More Focus, More Energy, Better Days!

NAD Regen has been a great addition to my routine. I’ve experienced increased daytime energy, improved focus, and a reduction in mental fatigue and brain fog. Overall, I feel more mentally refreshed and clear-minded. This is a game changer!

Improve your life

If you want to take something that will make you feel invincible in the morning, then this is not it. If you want to take something everyday and a few weeks later notice that you have more pep in your step and dread getting up and going less than you have in years then this is the product for you. I truly believe NAD REGEN is making my life better because when I quit taking it for months last year I noticed a slow decline which seems to have come back now. I order either 6 months or a year supply at a time since I work out of the country for months and never know when I’ll be home. I would definitely do a subscription if I had a normal job/life and was home on a routine basis.

9 Month Review

It has been nine months to the day since I started taking this product. I am 35 and have been on a journey lately to find the right supplements and products that will help me be proactive in aging. There have been no earth shattering effects from this NAD but I can say that I definitely see improved energy. Slowly and quietly I didn’t need energy drinks anymore and even rarely do I need coffee in the mornings. It took time to see the effects but I believe I will notice it even more in the years to come using this NAD.

Invest in your Future

Picking NAD Regen is hands down one of the best decisions I’ve made so far. For those of you who are new to it, ensure to take it daily as instructed for optimal benefits. Consistency is key. You will feel the difference in your body and will thank yourself you found this product. If you’re about longevity, this is for you.

I love my NAD!!

I feel like it gives me the energy in the am to power through workouts even when I feel too tired and not motivated before taking it, suddenly I feel I could get through anything, I am 57 and make it through the toughest LagreeRed workout!

That is amazing, Anna! Thanks for sharing your results.

Rejuvenation and Menopause Relief

BioStack has been wonderful and it was the perfect time for me try them. Two days before receiving the product in the mail I was diagnosed with H-Pylori. I had been traveling and likely contracted it while on vacation. The meds I was given made me so sick and I was unable to tolerate food and suffered from extreme stomach spasms.

So I switched gears knowing, as an Ayurvedic coach, there’s herbs for that. I also wondered if BioStack could help with the rejuvenation process. And it DID! In a matter of two weeks I not only resolved the H-pylori infection, I had more energy, less brain fog, better sleep patterns and my bowels were back to being regular. Amazing results as prior to the infection I had also be battling through the Menopause Transition. BioStack has definitely helped me manage some symptoms.

So far so good!

Both my husband and I have been taking it every morning for about a month now and we both notice that we have more energy throughout the whole day. He also notices that he has more clarity and focus. He’s been raving about it to his students. We teach Jiu Jitsu, therefore we need to have the energy throughout the whole day to last us through all the day/night classes and this seems to be the one thing that’s made the most difference. We highly recommend it!

Strong Start

I am about a week away from my first month in. So far I have noticed positive improvements in how I feel and how I look. My spots of grey do not seem as prominent. I will need to update this after I get my 3 months in but I am pleased with the product at this time.

Great product. Feeling increase in energy and less naps needed. Looking forward to seeing what happens in the next 60 days of using nad

New customer, super happy!

I've been a biohacker for several years and after reading Dr David Sinclair's book Lifespan, I realised that NAD was a 'must have' in my supplementation stack. I was delighted to find BioFit supplied a high quality product and although its early days for me, I'm very happy with the results so far.

I found the fountain of youth.

I started my journey 6 months ago and found all of their claims to be true. I am 47 years old and had testing done to show my biological age was actually 51. I have tests to prove a drastic reduction in my biological age, cholesterol levels are lower than ever, and I look and feel years younger. I couldn’t recommend this product enough!

I’m about two weeks in. I believe I have increased energy, Drive and motivation. We will see as time goes on how that changes and improves.

Amazing for energy boost and overall Health

Noticed improved energy levels, focus and gym performance. Not to forget better sleep. Bought the product as was facing spinal issues with multiple disc buldges and disc degeneration. Looking for further signs of improvements in the months to come to return to my daily routine!

Game Changer

I must have been completely NAD depleted, because I feel like I noticed a change as soon as I started taking this. I'm rounding out month 3 and returning to restock my supply. I take this first thing in the morning and within 10 minutes, I feel the transition from zombie mode to feeling alive and full of vitality. I've taken NAD+ via injection but this is so much easier, plus it's a daily supplement so the effects are felt every day and not just on injection days. I honestly don't know how I ever survived without this stuff. Looking forward to trying the new and improved version as well.

That youthful boost

My wife (of almost 50 years) and I have been using NAD Regen for about 3-4 months now and it is now a regular daily staple in our routine. It gives us both that youthful boost to our day. I prefer the NAD Regen over the injections I was giving myself. It’s not only easier to take capsules, the Regen Mix spreads out the joy.

Almost 30 day in

I feel like I can tell that I have more energy and alertness taking Regen but I want to continue for the next 30 days to really be able to verify that these supplements are the reason.

NAD Regen WORKS

Been about a month and I have noticeably more energy already, especially early afternoon. I'm a believer.

I started feeling better after only a few days

I started feeling better after only a few days on NAD Regen. Hoping it continues because this is a better option for me than NAD injections

1 year later, I love this stuff!

I have been using NAD Regen for a little over a year now, and my energy levels have been amazing. All other things- diet, training, sleep and work being the same, I have had noticeably more energy and drive and my extra activities as well as physical work everyday have been seemingly effortless. I’m in it for the long haul now!

NAD Regan is amazing

NAD Regan is amazing. I wasn't expecting to much when I first tried it .I've been using countless supplements for many years to get a little more performance out of my trading and everyday life. I can tell a difference when I take this

NAD REGEN is a winner!

My husband and I started using NAD REGEN a few years ago after a good friend recommended it to us, and we love it! Both our cholesterol numbers went down…we read about some people who also said this and we were a little skeptical at first…but lo and behold, it was the case for us too! We are committed to BioStack and their products. 🤩

I started using the product over a year ago and

I started using the product over a year ago and it has made such an impact in my overall wellness and health. I never knew how important NAD was for men over 50. It’s much more practical and less expensive than the IV shots that require a daily visit.

Why NAD3® Matters as You Age

Instead of just topping up NAD+, NAD Regen helps your body protect, produce, and recycle its own supply—
so your cells can keep doing what they do best.

NAD+ levels are a supply & demand problem
Our natural NAD+ supply halves every 20 years. But our requirement for NAD+ increases as we age. NAD3®, along with the other ingredientsin NAD Regen, work to improve supply whilst lowering demand.

1

Enhances NAD+ Synthesis

Helps your body make more NAD+
NAD3® supports your natural production of NAD+, the molecule your cells rely on for energy, focus, and repair.

2

Preserves NAD+ Integrity

Protects what you already have
NAD3® works like a shield against NAD+ breakdown, helping you hold on to this critical fuel for cellular health and resilience.

3

Activates Longevity Pathways

Switches on healthy-aging signals
Beyond supporting NAD+, NAD3® also activates pathways tied to cellular renewal and long-term vitality.

Beyond BOOSTING NAD+ LEVELS

NAD3® boosts NAD+ levels, activates longevity pathways, and reduces aging stress.

This unique spermidine clears 'zombie cells,' reduces inflammation, and aids NAD3®.

RESVERATROL

Helps increase NAMPT a key enzyme that plays a role in the production and recycling of NAD+

NIACINAMIDE

A form of Vitamin B3, providing an essential raw material to build NAD+
