Standard B12 Single
B12 is an essential water-soluble B Vitamin. It is crucial to the nervous system and to build red blood cells. It is not found in plant-based foods, so it might be important to those on strict vegan or vegetarian diets to supplement. Memory loss, fatigue and weakness are earlier signs of deficiency. More serious health conditions might develop without proper levels of vitamin B12.
Vitamin B12 is part of the vitamin B complex and can be found naturally in foods such as meat, milk, cheese, fish, lobster, crab and oysters. Vitamin B12 creates stores of energy in the body that can be used for several years. However, deficiencies can cause a person to require vitamin B12 shots.
SYMPTOMS OF VITAMIN B12 DEFICIENCY
If a person is deficient in vitamin B12, she may suffer a range of symptoms. A patient may feel shaky at times and find it hard to walk steadily due to muscle weakness. Mood disturbances are also common for individuals who do not get enough vitamin B12. Additional reported symptoms include altered vision, low blood pressure and bladder problems. Supplementation through vitamin B12 injections may be recommended to alleviate these symptoms.
