How the Digestive System Works 1 There are two basic types of vitamins in the food we eat: water-soluble and fat-soluble. 2  The water-soluble vitamins (B vitamins and vitamin C) are absorbed easily along with the water in the small intestine, where they then travel through the body via the blood vessels. Then the smaller protein molecules become known as amino acids. 2  They're now small enough to be absorbed through the small intestine and right into the blood. 3  Vitamins: While our food is digested, vitamins are absorbed in the small intestine.

Vitamin B 12 Vitamin B12, vitamin B12 or vitamin B-12, also called cobalamin, is a water-soluble vitamin with a key role in the normal functioning of the brain and nervous system, and for the formation of blood.It is one of the eight B vitamins.ethyl-B 12 is absorbed by an intestinal mechanism using intrinsic factor and by a diffusion process in which approximately 1% of the oral dose is absorbed. The human physiology of vitamin B 12 is complex, and therefore is prone to mishaps leading to vitamin B12 deficiency.

What Are the Health Benefits of Vitamin B12 Drops? The benefits of supplementing with B-12 drops include better absorption and convenience. Vitamin B-12 is an essential, water-soluble vitamin found naturally in animal meats such as beef, poultry and fish. It is critical to the formation of red blood cells, proper nervous system function, and the production of DNA.itamin B-12 drops are taken sublingually, or placed under the tongue. The vitamin is absorbed by the membranes under the tongue and gets into the bloodstream quickly, resulting in up to a 100-percent absorption rate.

How are fat-soluble vitamins absorbed by the body? Absorption of fat-soluble vitamins. 1  Food containing fat-soluble vitamins is ingested. 2  The food is digested by stomach acid and then travels to the small intestine, where it is digested further. 3  Upon absorption, the fat-soluble vitamins enter the lymph vessels before making their way into the bloodstream.

Jigsaw Activated B w/SRTÂ® Activated simply means that the B vitamins are in their active form. Most vitamin B supplement products contain only the inactive forms. Inactive B vitamins require conversion by the liver so they can be absorbed and utilized. But because your liver can only convert them so fast, they are often quickly eliminated from your body before offering much benefit. With Activated B w/SRT®, the work of conversion is already done for you.

What Does Your Body Do to Excess Vitamin B or C That You Might Consume? The body has an efficient system to absorb, metabolize, store and excrete vitamins so that it gets what it needs to function and it eliminates the excess. Vitamins B and C are water soluble and any surplus of these vitamins is excreted in the urine.

How Does the Body Absorb Carbohydrates, Lipids, Fats and Proteins? Fat-soluble vitamins -- A, D, E and K -- dissolve in fat to be absorbed and stored for later use. Water-soluble vitamins are not easily stored and surplus amounts are excreted in your urine. Fat-soluble vitamins require bile acids for absorption and are stored in the liver and fatty tissue of the body.

How does the body absorb vitamins? The small intestine is where vitamin absorption happens (along with most other types of absorption). Water-soluble vitamins, such as vitamin C, have active transports for absorption -- molecules that pick them up in the small intestine, in a section called the jejunum, which is located about midway through.

Vitamins, Minerals, and Trace Elements The Schilling test is performed to evaluate vitamin B12 absorption. B12 helps in the formation of red blood cells, the maintenance of the central nervous system, and is important for metabolism. Normally, ingested vitamin B12 combines with intrinsic factor, which is produced by cells in the stomach. Intrinsic factor is necessary for vitamin B12 to be absorbed in the small intestine. Certain diseases, such as pernicious anemia, can result when absorption of vitamin B12 is inadequate.

How Is Vitamin B12 Absorbed by the Body? Factors that Affect Absorption. In order for B12 to be adequately absorbed, you must have a healthy stomach, small intestine and exocrine pancreas that creates the digestive enzymes. Also, you must produce sufficient amounts of intrinsic factor. Other factors include inadequate consumption of B12-rich foods and over-consumption of alcohol.
