There’s a major controversy over whether or not depression is caused by low tryptophan and it’s consequence—low serotonin. Some researchers assert that there’s no support for the hypothesis that depression is caused by lowered serotonin. What does the science say about the causes of depression . . . Continue reading
Without tryptophan there would be no melatonin, the backbone of the biology of sleep. But tryptophan’s role in sleep might be more about how it is affected by things like diet, light exposure and gut health than it is about the tryptophan itself. Continue reading
Tryptophan can interact with drugs and supplements that cause sedation, increasing the sedative effect. Taking tryptophan with any of these drugs, substances or supplements might cause excessive sleepiness and negatively impact the ability to drive or operate heavy machinery. Continue reading

Given that dietary tryptophan play such a pivotal role in sleep, it might make sense that taking tryptophan supplements should improve sleep. But it’s just not as simple as popping a pill. Continue reading
Tryptophan plays a pivotal role in the gut-brain axis, a two-way biochemical conversation between our brains and bellies that helps determine the production of melatonin and serotonin, key brain chemicals that affect sleep and mood. Optimizing the biology of mood and sleep includes optimizing factors that impact tryptophan nutrition. Continue reading
The most potent way to get the sleep-promoting benefits of melatonin is to not to buy it off a store shelf. Natural melatonin is made in the body from food. All melatonin production is driven by key dietary nutrients, especially tryptophan found in foods like turkey, eggs and bananas. Continue reading
