Bird’s nest is reputed to promote healthy growth to the fetus by stimulating cell growth, improving blood supply and strengthening the immune system. It is rich in glycoprotein and amino acids that are the building blocks of cells. The richness of collagen also helps to relieve stretch marks during pregnancy and allows the mother to recover her smooth complexion after giving birth. Tryptophan (a precursor of serotonin and melatonin) reduces fatigue, anxiety, and stress in mothers. It enhances the mother’s recuperation after birth and aids in growth for the child.
