infusions
What NAD infusion studies actually measure
Blood chemistry can establish exposure. It takes a different study to establish a meaningful benefit.
From Adrian Vale
precursors
NR versus NMN: compare the trials before the molecules
Study populations and endpoints explain more than a simple precursor leaderboard.
biomarkers
Does a higher NAD result mean better health?
A responsive biomarker is useful evidence, but it is not a validated promise of benefit.
fatigue
NAD and fatigue: what has actually been tested?
Everyday tiredness, drowsiness and a diagnosed fatigue condition are different research questions.
exercise
NAD supplementation and exercise: measure performance, not just chemistry
Ventilatory thresholds, peak capacity and daily function tell different stories.
formats
Oral, injected or infused: what NAD research can compare
Different molecules and routes require separate evidence, even when the marketing uses the same initials.
safety
How human NAD studies report safety and tolerability
A small trial with few reported events cannot establish safety for every product or long-term user.
testing
Can a consumer NAD test choose your supplement?
Analytical measurement and evidence that testing improves a decision are different standards.
