Snake oil
According to the experts that we spoke to, the death, which followed an intravenous NAD⁺ infusion that went catastrophically wrong, underscores the risks of unproven treatments and the need for rigorous longevity medicine. Earlier this week, Elizabeth Baron, a 27-year-old woman from New York City, died after receiving an intravenous infusion at a local “wellness...
Situps
A new study suggests that regular planned exercise, not just being generally active, protects against certain aspects of muscle aging [1]. Are trained muscles younger? With age, skeletal muscles lose strength, metabolic flexibility, and mitochondrial capacity. While regular exercise slows many aspects of functional aging [2], just how deeply training affects the molecular state of...
Drug combination
Researchers have found that simultaneously supplying NAD+ through NMN and reducing its loss through apigenin restores muscle function and bone structure to aged mice. A well-documented issue NAD+ is one of the most well-documented compounds in biology, including within the context of aging. Precursor supplementation has been repeatedly documented to have measurable benefits; for example,...
DNA Closeup
A new study reveals a surprising mechanism that might be behind the beneficial effects of NAD+ in preclinical models of Alzheimer's [1]. Which way to splice it? Not every part of a DNA sequence gets translated into a protein. Each sequence consists of exons, which are included in the final RNA transcript, and introns, which...
Brain proteins
In Nature Aging, researchers have described how an increase in the iron-associated protein ferritin light chain 1 (FTL1) is related to age-related cognitive impairment. Impairment without cellular death While neuronal loss is always a concern, age-related cognitive decline has been found to be primarily driven by other factors, such as synapse function [1]. Only a...
Nicotine
A recent study reported that long-term nicotine consumption had a positive impact on motor function in male mice. The beneficial effects were mediated by sphingolipid and NAD+ metabolism [1]. Two faces of tobacco smoking Smoking tobacco is widely considered detrimental to health for multiple good reasons, as it has been associated with increased risks of...
