9 Science-Based Benefits of Vitamin B12

Improve Heart Health by Decreasing Homocysteine

Increased blood levels of amino acid homocysteine are connected to a high risk of heart disease. Another name for a high homocysteine level is called hyperhomocysteinemia, which can cause blood clots in the blood vessels. So, individuals that are deficient in vitamin B13 have elevated homocysteine levels.

Common symptoms of vitamin B-12 deficiency linked to elevated homocysteine include fatigue, dizziness, mood changes, weakness, pale skin, tingling sensations, and mouth sores.

According to research [10], it has been proven this vitamin helps in decreasing homocysteine levels, which could lessen the risk of heart disease. Currently, there is no scientific evidence that confirms that vitamin B12 supplements are effective in this scenario.
