10. Vitamin B6
Vitamin B6 helps with neurotransmitter production, and is essential for the transformation of tryptophan into serotonin, which helps to regulate mood. Vitamin B deficiency can increase the risk of depression, and studies have suggested that vitamin B6 can help reduce depression symptoms.
Although it’s rare to be a B6 deficient, research shows that many people could have a mild deficiency.
The RDA for vitamin B6 is 1.3 mg/day for adults
