What is a normal folate level?

The short answer

A typical US lab prints a normal folate range of 3–20 ng/mL. That range exists to catch disease, not to describe your best.

Nobody we follow has put a number on your folate level. They talk about the dose you take, not the level in your blood.

What folate measures

A B vitamin your body needs to build DNA and make new cells.

It works with B-twelve to clear homocysteine. A shortage shows first in fast-dividing tissue like blood and a developing fetus.

What does your folate number mean?

On a typical lab range, under 3 ng/mL is low, 3 to 20 is normal and over 20 is high. Your own report prints its range next to your number, and that is the one your lab uses. Nobody we follow has drawn a line inside that range.
