Alfa-ketoglutaarzuur
Het nieuwe anti-agingsupplement?

Kan suppletie met alfa-ketoglutaarzuur (AKG) de levensduur van de mens verlengen? Recentelijk uitgevoerde studies met wormen en muizen ondersteunen deze hypothese. Ook zijn er enkele onderzoeken bij mensen gepubliceerd die wijzen op potentiële gezondheidsvoordelen van AKG. In dit artikel een overzicht van de invloed van AKG op het verouderingsproces, de gevolgen van de natuurlijke afname ervan op de gezondheid en de wetenschap achter suppletie voor een lang en gezond leven.
