Amino Acids in Prenatal Supplements


Among its numerous properties, L-Carnitine has been shown to:

  • Increased progesterone in the luteal phase
  • Lead to greater endometrial thickness
  • The free radical scavenging effect of L-Carnitine and subsequent effects on the endometrial blood flow, ultimately support healthy endometrial receptivity in the Peri-implantation phase of pregnancy


An essential amino-acid, L-Arginine is a key player in a number of physiological functions. The main one, which is absolutely essential for conception, is the regulation of blood circulation redirected to the genitals, uterus and ovaries. The supply of oxygen-rich blood is one of the most important elements in reproductive health. L-Arginine in summary, is a key ingredient of PregnaluX for the following reasons:

  • L-Arginine may improve the chances of successful conception. Heightened blood flow in the uterus creates a better environment to allow the implantation of a fertilized egg, whilst better blood circulation in the ovaries, allows for optimal egg production
  • L-Arginine improves the production of cervical mucous
  • L-Arginine prevents uterine fertility issues, e.g. fibroids, endometriosis and PCOS. Inflammation is well known to negatively impact conception and implantation
  • L-Arginine helps with increased blood flow to the genitals, which can lead to increased sexual arousal and orgasm. Don’t forget: A healthy libido plays an important role in conception

L-Carnitine in PregnaluX - Carnipure

Because we believe in the importance of this ingredient, Supplemena uses Swiss-made L-Carnitine, in all of fertility supplements. This trademarked Swiss ingredient is called Carnipure, and we believe it's one of the best things about our supplements.

There is increasing evidence that L-Carnitine may play an important role during pregnancy, particularly in women following a meat-reduced or vegetarian diet for which daily L-Carnitine intake may be too low to meet the increased needs during pregnancy. Due to its excellent safety profile, Carnipure® supplementation may be appropriate for pregnant women to restore their L-Carnitine plasma levels and at the same time decrease plasma free fatty acids. Of course, pregnant women should always consult a physician before taking any dietary supplement. The studies below explain the role L-Carnitine plays to benefit pregnancy-related changes in L-Carnitine metabolism, the role it plays for the placenta, and its effects on lipid metabolism and glucose levels.
