Nature just published the results of the Elysium NR+pterostilbine study of 120 healthy 60 to 80 year olds with BMIs under 30.
1) 250 mg of NR and 50 mg of pterostilbine raised NAD+ levels by 40% for eight weeks in healthy 60 to 80 year olds. 500 mg of NR and 100 mg of pterostilbine raised NAD+ levels up to 90% after four weeks but steadily lowered to 55%. (The last part is new.)
2) Liver test: ASL went down while AST decreased but not with statsitical significance. A new trial is focusing on liver health.
3) There were very slight or no changes in heart rate, blood pressure, glucose levels or triglyceryde levels for both groups.
4) “Significantly” improved mobility with a 30 second chair-stand test and a 6 minute walk test for the 500 mg but *not* the 250 mg group. Unfortunately, the extent of the physical gains was not reported.
Next up: Elysium is focusing on liver health, brain health, cardiovascular, muscular disorders and diabetes in new separate studies. The U of Colorado study is also expected to be published in a few weeks.
