Folate 2.8 ng/mL — what does it mean?
Folate (vitamin B9)
- What most labs call normal
- 3–17 ng/mL
- Where you actually want to sit
- 10 ng/mL and above
What this test is
Your level of folate (vitamin B9), B12’s partner in building and repairing DNA.
What your number means
10 or above is the target. Under 6 is a real shortfall, and that’s where DNA copying starts letting errors through. Folate and B12 are a pair — if one is low it’s worth checking the other, because a dip in either pushes your homocysteine up.
Why it matters
Folate and B12 work as a pair to keep your cells’ DNA intact each time they divide.
If B12 helps run the DNA copier, folate supplies the fresh paper and ink. Run short and the copies come out with gaps and breaks, so new cells get built from a damaged blueprint.
What to do about it
Leafy greens, beans, lentils and citrus are the everyday fix, and a B-complex supplement covers the gap. Retest it alongside B12 and homocysteine.
Where it sits in your Body Age
Folate is one of the tests behind Metabolic Fuel — Whether you have the vitamins and minerals your body needs on hand to repair itself. It is one of four areas that together give a single number: the age your body reads, next to the age on your birth certificate.
