4-(2-Aminoethyl)phenol, 4-Hydroxyphenethylamine, Tyramin, Tyramine hydrochloride.


Overview Information

Tyramine is a chemical that is found naturally in the human body. It is also made in the lab. Tyramine is found in foods that have gone bad or in foods or drinks that were made by fermenting bacteria, like beer, cheese, and tofu. Some dietary supplements contain tyramine.

Tyramine is used for weight loss and athletic performance, but there is no good scientific evidence to support these uses.

How does it work?

Tyramine is a chemical in the body that helps the brain and nervous system function normally. High levels of tyramine can cause blood vessels to tighten, which increases blood pressure. There isn't enough reliable information to know how tyramine supplements might work.

Uses & Effectiveness?

Insufficient Evidence for

  • Athletic performance.
  • Weight loss.
  • As a stimulant.
  • For increased focus.
  • Other uses.
More evidence is needed to rate the effectiveness of tyramine for these uses.
Side Effects

Side Effects & Safety

When taken by mouth: Tyramine is POSSIBLY SAFE when eaten as part of a normal meal. Meals that contain no more than 600 mg of tyramine are considered safe for most people. However, eating a meal that contains more than 600 mg of tyramine is POSSIBLY UNSAFE. This amount of tyramine might increase the risk for adverse effects, including high blood pressure and headache.

There isn't enough reliable information to know if tyramine supplements are safe to take in any dose.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There isn't enough reliable information to know if tyramine is safe to use when pregnant or breast-feeding. Stay on the safe side and avoid use.

Disease in the stomach and intestines: If people have damage in their intestines, they might absorb more tyramine into the body. This might increase the side effects of tyramine. Don't take tyramine if you have a disease like Crohn disease, ulcerative colitis, or celiac disease.

High blood pressure: Tyramine might increase blood pressure. Taking tyramine might make high blood pressure worse.

Migraine headaches: Taking tyramine might cause migraine headaches, especially in people who suffer from migraines. Don't take tyramine if you get migraines.

Surgery: Tyramine might increase blood pressure. In theory, taking tyramine might interfere with surgery by increasing blood pressure. Stop taking tyramine at least 2 weeks before surgery.



We currently have no information for TYRAMINE Interactions.



The appropriate dose of tyramine depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for tyramine. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
