What Uses Up NAD+ in the Body? CD38, PARPs and Cellular Stress Explained

NAD+ is consumed by CD38, PARPs and sirtuins. Learn how these enzymes compete for NAD+ and why this matters for cellular ageing.

NAD+ and Muscle Ageing: Why Cellular Energy Changes Matter After 40

NAD+ decline is linked to sarcopenia, age-related muscle loss after 40. Learn how NAD+, mitochondrial function and muscle ageing are connected.

NAD+ in the Brain: What Longevity Research Is Studying About Cognitive Ageing

NAD+ plays a critical role in brain energy metabolism and cognitive ageing. Learn what current research shows about NAD+, neurodegeneration and brain health.

Does Raising NAD+ Mean You Will Feel More Energy? The Science Is More Complicated

Raising NAD+ doesn't always translate to felt energy. Learn what human trials actually show about NAD+, fatigue and cellular energy metabolism.

Can You Measure NAD+ Levels? Blood Tests, Tissue Levels and What the Results Mean

NAD+ testing is more complex than a single number. Learn how blood tests, tissue studies and biomarkers differ, and what the science actually shows.

NAD+ and Sirtuins: Why Longevity Scientists Study This Cellular Relationship

NAD+ activates sirtuins, proteins central to DNA repair and metabolic health. Learn why the NAD+-sirtuin relationship is a cornerstone of longevity science.

NAD+ and DNA Repair: What Happens When Cells Experience Damage?

NAD+ powers PARP enzymes during DNA repair. Learn how DNA damage, PARP activation and NAD+ depletion are connected to cellular ageing.

What Is CD38? The NAD+-Consuming Enzyme Linked to Ageing

CD38 is an enzyme that breaks down NAD+ and rises with age. Learn how CD38 affects cellular energy, inflammation and healthy ageing.

Why Does NAD+ Decline With Age? The Role of CD38 and Inflammaging

NAD+ levels decline with age because the body may produce less NAD+, while enzymes such as CD38 consume more of it. Age-related chronic inflammation, or inflammaging, may increase CD38 activity, fu...

Beyond the Surface: The Precision Guide to Advanced Anti-Ageing Supplements

Healthy ageing starts below the surface. Learn how NAD+, CoQ10 and Resveratrol support cellular energy, resilience and long-term vitality with science-backed nutrition.
