Our advanced liposomal delivery system protects NAD+ molecules as they pass through your digestive system, allowing for up to 9x better absorption than standard supplements. Unlike competitors that rely on precursors your body may or may not convert, our formula delivers NAD+ directly to your cells where it fuels energy production at the mitochondrial level, helping you feel the difference faster and more consistently.
L-Arginine and L-Citrulline work together to support your body's natural nitric oxide production. This means improved blood flow to muscles, organs, and everywhere it matters most. Better circulation supports workout performance, faster recovery, and the kind of daily stamina that makes you feel like yourself again.
Saw Palmetto, Beta-Sitosterol, and Lycopene provide targeted support for long-term prostate health. These clinically studied ingredients help reduce nighttime bathroom trips, support healthy urinary flow, and address prostate concerns before they become bigger problems. Sleep better. Worry less.
Vivonu isn't designed for "as needed" use. It's built for men who want to support their circulation and vitality as a daily habit. Three softgels a day. No cycling on and off. No timing it around specific moments. Just consistent support that builds over time, so you feel the difference in your energy, stamina, and overall wellness week after week.
Customer Reviews
I have tried more supplements than I can count over the past ten years. Most of them ended up in the back of my cabinet after a month because I never felt any real difference. This one is different. About two weeks in, I noticed I was not hitting that wall around 2pm like I used to. My workouts have improved and I am not dragging myself through the last few sets anymore. The prostate support has been a game changer for sleep. I used to get up three or four times a night and now it is once at most. My wife even commented that I seem more like my old self. I am on my third bottle and have no plans to stop.
I was skeptical when I ordered this because the whole NAD thing felt like another wellness trend that would disappear in a year. But a buddy of mine who is a few years older kept telling me how much better he felt, so I figured I would give it a shot. Glad I did. The energy is noticeable but not in a jittery way. It is more like I just have a longer fuse throughout the day. I am less irritable by evening and I actually want to do things after work instead of just sitting on the couch. Recovery after lifting is faster too. I used to be sore for days and now it is maybe a day at most. Solid product.
At my age you start to accept that feeling tired and run down is just part of life. My doctor kept telling me my numbers were fine but I knew something was off. I did not want to go the prescription route yet so I started looking into supplements that actually had some science behind them. Found this one and decided to try it with the 100 day guarantee figuring I had nothing to lose. Honestly I noticed changes within the first month. More energy in the morning, better focus during the day, and I am not rushing to the bathroom every hour anymore. I feel like I got a few years back. I recommend this to any guy who is tired of feeling tired.

What exactly is NAD+ and why do I need it?
What exactly is NAD+ and why do I need it?
NAD+ is a coenzyme found in every cell of your body that plays a critical role in energy production and cellular repair. As you age, your natural NAD+ levels decline significantly, often by as much as 50% by the time you reach your 40s and 50s. This decline is linked to lower energy, slower recovery, reduced mental clarity, and many of the symptoms men associate with getting older. Supporting your NAD+ levels helps restore the cellular fuel your body needs to function at its best.
How is this different from NMN or NR supplements?
How is this different from NMN or NR supplements?
NMN and NR are precursors, meaning your body has to convert them into NAD+ before it can use them. That conversion process is not always efficient and varies from person to person. Our formula delivers NAD+ directly in a liposomal form that protects it through digestion and allows for up to 9x better absorption. You get the end product your cells actually need without relying on your body to make the conversion.
What does liposomal delivery mean?
What does liposomal delivery mean?
Liposomal delivery wraps the active ingredients in a protective lipid layer that shields them from breaking down in your stomach acid. This allows the NAD+ and other nutrients to pass through your digestive system intact and absorb directly into your bloodstream and cells. The result is significantly higher bioavailability compared to standard capsules or powders, which means more of what you pay for actually gets used by your body.
How long until I notice results?
How long until I notice results?
Most men report feeling a difference in energy and focus within the first two to three weeks. Improvements in workout recovery and stamina often become noticeable around the same time. Benefits related to prostate health and sleep quality typically develop over four to six weeks of consistent use. For full results across all three systems, we recommend giving it a full 90 days, which is why we offer a 100-day guarantee.
Are there any side effects?
Are there any side effects?
The formula contains only natural ingredients at clinically studied doses with no stimulants or artificial additives. The vast majority of users experience no side effects at all. Some men notice a mild adjustment period during the first few days as their body adapts, but this typically passes quickly. If you have specific health concerns or are taking medications, we recommend consulting with your doctor before starting any new supplement.
Can I take this with my current medications?
Can I take this with my current medications?
While our ingredients are natural and generally well-tolerated, we always recommend consulting with your healthcare provider before adding any supplement to your routine, especially if you are taking blood pressure medications, blood thinners, or other prescription drugs. Your doctor can review the full ingredient list and advise based on your specific situation.
How do I take it?
How do I take it?
Take two capsules daily with food, preferably in the morning or early afternoon. Taking it with a meal that contains some healthy fats can further enhance absorption of the liposomal ingredients. Consistency is key, so we recommend making it part of your daily routine at the same time each day.
