Ginger and Depression: Impact on Serotonin and the Brain

Depression is a neurobiological illness involving deficiencies in serotonin, dopamine ginger and norepinephrine, but also increasing neuroinflammation. The ginger acts on both axes — with a safety profile far superior to chemical antidepressants.

Ginger and the serotonin-dopamine axis

Preclinical (animal) studies show that ginger extract increases serotonin and dopamine levels in the prefrontal cortex and hippocampus. The likely mechanism: inhibition of MAO-A (monoamine oxidase A), the enzyme that breaks down serotonin — a mechanism similar to MAOI antidepressants.

Neuroinflammation and depression

The inflammatory theory of depression is gaining ground: high levels of CRP, IL-6 and TNF-α are correlated with depressive severity. Classic antidepressants paradoxically show anti-inflammatory effects. Ginger, by reducing these markers, could help improve mood via this mechanism.

Ginger and intestinal axis-brain

90% of the body's serotonin is produced in the gut. Ginger improves intestinal motility and reducesanti-inflammatory-inflammation-natural-remedy">inflammation of the mucosa — which optimizes intestinal production of serotonin and improves communication on the gut-brain axis (via the vagus nerve).

Clinical study on mood

A pilot study (Phytomedicine, 2017) on postmenopausal women shows that ginger extract supplementation significantly improved mood scores and reduced anxiety symptoms after 8 weeks. Data on major depression are still insufficient — ginger is a complement, not a replacement for psychiatric treatments.

INTI Drink and mental health

The ginger + combination turmeric-black-pepper-synergy-benefits">turmeric from INTI targets the two axes of neuroinflammation. Sugar free — important because diets high in sugar are associated with an increased risk of depression (meta-analysis, British Journal of Psychiatry, 2017). comparison INTI vs GIMBER (~34g/100ml) fits into this pro-inflammatory profile.
