“Just minutes ago, I was standing at my kitchen counter and could barely hold my head up. After two scoops of Vitality Boost, I was online looking at tile at Home Depot and about to bolt out the door. Wildest thing.”

-Kathyrn, best selling author, mom, and speaker who was two days into having Covid at the time.

Parkinson’s Disease

“I’m extremely happy with my latest nad test done January 18. Current levels are 58.9
Here is the progress starting with April 16, 2022: 24.9, 23.4, 34, 33.6, 42, 58.9

Your nmn and testing works. Even with Parkinson’s my energy levels are good.”

-David, retired professor and noted health expert.

Running and Exercise

“I recently purchased the Vitality Boost in October of 2023 and have used it since…I didn’t know that it could increase energy and improve performance, and being in the Military while on deployment has given me that extra boost to get me through my long days. 

…This product couldn’t have come at a better time since I was preparing for the Athens Marathon in Greece on November 12th, 2023. I finished 608th of 21,598, averaging a pace of 7:30 seconds for a distance of 26.2 miles. For proof, check out my Instagram @ _mas_oficial, which shows my race results! This was my first marathon, and being a 31-year-old male, I felt like I was in my early 20s. I feel more energized and focused throughout the day while in the field. Regarding gym exercise, I’ve been improving my bench, squat, and deadlift.”

Chasing Kids

“I’m almost done with my first jar and I can’t believe how my energy levels have improved. I’m finding myself smiling more often and feeling overall much more relaxed. My boyfriend’s nieces and nephew roped me into playing a basketball game with them over Christmas and despite having done no cardio or regular workout sessions for a few years now, I had plenty of energy even after running back and forth across the gym for probably a solid half hour before the kids finally got bored. The energy improvement is very tangible. The mood improvement is subtle but still noteworthy”

—Emily P. 

Walking, Stamina, Drive

“I have used other NAD products but at 75 years old, I was still testing just low normal, and not feeling able to complete my normal day and workouts with vigor. After six weeks using Jinfiniti’s Accuri Vitality Boost I am back living like I was 25 years ago… 5 -10 mile hikes, full days of meetings and studying… and having fun again!. My wife is also back to our expected normal activity levels…” thank you Dr. She from both of us! “

—Bruce Ross

Anxiety & Mental Health

“I felt like my brain was broken. I was so tired. I battled high levels of anxiety, having panic attacks three times a week, I felt fatigued all the time and needed 400 mg of caffeine and 2 naps per day just to function. It felt like a single setback could slide me off the cliff.

Initially, I did a big round of NAD IV, which was $4000, but I was desperate. It gave me a lot of energy and mental lift, but it wasn’t sustainable. A few months later, I was feeling the same. And then I discovered Jinfiniti. My NAD levels were sorely deficient. 

Within several months of taking the Vitality Boost, my energy is much higher, my mental health and anxiety is so much better, and I’ve even lost some of the unwanted stubborn weight that wouldn’t go away. And my NAD levels are now optimal at 55.4 thanks to Vitality Boost.

My husband and I feel we have our lives back and I know Jinfinti’s been a huge part of that.”

—Sarah W., one of our monthly subscribers of Vitality Boost.

Mental Clarity, Postpartum, Recovery

“After Dante was born, I still regularly experienced higher than normal levels of fatigue (like my cells were tired). I didn’t wake up as energized as I used to and my recovery wasn’t as good after a workout. I had some lingering brain fog and lack of mental clarity. Metabolism seemed to be lower. 

After two weeks of taking Vitality Boost, my brain fog has lifted, my metabolism is coming back and I’ve even felt some of that postpartum baby fat shedding faster. I feel better, happier, and more alert when I wake up. I am bouncing back faster and better from workouts. I am back to myself, which feels amazing.”

—Dr. Jennifer Fraboni (Doc Jen)

Severe Fatigue

“Over the last year, I started experiencing really debilitating fatigue in the afternoon. About six months ago, I did the NAD test and got shockingly low results coming in deficient. I’m perfectly healthy. I don’t have any diagnosed medical conditions. I exercise regularly, I eat well, and I’m not overweight. 

I was so appalled and determined to start taking the supplements regularly. 

Two weeks into taking the NAD supplement, the fatigue disappeared. I was absolutely astonished. I’m not going to stop taking the supplements to see if the fatigue comes back. I’d recommend the Vitality boost to anyone who needs extra energy.”

—Dr. James Goodwin, Director of Brain Health Network, London, UK.

“I have been using the supplement for the last 2 months. During this time I have increased my movement and feel strong and energized over the whole day. I’m a full time working mum and love all kinds of exercise. The best thing is the even energy all day so I can train/exercise/move whenever.”

—Louise N.

Overall Vitality

When my friend gifted me Vitality Boost I was skeptical however this skepticism has turned into gratitude for Jinfiniti. Vitality Boost has exceeded my expectations as a comprehensive wellness supplement. The promised benefits of increased energy, enhanced performance, improved sleep quality, and reduced inflammation have been noticeable in my daily life. 

I’ve experienced a significant reduction in muscle and joint pains, and the positive impact on allergic and asthmatic symptoms is truly remarkable. The supplement’s influence on mental clarity and dementia symptoms adds an extra layer of appeal. The promise of improved health functions, including the liver, kidney, heart, and thyroid, provides a sense of overall well-being. Vitality Boost lives up to its claims, making it a valuable addition to my wellness routine.”

Research news: NAD is showing significant promise in treatment neurodegenerative diseases, traumatic brain injury, diabetes, stroke and other health challenges from this research paper

“The preservation of cognitive ability by increasing nicotinamide adenine dinucleotide(NAD+) levels through supplementation with NAD+precursors has been identified as a promising treatment strategy for a number of conditions; principally, age-related cognitive decline (includingAlzheimer’s disease and vascular dementia), but also diabetes, stroke, and traumatic brain injury.”

Reading these reviews warms our hearts and reignites our passion for what we’re doing here at Jinfiniti with our groundbreaking NAD tests, biomarker panels and Vitality Boost (which we back with a 60-day Money Back Guarantee).
