NMN vs NR vs IV Drips — Which Actually Raises NAD+?

Your NAD+ levels drop by roughly 50% between ages 40 and 60, starving your mitochondria and sirtuin longevity genes of fuel. In this video, we compare NMN, NR, and expensive NAD+ IV drips head-to-head, explain the hidden methyl group depletion risk, the CD38 drain plug problem, and the exact evidence-backed stack for restoring cellular energy safely. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ⏱️ TIMESTAMPS: NAD+ boosters like NMN and NR promise cellular energy, but they carry hidden risks. Learn the safe, evidence-based protocol. NAD+ levels drop significantly between ages 40 and 60, impacting mitochondrial function and sirtuin longevity genes. Comparing NMN vs NR head-to-head determines which precursor effectively restores cellular energy levels. The analysis addresses the CD38 drain that accelerates this decline and why expensive IV drips may be overrated for long-term maintenance. Beyond choosing a supplement, you must account for the risk of methyl group depletion. The breakdown covers the exact 4-part stack that includes a TMG supplement for methylation support and apigenin to block CD38, providing a complete framework for biological age management. This protocol prioritizes safety by addressing the biochemical trade-offs often ignored in longevity research.

High-dose NAD+ precursors can deplete methyl groups if not paired with TMG. Always consult a qualified physician before starting any new supplement protocol, especially if you have elevated homocysteine or methylation issues.
