress is imminent. Or, at least it used to be.
I've been around for a few Prime Days, but this one feels quite different, and I believe I owe that to Tru Niagen's Immune supplement. These supplements aren't just the latest wellness craze; they're backed by 50 years of research and over 300 published studies. Thousands of reviewers have spoken about their benefits, from improved endurance and energy to immune support and longevity. Some have claimed that Tru Niagen is the reason they haven't had to take a sick day in years.
Between the chaos of prepping for Prime Day and chasing around a fussy toddler in my spare time, I've been running on very few hours of sleep — yet I still feel like I could crank out ten more articles. It's not magic; the only thing that I have added to my routine is this NAD+ boosting supplement.
The only real downside is the cost. Tru Niagen Immune Support normally comes with a steep $75 price tag. But for Prime Day, it's 25% off, which means now is the time for shoppers to stock up.
If you're feeling stressed in any sort of way, I'd seriously recommend giving it a try. I had my doubts at first, but here I am adding it to my cart.

Powered by the award-winning ingredient, Niagen has been shown to boost NAD+ levels, an essential compound your cells rely on for energy, focus, cellular health, and recovery.
I've only been taking Tru Niagen for a couple of weeks, but the results are already impressing me. The 4 a.m. brain fog? Gone. Typical mid-day crash? Dissappeared. Constant need for caffeine? Barely there. I've taken plenty of supplements, but this is one I've found that actually works.
With immune-boosting nutrients like vitamins D, C, and zinc, I'm also confident I'm getting the extra support I need to stay healthy during the busiest time of the year. If you're also juggling long shifts and balancing a tight schedule, Tru Niagen may be exactly what your body needs, too.
