Minimal risk for breastfeeding and infant.
An amino acid component of proteins.
Found in meat, fish, dairy products, nuts and seeds (AESAN 2012). It stimulates the production of nitric oxide (vasodilatory) and the release of insulin and growth hormone.
It is indicated in states of deficiencies due to states of high catabolism or a very protein deficient diet. Most of its attributed therapeutic properties are not well-proven (MedlinePlus 2012, AESAN 2012). It is used in diagnostic tests for growth hormone (Biomed 2009).
It is found naturally in breastmilk at a higher concentration in colostrum than in mature milk (Lawrence 2016 p.766, Bjelaković 2010).
Since the last update we have not found published data in relation to breastfeeding.
Although an excess of amino acids or proteins in the diet can increase plasma levels, the concentration of proteins and other components of the milk is regulated in the epithelial mammary cell and is very independent of the plasma concentrations.
It has been used to prevent necrotizing enterocolitis in premature infants (MedlinePlus2012, Lee 2011, Thompson 2008).
It has a high safety profile, with no adverse effects observed at the recommended doses. A maximum daily intake of up to 3g (AESAN 2012) is advised.
Its moderate and non-abusive consumption is probably harmless during breastfeeding.
We do not have alternatives for L-Arginine since it is relatively safe.
