Folate is also known as:
Vitamin B9
The recommended daily intake level of folate is ___
400 micrograms from foods or dietary supplements.
Low levels of B9 in early pregnancy are believed to be the cause of ___.
More than half of babies born with neural tube defects.
Why can a folate deficiency result in low numbers of large red blood cells (a type of anemia).
B9 is essential in the production of DNA and RNA. As such the inhibited DNA synthesis results in an impaired cell cycle (the mitosis stage can’t be reached). This results in lack of red blood cells: Megaloblastic anemia.
Megaloblastic anemia:
Megaloblastic anemia is a condition in which the bone marrow produces unusually large, structurally abnormal, immature red blood cells (megaloblasts).
Where are red blood cells produced?
Red blood cells, most white blood cells, and platelets are produced in the bone marrow, the soft fatty tissue inside bone cavities.
Since red blood cells are necessary to transport oxygen, what is a side effect of low folate?
Low oxygenated blood = fatigue
What causes folate deficiency?
Not ingesting enough foods that supply B9
You have a medical condition that gives you a higher need to B9
The body doesn’t ABSORB enough. Your body doesn’t absorb enough folic acid. This might happen if you drink too much alcohol or have severe kidney problems that require dialysis.
You take certain medications with side effects.
What is anemia?
A condition in which the blood doesn’t have enough healthy red blood cells
What are the side effects of anemia?
Anemia may make you:
Feel weak and tired. Feel lightheaded. Be forgetful. Feel grouchy. Lose your appetite and lose weight. Have trouble concentrating.
Can B9 stay in the blood?
No. Its water soluble which means it dissolves in the body until it’s either absorbed or peed out. This means the body needs to continually resupplied with it.
Are folate and folic acid the same
thing?
No. Folate is the naturally occurring form, and folic acid is the synthesized version found in fortified foods.
Is Folic Acid food fortification normal?
It’s actually required legally as of 1998, after it was deemed mandatory due to overwhelming evidence of its protective effect against neural tube defects (NTD) in newborns.
What is the difference between Folate and Folic Acid?
Folate is natural, Folic acid is made artificially.
Is it normal to find Folic Acid in food?
More than normal. It’s been standardized since it was proven to help reduce the chances of babies being born with NTDs.
