Now Foods L-Tyrosine 500 mg – free-form amino acid in capsules

Now Foods L-Tyrosine is a food supplement providing 500 mg free-form L-tyrosine in every capsule. Free form means that the amino acid is not bound in proteins or peptides but is present in the capsule as a pure substance. The bottle contains 120 capsules. The manufacturer recommends taking 1 capsule one to three times daily, preferably between meals, so depending on use the bottle lasts 40–120 days. The composition is simple: besides L-tyrosine, the capsule contains only two excipients and the capsule shell. Such a short ingredient list suits those who want to know exactly what they are taking and prefer a single amino acid without additions.

What is L-tyrosine?

L-tyrosine is an aromatic amino acid, one of the twenty amino acids from which the body builds proteins. It is called conditionally indispensable because the body can make it from another amino acid, phenylalanine. In the diet, L-tyrosine is found in all protein-rich foods, for example cheese, cottage cheese, meat, fish, eggs, legumes and nuts.

The name of the amino acid comes from the Greek word tyros, meaning cheese: the German chemist Justus von Liebig first isolated tyrosine in 1846 from casein, the protein of cheese. Food supplements use the L-form, which is the same form that occurs naturally in food proteins.

How to use?

Take 1 capsule one to three times daily, preferably between meals, with a glass of water. The maximum daily amount is 3 capsules, i.e. 1500 mg L-tyrosine. Do not exceed the recommended daily amount. If you also use other food supplements containing L-tyrosine, for example amino acid blends, take their amounts into account. Taking one capsule a day, the bottle lasts 120 days; taking three capsules a day, 40 days.
