L-Tyrosine

Buy L-Tyrosine: an amino acid building block

L-Tyrosine is an amino acid that serves as a building block for proteins in the body. It is classified as a non-essential amino acid because the body can produce it itself from the amino acid phenylalanine. L-Tyrosine is popular as a standalone supplement, particularly among athletes, and is available in capsules, powder, and in combination with other nutrients. In our range, you will find L-Tyrosine in various dosages and package sizes.

What is L-Tyrosine?

L-Tyrosine is one of the amino acids that serve as a building block for proteins. It is called non-essential because the body can produce it itself from the essential amino acid phenylalanine. No official health claims have been approved for L-Tyrosine. L-Tyrosine for supplements is usually obtained through fermentation. The label states how much L-Tyrosine a product provides per serving.

L-Tyrosine and phenylalanine

L-Tyrosine and phenylalanine are closely related: the body produces L-Tyrosine from the essential amino acid phenylalanine. This means you get L-Tyrosine both directly through high-protein foods and through its production from phenylalanine. There are no approved health claims for L-Tyrosine. What makes a product suitable is primarily the dosage per serving and the form that suits your preference.

What foods contain L-Tyrosine?

L-Tyrosine occurs naturally in high-protein foods. Good sources include cheese and other dairy products, meat, fish, eggs, nuts (such as almonds), seeds, legumes, and soy products. The name tyrosine is even derived from the Greek word for cheese, in which the substance was first discovered. With a varied and sufficiently high-protein diet, most people get L-Tyrosine through food and through its production from phenylalanine. For those who want to supplement their intake in a targeted way, a supplement is a practical option.

What forms of L-Tyrosine are available?

L-Tyrosine is available in supplements as capsules and as a standalone powder. Capsules offer a fixed dosage per piece (for example, 650 mg), while powder makes the dosage flexible and is suitable for use by, for example, athletes. There is also N-acetyl-L-tyrosine (NALT), a form that is bonded to an acetyl group and is offered as being more soluble. You will also find L-Tyrosine in combination with other nutrients, such as biotin. When comparing, it is useful to pay attention to the amount of L-Tyrosine per serving and to the form.

How much L-Tyrosine to take per day and when?

No official recommended daily amount has been established for L-Tyrosine. The dosage varies per product and is stated on the packaging, expressed in milligrams or grams per serving. Many people take L-Tyrosine on an empty stomach because, as an amino acid, it then competes less with other amino acids from food, but the timing of intake is ultimately a matter of preference. Follow the instructions for use of the specific supplement and do not exceed the recommended dosage without advice. If you use medication (for example, thyroid medication) or have a thyroid condition, consult a doctor first. Advice is also advisable during pregnancy or breastfeeding and in case of doubt.

Buy L-Tyrosine: what to look for?

When choosing an L-Tyrosine supplement, there are a few practical points to consider. Look at the amount of L-Tyrosine per serving and at the form: pure L-Tyrosine (capsules or powder) or N-acetyl-L-tyrosine (NALT). Determine whether you are looking for a standalone amino acid or a combination, for example with biotin, and whether you prefer capsules or powder. Pay attention to the purity, whether the product is vegan, and to the price per daily serving. L-Tyrosine is an amino acid; for related products, also view our collection of Amino Acids.
