                                According to Harvard Medical School, a severe vitamin B12 deficiency can lead to a host of neurological issues, including loss of taste. This confirms that a direct link exists between a deficiency in this essential vitamin and a compromised sense of taste. This condition, medically known as dysgeusia or atrophic glossitis, can significantly impact a person's quality of life.
