Certain fish and sea creatures contain sleep-inducing tryptophan, including shrimp, cod, tuna, and halibut. But since not all seafood choices are healthy for us (some are high in contaminants) or for the planet (many are overfished, or methods for catching them kill other species), stick to catches like Pacific cod from Alaska or pole-caught Albacore tuna from the U.S. or British Columbia.
If keeping track of the latest safe seafood guidelines is too complicated, you can get your tryptophan fix from other things. You’ve probably heard that warm milk can help you sleep, since milk contains tryptophan. But the key is to combine carbs with a protein containing tryptophan to help your body better utilize the sleep inducer. Try pairing a cup of whole grain cereal with organic milk before bedtime.
