A small study finds that hyperbaric oxygen treatment increased immune cell telomere length and reduced cellular senescence, two important markers of aging.

Glucosamine is often used to alleviate joint pain and osteoarthritis symptoms. A recent study found that chronic glucosamine use is linked to a 15% reduced risk of all-cause mortality.

NAD+ precursors restored low NAD+ levels in people with short telomeres, mitigated mitochondrial and telomeric DNA damage, restored sirtuin and PARP activity, and delayed cellular senescence.

A study of hair regrowth found that microRNA from dermal exosomes successfully regenerated hair in mice, which could be a candidate for non-invasive hair regrowth creams or microneedle patches.
