Vitamin B7 During Pregnancy

The good news of your positive pregnancy test is topped up with a lot of responsibilities. You need to take a little extra care of yourself and for the little bundle of joy that is arriving soon to be your family member. You might be a healthy eater, but you may also need to fill your plate with supplementary prenatal nutrients. The body needs an extra dose of everything for that little life growing inside during pregnancy. This includes many macro and micronutrients as well. Biotin or vitamin B7 is one of them. In this article, we discuss the need for Vitamin B7 during pregnancy.

A pregnant woman might face certain vitamin deficiencies as the body goes through a lot of hormonal imbalances. As your body prepares to accommodate a new life, it needs sufficient nutrients in aiding a healthy pregnancy. Nutrients that we get from our daily diet may not be enough to nurture two lives. That is why doctors prescribe supplements during pregnancy. Certain sets of B vitamins or B complex vitamins are also necessary during pregnancy. A set of eight water-soluble vitamins are categorized under the B complex, one of them being vitamin B7.

What is Vitamin B7?

Vitamin B7 or biotin is one of the micronutrients that aid in healthy metabolism. It is a water-soluble vitamin. Water-soluble vitamins cannot be stored in the body and hence require a regular intake. Biotin acts as a part of enzymes and helps in breaking down fats and carbohydrates through which the body metabolism increases. Excess biotin can come out through urine and faeces since B complex vitamins are water-soluble.

The B7 vitamin helps in gluconeogenesis, the synthesis of glucose from amino acids. This vitamin is also involved in the synthesis of fatty acids and metabolizes amino acids. Biotin is a known beauty vitamin for great hair and skin health. Taking biotin supplements as one of the prenatal vitamins aids in healthy embryonic growth.

You may need to intake a lot of biotin-rich foods during pregnancy. Biotin deficiencies are very rare in normal human beings, but pregnant women may experience them. Hence, doctors prescribe an optimal amount of biotin supplement for a healthy pregnancy. While the deficiency can still be mild, it is important to supply enough biotin to the body during pregnancy. Biotin also helps in maintaining the glow on the skin while you carry your little bundle of joy inside.

How Much Vitamin B7 is Optimal During Pregnancy?

Optimal Vitamin B7 During Pregnancy

The need for micronutrients is always a little high during pregnancy since the body is in constant need of replenishing its cells with energy to sustain the pregnancy. Prenatal vitamins are very helpful at this stage. But certain vitamins like vitamin B7 can be obtained by eating biotin-rich foods. Study shows that biotin deficiency is very rare yet very mildly possible in 30-50% of pregnancies. Hence, it is important to understand and get the dosage from your doctor before taking a biotin supplement.

Biotin deficiency may cause hair thinning, brittle nails, and poor metabolism outcomes like fatigue, insomnia, and depression. Hence, intake of supplementary biotin is important as pregnant women tend to lose biotin faster than normal people. Excess intake of biotin may sometimes cause miscarriages and other health issues like rashes on the skin, digestion and kidney problems, and other issues like diabetes. It may also interfere with other underlying health conditions.

Excess biotin may sometimes lead to misdiagnosis of health conditions like thyroid. Hence, consulting your doctor may help you understand the amount of biotin your body needs. Study shows that the optimal amount of biotin during pregnancy is 30 micrograms, which may not lead to toxicity. Lactating mothers may require slightly more biotin than pregnant women. It is vital to understand that pregnancy can break down biotin faster than the normal rate.

What Foods Are Rich in Vitamin B7?

Foods Rich in Vitamin B7

Numerous foods can provide a sufficient amount of biotin required for the body.

  • Fruits and vegetables like avocado, banana, cauliflower, broccoli, green peas, cabbage, apple, plum, and sweet potatoes are quite rich in biotin.
  • Animal products like milk, cheese, and egg yolks are excellent sources of biotin.
  • Certain kinds of seafood like salmon fish have biotin in them
  • Nuts like peanuts and walnuts contain a good amount of biotin.

Consuming biotin-rich foods for a normal human being can fulfil the need. But pregnancy is different, and it may need a slightly increased amount in the form of supplements.

Hence, prenatal vitamins that contain optimal amounts of biotin should be enough to fulfil the needs of a pregnant woman.
