What changes in 3 months
No big routine. One small shot, twice a week. Here is what women noticed by month 3.
The afternoon slump eases off. You get through the day on your own fuel, not your third coffee.
Skin looks smoother and more rested. The fine lines that show up in photos start to soften.
In our 3-month clinical study with Citruslabs, women's blood tests came back showing a younger biological age. Not a feeling. A result.
One small shot, twice a week. Sixty seconds, tastes good, no pills to swallow.
The receipts
Citruslabs designed and ran the trials independently. A board-certified dermatologist scored the photos blind. An outside statistician confirmed nothing here is chance.

"When half of women drop their biological age in 3 months, you stop calling that a feeling. You call it measurement."
Inside the bottle
Most NAD+ products give you NAD+ on its own. We paired it with resveratrol-enriched yeast, rice ceramides and a fruit antioxidant family. The combination is the formula women drank in our Citruslabs trial.
Nicotinamide riboside (NR), the form your body turns into NAD+, plus resveratrol to back it up. This is the energy part.
Rice-seed ceramides. Natural skin lipids that help keep skin smooth and support a healthy skin barrier.
White Versailles currant plus a botanical family of blood orange, spinach, grape seed and red wine. Polyphenols that help protect cells from oxidative stress.
Plus 18 calories per bottle. Zero added sugar. Made in the USA.
The routine
The recommended cadence for steady NAD+ support without overthinking it.
Step 01
Shake the bottle. The botanicals settle because there are no fillers holding them in place.
Step 02
Drink it straight. Cold over ice or at room temperature. Chase with water if you like.
Step 03
Pick two days that stick to your week. Stay with it for 3 months. That is when the numbers in our clinical trial moved.

I've been using the Longevity Shot for a few weeks and I love the results. My skin feels more hydrated and the fine lines are less visible. I feel more confident!
I've been taking NAD in capsule but nothing gives me the energy boost of these shots. I felt it in the gym the very same day!!
I couldn't recommend the longevity shots more. I've been taking it for 5 months now and I have so much more energy! It also tastes great and so much better than taking lots of pills
I started using the Longevity Shot a month ago and I already see differences. My energy has increased and my skin feels firmer. It's great to find something that really works!
After just two months of taking this, I've already noticed a big difference in my energy and skin. I've been getting so many compliments — it's a total game changer and tastes amazing!
