Brief Summary
This research project aims to determine whether supplementing with a mixture of the NAD+-precursors NA, NAM, and tryptophan can stimulate skeletal muscle mitochondrial function in physically compromised, elderly humans. Outcomes are related to mitochondrial function, energy metabolism, and physical function will be investigated.

After 4 weeks of supplementation.
Submaximal exercise energy expenditure
Submaximal exercise energy expenditure expressed as kcal/kg/min
After 4 weeks of supplementation.
Secondary Outcomes (4)
Glucose tolerance
After 4 weeks of supplementation.
Ectopic lipid accumulation
After 4 weeks of supplementation.
Acetylcarnitine levels
After 4 weeks of supplementation.
Physical function
After 4 weeks of supplementation.

Intervention
ACTIVE COMPARATORControl
PLACEBO COMPARATORInterventions
Intervention product containing the NAD+-precursors nicotinic acid, nicotinamide, and tryptophan (total of 204 NE per serving) in a whey protein source for 31 days.
Control product containing amino-acid mixture resembling whey-protein not containing the NAD+-precursors nicotinic acid, nicotinamide, and tryptophan. To be taken for 31 days.
