B12 is essential for the healthy functioning of the nervous system and overall health.
Unfortunately, over half of the United States population is borderline to completely B12 deficient!
The lack of this vital B vitamin can cause devastating effects: one being neuropsychiatric disorders (ex: anxiety, depression, migraine headaches, etc.). Several signs of B12 deficiency include anemia, fatigue, memory loss, shortness of breath.
The recommended dosage for adults is 2.4 micrograms; however, B12 vitamins are water-soluble, meaning that the body doesn’t store the vitamin, and it is safe to take in high doses.
Vegans and vegetarians may need to use B12 supplements to receive their daily recommended amounts since B12 is only available in animal products.
Also, specific populations, those with alcoholism, the elderly, and individuals with malabsorption disorders (ex: celiac disease), can be more deficient in vitamin B12.
Along with signs and symptoms, getting bloodwork examined by a trusted health and wellness professional to check B12 levels is the only way to know if one is sufficient or deficient in vitamin B12.
