Red and infrared light
Red and infrared light support mitochondrial function and skin resilience.
Strong consensus“the red spectrum of light penetrates into the mitochondria kicks nitric oxide off and then the electrons can flow through”
Nicotinamide riboside
Nicotinamide riboside is a promising NAD+ supplement, but balance with methyl donors matters.
RecommendedFor nad+ supplementation.
The strongest voice
“always take it with meals... your meal is going to boost your energy levels, and your energy levels in the form of ATP are going to help drive that niacin riboside into synthesizing NAD”

One faithful sentence per source, linked to the moment it was said; quiet chips mark where money is involved.
a nutritional sciences PhD recommend
“More data exists on NR compared to NMN, making it preferable for supplementation.”

Infrared light therapy
Infrared light therapy is widely valued for supporting mitochondria and relaxation.
Strong consensus“infrared light which can penetrate 8cm into the body can help to clear this out of the way so that your mitochondria can carry on making ATP and water”
Infrared exposure
Infrared exposure helps support healthy blood flow and cellular energy production.
Strong consensus“The main things are sunlight exposure, infrared light, anything that's going to build charge in your body is going to help build the structured water and that’s going to prevent this clotting response.”
