NAD+ for energy levels

I started taking NAD+ after I stopped breastfeeding my baby and I found it made a huge difference to my overall energy levels. After feeling a depletion in energy levels postpartum I noticed immediately after starting NAD+ that my energy is far more sustained during the day and my ability to focus is much improved, My brain fog has vanished which helps to manage working and family life better. My hair and skin look and feel healthier. The NAD+ kit is super user friendly and help is on hand from the team if you have questions. I can't recommend Holte enough if you're looking improve your overall wellbeing long term. A real a game changer - I've tried all the supplements under the sun and nothing comes close in terms of results.

Love it, so convinient!

I’ve been using the Holte NAD+ Pen for a few months now and honestly, I’m really loving how easy it is to fit into my routine. I was curious about NAD+ because of all the talk around energy, recovery, and healthy ageing, but what sold me was how simple Holte made the whole thing. The pen is sleek and super convenient, and the refill cartridges make it so easy. Since I started using it, I’ve noticed my energy feels more steady throughout the day and I bounce back quicker after workouts. It’s not some crazy overnight transformation, but more of a consistent, subtle boost that makes you feel like your body is running a bit smoother. If you’re into wellness I highly recommend it!

My partner bought me the NAD+ Pen…

My partner bought me the NAD+ Pen Starter Kit for Christmas and I feel a massive difference already. Taking a slightly higher dose than Holte recommend and taking it everyday. My partner uses their vials which are great value. Highly recommend.

I started taking NMN to improve…

I started taking NMN to improve physical performance and recover, which I’ve started to find more difficult as I age. I took NMN pills for 11 months without noticing any real difference.

In December bought a Holte NAD+ Pen Starter Kit. The change has been amazing. Can really feel it when working out and just generally with better energy and focus. The most surprising benefit is it seems to reduce/ stop hangovers. Very useful over Christmas.

Creaking Ultra marathoner - injury cycle broken

Thanks to the guys at Holte, who gave great support with prompt advice, product info and personalisation, I've been able to arrest a cycle of slow and chronic aches, immobility and pain following admittedly overzealous training with subtle aging. Product has allowed the tough love of training to be built upon, joints mobilised and soft tissues recovered; with young children and a downward spiral, previously there were more enforced rest days than efforts. Thanks for jump-starting my fitness again.

Real difference maker

My job can be full-on and I usually feel drained by the end of the week. Since using the NAD+ Pen I’ve noticed I’ve got more focus and I’m not as wiped out in the evenings. It’s made a real difference.

A game-changer for perimenopause symptoms

I’m in my mid-40s and really struggled with the symptoms of perimenopause – low energy, mood swings and just not feeling like myself. Since starting NAD+ injections, I’ve felt so much more balanced and able to cope with everyday life again. It’s honestly been the only thing that’s made a real difference for me. I’d highly recommend Holte to anyone going through this stage of life.

NAD+

I hadn't heard of NAD, but a friend who swears by it convinced me to give it a go. I'm in my mid-sixties, fairly active but suffer from autoimmune issues. I've just grown used to my energy levels fading and had written off that changing. I honestly can't believe the difference. When using the nad pen, I feel like me a good day. Most surprisingly, the daily pain from my arthritis has noticeably improved, which has been a wonderful bonus. I reside in Spain for some of the year, and the travel case is great and keeps the pen cooL

Bought refill NAD cartridges on…

Bought refill NAD cartridges on subscription. Much better value than the two brands I previously used for exactly the same results. The cartridges also fit my old pen. Delivery and packaging also superior.

Already feeling the benefits!

Already feeling the benefits after three weeks of use. Eczema has improved and energy levels are better even though I have a one year old! I was a bit nervous about using the pen but it’s really easy! Great product. I’m a covert.
