Does vitamin B accumulate in the body?

The B-group vitamins are a collection of eight water-soluble vitamins essential for various metabolic processes. Most of these vitamins can’t be stored by the body and must be consumed regularly in the diet.

How are most excess B vitamins excreted from the body?

As the B vitamins are water-soluble, any excess is generally excreted in urine. On the one hand, this means they are typically safe at doses much higher than the RDA, but on the other hand, they require a more consistent consumption than the fat soluble vitamins.

How is vitamin B excreted?

Without intrinsic factor, vitamin B12 moves through the intestine and is excreted in stool. Because vitamin B12 is necessary for the formation of mature blood cells, deficiency of this vitamin can result in anemia.

Can B vitamins be lost during food processing?

B-complex vitamins and vitamin C are water-soluble vitamins that are not stored in the body and must be consumed each day. These vitamins can be easily destroyed or washed out during food storage and preparation.

How are B vitamins metabolized?

Dietary vitamin B12 exists in complex with dietary protein and is decomposed to free vitamin B12 by pepsin in the stomach. Free vitamin B12 is absorbed by the epithelial cells of the small intestine via intrinsic factor (IF), a gastric glycoprotein.

How are vitamins excreted from the body?

Water-soluble vitamins travel freely through the body, and excess amounts usually are excreted by the kidneys. The body needs water-soluble vitamins in frequent, small doses.

Is vitamin B excreted in urine?

We conclude that urinary excretion of vitamin B(12) is dependent upon urine volume, but not on intake of vitamin B(12). Physical characteristics and urine volume are less important for B-group vitamins except for vitamin B(12) as biomarker.

Where are B vitamins digested?

How is vitamin B-12 excreted from the body?

Vitamin B12 is a water-soluble vitamin. Water-soluble vitamins dissolve in water. After the body uses these vitamins, leftover amounts leave the body through the urine.

Are B vitamins stored in adipose tissue?

The four fat-soluble vitamins are vitamins A, D, E, and K. These vitamins are absorbed more easily by the body in the presence of dietary fat. Water-soluble vitamins are not stored in the body. The nine water-soluble vitamins are vitamin C and all the B vitamins.

What is the primary role of the B vitamins?

B vitamins are important for making sure the body’s cells are functioning properly. They help the body convert food into energy (metabolism), create new blood cells, and maintain healthy skin cells, brain cells, and other body tissues.
