Vitamin B12 plays an important role in many metabolic and hormonal functions in the body. Foods such as grass-fed beef, dairy products and fish all contain a hefty dose of the vitamin, but it’s one of the most common nutrition deficiencies in the world. A Vitamin B12 deficiency can cause problems such as fatigue, weakness, constipation, depression and poor concentration. Low dietary intake and poor lifestyle habits can lead to a deficiency, which can cause risks during pregnancy and negatively impact neurological health and cardiovascular health. B12 injections can help quickly elevate levels of the vitamin in someone who is deficient. The injections come with many benefits, as well as some risks. (1)
