Model: Older adults (60–85 years old) with mild cognitive impairment (MCI) enrolled in a randomized, double-blind, placebo-controlled clinical trial.
Dosage: Participants received one gastro-resistant capsule daily for 180 days, containing either 250 mg of Kluyveromyces fragilis yeast extract, 350 mg of Saccharomyces cerevisiae yeast extract, or a placebo.

Yeast Supplement Improves Cognitive Function in Older Adults with Mild Cognitive Impairment

Daily supplementation with nucleotide-rich yeast extracts improves cognitive performance and mental well-being in older adults with mild cognitive impairment, researchers find.

Model: 5xFAD mouse model for Alzheimer’s disease 
Dosage: Oral administration of 457 mg/kg/day of glucosamine for 2 weeks

Supplementing with glucosamine, a compound found in our cartilage, increases the risk of mortality from dementia in certain individuals while also worsening memory in mice that model dementia.

Model: Six adults who received intravenous NAD+ and eight adults who received intravenous NR
Dosage: 500 mg of intravenous NAD+ or 500 mg of intravenous NR daily for four consecutive days

Pilot Human Study Supports Safety of NAD+ IV and NR IV Infusions

A Stanford study supports the short-term safety of NAD+ and NR infusion therapies, and participants who received NR infusions exhibited significantly lower HbA1c (a blood test that reflects average blood sugar over two to three months).

A Stanford human trial provides the first data supporting the safety of NAD+ IV and NR IV therapies.

The NAD+ (nicotinamide adenine dinucleotide) precursor NR (nicotinamide riboside) counters sleep-deprivation-induced cognitive deficits in rats with excess Alzheimer’s plaques. 


GlyNAC and Exercise for Age-Related Muscle Loss: Mechanisms and Clinical Evidence

Human trials report that GlyNAC and exercise regimens improve dysfunction of the cell’s powerhouses (mitochondria), inflammation, muscle strength, and cognition.
