Finding Your Sweet Spot: How Much NAD+ Should You Take?
Last Updated: 12 January 2026

What is the correct dosage for NAD+? There is no "one size fits all" dose. Most users inject 15 units on the NAD+ pen. This indicated a 50mg dose. We recommend using your pen once a day for three days, then continuing every other day.
Key Takeaways
Start Every Day: Start your injections once a day for three days, then continue injecting every other day.
The "Sweet Spot": We recommend injecting 15 units on the Vivere pen. This is a 50mg dose.
Consistency Wins: Sticking to your routine encourages the best results.
Phase 1: First Three Days
Your first three days are about introduction, not saturation. This involves injecting 15 units on the Vivere pen for the first three days.
Phase 2: Every Other Day
After the first three days of use, we recommend injecting the same dose (15 units/50mg) every other day moving forward.

Why "More" Isn't Always Better
It is tempting to think: If 50mg is good, 100mg must provide twice the benefits.
Finding your sweet spot isn't about taking the most NAD+ possible. It's about taking the exact amount your body can use. Our recommended dose ensures that you get the maximum benefit whilst maintaining safety.
Listen to Your Body
Your "Sweet Spot" might be different from your partner's or your friend's. It depends on your age, your weight, and how depleted your natural NAD+ levels were when you started [1].
