The Best Folic Acid Supplements UK

Folic acid is the synthetic form of a natural substance called folate. It is not made in the body or found in nature, but your body can convert it into active folate. Folate provides essential functions throughout your body and helps you to stay healthy and active. 

In the UK, many people don’t get enough folate through their diet, so it is necessary to take folic acid to boost your folate levels. Some governments across the world, including in the UK, routinely fortify staple food items like bread with folic acid.

As well as any folic acid or folate received through your diet, there are several situations in which you must consider taking an extra daily amount. To help you decide if, when and how to take folic acid, let’s go through the details and then introduce you to the best supplements available in the UK.

What is Folic Acid? 

Folic acid is a synthetic substance that is used to boost folate levels in your body. It is used instead of folate because it is easier to produce, and remains stable during storage. When you take folic acid, a series of enzyme driven processes convert it into folate.

Folate, also known as vitamin B9, is one of the B vitamins. It is needed for vital biochemical processes such as making red blood cells and cell division. It can be found in many foods including legumes, eggs and leafy greens.

Reasons to Take Folic Acid 

Folate is an essential part of our daily diet. However, there are several reasons why you might need to top it up with a daily folic acid supplement.

-To reduce the risk of problems in early pregnancy

The NHS recommends that pregnant women should take between 400 and 600µg during the first 12 weeks of pregnancy. Folate rich foods should also be eaten during this time as well as daily supplementation. This is to prevent congenital disabilities like spina bifida. Higher levels of folate in a mother can significantly reduce the chances of the baby suffering from a group of conditions known as neural tube defects.

In cases where doctors believe that there is a higher chance of a neural tube condition, they advise a high daily dose of 5mg of folic acid. Higher doses like this should only be taken on the advice of your doctor.

-To treat or prevent folate deficiency

Low levels of folate in your body can cause a range of symptoms including tiredness, muscle weakness, headaches, dizziness and shortness of breath. When it occurs over a longer time, more severe conditions like folate deficiency anaemia can develop. This is when the long term lack of folate results in your body being unable to make fully functioning red blood cells.

-To reduce the side effects of methotrexate

This is a medicine used to treat arthritis, Crohn’s disease and psoriasis. It is known to cause unpleasant side effects such as nausea, diarrhoea and dizziness. In the UK, when a doctor prescribes it, Folic Acid is often given as well to reduce their severity.

-To boost fertility

Folate is involved in the division of cells and the production of new genetic material. This means that it is crucial to the creation and growth of healthy sperm and also provides a significant role in supporting female fertility and preparing you to become pregnant.

There is still much to be understood about the specific ways in which folate increases male and female fertility. Still, studies are increasingly highlighting the link between better pregnancy outcomes and folic acid supplementation.

How Much Should I Take?

The average adult requires a daily amount of 400µg of folate, which is increased to 600mcg if you are pregnant. For some conditions, you may need a more significant amount, but in this instance, you should take to your doctor about your symptoms first.

Are There Any Side Effects? 

Side effects from taking the daily recommended amount of 400µg of Folic acid are unlikely, but some people may experience nausea, loss of appetite, or bloating. There are also some related conditions and complications that should be looked out for. Some people are allergic to Folic acid, and others have a genetic condition that prevents their body from successfully converting it into folate. This can result in a build-up of folic acid and cause your folate deficiency to remain untreated. If you are taking folic acid and your symptoms continue, visit your doctor and explain your concerns.
