On the market, some manufacturers offer L-tryptophan together with 5-HTP. You should never exceed the daily amount, because an excess of serotonin can cause nausea, dizziness, dizziness and excessive sweating.
There are no side effects if you only get your L-tryptophan intake from food.
No side effects have been found for breastfeeding women either. In 2015, a study published in the Journal of European Neuropsychopharmacology showed that L-tryptophan supplements maintain normal L-tryptophan levels in breast milk. Therefore, there is no danger for the baby (13).
For pregnant women, however, it has not yet been established whether taking L-tryptophan supplements is safe. So it is best to talk to your doctor first or not to take L-tryptophan supplements.
