FAQs
🔹 What is NR, and why is it important?
NR (Nicotinamide Riboside) is a direct precursor to NAD+, the coenzyme that fuels cellular energy, metabolism, and DNA repair. Since NAD+ levels decline with age, NR supplementation helps support long-term health and longevity.
🔹 How is NR different from regular NR supplements?
Our Delayed Release Technology protects NR from stomach acid breakdown, ensuring better absorption and sustained benefits compared to standard NR capsules.
🔹 Is NR suitable for vegans?
Yes! We use vegan-friendly HPMC capsules, making it 100% suitable for vegetarians and vegans.
🔹 How long does it take to feel the effects of NR?
Some users report benefits within days, while others experience gradual improvements over weeks as NAD+ levels stabilise.
🔹 Is NR legal in the UK?
Yes! Unlike NMN, NR is fully approved as a novel food by the UK’s Food Standards Agency (FSA), making it completely legal for sale and consumption.
