At the beginning of pregnancy and even before conception we have lots of questions regarding our diet and what is best for baby. As we all know a healthy balanced diet is the best way to get the vitamins and minerals you need. Supplements can also help support the bodies increasing nutritional needs during pregnancy. For anyone considering a taking a supplement during pregnancy they should speak to their healthcare professional about how best to manage.
The importance of prenatal vitamins
During pregnancy, our bodies experience increased physiological changes to support metabolism in the mother and growing foetus and this leads to an increased need for micronutrients .
It is recommended that all pregnant women and those planning to conceive should take a supplement containing 400mcg of folic acid. This is to reduce the risk of problems in the baby’s development in the early weeks of pregnancy. 
A healthy balanced diet is important and those that need a further support to cover any nutritional gaps in your diet a prenatal supplement can help support you in managing an increased demand. For example, the demand for iron increases threefold during pregnancy  which may make it difficult to get enough iron from diet alone.
When you should start taking prenatal vitamins
When is the right time to start a prenatal vitamin? well for those who are planning to conceive there is an opportunity to prepare your body and ensure you have a healthy balanced diet. It is recommended that you take folic acid for at least 1 month in advance of conception.
For those who did not have the opportunity to plan their pregnancy it is important to start taking folic acid as soon as possible and for a minimum of 12 weeks. Prenatal vitamins are suitable to take in early pregnancy and are designed to complement a healthy balanced diet. Iron is one of the key nutrients monitored by your healthcare professional during pregnancy.
Your healthcare professional will advise you on your iron levels and may recommend that you take an iron supplement from early in your pregnancy.
The best prenatal vitamins to take to take before you get pregnant
With such a wide selection of products on offer choosing the right prenatal vitamin can be a challenge. For those who may have pregnancy complications or any other health concerns its best to consult your healthcare professional before taking a prenatal supplement.
Rather than taking individual supplements it may be easier to take a product that combines a number of the essential nutrients for pregnancy. If looking at combination products it is important to ensure they contain sufficient amounts of each nutrient.
Whatever your choice it is important to ensure your prenatal vitamin contains folic acid. It is recommend that you begin taking folic acid supplements before you conceive. This is because folic acid helps reduce the risk of neural tube defects (NTD). A baby’s neural tube will develop into both the brain and the spinal cord and it develops during the first month of pregnancy. The beneficial effect is obtained with a supplemental intake of 400ug of folic acid daily for at least one month before and up to three months after conception.
If you are following a restricted diet a prenatal vitamin that contains iron would be a good choice. Iron is well known to cause side effects so when choosing your supplement ensure to choose one that is gentle on the stomach.
The best vitamins to take while you are pregnant
We all know the importance of maintaining a healthy balanced diet during pregnancy, but this may not always be possible. Particularly for those who suffer with morning sickness. Nutritional supplements can be of benefit during pregnancy to help support any potential nutritional gaps.
It is recommended that all pregnant women take Folic acid for a minimum of 3 months after they conceive. When choosing a folic acid supplement ensure it is one that is suitable for you. Folic acid comes in different forms; L-Methyl folate is an active naturally occurring form of folate. A genetic predisposition occurs in up to 67% of the world’s population limiting their ability to absorb folic acid in its synthesised form , an active form such as L-methly folate could help significantly improve absorption. Supplemental folic acid helps to reduce the risk of neural tube defects (NTD).
A nutrient that is monitored closely during pregnancy is iron. With a blood volume increase of between 40% – 50%  your body’s demand for iron increases significantly as your pregnancy progresses. Iron supplements are recommended for women who are unable to meet their iron requirement through diet alone.
Another nutrient that has an important role to play during pregnancy is Omega 3 DHA. Omega-3s are a family of long-chain polyunsaturated fatty acids and are essential nutrients for health and development. They are not synthesized by the human body and therefore must be obtained from diet or supplementation. DHA is important during pregnancy as it helps support foetal eye and brain development. The beneficial effect is obtained with a daily intake of 200mg of DHA in addition to the RDA for omega-3 fatty acids.
The Best Vitamins To Take Post Pregnancy
After giving birth you need good nutrition to support healing and recovery. And for mothers who are breast-feeding there is an increased demand on your nutritional intake. A healthy balanced diet is essential, and you should ensure you have sufficient intake of the following nutrients:
- Iron which is important to replenish the iron you lose during childbirth.
- Vitamin B12 is helps red blood cell development and energy production.
- DHA, an omega-3 fatty acid for breast feeding to support babies’ eye and brain development.
- Vitamin D. to supports the immune system, brain, and nervous system.
If you are unable to get sufficient intake from diet alone supplements can help support any nutritional gaps particularly for those on restricted diets such as vegetarians.
Prenatal vitamins: Conclusion
In combination with a healthy balanced diet, prenatal vitamins can help to support nutritional gaps at all stages of pregnancy. They come in many forms, tablets, liquid, capsule and gummies so you should be able to find one that suits you. When making your choice remember that Folic acid is recommended for at least 1 month and 3 months post conception. It can be taken alone or as part of a multivitamin.
