How it works
Riboflavin serves as a precursor to flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN), essential cofactors for numerous enzymes involved in cellular respiration and energy production within mitochondria. Adequate levels are necessary for the proper functioning of the electron transport chain and ATP synthesis.
Who should take it
Adults looking to address brain fog, memory decline, attention difficulty. Particularly relevant for people who prefer a targeted single ingredient and who have ruled out an underlying condition that needs medical care first.
