L Tyrosine Dosage

how much tyrosine to take

More commonly referred to as Tyrosine, L Tyrosine is a subset amino acid created in the human body as a result of the breakdown of phenylalanine.  Phenylalanine is a naturally occurring amino acid subsidized by common foods that we consume, meaning Tyrosine is also 100% natural and in no way synthetic.  At Vaxxen, we like to deal with the more organic and natural substances because the likelihood of long term, unknown side effects is considerably lower than when you deal with something created in Frankenstein’s laboratory.  In any case, it’s relatively common for humans to have phenylalanine deficiency problems so they supplement with Tyrosine, eliminating the need for breakdown entirely while still complying with the natural desires of their systems.  Let’s take a look at why WE would want extra Tyrosine and how much we should be taking for a dosage…

Why Use Tyrosine?

Tyrosine has been proven to be successful in the treatment of neurological disorders and diseases such as depressing, narcolepsy, and even stroke [1].  For a full list of the different reasons Tyrosine is prescribed to people, check out this article we wrote back in December.

What we care about is that Tyrosine is a precursor to a variety of other natural substances that have been linked to having a profound impact on weight loss in human beings.  Dopamine, norepinephrine, and epinephrine are all keep chemicals produced in our bodies that have positive effects on our abilities to lose or maintain weight.  Speeding up metabolic rates, staving off unnecessary hunger, and keeping us positive and focused during our weight loss campaigns are all the presumed work of increased levels of Tyrosine.

Can I Supplement Tyrosine Without A Prescription?

Absolutely!  There is no reason why you can’t try out Tyrosine as a supplement if you’re cutting weight or really hitting a wall when it comes to shedding the visceral fat deposits in the stubborn areas of your body [2].  The only people who should avoid supplementation are those who are pregnant and those who have been diagnosed with thyroid problems.  If you’re not pregnant and don’t have Graves disease or hyperthyroidism, there are no real side effects that you need to be aware of unless you’re really going to abuse dosage instructions.  Don’t.

How Much L Tyrosine Dosage Should I Take?

Ahhh… the reason you really kept reading this blog post to begin with.  The amount of Tyrosine you ingest as supplementation is going to differ from person to person.  If you’re already taking a pre-workout product like Fulcrum, then you probably are already supplementing and didn’t even know it.  In most cases, it’s suggested that you ingest between 500 and 1000mg of Tyrosine on a daily basis.  Try to split that up in 2 to 4 different supplement cocktails throughout your day, preferably before a half hour before you eat a small meal.  If you’re overweight, hug the 1000mg mark daily.  If you’re not really overweight but you’re just looking to cut a few extra pounds in your cutting cycle, hug the 500mg mark for daily consumption.  Be aware of any current supplements or blends you’re taking that already have Tyrosine so that you don’t accidentally abuse the dosage.
