Folic acid, a synthetic vitamin folate version (also known as vitamin B9), plays a vital role in the body’s production of healthy red blood cells and is found in certain foods. This article aims to provide essential information about this, its benefits, and the appropriate dosages for various conditions.
Folate is a natural vitamin found in certain foods, while folic acid is its synthetic counterpart. Both forms are essential for proper cell division and DNA synthesis in the body. It can treat folate deficiency anaemia and supports healthy development during pregnancy. It can also reduce side effects from specific medicines.
Folic acid supplements effectively address folate deficiency anaemia, a condition where the body lacks sufficient folate, leading to a decreased number of healthy red blood cells (RBCs).
During early pregnancy, folic acid plays a role in preventing neural tube defects in the developing baby, such as spina bifida. Medical experts advise expectant mothers to take these supplements before conception and continue throughout the first 12 weeks of pregnancy.
Individuals undergoing treatment with methotrexate, a medication used for severe arthritis, Crohn’s disease, or psoriasis, may experience fewer side effects when taking folic acid alongside it.
Folic acid can combine with ferrous fumarate (also known as Iron(II) fumarate) and ferrous sulphate (also known as Iron(II) sulfate) to treat iron deficiency anaemia.
It is also commonly included in multivitamins and mineral supplements to support overall health.
The appropriate folic acid dosage varies depending on the purpose of its use:
For women planning to conceive and during the first 12 weeks of pregnancy, the recommended daily dose is 400 micrograms.
Doctors may advise pregnant women at a higher risk of neural tube defects to take an increased daily dose of 5mg.
Adults and children over one year old should take 5mg of folic acid once a day. But doctors may increase the dose to 15mg daily in some cases.
Adults and children aged 12 years and over should take 5mg of folic acid once every 1 to 7 days for prevention.
For individuals taking methotrexate, the usual dose is 5mg once a week, on a different day than the day they take methotrexate. Some people may take 1mg to 5mg daily, apart from the day they take methotrexate.
It is generally safe for most adults and children. However, some individuals should exercise caution and consult their doctors before starting folic acid supplementation, including those who:
#1 Dosage Adjustments
Healthcare providers may adjust the prescribed dose of folic acid based on individual health conditions, age, and diet. They may also conduct blood tests to determine the appropriate dose.
You can consume it either with or without food. If the folic acid is in liquid form, ensure measuring it using the provided syringe or spoon.
#3 Missed Doses
If you forget to take a dose, consume it when you remember. However, do not double the dose to compensate for a missed one.
#4 Interactions with Other Medications
Folic acid may interact with certain medications, such as methotrexate and some cancer treatments. Inform your doctor of all medications and supplements you are taking before starting this acid.
#5 Herbal Remedies and Supplements
Consult your pharmacist or doctor before combining folic acid with herbal remedies or supplements, especially those containing zinc, to avoid exceeding the recommended daily amount.
Folic acid, a synthetic version of the natural vitamin folate, is essential for various bodily functions. It treats folate deficiency anaemia, promotes a healthy pregnancy, and minimises side effects from specific medications.
