- A randomized placebo-controlled trial of nicotinamide riboside and pterostilbene supplementation in experimental muscle injury in elderly individuals
PubMed ID: 35998039
NRPT reliably increased blood NAD+ in elderly participants, a mechanistically relevant result for mitochondrial metabolism despite limited functional gains.
- Efficacy and tolerability of EH301 for amyotrophic lateral sclerosis: a randomized, double-blind, placebo-controlled human pilot study
PubMed ID: 30668199
Small randomized ALS trial (NR + pterostilbene) slowed disease progression and improved strength—clinical signal of cellular/neural protection.
Inflammation (1)
- Nicotinamide riboside and pterostilbene reduces markers of hepatic inflammation in NAFLD: A double-blind, placebo-controlled clinical trial
PubMed ID: 36082508
NRPT in NAFLD lowered ALT/GGT and ceramide 14:0 (markers associated with hepatic inflammation/toxicity), indicating an anti-inflammatory signal in liver.
Liver support (1)
- Nicotinamide riboside and pterostilbene reduces markers of hepatic inflammation in NAFLD: A double-blind, placebo-controlled clinical trial
PubMed ID: 36082508
In adults with NAFLD, NR + pterostilbene lowered ALT/GGT and reduced a toxic ceramide species despite no change in hepatic fat fraction.
Antioxidant (1)
- A Short-Term Safety Evaluation of Silbinol(®)- an Extract from Pterocarpus marsupium in Healthy Adults- a Randomized, Double-Blind, Placebo-Controlled Study
PubMed ID: 37671486
Randomized 200 mg/day pterostilbene trial showed a modest (~11%) increase in blood glutathione (GSH), an antioxidant marker.
Brain health (1)
- Efficacy and tolerability of EH301 for amyotrophic lateral sclerosis: a randomized, double-blind, placebo-controlled human pilot study
PubMed ID: 30668199
ALS pilot (NR + pterostilbene) showed clinically meaningful slowing of neurological decline and improved strength/respiratory function—strongest direct neuro benefit in dataset.
