How NAD+ injection works

Powers Cellular Energy

Produces energy, helping you feel more vibrant, focused, and alive.

Supports DNA Repair

Keeping your cells healthy and slowing the effects of aging.

Optimizes gene expression

Boosting metabolism, reducing inflammation, & promoting vitality.

NAD+ naturally declines as you age

Why do we need NAD+?

NAD+ is a natural molecule your body relies on to create energy, repair cells, and keep your brain sharp. But as we age — or just go through stress, busy schedules, or poor sleep — those levels drop. That’s when you start to feel it: sluggish mornings, afternoon crashes, and that lingering brain fog. NAD+ injections help refill your energy tank from the inside out. Instead of a quick caffeine spike, it’s a deeper, cleaner boost that helps you feel steady, focused, and more alive throughout the day.

Testimonials

Join our customers in feeling their best

Lifinity felt like the Apple of longevity. Everything from the online intake to the delivery was seamless. I liked how clear the instructions were and that I could actually talk to a real person. I’ve already recommended it to two colleagues.

New York

Clean, modern, and honestly kind of badass. I loved that I could start with capsules and upgrade later. It didn’t feel pushy, just empowering. I’ve never stuck with a health routine longer than 2 weeks, and now I actually look forward to it.

David R., 36

Miami

My skin feels brighter. My eyes don’t look as tired. I don’t know how to explain it scientifically, but my face looks more alive — and I feel that way inside too.

Michael S., 47

Denver

I was nervous about trying anything involving injections, but Lifinity made me feel safe and supported the whole way. Their care team was responsive, kind, and genuinely wanted to help me feel better. It didn’t feel transactional — it felt personal.

Jessica M., 48

Oregon

I used to crash hard around 2pm and reach for a second coffee. Since starting Lifinity, my energy feels more stable — like my battery lasts longer. It’s subtle but powerful.

Amanda L., 39

It’s like my brain went from dial-up to fiber optic. I feel sharper at work, more articulate, and even my mood’s more stable. Lifinity gave me back my edge.
