Helps to decrease cognitive fatigue due to physically stressful situations (e.g. extended wakefulness, exposure to cold, excessive noise).

Your body can build it from another amino acid, phenylalanine, which is why it is counted as non-essential. It is found in protein foods such as cheese, chicken, fish, eggs, soy and beans.\u003c\/p\u003e\n\u003cp\u003eThe licence lists L-tyrosine as the only ingredient. The tub holds plain free-form L-tyrosine, with no fillers, sweeteners or flavours.\u003c\/p\u003e\n\u003ch2\u003ePowder or capsules\u003c\/h2\u003e\n\u003cp\u003eNatural Factors also makes L-Tyrosine 500 mg as a vegetarian capsule. One scoop of the powder equals ten of those capsules, so the powder is the practical choice for anyone following the 5 g label dose. Capsules make more sense if you only want a small amount or travel a lot.\u003c\/p\u003e\n\u003ch2\u003eHow to take it\u003c\/h2\u003e\n\u003cp\u003eAdults 18 and over take 1 scoop twice a day. Since tyrosine is the only ingredient, each scoop is about 5 g of powder. Consult a health care practitioner before use if you are pregnant or breastfeeding, and keep it out of the reach of children. The full directions and cautions are under How to Take.\u003c\/p\u003e\n\u003ch2\u003eWho it suits\u003c\/h2\u003e\n\u003cp\u003eAdults who face long shifts, cold work sites or loud surroundings and want a plain tyrosine powder they can measure themselves. It is a single-ingredient product, which keeps the label short for anyone tracking what they take. The tub format also lets you split a scoop if you want less than the label amount.\u003c\/p\u003e\n\u003ch2\u003eNatural Factors L-Tyrosine Powder FAQ\u003c\/h2\u003e\n\u003ch3\u003eHow much L-tyrosine is in each scoop?\u003c\/h3\u003e\n\u003cp\u003e5,000 mg, or 5 g.\u003c\/p\u003e\n\u003ch3\u003eHow long does the 250 g tub last?\u003c\/h3\u003e\n\u003cp\u003eAbout 25 days at the label dose of 1 scoop twice a day.\u003c\/p\u003e\n\u003ch3\u003eIs there anything else in the powder?\u003c\/h3\u003e\n\u003cp\u003eNo. L-tyrosine is the only ingredient listed.\u003c\/p\u003e\n\u003ch3\u003eWhat does the L in L-tyrosine mean?\u003c\/h3\u003e\n\u003cp\u003eIt names the natural form of the amino acid, the one built into the proteins in food.
