Tyrosine

How does Tyrosine work?

The body uses tyrosine to make chemical messengers that are involved in conditions involving the brain such as mental alertness.

Are there safety concerns?

Tyrosine is LIKELY SAFE when taken by mouth in food amounts and POSSIBLY SAFE when taken by adults short-term in medicinal amounts or when applied to the skin. Tyrosine seems to be safe when used in doses up to 150 mg/kg per day for up to 3 months. Some people experience side effects such as nausea, headache, fatigue, heartburn, and joint pain.

There isn't enough information available to know if tyrosine is safe for children to use in medicinal amounts. Don't give it to children without the advice of your healthcare provider until more is known.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There isn't enough information available to know if tyrosine is safe to use during pregnancy and breast-feeding. Stay on the safe side and avoid use.

Overactive thyroid (hyperthyroidism) or Graves disease: The body uses tyrosine to make thyroxine, a thyroid hormone. Taking extra tyrosine might increase thyroxine levels too much, making hyperthyroidism and Graves disease worse. If you have one of these conditions, don't take tyrosine supplements.
