Vitamin B12 is found only in foods of animal origin. As a result, vegetarians and vegans run the risk of suffering a deficiency of vitamin B12. This deficiency can be prevented by consuming vitamin B12 dietary supplements in tablets, like the ones we sell at HSN.
Vitamin B12 is essential for the proper functioning of the energy of the body and the nervous system, and its deficiency can cause serious health problems.
It is involved in the formation of red blood cells and the functioning of proteins, it promotes concentration and memory, keeps the mucous membranes healthy, and protects the heart. Vegetarians need to consume more vitamin B12 because they do not eat meat. Old people also need more vitamins, since they do not often meet their requirements just through food.
Vitamin B12 is a water-soluble coenzyme which enables the functioning of several metabolic processes by interacting with other enzymes. Vitamin B12 is significantly involved in the production of red blood cells, cell division, and transmission of nerve stimuli.
Vitamin B12, when combined with folic acid and vitamin B6, helps to keep the heart and nervous system healthy. In particular, vegans are affected by the lack of vitamin B12 and normally have low levels because they do not consume any food of animal origin.
Effects of Vitamin B12
- Almost all nerve fibers are surrounded by a protective layer that allows a fast transmission of information. Vitamin B12 plays an essential role in the production of this protective sheath.
- Vitamin B12 performs the intermediate step in the transfer of genetic information to daughter cells, especially important for red blood cells, which divide quickly.
- Vitamin B12 is needed in the stages of reproduction and pregnancy.
- Vitamin B12 is involved in the regeneration of the mucous membranes.
- Vitamin B12 is naturally produced by microorganisms in the human colon, but the amount is not enough to meet the body's requirements. For this reason, the absorption of Vitamin B12 through food is essential.
- Vitamin B12 is necessary for the functioning of the immune system.
- Vitamin B12 is necessary for the functioning of the nervous system, since it is involved in the formation of the myelin sheath that protects the nerve endings and allows the communication between them.
- Vitamin B12, along with folic acid and vitamin B6, participates in the conversion of homocysteine produced by the metabolism, preventing the development of diseases in the cardiovascular system. The amino acid homocysteine is used after various changes in gene regulation and protein production. However, if the remains of homocysteine are deposited in the body, they can cause vascular calcification.
Vitamin B12 supplements are advised for:
- Vegetarians or those who follow a vegetarian diet
- People with anemia
- Diseases and surgery of the digestive tract
- Pregnancy and lactation
- Those with high levels of homocysteine
- The elderly
- When you consume a lot of alcohol
- When you use medicines that reduce vitamin B, as in the case of medicines for cholesterol, antibiotics, antihypertensives, psychotropic, or medicines to treat several diseases: Parkinson's disease, cancer, gout, etc.
What foods contain Vitamin B12?
The best sources of vitamin B12 are found in the offal and guts of animals. Milk and eggs also contain vitamin B12, but in a very small proportion. A pure vegetarian diet does not supply the body with the vitamin B12 it needs.
The absorption of vitamin B12 from food is performed in the small intestine with the help of an intrinsic factor, a specific transport protein. The production and functioning of this protein may be interrupted by several gastrointestinal diseases, as well as by the normal aging process of the intestine, whose ability to absord nutrients deteriorates.
What are the symptoms of a Vitamin B12 deficiency?
The first signs of a lack of vitamin B12 are a tingling sensation in the hands and feet, which is often combined with the sensation of being cold. It can trigger an incipient anemia with an unnatural paleness, general weakness and strong fatigue. It can even produce an unpleasant burning sensation on the tongue.
A permanent lack of vitamin B12 affects the functioning of the nervous system, causing mood swings, memory problems, dementia, and mental confusion. The production of blood and fertility in men and women can be affected by a deficiency of vitamin B12.
Who can especially benefit from Vitamin B12 supplements?
- People with gastrointestinal diseases
- People with anemia
- People who have undergone surgery to remove gastrointestinal tissue
