Best Phenylalanine

L-phenylalanine – or phenylalanine – is an essential amino acid that we must obtain from diet and supplements as it’s not made by the body.

Amino acids are vital for good health, and we need a constant supply to thrive. They’re building blocks for the proteins that make up our cells, tissues, hormones and brain chemicals.

Phenylalanine comes in three different forms:

  • L-phenylalanine – the active form found in food and the body
  • D-phenylalanine – a man-made supplemental form with a structure that’s the mirror image of L-phenylalanine
  • DL-phenylalanine – a mixture of equal amounts L- and D-phenylalanine

L-phenylalanine – or phenylalanine – is an essential amino acid that we must obtain from diet and supplements as it’s not made by the body.

Signs of L-phenylalanine Deficiency

If you don’t get enough of this amino acid, you may experience:

  • Fatigue
  • Low mood
  • Poor memory and concentration
  • Reduced appetite
  • Confusion

For those with higher protein requirements – athletes or bodybuilders – and those who might be prone to a deficiency – vegans or people with digestive disorders – a phenylalanine supplement is a great option. /p>

L-phenylalanine Health Benefits

Encourages Muscle Building and Fat Burning

L-phenylalanine supports healthy body composition in a few ways. As a building block required for protein synthesis, it repairs muscle damage that occurs during intense exercise and encourages healthy muscle building.

Interestingly, a 2017 study on active males found that 3g of phenylalanine taken 30 minutes before cycling significantly stimulated the fat burning process.

Improves Skin Health

L-phenylalanine used topically and internally, may improve the health and appearance of our skin. Our skin is our body’s largest organ, and how it looks can impact our confidence and how we interact with the world.

One study found that L-phenylalanine – along with UVA light – improved skin depigmentation, restoring pigment to areas more powerfully than UVA treatment alone.

Encourages Weight Loss

In addition to increased fat burning, L-phenylalanine may encourage healthy weight loss by stimulating the production of hormones that control appetite.

One study gave 10g of L-phenylalanine or a placebo to adults twenty minutes before a regular meal. They then tested levels of the hormone cholecystokinin (CCK) and assessed their appetite. It found that those who took the amino acid ate fewer calories and had higher levels of CCK which contributed to greater feelings of satiety (fullness).

Research has shown that phenylalanine is useful for controlling the increase in appetite and calorie consumption that women experience at certain times during the menstrual cycle.

Regulates Mood

Phenylalanine may be most popular as a potent mood-booster. This is because it is used for building neurotransmitters – hormones in the brain that transmit signals from one nerve cell to another. Generating healthy levels of these neurotransmitters is wonderful for our mental wellness.

L-phenylalanine is an essential precursor to an amino acid called tyrosine. Tyrosine is then converted into norepinephrine and the “feel-good” neurotransmitter dopamine. Norepinephrine – a short-term stress hormone – plays a role in mood regulation, and dopamine is involved in the brain’s reward center. Dopamine promotes feelings of happiness, pleasure and motivation, and assists with learning too.

Studies have found that supplementing with phenylalanine – alone or alongside conventional antidepressant medication – can significantly improve mood, calm anxiety and reduce agitation in the majority of subjects.

L-phenylalanine Precautions

People with a genetic condition called phenylketonuria (PKU) should avoid L-phenylalanine. PKU prevents the body from processing phenylalanine properly, causing a build-up in the blood that affects physical and mental development.
