Do you want to be healthy?
Well, that was a rhetorical question, wasn’t it? Of course, we all want to be healthy. So, the question is not if we want to, but if we know what the requirements are.
Exercise, sleep, nutrition and all are fine – but there is one nutrient that is very important (and which doesn’t get much attention) that I am here to talk about – folic acid.
One question – why is it important? Keep reading to find the answers. Here you will learn about top foods high in folic acid and much more.

Folate – A Brief
Most of us would have probably heard of folate a number of times. But what is it? What has it got to do with our being healthy?
Folate is a water-soluble B vitamin. It is naturally present in some foods, added to certain others, and also available in the form of supplements. This vitamin is vital for cell growth and metabolism (1).
Now, the vital question – we can consume folic acid through supplements, right? Why rely on natural foods? Both are same anyway, aren’t they? Before I answer this question, there is something else you must know.
Folate Vs Folic Acid
We have seen what folate is. But what about folic acid? Well, both are one and the same – except for a distinct difference.
Folate and folic acid are the different forms of vitamin B9. Only that folate is the natural form of vitamin B9. Folic acid, on the other hand, is the synthetic form of vitamin B9. It is used in supplements and added to certain food products like breakfast cereals or flour.
The digestive system converts folate into the biologically active form of vitamin B9, called 5-MTHF. But this is not the case with folic acid. Folic acid is converted into 5-MTHF in the liver or other tissues, and not in the digestive system (2). Which is partially why the process is not as efficient. Other factors include those who have genetic mutations in the enzyme that converts folic acid to 5-MTHF, which results in reduced activity of this enzyme and conversion process. Hence, when you take a folic acid supplement, the body may take more time to convert it into 5-MTHF, allowing the unmetabolized, folic acid to accumulate (3).
This is where the actual problem arises. Even a small dose of 200 mcg of folic acid a day may not get completely metabolized until the next dose. This can result in higher levels of unmetabolized folic acid in the bloodstream, which can cause a variety of symptoms and side-effects in some individuals such as depression, anxiety, irritability, insomnia, and sleep disturbances.
This is where we answer the question we asked before. When it is folate (naturally occurring), there is no question of it going unmetabolized. Of course, it’s natural. It is metabolized in the digestive system. Hence, no complications.
Now that we have seen which form of folate is better, let’s take a look at the best folic acid rich foods. It’s important to note that when we discuss “folic acid” from natural food sources, the form of vitamin B9 is typically methyl-folate or folinic acid (calcium folinate), another natural form of folate.

Now comes another important question. Are you getting enough of folate? Because there is a difference between just knowing about folate foods and actually enjoying its benefits, right?
Are You Getting Enough Of Folate?
Getting the optimum amount of folate on a regular basis is not rocket science. A balanced diet would help you do so. Simple.
Following is the table that talks about the recommended daily amount of folate as per the age.
In general, one must know the amount of folic acid (s)he must consume. Which we have already seen. But how about the dosage when someone is suffering from a specific health condition?
Which is what we are now going to look at.
Folic Acid Dosage For Specific Health Conditions
The dosages mentioned below are based on expert opinions, scientific research and studies, and publications. We have mentioned the health condition, the stipulated dosage, and the results the vitamin has produced.
|Anemia, caused by folate deficiency||1-5 milligrams taken orally||Positive|

Folic acid has also been used for general health maintenance in children. The dosage was 0.005-15 milligrams, taken orally daily for 2 weeks to 18 months. The results were mixed.
The results and values seen above, as already discussed, are based on expert opinions, research, and other publications. However, we strongly recommend you to not simply go by what they say. Consult with your doctor regarding the usage or dosage of folic acid for any specific health condition you might be suffering from. The same condition might be different for different individuals, and a doctor’s advice is indispensable.
Natural Folate Supplements
Touching the point we discussed in the very beginning (if you can remember), yes, folate in its natural form is always the best. But when there is a deficiency, supplements have their own role to play. They cater to the emergency.
A few important pointers to keep in mind if you are using folic acid supplements:
- If you had ever had an allergic reaction to folic acid, you should not use the supplements.
- Before taking the supplement, let your doctor know if you have kidney disease, an infection, a type of anemia not diagnosed by a doctor (but confirmed by lab tests), or if you are an alcoholic.
Folic acid supplementation has its own benefits and risks. The benefits it has for pregnancy are enormous. But beyond pregnancy is where the speculation arises (36).
Folic acid is an essential vitamin that is responsible for metabolism and optimal functioning of the human body. The foods that you eat every day are rich in this vitamin – you only have to eat them in adequate quantities.
Let us now look a few frequently asked questions.
Expert’s Answers For Readers’ Questions
