Serotonin, a key neurotransmitter often dubbed the 'happiness chemical', plays a crucial role in regulating mood. It also participates in sleep, digestion, bone health, and blood clotting. The gut mainly produces serotonin, impacting the brain and body by influencing various physiological processes and emotional states. An imbalance in serotonin levels can significantly affect both mental and physical health....


Who Would Benefit from Testing Their Serotonin Levels?

Testing serotonin levels can benefit individuals experiencing symptoms of depression, anxiety, or other mood disorders. It’s also useful for those with unexplained digestive issues, sleep disturbances, or chronic pain.

Symptoms of Too Low Serotonin:

  • Depression
  • Anxiety
  • Irritability or mood swings
  • Insomnia or sleep disturbances
  • Low energy or fatigue
  • Appetite changes
  • Poor memory and concentration

What is the Difference Between Measuring Serotonin in Urine vs. Blood?

Measuring serotonin in urine reflects the body’s overall serotonin production, including what’s filtered and excreted by the kidneys. Blood serotonin levels, however, primarily indicate the serotonin circulating in the bloodstream. Urine measurement can provide a broader picture of serotonin metabolism, while blood levels are more specific to its immediate availability in the body.

What Other Factors That Can Cause Depression?

  • Deficiencies in folic acid/B12
  • Hypothyroidism
  • Heavy metal toxicity
  • Drug poisoning
  • Dementia, Pellagra
  • Sleep deprivation, Porphyria
  • Low blood sugar, Chronic Candida overgrowth
  • Sensitivity to wheat gluten
  • Essential fatty acid deficiency
  • Histamine imbalances (low or high)
  • Dopamine, Prolactin, Histidine, Serine imbalances
  • Conditions like Wilson’s disease, Brain allergies, Huntington’s disease, Endorphin imbalance

How Do You Increase Your Serotonin Levels Naturally?

To naturally increase serotonin levels, a balanced diet is key, particularly foods rich in tryptophan like turkey, eggs, cheese, and nuts. Regular exercise also boosts serotonin production. Exposure to sunlight can raise serotonin levels, as can stress management techniques like mindfulness or yoga. Adequate sleep is essential for regulating serotonin. Additionally, supplements like 5-HTP (5-Hydroxytryptophan) can help. 5-HTP, derived from tryptophan, is a precursor to serotonin and can support its production in the body.
