L-tryptophan is an essential amino acid and is the early form of all serotonin (a polypeptide neurotransmitter). Migraine sufferers usually have insufficient serotonin levels, which are known to cause migraines. However, serotonin cannot be obtained through nutritional supplements because it cannot enter the brain (where it is needed) through the blood-brain barrier. However, studies by L-tryptophan manufacturers have found that eating more foods rich in L-tryptophan can increase serotonin levels and help relieve migraines.

L-tryptophan manufacturers know that L-tryptophan-rich foods include spirulina, cod, peas, soybeans, fish, egg whites, turkey, cheese, tofu, sesame, avocado and various beans. The conversion and metabolism of L-tryptophan to serotonin has three stages, and the body can be helped by proper levels of vitamin B3 and B6. The molecule of L-tryptophan is very large, so its decomposition and absorption is not as easy as the small molecule amino acid. Most amino acids are converted from sugar molecules. We should increase carbohydrate intake through food. This will provide more transport channels for tryptophan molecules and reduce competition between other amino acid molecules and the absorption of tryptophan.

Increasing carbohydrates should not depend on increasing sugar intake, but should be too moderate to increase brown rice, bran bread, oats and potatoes. L-tryptophan manufacturers reminded that refined sugar should not be used as a diet to treat migraines, even if it is used, it should be used in small doses.
