One word about tryptophan
Tryptophan is an amino acid that’s linked to good quality sleep as it is a precursor to the sleep-inducing chemicals serotonin and melatonin, in the brain. For tryptophan to be effective it has to cross the blood-brain barrier where it competes for absorption which other amino acids. The problem comes in that the amount of Tryptophan in protein is normally a lot lower than the other amino acids it competes for absorption with. However, when we eat carbohydrates with protein the other proteins can be blocked by the insulin which is released, meaning that more Tryptophan is absorbed.
