Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.
Your contribution is essential for this service to continue to exist. We need the generosity of people like you who believe in the benefits of breastfeeding.

Vitamin B12 exists naturally in milk at a concentration of 1 nanogram / mL (Sauberan 2019; range: 0.3 to 3 ng / mL). Maternal supplementation with cyanocobalamin barely increases milk levels in well-nourished women (Sandberg 1981), but it does improve the levels in women of low socioeconomic status (Sneed 1981). The concentration in colostrum is up to 28 times higher than that of mature milk.
The daily requirements for Vitamin B12 are 2.4 micrograms (Sauberan 2019) and increase to 2.8 micrograms daily during breastfeeding. Foods rich in vitamin B12 are meat, offal, eggs, dairy products, salmon, sardines, clams and fortified cereals.
With a varied and balanced diet no vitamin supplements are needed, but B12 deficiency has been observed in the plasma and milk of women with strict vegetarian diets (vegans), malabsorptive diseases (eg, Crohn's disease, celiac disease), bariatric surgery, poor nutritional status, pernicious anemia, low socio-economic status and in cases of natural disasters or wars. There are numerous publications showing that infants of these mothers are at high risk of disease due to vitamin B12 deficiency, which can lead to anemia, stunting and psychomotor retardation.
"Flash pasteurization" applied to breast milk of mothers who are HIV+ does not decrease vitamin B12 concentration.
