QUESTION: Which vitamin deficiency causes depression?
- ANS: Vitamin D deficiency has been linked to an increased risk of depression.
- Vitamin D is unique because it functions as both a vitamin and a hormone in the body, and it is involved in several processes that influence brain health.
- It plays a role in regulating neurotransmitters such as serotonin, which is known to be involved in mood regulation.
- Vitamin D receptors are found in areas of the brain related to depression, and studies have shown that vitamin D can influence the synthesis and metabolism of serotonin.
- Vitamin D is also involved in regulating the immune system and reducing inflammation.
- Low levels of vitamin D may contribute to increased inflammation in the body, which in turn could impact mood and mental health.
- Inadequate sunlight exposure and certain factors can lead to vitamin D deficiency.
