Thank you for taking the Metabolic Type Quiz
Serotonin is one of the body’s key neurotransmitters. It plays an important role in regulating mood, appetite, sleep and energy levels.
When serotonin production is lower than it should be, these systems can begin to feel out of balance. Many women notice a persistent low mood, reduced motivation or a sense that everyday tasks require more effort than they once did.
Cravings for carbohydrates, particularly later in the day, are also common. This happens because the body uses carbohydrates to help transport tryptophan, the amino acid used to produce serotonin, into the brain.

Sleep can also be affected. Serotonin is the precursor to melatonin, the hormone that regulates sleep. When serotonin levels are lower, melatonin production may also be reduced, which can make sleep feel lighter or less restorative.
This is why the Serotonin Type often involves both mood and sleep symptoms at the same time.
The encouraging thing about this pattern is that the brain’s serotonin pathways usually respond well when they are supported properly.
This is where to start.
Keep consistent sleep and wake times
Serotonin and melatonin production follow a circadian rhythm. Going to bed and waking at the same time each day helps stabilise this rhythm and supports the brain’s natural sleep-wake cycle.
Get natural light early in the day
Exposure to daylight helps stimulate serotonin production. Spending time outside in the morning, even for a short walk, can help support both daytime mood and nighttime sleep.
Reduce bright light in the evening
Artificial light, particularly from screens, can suppress melatonin production. Dimming lights and limiting screen use in the hour before bed helps the brain prepare for sleep.
Include some carbohydrates with your evening meal
Tryptophan requires a small amount of carbohydrate to reach the brain effectively. Including foods such as sweet potato, squash, new potatoes or parsnips with dinner can help support the pathway that produces serotonin and melatonin.
