When it comes to NAD+ supplements, it’s not just what you take — it’s what your body actually absorbs. Here’s why NAD+ bioavailability is the key to energy, focus, and longevity.
What is bioavailability?
Bioavailability describes how much of a supplement your body can actually use. For NAD+, this makes a huge difference. You could take the highest dose of a capsule — but if it only absorbs 10–20%, your cells don’t get the real benefit.
Why NAD+ matters for energy and performance
NAD+ is a vital molecule found in every cell. It powers energy production, supports repair, and helps maintain youthful function. But natural levels decline with age. That’s why many people look to supplementation — the challenge is making sure it’s effective.
Different delivery methods, different results
- Oral pills (NR/NMN): Easy to take, but variable absorption due to digestion and liver breakdown.
- IV drips: Highly effective but invasive, time-consuming, and costly.
- Subcutaneous NAD+ Pen: Bypasses digestion, offering high absorption and convenience from home.
What higher absorption means for you
For busy professionals and health-conscious early adopters, high bioavailability means you’re actually getting the promised energy, focus, and recovery. That’s why choosing the best NAD+ delivery method is so important.
