There's several great reasons to increase your vitamin B12 intake. Research from Tuft's University stated that 40% of Americans are B12 deficient with symptoms ranging from numbness in the feet to chronic joint pain.
Vitamin B12 helps to nourish the adrenal and pineal glands as well as the nervous system which help keep your mood on an even level. In fact, Finnish research suggests taking 1,000mcg daily helps steady your mood and increases the effectiveness of antidepressant medication if your on them.
Further research involving 3,000 Americans who were low on B12 demonstrated that memory loss and confusion were the first symptoms to show up. It was found that the memory loss cleared up in as little as 3 weeks when supplemented with B12( The Live Food Factor, Susan Schenck).
Nearly half of the public experiences painful canker sores throughout their lives. The good news is an Isreali study on canker sores demonstrated that a daily supplementation of B12 (1,000mcg) showed a complete reduction of the flare-ups within 5 months in nearly 75% of the test subjects.
Lastly, a study from Tuft's University found that women with the highest levels of B12 in their diets had the most fracture-resistant bones. Osteoblasts (bone building cells) are activated by vitamin B12 to build new bone tissue.
