Typically, healthy people can get adequate amounts of folate – also known as folic acid or vitamin B9 – by eating a balanced diet. However, achieving this may not always be feasible - either temporarily or permanently.  

Folates are not very stable and around 60 to 90% of the folate in food is destroyed during cooking or by exposure to light. In addition, stress and certain illnesses, for example, can result in higher folic acid requirements. Even nutrition-conscious people often find it difficult to cover their folate and folic acid requirements with food.  

Pregnant women, women looking to conceive and women who are not using contraception are expressly recommended to take folic acid supplements to ensure an adequate supply in pregnancy – be it planned or unplanned. [1] 

It can therefore be sensible to ensure optimal folate or folic acid intake by taking appropriate dietary supplements. 

The following information has been scientifically studied and confirmed by the European Food Safety Authority (EFSA). [2] 

Folate / folic acid for reproduction 

• Folate contributes to the growth of placenta during pregnancy 

Folate / folic acid for the cells

Vitality Nutritionals BioActive Folate 800 µg capsules are ideal for providing overall support for maintaining the folate balance, especially for those with an increased need for folate:  

• The German Nutrition Society (Deutsche Gesellschaft für Ernährung, DGE) advises women who are trying to or could conceive to eat a diet rich in folate. In addition, it is recommended to take 400 µg of folic acid or equivalent doses of other folates daily in the form of a supplement to prevent neural tube defects. This additional intake of a folic acid or folate supplement should begin at least 4 weeks before the start of pregnancy and be maintained during the first trimester. [4] In other countries, e.g. the USA, the recommended daily doses are 600 µg [5] or 800 m µg [6].Ask a specialist, e.g. your doctor, whether your diet is rich in folate and whether you require a folate or folic acid supplement in a higher dosage.  
• People with a permanently or temporarily restricted folate supply who do not get sufficient quantities of folate from their diet, e.g. due to their diet or while trying to lose weight. 
• People with an increased need for folate, e.g. due to illness, medication, stress, psychological strain or high alcohol consumption.  
• Elderly people with limited folate absorption due to age-related changes in digestive function. 
• etc. 

Folic acid supplements in high doses are not suitable for 

• those with folic acid hypersensitivity 
• those taking certain medications, e.g. certain anti-infectives, antibiotics such as chloramphenicol, contraceptives, some cancer drugs; if in doubt, seek medical advice 
• children, adolescents and adults who would exceed the respective tolerable total intakes with the supplement, see also the section "Do folate or folic acid in high doses have side effects?" 

According to the latest findings, a high intake of folates, which naturally occur in food, is not harmful. In contrast, a high intake of folic acid, e.g. via food supplements or fortified foods, can be harmful if the recommended intake is exceeded.  

According to the European Food Safety Authority (EFSA), the tolerable upper intake level for adults is 1000 µg of folic acid per day. For children and adolescents aged 1 to 17 years, the tolerable upper intake level is 200 to 800 µg per day. If the folic acid intake is higher over a longer period of time, the risk of adverse effects is increased. [4]
