I feel like myself again
I’ve tried a lot of supplements over the years, but this is the first one that made me feel the difference. My memory feels stronger, I have more mental clarity, and I’m even sleeping better.

A full 7-week supply of NAD+ support — more value in every bottle.
A smarter approach to longevity rooted in science, designed for everyday life.
NAD+ is essential for life — every cell in your body relies on it to function properly. Starting in your 30s, NAD+ levels begin to decline, and by age 40, they can drop by as much as 50%. This decline affects everything from cognitive performance to how your cells recover from stress and damage.
But the good news? You can take control — restore your levels, reclaim your energy, and thrive like never before.
1. Can you provide a copy of your third-party quality testing certificate?
Yes. Every batch of VivaThrive is independently tested, and Certificates of Analysis (COAs) are available upon request for full transparency and peace of mind.
2. Do you offer a customer satisfaction guarantee?
Yes. If you’re not happy after finishing your first bottle, we’ll provide a 100% money-back refund — no questions asked. Your trust and results are what matter most.
3. How should I take VivaThrive NAD+ Complex?
We recommend starting with 1 capsule per day, preferably in the morning with food, during your first week. If you feel good, increase to 2 capsules daily. Some users choose to take 3–4 capsules per day after 2–3 months based on their body’s response and wellness goals.
4. How is Nicotinamide Riboside (NR) different from regular vitamin B3?
NR is a naturally occurring, next-generation form of vitamin B3 that has been clinically studied. It helps restore NAD+ far more efficiently than standard B3 — powering your cells with the energy and repair they need to thrive.
I’ve tried a lot of supplements over the years, but this is the first one that made me feel the difference. My memory feels stronger, I have more mental clarity, and I’m even sleeping better.
Within the first week, I felt a noticeable shift — clearer thinking, more steady energy, and less of that mid-day crash. VivaThrive helps me stay mentally sharp, even on long workdays. My team at work even commented that I’ve been ‘on it’ more than usual lately.
The biggest difference for me has been sleep. I wake up refreshed and focused — not groggy. I feel like my body and brain are finally in sync again.
