NR Nicotinamide Riboside: Effective Antivitamin Supplement or Hype?

Regarding antioxidant effects, there are three main categories of natural antioxidants in plants: phenols, carotenoids, and vitamins. Among them, phenolic compounds in a broad sense refer to a type of aromatic compounds in which the hydrogen on the aromatic hydrocarbon ring is replaced by a hydroxyl group, including not only polyphenols and phenolic acids, but also compounds containing phenolic hydroxyl structures such as flavonoids and stilbenes. The potential antioxidant capacity of plant raw materials mainly depends on the type and content of phenolic compounds in the plant or its extract. In addition, there is a synergistic effect of some polyphenols and/or other antioxidant components in certain plants or their extracts, resulting in powerful antioxidant activity.Today, plant extracts have become a source of inspiration for scientific research in cosmetics. After the components of the extract are identified, some functional molecules are isolated separately and used as cosmetic raw materials. Many functional molecules that are popular on the market are derived from plants, such as salicylic acid from willow, resveratrol from knotweed and grapes, astaxanthin from algae, etc.
