NMN and aging

NAD+ levels decline as we age. There is some evidence from studies in model organisms that restoring NAD+ levels can increase lifespan/healthspan. One way to restore NAD+ levels is through NMN supplements, which is a precursor to NAD+. In this video, I will go into more detail regarding this and also look at why it could be beneficial and when are the potentially best times for NMN to be taken.

Marine macroalgae: A source of chemical compounds with photoprotective and antiaging capacity

Abstract

The biological effects of ultraviolet radiation (UVR) on the skin have been known for years, which is why there has been an increase in the use of sunscreen products, whose purpose is to protect the skin from these effects through the action of sunscreens that absorb, disperse, or reflect radiation.

Sunscreens contain sun filters that act to protect human skin from the harmful biological effects of UVR. However, due to problems related to the effectiveness and safety of sunscreens in recent years, we have resorted to the search for potential photoprotective molecules from natural sources, among which are marine macroalgae which in turn are a source of molecules with potential antiaging effects.

The present review shows the current state of sun filters, the mechanisms that trigger aging, and several compounds present in marine macroalgae with photoprotective and antiaging capacity with potential use in cosmetic products.
