What exactly is L-tyrosine?
It is an amino acid, which means it is a building block of proteins. Your body produces it from phenylalanine and uses it as a raw material for thyroid hormones and the skin pigment melanin, among other things.

This capsule contains 750mg of l-tyrosine, one and a half times as much as Now's standard capsule. That means fewer capsules to swallow when you need higher doses. The capsule is made of plant-based cellulose, so it is also suitable if you are vegetarian or vegan.
L-tyrosine is one of the conditionally essential amino acids. Your body makes it itself from phenylalanine, an amino acid that you must obtain from food. You also get tyrosine from high-protein foods such as Parmesan cheese, chicken, fish, tofu, eggs, and pumpkin seeds. Cheese is at the top of that list for a reason. Tyros is Greek for cheese, and in 1846, German chemist Justus von Liebig first extracted tyrosine from casein, the protein in cheese. With a capsule, you know exactly how much you are taking, regardless of what is on your plate that day.
In your body, tyrosine is the starting point for thyroid hormones and melanin, the pigment in your skin and hair, among other things. Now recommends taking the capsule between meals.
With 750mg capsules, the label recommendation of 1 to 3 capsules puts you between 750 and 2250mg per day. For 1500mg, you need 2 capsules instead of 3. The bottle contains 90 pieces, enough for 30 to 90 days. Many people wonder whether it is better to take a high dose at once or spread it throughout the day. The label leaves this open, as long as you do not exceed 3 capsules, so spreading it over morning and afternoon is a great option. In short: the same free form of l-tyrosine as in the 500mg version, but more concentrated per capsule and in a plant-based capsule.
While the 500mg variant uses a gelatin capsule, Now opts for cellulose here. The filling consists of l-tyrosine with a little rice flour, silicon dioxide, and plant-based stearic acid, so that the powder is evenly distributed across each capsule. Now makes the capsules without wheat, gluten, soy, milk, egg, fish, shellfish, or nuts. The American company has been around since 1968 and tests raw materials and finished products in its own laboratories. This way, Now checks every batch to ensure that there really is 750mg of tyrosine in the capsule and that the powder is free from unwanted substances.
Those who already know that they need higher doses of tyrosine have fewer capsules to swallow with these. And those who eat plant-based do not have to compromise on the dosage.
One and a half times the standard 500mg capsule. For 1500mg per day, you take 2 instead of 3.
Suitable for vegetarians and vegans. The filling also contains no animal-derived ingredients.
The label allows 1 to 3 capsules per day. This way you can choose your own daily dose between 750 and 2250mg.
The amino acid is free and not bound in a protein chain.

It is an amino acid, which means it is a building block of proteins. Your body produces it from phenylalanine and uses it as a raw material for thyroid hormones and the skin pigment melanin, among other things.
The label recommends 1 to 3 capsules per day, which is equivalent to 750 to 2250 mg. Feel free to start with 1 capsule and do not exceed 3.
Preferably yes, between meals. This is how Now recommends it on the label.
750mg falls within the label recommendation of a maximum of 3 capsules per day. If you want to start with a lower dose, the 500mg version from Now is an alternative. If you have a thyroid condition or melanoma, or use MAO inhibitors, always consult your doctor first.
An enzyme converts tyrosine into L-DOPA, which is then converted into dopamine. Your body then converts dopamine into noradrenaline and adrenaline. In addition, your thyroid gland attaches iodine to tyrosine to produce the hormones T3 and T4.
N-acetyl-L-tyrosine (NALT) dissolves better in water, but your body only converts a small portion of it into tyrosine. A large part leaves your body unchanged through your urine. That is why many people choose the free form, as in this capsule.
