The effects of drugs such as cocaine, nicotine or amphetamines are, directly or indirectly, related to an increase of dopamine levels in the brain. But you shouldn’t be a drug addict to boost your dopamine level. You can do it naturally. Since dopamine is synthesized from tyrosine, an amino acid, you can simply eat foods rich in tyrosine – the best injection of the “hormone of happiness”.
Although dopamine is found in many types of food, it is incapable of crossing the blood–brain barrier that surrounds and protects the brain. Therefore, it must be synthesized inside the brain from the building blocks – amino acids phenylalanine and tyrosine (with tyrosine being the most common).
Eating protein is a great way to stimulate dopamine production in the brain. There are plenty of food sources rich in tyrosine and phenylalanine that your brain needs in order to create dopamine, but grass-fed meats and wild-caught fish are the best of the best.
The recommended daily intake for phenylalanine and tyrosine is 25mg per kilogram of body weight, or 11mg per pound.
High tyrosine foods include cheese, soybeans, beef, lamb, pork, fish, chicken, nuts, seeds, eggs, dairy, beans, and whole grains.
