Nicotinamide Riboside May Shield Female Mouse Muscle From Heat Damage
This early mouse study suggests NR may protect muscle from heat stress, but human data is lacking.
Heat stress can hurt muscle by triggering inflammation and damaging the cell's power plants. In female mice, the NAD+ booster nicotinamide riboside reduced that heat damage, calming inflammation and protecting mitochondria. Curiously, it worked without raising muscle NAD+ levels, so the benefit came through other paths.
