If you have high blood pressure (hypertension), it's important to understand how certain substances in your diet and supplements can affect your condition. This article will explain the connection between tyrosine, tyramine, and your blood pressure.
What is Tyrosine?
Tyrosine is a natural substance called an amino acid. Your body uses it to make important chemicals, including:
Dopamine: A chemical that helps with mood and movement.
Norepinephrine and Epinephrine (Adrenaline): Chemicals that can increase your heart rate and blood pressure.
You get tyrosine from protein in your diet, and it's also available as a supplement.
What is Tyramine?
Tyramine is another natural substance that comes from tyrosine. It's formed when foods are:
Aged (like cheese)
Fermented (like sauerkraut)
Cured (like some meats)
Tyramine can cause blood vessels to narrow, which can raise blood pressure.
How Your Body Normally Handles Tyramine
In most people, the body has a system to break down tyramine quickly. This system involves special substances called enzymes, specifically:
Monoamine Oxidase (MAO): These enzymes act like "Pac-Men," gobbling up tyramine and preventing it from causing a big increase in blood pressure.
The Problem with Certain Medications
Some medications, called Monoamine Oxidase Inhibitors (MAOIs), interfere with the MAO enzymes. If you take an MAOI, your body can't break down tyramine as efficiently. This can lead to a dangerous buildup of tyramine in your blood, causing a sudden and severe rise in blood pressure, called a hypertensive crisis. This is a serious medical emergency.
Tyrosine Supplements and Blood Pressure
Now, what about tyrosine supplements?
For most people with high blood pressure who are NOT taking MAOIs: Tyrosine supplements are generally not a major concern. Your body can usually handle the small amount of extra tyramine that might be produced.
For people with high blood pressure who ARE taking MAOIs: Tyrosine supplements are likely dangerous. They can significantly increase the risk of a hypertensive crisis.
Important Considerations for People with High Blood Pressure
If you are taking MAOIs:
Avoid tyrosine supplements.
Follow your doctor's instructions carefully about foods to avoid (those high in tyramine).
If you are not taking MAOIs:
Talk to your doctor before taking any new supplements, including tyrosine. While it's generally considered safe, it's always best to be cautious, especially if you have a medical condition.
Be aware that some people may be more sensitive to tyramine than others. If you notice any changes in your blood pressure or experience headaches after taking tyrosine supplements, stop taking them and consult your doctor.
Key Takeaway
While tyrosine is a natural substance, it's important to be aware of its potential effects on blood pressure, especially if you have hypertension or are taking MAOIs. Always consult your doctor before starting any new supplements.
