Serotonin Supplement Market Size, Share & Forecast Report - 2026 to 2030

The global serotonin supplement market size was valued at around USD 1 billion in 2024 and estimated to register a sustainable CAGR of ~ 5% during the forecast period from 2025 to 2030. The rising prevalence of anxiety and mood disorders worldwide primarily drives the market growth. Additionally, the constant rise in insomnia and altered sleep pattern across all age groups throughout the globe further accentuates the serotonin supplements market growth.

Serotonin supplements are a very safe and non-drug option for elevating the levels of neural serotonin which is a major neurotransmitter. The majority of prescription drugs used for treating mental disorders are exerting their pharmacological effect by increasing the serotonin levels, but the severe side effects associated with them render them ineffective in the long-term management of mental disorders. Serotonin supplements that boost the natural production of serotonin in the human body are 5-hydroxytryptophan, tryptophan, s-adenosyl methionine, pyridoxine, folic acid, L-theanine, Rhodiola Rosea, Garcinia cambogia, etc.

Industry Trends Shaping the Serotonin Supplement Market:

The serotonin supplement market is gaining momentum as consumers increasingly seek natural solutions for managing stress, anxiety, depression, and sleep-related disorders.
