L-Carnitine is present in very high concentrations in follicular fluid and mature oocytes, where it plays an essential role in transporting fatty acids to the mitochondria to produce the energy needed for oocyte maturation and early embryonic development. It also protects oocytes from oxidative stress by acting as a natural antioxidant, thereby reducing oocyte DNA fragmentation and improving egg quality.
Recent meta-analyses and trials confirm these effects: after 2 to 3 months of L-carnitine supplementation, the oocyte maturation rate increases by 10 to 25%, the fertilisation rate by 8 to 18%, and the rate of good-quality blastocysts by 12 to 30% compared to placebo, with particularly marked benefits in women over 35 and in cases of poor ovarian response.¹
That is why our medical formulators have included L-carnitine in +fertiwomen at the optimal dose: safe, effective daily support with no side effects, working in perfect synergy with ubiquinol and the other active ingredients in the formula to maximise your chances of natural conception.
