Very Low Risk
Retinol or vitamin A is a natural component of breast milk. It contains about 750 μg/L (1 μg = 1 mcg = 1 microgram = 3.33 IU of Vit. A).
The daily needs of the infant are 400-500 μg and in the nursing mother 1,200-1,300 μg (NIH 2018, Ares 2015, Hall 2010).
Doses of more than 3,000 μg daily (10,000 IU) should be avoided in the nursing mother (NIH 2018). There is a risk of serious poisoning with isolated doses of 25,000 IU and chronic doses of 5,000 IU per day.
Vitamin A is widely distributed in animal and plant foods. Except in certain nutritionally deficient populations, with a varied and balanced diet, vitamin supplements are not necessary in most women.
Vitamin A deficiency leads to xerophthalmia, anemia, growth retardation, and increased infectious morbidity and mortality (Sommer 2002).
In regions with serious socioeconomic problems, there is a high prevalence of vitamin A deficiency (Souza 2012, Ahmed 2003).
There is no conclusive evidence that the administration of mega doses (200,000 - 400,000 IU) of postpartum vitamin A is effective in reducing maternal or infant morbidity and mortality (Oliveira 2016, Grilo 2016, McCauley 2015, Fernandes 2012, Gogia 2011 and 2010) or that it reduces the risk of mother-to-child transmission of HIV (Wiysonge 2017) and may increase the risk of HIV transmission and mastitis in HIV-infected mothers (Villamor 2010, Arsenault 2010).
Administering mega doses of vitamin A increases the colostrum concentration of vitamin A but reduces that of alpha-tocopherol or vitamin E (Grilo 2016 and 2015).

We do not have alternatives for Vitamin A since it is relatively safe.
