2019: A 3-month RCT of 280 women with PCOS found 3 g L-carnitine improved menstrual cycle regularity and ovulation/pregnancy rates, but miscarriage rates did not differ [3][50]
Acetyl-L-carnitine increases energy levels and improves cognitive abilities
Thus, ACs play a critical role in mitochondrial energy metabolism, essential for functioning of all tissues, as they transport long-chain fatty acids into mitochondria for -oxidation, a key energy production process [13]
Remarkably, elevated homocysteine levels have frequently been associated with poor oocyte maturity, reduced fertilization and poor in vitro embryo quality 95 , though direct clinical evidence linking riboflavin, homocysteine and anovulation is sparse
As NAD+ levels decrease with age, this can lead to reduced DNA repair, cellular stress response and regulation of energy metabolism
