In a Nutshell
  • Nearly half of patients with hypothyroidism and Hashimoto’s have a vitamin B12 deficiency.
  • Vitamin B12 is required for proper red blood cell formation, cognitive function, and DNA synthesis.
The Research

Alleviates thyroid symptoms

Research shows that there is a high prevalence -- approximately 40% -- of B12 deficiency in hypothyroid and Hashimoto’s patients. This prevalence may be due to the high association between anemia and hypothyroidism. Anemia is when your body lack’s enough healthy red blood cells to carry oxygen to your body’s tissue, causing tiredness and weakness. Pernicious anemia can impact the absorption (or lack thereof) of vitamin B12. Supplementing with B12 may lead to an improvement in hypothyroid symptoms.

Improves cognitive function

A B12 deficiency may cause a buildup of homocysteine (an amino acid) in the blood and might decrease levels of substances need to metabolize neurotransmitters. Elevated homocysteine levels are associated with cognitive impairment, and studies show that low vitamin B12 status is associated with more rapid cognitive decline.  However, supplementing with B12 may only useful for cognition if there is a nutritional deficiency of B vitamins. A study in the American Journal of Clinical Nutrition evaluated the effect of supplementing with folic acid, vitamin B12, and vitamin B6 on cognitive function in women at high risk of cardiovascular disease. Compared to the placebo group, supplementation did not affect the average cognitive change from the baseline. However, in a small group of women with low baseline dietary intake of B vitamins, supplementation significantly slowed the rate of cognitive decline.

Enhances energy and endurance

Due to its role in energy metabolism, B12 is sometimes considered to enhance energy, athletic performance, or endurance. This is partially true, considering that correcting anemia caused by vitamin B12 deficiency may improve the associated symptoms of weakness and fatigue. B12 will likely not improve symptoms in those with already sufficient levels of this vitamin. Since vitamin B12 is a water-soluble vitamin, your body cannot store extra amounts. Instead, any excess passes through your body. So, if you are deficient in vitamin B12, you may see an improvement in your energy levels.
