REAL Science Behind NAD+ | Precursors & IVs Fail Without This Step l Courtney Van Bussum l Ep #418

About this video

Niddam interviews Courtney Van Bussum about why simply raising NAD may be an incomplete longevity strategy. Van Bussum argues that cellular health depends on balance between related redox forms, functioning salvage and recycling pathways, and control of enzymes and inflammatory stressors that consume NAD. They discuss why, in her account, precursors and direct NAD delivery methods can fail without that upstream context, and introduce a lesser-known metabolite involved in regulating NAD breakdown. The episode also teaches listeners to interrogate study funding, design, and marketing claims, and closes by emphasizing nervous-system regulation and foundational habits alongside any NAD-focused product.

Key takeaways

• Balance within a pathway is presented as more important than maximizing a single molecule
• A supplement failing to raise a marker may reflect pathway bottlenecks, not just product quality
• Checking who funded a study and how it was designed is offered as a basic literacy skill
• Inflammation and stress are framed as drivers of nutrient depletion, not background noise
• Foundational regulation and lifestyle are presented as prerequisites, not alternatives, to advanced tools
