SAVE10 auto-applied at checkout—expires Sept 30.1. What is NAD⁺ & why does it crash after 30?
NAD⁺ (nicotinamide adenine dinucleotide) is the cellular currency that fuels >500 reactions including ATP synthesis, DNA repair (PARP), gene silencing (sirtuins) and immune signalling (CD38). By age 50 average levels drop ≤65 % versus age 20, leading to afternoon brain-fog, slower 5k times and longer DOMS.
2. How EnduNAD boosts NAD⁺
- Precursor load – 250 mg NMN + 50 mg NR → rapid NAMPT conversion.
- Salvage-pathway support – B3, B6, magnesium → blocks methylation burn-out.
- Sirtuin activation – 100 mg trans-resveratrol + 50 mg quercetin → ↑ SIRT1 3.1-fold.
- Mitochondrial biogenesis – 100 mg CoQ10 + 150 mg ALA → ↑ PGC-1α.
- Antioxidant shield – 150 mg EGCG + 50 mg apigenin → ↓ 8-OHdG 18 % in 30 d.

4. Synergy map—why 1+1=3
- NMN ↑ NAD⁺ needs methyl donors → B3, Mg provided.
- Resveratrol ↑ SIRT1 needs NAD⁺ as co-substrate → supplied.
- CoQ10 ↑ electron flow → ALA regenerates CoQ10.
- EGCG ↓ inflammation → prevents COX-2 inhibition of NAMPT.
- Bioperine ↓ glucuronidation → resveratrol bioavailability +54 %.
Net: 2.7-fold higher NAD⁺ rise vs NR alone (Pharo Study 2024).

10. How to cycle & stack
8-week beginner cycle
- Week 1-2: 1 cap AM, 16:8 fast, 3×30 min zone-2.
- Week 3-4: 2 caps AM + 5 g creatine + 2 g taurine.
- Week 5-6: 2 caps, 2×HIIT + 1×ruck.
- Week 7-8: Add 500 mg glycine + 400 mg Mg glycinate pre-bed → HRV ↑.
