{"product_id":"l-tyrosine","title":"L-Tyrosine - Cognitive Support Supplement","description":"\u003cp\u003eWhen the workload piles up and your mind still needs to perform, L-TYROSINE gives you targeted nutritional support for demanding days. Each serving delivers a substantial 1000 mg of L-Tyrosine, an amino acid used by the body in the production of key neurotransmitters involved in normal cognitive function. Built for long hours, intense focus and high-output environments, it is a strong addition for ambitious professionals and athletes who want to support mental performance when the pressure rises.\u003c\/p\u003e\n\n\u003cp\u003eThe body uses L-Tyrosine as a substrate in the catecholamine pathway. Tyrosine is converted to L-DOPA by the enzyme tyrosine hydroxylase, and from there to dopamine, noradrenaline and adrenaline. That first conversion is the rate-limiting step and is tightly regulated, so supplemental L-Tyrosine contributes to the available substrate pool rather than driving output directly. L-Tyrosine also shares its transport route across the blood-brain barrier with other large neutral amino acids, which is why the label positions it away from a protein-rich meal.\u003c\/p\u003e\n\u003cp\u003eThis is a product for healthy adults 18 years and older who want a straightforward amino acid supplement as part of a morning routine. The label's suggested use is two capsules on an empty stomach, 30 to 45 minutes before breakfast, which places it ahead of a cognitively or physically demanding day rather than at any point in it. For heavier days the label also sets out an enhanced option of two capsules twice daily. Thirty servings per container covers a month at the standard serving.\u003c\/p\u003e\n\u003cp\u003eContains L-Tyrosine — account for total daily intake if combining. Mito-Focus Xtreme carries L-Tyrosine as one of several stacked actives, so read both labels and add up the total before taking them together.\u003c\/p\u003e\n\n\u003cp\u003e\u003cem\u003eThe following describes published research on the ingredient. It is not a claim about this specific product.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003eStudies suggest that the measured effects of L-Tyrosine depend heavily on the dose used and on how demanding the task is. Colzato and colleagues (2013, Frontiers in Behavioral Neuroscience) gave 22 healthy adults a single 2000 mg dose — twice this product's 1000 mg serving — and recorded better performance on the demanding 2-back working-memory condition than placebo, with no difference on the easier 1-back condition. Thomas and colleagues (1999, Pharmacology Biochemistry and Behavior) gave 20 adults 150 mg per kg of body weight one hour before a multitasking battery, which is roughly 10 500 mg for a 70 kg adult, or about ten times a single serving here, and reported higher accuracy on the working-memory component than placebo. Shurtleff and colleagues (1994) used the same 150 mg per kg dose with eight adults tested in a room cooled from 22°C to 4°C, and recorded faster response times and more correct answers on a delayed matching-to-sample task than placebo under the same cold condition, with no further change in the warm condition.\u003c\/p\u003e\n\u003cp\u003eResearch indicates the overall picture is mixed rather than uniform, and the honest reading includes the null results. Jongkees and colleagues (2015, Journal of Psychiatric Research) reviewed the cognitive literature and reported that results vary considerably between studies, with the clearer effects concentrated in short-term demanding conditions and little support for physical exercise outcomes. van de Rest and colleagues (2017) gave 17 adults aged 60 to 75 single doses of 100, 150 and 200 mg per kg and found that load-dependent working-memory accuracy went down as the dose went up. In the Shurtleff study, measured plasma noradrenaline did not change at all, despite plasma tyrosine rising from about 56 nmol\/L to between 140 and 168 nmol\/L within 90 minutes, and no significant effect on heart rate has been recorded across this literature.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eL-Tyrosine compared with N-Acetyl L-Tyrosine.\u003c\/strong\u003e N-Acetyl L-Tyrosine, or NALT, is L-Tyrosine with an acetyl group attached, which makes it markedly more soluble in water. That solubility is genuinely useful in liquid products, but it is often presented as better absorption, and the available human data does not support that reading. Magnusson and colleagues (1989) found that intravenous NALT raised L-tyrosine concentrations by only about 20 percent despite much larger rises in NALT itself, with 56 percent of the dose excreted within four hours, and Hoffer and colleagues (2003) reported roughly 35 percent of a parenteral dose excreted unchanged. This product uses free-form L-Tyrosine, which is the form used in the human cognitive studies cited above.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eL-Tyrosine compared with L-Phenylalanine.\u003c\/strong\u003e L-Phenylalanine sits one step further back in the same pathway: the body converts it to L-Tyrosine using the enzyme phenylalanine hydroxylase. Supplementing L-Tyrosine starts from the next molecule along, so no conversion step is required first. Both compete with other large neutral amino acids for the same transport route, which is why timing away from a protein-rich meal applies to either.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eL-Tyrosine compared with L-Theanine.\u003c\/strong\u003e These are two different amino acids doing two different things. L-Theanine is found in tea leaves and does not enter the catecholamine pathway at all, while L-Tyrosine is the direct precursor within it. They are not substitutes for one another, and they are commonly used at different points in the day.\u003c\/p\u003e\n\n\u003ch2\u003eKey Benefits\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDeclared 1000 mg serving:\u003c\/strong\u003e Two capsules provide 1000 mg of L-Tyrosine, with 500 mg stated per capsule.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle amino acid ingredient:\u003c\/strong\u003e L-Tyrosine is the only active.

MitoGenix L-Tyrosine provides 1000 mg per two-capsule serving as a single ingredient.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow much L-Tyrosine should I take daily?\u003c\/strong\u003e\u003cbr\u003eThe standard serving is two capsules daily, providing 1000 mg of L-Tyrosine. For heavier days the label sets out an enhanced use of two capsules twice daily. Do not exceed the recommended dose, and count L-Tyrosine from any other product you take.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhen is the best time to take L-Tyrosine?\u003c\/strong\u003e\u003cbr\u003eTake two capsules on an empty stomach, 30 to 45 minutes before breakfast, as the label directs. L-Tyrosine shares a transport route with other amino acids from protein, so taking it away from a protein-rich meal leaves less competition for that route.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow long does L-Tyrosine take to work?\u003c\/strong\u003e\u003cbr\u003eBlood tyrosine rises within about 30 minutes of a dose and peaks at around two hours, and research gives it 15 to 60 minutes before testing. Individual response varies, so no onset time is promised; take it before breakfast as directed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan L-Tyrosine support focus during demanding work?\u003c\/strong\u003e\u003cbr\u003eL-Tyrosine is chosen to support focus when the day is demanding. In a 2013 study, 22 healthy adults given 2000 mg, twice this product's serving, did better on a demanding working-memory task than with placebo, although results across studies vary.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs L-Tyrosine safe to take every day?\u003c\/strong\u003e\u003cbr\u003eMitoGenix L-Tyrosine is directed for daily use. Reference sources describe it as well tolerated in short-term use of up to three months, while long-term data is limited. It is not intended for anyone under 18 or for pregnant or breastfeeding mothers.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat are the side effects of L-Tyrosine?\u003c\/strong\u003e\u003cbr\u003eMost studies report no adverse effects, but some people report nausea, headache or heartburn. Take no more than the recommended dose, and discontinue use if any adverse reactions occur. Anyone with a known medical condition should consult a healthcare professional before use.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eL-Tyrosine vs N-Acetyl L-Tyrosine: which is better?\u003c\/strong\u003e\u003cbr\u003eN-Acetyl L-Tyrosine dissolves more easily in water, but in one human study it raised blood tyrosine by only about 20 percent, with over half excreted within four hours. MitoGenix uses free-form L-Tyrosine, the form used in the human studies cited on this page.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I take L-Tyrosine with coffee?\u003c\/strong\u003e\u003cbr\u003eThe label sets no restriction on coffee, but L-Tyrosine is described as stimulatory, and many pre-workout products already contain tyrosine or caffeine. Read every label, keep your total intake in check, and take MitoGenix L-Tyrosine as directed before breakfast.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I take L-Tyrosine with medication or other supplements?\u003c\/strong\u003e\u003cbr\u003eSpeak to a healthcare professional first. Reference sources note interactions with MAO inhibitors, thyroid medication and levodopa, which should be taken at least two hours apart from L-Tyrosine. Mito-Focus Xtreme contains L-Tyrosine, so account for total daily intake if combining.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I take L-Tyrosine with L-Theanine?\u003c\/strong\u003e\u003cbr\u003eYes. They share no active ingredient, so there is nothing to add up across the two labels. MitoGenix L-Tyrosine is taken before breakfast, while MitoGenix L-Theanine can be taken early in the day or in the evening, so the two fit different parts of your routine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat makes a good quality L-Tyrosine supplement?\u003c\/strong\u003e\u003cbr\u003eLook for the amount declared per capsule, a single active ingredient and no proprietary blend. MitoGenix L-Tyrosine declares 500 mg per capsule and 1000 mg per serving, uses free-form L-Tyrosine, and is independently tested for identity and purity.\u003c\/p\u003e\n\n\u003cp\u003e\u003csmall\u003e\u003cstrong\u003eCAUTION:\u003c\/strong\u003e Store in a cool, dry place or below 25°C.
