L-Tyrosine Review

Editor's Review: 4.1 / 5.0

What you should know

L-Tyrosine is an amino acid that is not essential to the body however it is important to the structure of many proteins within the body. This ingredient has been reported to have weight loss properties, but some medical websites suggest that potency will be lost when this is added to a supplement.

Many so called fat burners will contain this substance in some way, shape or form and it has been reported that it can prove beneficial to those who are looking to lose weight and because it is a precursor to a thyroid hormone called thyroxine. This hormone and supplementation with L-Tyrosine apparently has the potential to increase your body’s natural metabolic rate.

Ingredients

Although L-Tyrosine is an ingredient commonly found in many fat burners it can be bought as a supplement on its own. This can be purchased online pretty cheaply. When purchasing weight loss supplements and other products online it is recommended that they are purchased from reputable stores and the ingredients are thoroughly checked out.

Product Features

L-Tyrosine is a precursor to a specific hormone which has been reported to have a positive effect on those that are planning to lose weight. However, clinical and scientific studies have not taken place to either prove nor disprove the statement and therefore there may be better weight loss supplements on the market.

It has been advised on certain websites that this is not something that should be supplemented in the body and therefore choosing this weight loss product should be considered thoroughly before an appropriate purchasing decision has been made.

Advantages

  • L-Tyrosine may help increase your bodies metabolism which may make it easier to lose weight.
  • Some studies suggest that L-Tyrosine may help improve your mood but only very slightly and only if you are in a stressful situation already.

Disadvantages

  • This ingredient may not do very much for many people.
  • Clinical studies on this ingredient are inconclusive.

Conclusion

L-Tyrosine is a very common ingredient that can be found in many different supplements for weight loss, mental health, and even bodybuilding. There are many studies about this ingredient on the Internet that claim this ingredient will help lose “stress-related” weight but it’s not clear how well it works.

L-Tyrosine is completely safe for people to take so we don’t really mind that it is included in so many supplements. If it does help you lose a little extra weight here and there, that’s just fine.

We wouldn’t recommend a weight loss program based around L-Tyrosine supplements on their own but see no harm in this ingredient being already inside a well known, proven weight loss supplement.

    Can I stop taking my Adderall XR (dextroamphetamine – generic) 20 mg. capsules – 2 daily and take L-Tyrosine instead without any adverse effects?

    Thank you for the information. I found it helpful. I thought you might want to know that there’s an error in this sentence in the second paragraph: “This hormone and supplementation with L-Tyrosine apparently has the potential to increase your bodies natural metabolic rate.” – ‘bodies’ should be body’s. –Linda

    My son is ADHD, moody and impulsive. Will he benefit from L-Tyrosine?

    ADD and ADHD are regular tendencies of kids. The people who write the DSM manual are paid by drug companies to create new ‘disorders’ in order to sell more drugs. That book will grow until its disorders cover every range of normal human behavior. They want us all on drugs. Get your kid off the pills and be a better parent.

    Don’t listen to bob. He is uneducated about ADD or he’d know better. Get the book “Healing ADD” by Daniel Amen. Make sure you read the intro. It covers the 6 types of ADD and the parts of the brain affected. It also talks about changes in diet and exercise and supplements that can be effective. I have a husband, son and grandson with ADD. This book has incredible information in it. Good Luck!

    How does l-tyrosine interact with thyroxine that is in synthroid? Can it take the place of synthroid? Is it safe to take them together?
