What is Tyrosine?
Tyrosine is a power amino acid, a building block of protein which is important for the body. It is naturally produced in the body from another amino acid called phenylalanine and makes several important substances to regulate the body’s functions.
Some of the substances that tyrosine makes include dopamine, adrenaline and noradrenaline, thyroid hormones, and melanin. Dopamine is a brain chemical that is important for memory and motor skills, while adrenaline and noradrenaline are hormones responsible for responding to stressful situations. Thyroid hormones regulate metabolism which is crucial for every process in the body. Melanin is the pigment that gives skin, hair, and eyes their color, but it is also protects the body from cancer.
Because tyrosine is a precursor to these substances, it may be effective in helping overweight and obese people lose weight. Theoretically, it controls stress which can lead to weight gain. Plus, it will help regulate metabolism which can expedite weight loss when combined with a nutrient-dense diet and exercise.
What are Tyrosine Effects on Body Fat?
To reduce body fat, tyrosine is beneficial in several ways. Let’s take a look at a few of the biggest benefits.
Tyrosine Controls Appetite
To resist the urge to eat requires proper functioning of certain brain chemicals such as dopamine which is made by tyrosine. When eating, the dopaminergic pathways regulate reward sensitivity. In other words, this pathway tells your body that it’s satisfied with what you’ve eaten and helps control your appetite. Studies have shown that obese people overeat to compensate for the deficits in the dopaminergic reward system. When treated with tyrosine, significantly lower levels of hunger occur.
Tyrosine Increases Metabolism
Low calorie diets tend to lower metabolic rate and cause weight plateaus. Tyrosine makes the hormone noradrenaline which increases heart rate. With increased blood flow, the body releases glucose (sugar) from energy stores at a faster rate. In addition, tyrosine makes thyroid hormones which regulate metabolism. A proper metabolism has a beneficial effect on body fat.
Tyrosine Improves Stress Levels
Tyrosine also helps stabilize the body when undergoing extreme stressful situations and promotes a sense of wellbeing. This is due to the increased levels of dopamine, noradrenaline, and adrenaline it makes which prevents some of the cognitive decline in response to physical stressors. Unfortunately, the stress hormone cortisol promotes body fat, especially in the abdominal region, and can make weight loss difficult. Cortisol levels are higher in dieters due to calorie-deficit meals, exercise, and less sleep. Tyrosine can help improve these stressors so that weight loss is successful.
Tyrosine Boosts Performance
Dopamine, created by tyrosine, improves brain function which includes mental alertness. Therefore, it’s reasonable to say that focus on training will increase.
What are Tyrosine Rich Foods?
Tyrosine may be obtained through several foods. Following is a list of tyrosine rich foods with the amount of tyrosine per 200 calorie servings.
Can I Take a Tyrosine Supplement?
You may take a tyrosine supplement in capsule form. However, it is better to be taken in a formula with Vitamin B6, folate, and copper for better conversion. Whether you take it in a stand-alone form or with a synergistic blend, just be sure that it is from a reputable company. The recommended dosage for tyrosine is 250 to 1,000 milligrams three time per day. Take it about 30 minutes before each meal. Following are a few high quality products that contain tyrosine. You may choose the one that best fits your needs.

Are Tyrosine Supplements Safe?
Tyrosine supplements are safe. However, you may want to check with your health practitioner or pharmacist before taking tyrosine, especially if you are pregnant/breastfeeding or take pharmaceutical drugs. Following are medications that should not be taken with tyrosine supplements.
Monamine Oxidase Inhibitors (MAOI) or Antidepressants
You should avoid taking tyrosine if you currently take Marplan, Nardil, Parante, and Selegiline. It may increase your blood pressure to dangerous levels which can lead to heart attack or stroke.
Thyroid Hormone Replacements
Tyrosine is a precursor to thyroid hormones. Taken with thyroid hormone replacement therapy, your thyroid levels may increase too much causing hyperthyroidism.
Used to treat Parkinson’s disease, tyrosine may interfere with how your body absorbs this medication.
The amino acid, tyrosine, may reduce body fat by controlling appetite, increase metabolism, improve stress levels, and boost training performance. However, this supplement is not appropriate for everyone. It is important to check with your practitioner or pharmacist to be sure tyrosine is right for you, especially if you are on any medications or have a medical condition.
