Not all supplements are created equal. And, that’s hardly news.
The market is flooded with brands making bold health claims, and collagen is no exception. As a wellness writer, I’ve tried my fair share, and I’m often skeptical that I’ll see any real long-term difference in my hair, skin or nails. But if there’s one formula that’s catching my attention, it’s Elysium’s Cofactor.
This isn’t your ordinary collagen supplement. Cofactor blends clinically backed Premium Collagen Peptides, Hyaluronic Acid, Vitamin C and 250 milligrams of NR to support NAD+ levels — the coenzyme that biohacking enthusiasts have linked to cellular health and longevity. And right now, during Amazon’s Spring Sale, Cofactor is marked-down 35% off.
According to Elysium, Cofactor works by supporting your body’s natural ability to repair and maintain collagen — so it’s not just for hair, nails, skin elasticity and hydration, but also for overall vitality. Translation: internal and external benefits.
Reviewers are seeing the results, with one calling it the best collagen supplement they’ve tried. And that was just after the first month of use.
ELYSIUM Cofactor – 4-in-1 Collagen Peptides Powder w/NAD+
Amazon“My skin feels noticeably more hydrated and has a healthy glow that wasn’t there before,” the reviewer shared, adding that they love that it combines collagen peptides with NAD+.
The unflavored powder blends easily into any cold liquid, and each pouch contains 28 daily servings for a full month of support. According to Elysium, consistent use can lead to enhanced skin hydration within weeks and smoother skin with fewer visible wrinkles over time. Some users report benefits even sooner.
“It feels like I’m supporting my skin and overall wellness at the cellular level,” they added. “After just a few weeks, I’ve also noticed my joints feel less stiff, especially in the mornings.”
more best-selling NaD+ supplements
NAD+, backed by results: Elysium’s top-selling Basis supplement is clinically proven to boost NAD+ levels by 40% in a double-blind, placebo-controlled trial.
If you’re ready to crank up your NAD+ levels, the TRU NIAGEN PRO NAD+ is a great place to start. This formula has been shown to increase NAD+ levels within three weeks and is backed by decades of research.
The Liposomal NMN Pro Complete rapidly increases NAD+ levels and enhances cellular energy while optimizing mitochondrial performance. Triple-lab tested, thousands of consumers trust and use it.
