Folic acid is normally recommended for women who are pregnant or breastfeeding. However, it’s also one of the best vitamins for those at every stage of life. While it doesn’t sound like the most exciting of vitamins, there are numerous benefits that come with topping up on enough of it.
If you always feel tired in winter then it could be that you're experiencing a nutrient deficiency in this area. We've called on the experts to break down for you exactly what folic acid is, what happens when you don't get enough of it, and while is a particularly important component of motherhood. We'll also reveal which foods you can source it from, as well as the instances when supplements may be helpful.
What is folic acid?
Folic acid is also known as folate, the organic material in vitamin B9 (it's also a good idea to know your B vitamins too). It is important to our health, and cell production in particular. Before we get into the details, why exactly do we discuss folic acid and not folate? “Folic acid is a form of folate, but our bodies are more efficient at absorbing the former rather than the latter,” says Julie Harris, registered dietitian nutritionist and recipe creator at Angry BBQ.
Folate and folic acid help your body make new red blood cells, which carry oxygen around your body. The folic acid you ingest (more on how to do that later) plays an important role in cell division, producing more red blood cells that are the right size and shape. Since your body cannot function without this circulation of oxygen in blood cells, folic acid is the vitamin that helps your body to operate effectively.
“Folic acid’s claim to fame is the crucial role it plays in early pregnancy, reducing the risks of brain and spinal birth defects," says Linda Nikolakopoulos, a dietitian at Nutritious Measures. “However, it is also very important in the non-pregnant population. It plays an important role in maintaining healthy functioning of the heart and blood vessels.”
What happens if you don't get enough folic acid?
“Falling short on adequate folic acid levels could lead to increased risk of cardiovascular disease,” explains Nikolakopoulos. “Some research even suggests that folic acid could potentially reduce cancer risk and may be helpful in treating depression."
Harris agrees that maintaining adequate levels of folic acid is critical for your long-term health. "It can play a role in preventing type two diabetes and rheumatoid arthritis," she reveals. "Plus, a deficiency may contribute to anemia, low bone density, memory loss, and poor brain function." It's worth noting that people who have digestive or malabsorption issues, such as celiac disease, could be at increased risk of developing a folic acid deficiency.
Why folic acid is important during pregnancy
While it’s beneficial at any stage of life to get enough, Harris stresses the importance of folic acid for women who are expecting. “It’s important to have adequate levels for a developing fetus,” she explains. “It helps prevent birth defects.” She adds: "It’s essential for the DNA and cell division process." It's recommended that pregnant women take a folic acid supplement daily, and also eat foods fortified with the nutrient.
How to get folic acid in your diet
“Thankfully, there are several foods that provide high amounts of folic acid, along with other vitamins and minerals,” says Nikolakopoulos. These include:
- Dark green leafy vegetables, such as spinach, asparagus, Brussels sprouts, broccoli, and romaine lettuce
- Black-eyed peas and other beans
- Beef liver
- Whole grains
- Fortified breakfast cereals
Pregnant women can usually top up on folic acid through prenatal vitamins. They’re available over the counter and in a prescription form, depending on how much of the nutrient your doctor believes you need.
If dietary restrictions are keeping you from getting your full dose of folic acid during meal times, then a supplement may well be your best, and easiest, option. “While the ideal is to get what your body needs from actual food, folic acid supplementation is sometimes needed,” points out Nikolakopoulos. While we're on the subject, magnesium is another vital nutrient that women also require plenty of in their diet.
How much folic acid do women need?
“The daily recommended intake for women over the age of 20 is 400 micrograms," says Nikolakopoulos. "Pregnant women need a bit more—600mcg—and if you're lactating you need 500mcg per day. As a point of reference, a half a cup of cooked spinach contains about 131mcg, and a half a cup of cooked black-eyed peas is about 105mcg."
You shouldn’t overdo it, however. More than 1,000mcg of folic acid a day might have some negative side effects on your digestive system. Although, as Harris points out, folic acid is water-soluble, so a slight excess will be naturally disposed of via your body’s natural processes.
People often ask if folic acid causes constipation and other gut health issues. The short answer is no, the vitamin itself doesn’t typically create these side effects in normal doses. Too much, though, and the answer becomes more complicated. Stomach issues of all sorts can come from taking in too much of the nutrient, and there is sometimes the risk of severe reactions, including seizures and strokes, if you really overdo it.
