Vitamin D For Breastfeeding Mothers

Breastmilk is a rich source of all the necessary nutrients that your baby needs during the first 6 months. But, if the breastfeeding mother lacks a specific nutrient or suffers from malnutrition, then the child also grows with the same deficiencies. This eventually results in underdeveloped physical or mental conditions. Vitamin D is one such nutrient needed for the baby in huge quantities just from the beginning. But the breastmilk often cannot supply it enough. This article takes you through the necessity of Vitamin D for breastfeeding mothers and how much they need it.

Our body largely depends on sunlight for the absorption of vitamin D. If you belong to the region between the Equator, the tropic of Cancer, and the tropic of Capricorn then you are not likely to have vitamin D deficiency. But people living in cold regions or people who do not go out much in sun can have this problem. Your little one needs vitamin D to develop strong bones and teeth. This article can help you on getting an idea about the importance of vitamin D, and the amount of it you need while breastfeeding.

What is Vitamin D?

According to the Harvard school of public health, Vitamin D is both a nutrient we consume and a hormone our bodies produce. This vitamin is necessary for our body to absorb and retain phosphorus and calcium. So in this way vitamin D helps our bones to form and get stronger. Vitamin D has also a significant role in reducing infections, and inflammations.

Sunrays are the source of vitamin D for our skin. A mere 10 to 15 minutes of exposure to sun rays is sufficient to meet the daily vitamin D requirements for people. But, as strong sunlight can potentially cause sunburns, people tend to avoid it specifically for their babies. In that case, vitamin D supplements come to the rescue.

People who live in cold regions do not get enough sun exposure and are prone to vitamin D deficiency. On the other hand, eating fatty fish like salmon or mackerel daily for vitamin D is not good for health. In such situations, you should consider taking supplements.

Studies show that there was a significant increase in vitamin D levels in breastfeeding babies when the mother is on supplements. But you must take your doctor’s advice and take only the prescribed doses of vitamin D supplements.

You can even give vitamin D supplements to your baby directly. As per the AAP 2008 guidelines, even doctors now suggest providing babies with vitamin D supplements as only breastmilk is not enough to meet the daily requirements.

You can put the liquid on the tongue of your baby with the help of a dropper. If that doesn’t help then you can mix it with some of your pumped breastmilk and let your baby drink it. Various vitamin D supplements taste different. So you can try different brands if your baby is not liking the taste of a particular brand’s supplements.

Are There Any Side Effects of Excessive Intake of Vitamin D?

Though vitamin D is very important for our body, an excessive amount of it can be harmful. This condition is called Hypervitaminosis D. The side effects of excessive vitamin D in your body are:

  • Hypercalcemia or the building up of calcium in the blood
  • Nausea
  • Vomiting
  • Frequent urination
  • Calcium stones in kidney or kidney stones
  • Bone pain
  • Weakness

The problem of excessive vitamin D occurs when you take vitamin D supplements beyond your prescribed limits. It cannot occur due to excessive sun exposure. To cure Hypervitaminosis D, your doctor then will stop the vitamin D supplements and restrict your dietary calcium.

So, taking prescribed vitamin D supplements while breastfeeding is the best way you can protect your baby from vitamin D deficiency. A well balanced diet can also help you attain the right amount of Vitamin D. However, it is better to get an appointment with your doctor if you are too concerned. Talk to your them to understand the importance of Vitamin D during breastfeeding.
