5. Chromium for boosting mood
Chromium is a dietary trace mineral that has an important role in the synthesis of neurotransmitters, chemicals that send messages between nerve cells. Chromium increases serotonin levels as well as norepinephrine, a naturally occurring chemical in the body that acts as both a stress hormone and neurotransmitter. Some studies have shown chromium supplementation to be useful in treating depression.
The RDA for chromium is 120 micrograms, but the average daily dietary intake is only 25 to 50 micrograms per day.
