How Long Does L-Tyrosine Take To Work? (For Improving Mood)

Are you feeling depressed?

Are your thyroid hormones unbalanced?

Do you wish you were mentally sharper?

Do you wish you could exercise for longer?

Well, if you answered yes to any of the above, there’s an impressive amino acid out there called L-Tyrosine which may be able to help.

Now, the interesting thing about L-Tyrosine is that the time it takes to work depends on which benefit you’re wanting to see.

I.e., if you’re taking L-Tyrosine to help balance your thyroid hormones, then you might need to take it for longer than if you were taking it to improve your mood.

So in this article, we cover the time it takes for L-Tyrosine to work for many different benefits.

With this information, you can then take L-Tyrosine for the amount of time required for the specific benefit you’re wanting to see.

Let’s get started.

What is L-Tyrosine?

L-Tyrosine is a naturally produced amino acid that’s derived from another amino acid called phenylalanine.

It’s found in various protein-rich foods, like fish, chicken, turkey, and cheese.

(Fun fact: Tyros means Cheese in Greek.)

L-Tyrosine helps your body produce important neurotransmitters like:

  • Serotonin
  • Dopamine
  • Adrenaline

It’s a boost in these neurotransmitters that provides many of the benefits that L-Tyrosine has to offer.

How long does L-Tyrosine take to work for improving mood?

What the science says

In one study, 12 patients with dopamine-dependent depression (DDD) were given 3,200mg of L-Tyrosine each day for 9 days.

On the very first day of treatment, an improved mood was observed in the subjects.

Interestingly, the subjects showed improvements in sleep too.

Vitalized Future’s thoughts

Based off the above study, you can expect L-Tyrosine to improve your mood within a day of taking it.

But just to be clear, this study was done in patients with DDD which is a specific form of depression.

Depression is usually tricky to treat as there are various forms and underlying causes.

So, there is a chance that L-Tyrosine won’t improve your mood.

How long does L-Tyrosine take to work for boosting exercise endurance?

What the science says

In one study, 8 cyclists drank either an L-Tyrosine drink or a placebo drink an hour before a cycle test.

According to the results, those who consumed the L-Tyrosine drink could cycle for 11 minutes longer on average than those who consumed the placebo drink.

It’s believed that this increase in endurance is due to increased dopamine activity, which improves exercise tolerance in the heat.

Vitalized Future’s thoughts

So looking at the above study, you can expect L-Tyrosine to improve exercise endurance after an hour of taking it.

How long does L-Tyrosine take to work for balancing thyroid hormones?

What the science says

In one study, 42 participants took either 12g of L-Tyrosine, a T3-T4 supplement, or a placebo each day for 138 days.

The results showed that the L-Tyrosine increased T3 by 6% and decreased TSH by 28%.

(High levels of TSH are linked with stress and hypothyroidism.)

Interestingly, they also reported a 47% improvement in mood.

Vitalized Future’s thoughts

Going purely off the study above, you can expect L-Tyrosine to help balance your thyroid hormones after taking it for 138 days.

But since we’re all biologically different, it may take less or more time depending on your current hormone status.

How long does L-Tyrosine take to work for improving mental function?

What the science says

In one study, 21 cadets took either 10g of L-Tyrosine (split into 5 doses) or a placebo each day for 6 days.

According to the results, those who took the L-Tyrosine performed better on a memory task and a tracking task than those who took the placebo.

Vitalized Future’s thoughts

So based off the study above, you can expect L-Tyrosine to help improve mental function after taking it for 6 days.

But many users report feeling mentally sharper within hours of taking L-Tyrosine.

Conclusion

L-Tyrosine is an awesome supplement that offers such a wide range of benefits.

But depending on what you’re taking it for, you may need to take L-Tyrosine for less or more time than you originally thought.

When taking supplements, lots of people expect to see overnight results. But truthfully, it takes time for your body to adapt and feel the full benefits.

And so, the key to success with supplements is patience.

Thanks for staying to the end of this article and I look forward to seeing you in the next one.
