In addition to strengthening the bones, it has other functions related to also strengthening the immune system, helping with muscle functions, and the activities of brain cells due to its anti-inflammatory, antioxidant, and neuroprotective properties.

  • Rickets (especially in infants)
  • Osteocalcin

Once you have done your test and you know for sure that you have low levels of vitamin D, it is necessary to raise these levels. But due to the state in which the patient is, great care must be taken in the doses and in how to do it.

Low levels of vitamin D during pregnancy have been associated with an increased risk of pre-eclampsia and premature delivery. But, as Nature indicates, a study was carried out between 2012 and 2016 in which more than 7,000 women collaborated and which concluded that:

  • Effectively reduces the probability of preeclampsia.
  • Reduces risk of gestational diabetes.
  • Reduces the chance that the baby will be born with low birth weight.
  • Reduces severe postpartum hemorrhage.

If you are pregnant or breastfeeding, you should not exceed 4,000 IU per day of vitamin D. Do not you take too much, you may experience nausea and vomiting, lack of appetite, weakness, constipation, and even kidney problems.

You want to raise vitamin D levels naturally, you can eat foods rich in this vitamin, such as:
