Resveratrol Prevents Skeletal Muscle Atrophy and Senescence

Resveratrol (RSV) is a natural polyphenolic compound with antioxidant, anti-inflammatory, and anti-senescence and antitumor effects.  A new study investigated the effects of resveratrol (RSV) on cigarette smoke (CS)-induced skeletal muscle atrophy and cellular senescence in mice.   Thirty-two male mice were randomly divided into four groups: the control group (N), the resveratrol group (RSV), the emphysema […]

Increasing NMN Transporter in the Brain Reduces Age-Related Muscle Decline

A new study shows that increased levels in the brain of a molecule called Slc128a, which transports NMN into cells, reduces a type of muscle decline in older adults called sarcopenia. Likewise, they showed that reducing levels of Slc128a in the brain caused the muscles to become fatigued and weakened again. Doubling Slc128a Dramatically Improved […]

Heart Disease Related to Accumulation of DNA Damage and Oxidative Stress

As we age, the risk for clogged arteries, brittle blood vessels, and heart failure increase. A recent study looking at the DNA in numerous individual heart cells tells the story of why this occurs Buildup of Damaged DNA and Faltering Ability to Repair Damage In a ground-breaking study spanning 0 to 82 year olds, they […]

NAD+ and the Hallmarks of Aging Series – Part 9: Altered Intercellular Communication

Intercellular communication: communication between cells All species of animals, including the human being, are multicellular organisms (an organism that consists of more than one cell). In order to work collectively and maintain the homeostasis across multiple tissues, our cells have developed multiple different ways to receive, process, and transmit information between each other, including endocrine, […]

Newly Found Benefits of Resveratrol in Health and Anti-aging

Resveratrol is a polyphenol derived from plants with antioxidant properties that have been shown to enhance the activation of the body’s own self-repair proteins, called sirtuins. When sirtuins are activated, the effect is delayed aging, which has been demonstrated in a wide spectrum of experimental models, including mammals.

Trimethylglycine (TMG) for Restoring Methylation, Homocysteine Levels, Heart Health, and Liver Function

TMG – the Insurance Policy Against Loss of Methyl Groups TMG is one of the most important ways to restore methyl groups because as the name implies, it has three methyl groups to donate. “The reason I take glycine, specifically trimethylglycine is to counter what I think may be going on with an NAD+ booster”… […]

NAD+ and the Hallmarks of Aging Series – Part 6: Mitochondrial Dysfunction

Mitochondria – More than Powerplants in Cells Mitochondria are the large organelles that exist in most human cells. They are the critical organelles that generate ATP through the respiratory chain and produce the intermediate metabolites that are essential to various cellular processes.  During aging, the respiratory chain losses its efficacy and the membrane of the […]

Reduced Nicotinamide Mononucleotide – A Tale of Four NAD+ Precursors

NAD+ Precursors and Healthy Aging Nicotinamide adenine dinucleotide (NAD+) is a coenzyme found in all living cells. It is a critical coenzyme for energy metabolism and also serves as the substrate for enzymes such as the sirtuins. One of the hallmarks of aging is declining cellular NAD+ levels.  Moreover, many studies carried out in different […]

NAD+ and the Hallmarks of Aging Series – Part 5: Deregulated Nutrient Sensing

Overview Currently, available evidence strongly supports the idea that anabolic signaling (the signal that promotes growth and proliferation) accelerates aging, and decreased nutrient signaling extends longevity (Fontana et al., 2010). Further, a pharmacological manipulation that mimics a state of limited nutrient availability, such as rapamycin, can extend longevity in mice (Harrison et al., 2009). In […]

Bacteria in Gastrointestional Tract Metabolize NMN and Impact NAD+ Metabolome

This recently published research by Drs. Lindsay Wu, David Sinclair and others examined the pathways that oral NMN takes to becoming NAD+ in mice. It confirmed some aspects of earlier research, and also made some surprising new findings. https://assets.researchsquare.com/files/rs-87047/v1_stamped.pdf Several experiments were completed that all measured NAD+ metabolites in the Gastrointestinal Tract (GIT) and Liver, […]
