Ingredient information: Vitamin B9
What is vitamin B9?
Vitamin B9, or folic acid, is a water-soluble vitamin. It is present in animals in the form of folates (polyglutamates).
What are its properties?
Vitamin B9 is fairly heat resistant but is sensitive to light, ultraviolet rays and oxidation.
Vitamin B9 plays a role in many bodily functions. It is involved in, among other things:
- cell renewal and multiplication
- the regulation of gene expression
- to the production of red blood cells and white blood cells
- to the renewal of the intestinal wall
- to skin renewal
It is found in food primarily in:
- dry yeast
- the liver
- spinach, watercress, or lamb's lettuce
- green vegetables
- beans, lentils
- wholemeal bread
- kidneys
- cheese
- eggs
- and to a lesser extent in fruits and animal products
Vitamin B9 deficiency is rather rare and is observed in cases of intestinal malabsorption (pathological cases) or alcoholism and causes, in particular, muscle cramps and anemia.
The need for vitamin B9 is critical in pregnant women, particularly during the closure of the neural tube. A deficiency can lead to birth defects, including the infamous spina bifida . Currently, the recommendation is for all women planning a pregnancy to take vitamin B9 supplements.
The recommended intake is 330µg/day for men, 300µg/day for women.
For pregnant women, the recommended intake is increased to 400µg/day.
