Mood supplements are designed to support emotional well-being, reduce stress, and help balance mood by using natural ingredients that influence brain chemistry and stress responses. Common ingredients include omega-3 fatty acids, which support brain health and may alleviate mood swings and depression, and B vitamins, particularly B6, B12, and folate, which are vital for neurotransmitter production. Adaptogens like ashwagandha and rhodiola rosea help the body adapt to stress and improve resilience, while 5-HTP and L-tryptophan are precursors to serotonin, the “feel-good” neurotransmitter. St. John’s Wort is often used for mild depression, while magnesium helps relax the nervous system.
