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.

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.

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.

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.

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

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.
