I’ve spent quite some time researching amino acids due to their popularity in sports nutrition.
Recently, amino acids have been growing in popularity in the nootropic industry as well.
And phenylalanine is not an exception.
Phenylalanine is an amino acid that exists in 3 forms: D-phenylalanine, L-phenylalanine, and the laboratory mix called DL-phenylalanine. 
While L-phenylalanine is an essential amino acid, this is not true for D-phenylalanine.
Primary dietary sources of L-phenylalanine include meat, eggs, cheese, fish, eggs, cheese, and milk.
The main question is: What’s the primary function of phenylalanine? And does supplementing it provides any benefits?
Let’s learn more.
Let’s try to understand the main benefits of this exciting amino acid.
You might be surprised.
1. Phenylalanine Is Crucial For Normal Body Functioning
First of all, L-Phenylalanine is an essential amino acid, which means it is crucial for normal body functioning. 
But not just that, this amino acid participates in the production of:
- Tyrosine (another amino acid)
- Epinephrine and norepinephrine
So, if we don’t get enough of this amino acid in our body, we might encounter health issues.
That’s why supplementing it quickly solves this issue.
2. Phenylalanine And Depression
Some studies have found that supplementing DL-Phenylalanine might be an effective antidepressant.
One study was done on 20 individuals, and 12 of them needed no further treatment after giving them 75-200 mg of this supplement for 20 days. 
While further studies have to be done, DL-Phenylalanine shows some potential.
3. Other Benefits Of Phenylalanine
A few other studies have been of supplementing Phenylalanine, but they showed mixed results.
- Phenylalanine may help alleviate symptoms of alcohol withdrawal, but results are mixed 
- D-Phenylalanine might help with pain relief 
Other studies (on ADHD and Parkinson’s disease) showed no real benefits of supplementing Phenylalanine.
L-Phenylalanine vs D-Phenylalanine vs DL-Phenylalanine
To make it clear for you, let’s try to understand the main difference between all three types of Phenylalanine.
As I mentioned before, L-Phenylalanine is an essential amino acid that you get from food. Then it is converted to L-Tyrosine and from there to L-Dopa.
D-Phenylalanine is a synthetic version, created in the lab. Even though it mirrors L-Phenylalanine, it has a different working mechanism.
So, how about DL-Phenylalanine?
Well, DL-Phenylalanine is a mixture of both, L- and D-Phenylalanine.
It is believed that this mix should get the best out of both types of the amino acid. However, more studies have to be done to confirm that.
Phenylalanine In Food
Supplementing phenylalanine sounds like a great idea, but what if you want to get it from food?
Which food sources contain the most of this amino acid?
Many foods contain phenylalanine, so you can get it from both plant and animal products.
Soy products are a great source, and if you eat animal products, then eggs, seafood, and cheese contain a lot of it. 
If you work out a lot, and you drink proteins, then soy proteins are your go-to supplement.
The consensus is that you should eat a variety of protein foods and that’s how you’ll get enough of it in your body.
However, supplementing can help you reach the recommended daily dose.

Phenylalanine Side Effects
Is phenylalanine safe? How about the side effects?
Since phenylalanine is an essential amino acid, it is of course recognized as a safe compound by the FDA. 
When phenylalanine is supplemented as recommended (more info follows below), then you should expect no side effects.
However, high concentrations can cause brain and metabolism issues.
Also, it’s not recommended supplementing phenylalanine if you are pregnant.
So, to make a sum, do follow the daily recommended dosage, and this amino acid should cause no issues whatsoever.
Phenylalanine Recommended Dosage
The recommended daily dosage of L-Phenylalanine is 3 times up to 500 mg.
Most tablets and capsules that are sold on the market contain around 500 mg of L-Phenylalanine per capsule/tablet.
However, you can also find some lower dosages, especially when this amino acid is combined with others.
Where To Buy Phenylalanine?
