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.
Verified customer reviews
I have been doing this every morning for three weeks. It fits into my routine without any friction. The orange flavor is actually good. I am sleeping better and my digestion feels more regular.
I was skeptical about a shot but after 10 days I noticed my energy feels more even through the day. Less of that heavy feeling after lunch. I ordered a second box.
I like that the ingredient list is short and every item in it has a reason to be there. My digestion has been noticeably more regular since I started. Will keep going.
No pills to count, no powders to mix. One bottle in the morning and done. My stomach feels calmer and I am not as bloated by afternoon.
The orange taste makes it easy to take every single day. After two weeks I noticed my digestion was more regular and I felt less sluggish in the morning. Really glad I tried this.
