发帖数: 7349 | 1 Tryptophan is an amino acid that's believed to induce sleep. This is because
it is a precursor to the sleep-inducing chemicals serotonin and melatonin,
in the brain. Tryptophan is present in small amounts in most protein foods
and in higher amounts in yoghurt, milk, oats, bananas, dates, poultry, eggs
and peanuts. |
