Most of the time, it’s hard to see just how important a certain vitamin is to our bodies until we get deficient in it and start suffering the consequences. This is definitely the case with vitamin B12. Although scientists do know that B12 is important for the brain and the red blood cells, most of us take the vitamin for granted until we start experiencing problems like low energy, depression, insomnia, poor memory, and anemia, all of which can be caused by too little B12 in the body. A blood check up can determine if your blood contains too little vitamin B12, and your doctor can prescribe a B12 supplement to help you regain your health through regular doses of the vitamin.
Vitamin B12 supplements are best taken in a capsule or pill form, although there is also the other method where a gel containing B12 is placed inside the nose. For extreme vitamin B12 deficiency, the doctor can decide to give a vitamin B12 injection right away, and these injections can be given once a month or less frequently, depending on how the person reacts to the vitamin and how much he or she needs the vitamin. For oral form, vitamin B12 can also come in a combination with the other B vitamins for a vitamin B complex pill.
Taking regular B12 supplements can ensure good energy, less risk of developing insomnia, a healthier immune system, a sharper memory, good blood circulation, and a properly working nervous system. However, vitamin B12 should not be seen as a medicine, for it is only a vitamin that can keep people healthy and lack of which can definitely make us ill, but it cannot cure health problems and diseases not associated with deficiency of the vitamin. For example, a person with an autoimmune disease like rheumatoid arthritis, cancer or AIDS can keep their strength up and health better with B12 supplements, but they pills or injections won’t get rid of the disease.
More and more people are becoming aware of the importance of having enough B12 in their bodies, and this has led to B12 supplements being taken for depression, fatigue, weight loss, and insomnia remedies. To make sure you are not deficient in the vitamin, visit your doctor first, who can verify whether you need to take B12 supplements or not. A diet rich in lean meat and dairy products is usually more than enough to ensure you get all the vitamin B12 you need, so consult your doctor first before deciding to take B12 supplements right away.
