NAD+ Boosters Move the Blood Test. The Brain Test Didn't Budge.
Two 2026 trials: two supplements raised blood NAD+ (nicotinamide adenine dinucleotide, a molecule cells need to make energy) well above placebo in healthy adults, but in older adults with memory problems, 12 weeks of one of them raised NAD+ without improving memory and thinking.

Ubiquinol Didn't Boost Endurance. The Mitochondria Signal Comes From 25 Men.
In a 6-week trial in healthy young men, ubiquinol (300 milligrams a day) didn't improve time to exhaustion, the main outcome; a 25-person muscle-biopsy subgroup showed less "leaky" mitochondrial respiration, a lab marker, not a performance gain.

Laser for Neck Trigger Points: Pain Didn't Beat Sham
In a 52-person trial against a sham (fake) laser, 8 sessions of 808-nanometre (nm) laser light didn't reduce trapezius pain more than the fake one (the main outcome); a secondary neck-disability benefit was small and fragile.

Copper-Triggered Cell Death (Cuproptosis): A Study in Cells and Mice, Not a Human Treatment
A cell and mouse study, not a human treatment: in 2022, scientists showed too much copper can kill cancer cells in a new way, by jamming energy enzymes inside mitochondria. Four years on, human evidence is still thin.

Wrist Sensors in 86,772 Adults: Brighter Nights Linked to Worse Mental Health, Not Proven Cause
Adults whose wrist sensors logged brighter nights had higher odds of depression and several other psychiatric disorders in a study of 86,772 people. Brighter days went the other way. It's a link, not proof of cause.
