Why Choose Source Naturals L-Phenylalanine?

The tablets are vegan-friendly and free from common allergens. With 500 mg per serving and 100 tablets per bottle, it's a reliable choice for daily amino acid support. Always read the labelled and follow directions for use.

What Is L-Phenylalanine?

L-Phenylalanine is an essential amino acid your body cannot produce on its own – you need to obtain it from your diet or through supplementation. As a free-form amino acid, it's readily absorbed and utilised by the body. It serves as a precursor to important molecules: first converted to tyrosine, then to L-dopa, a precursor to neurotransmitters like norepinephrine and dopamine. Additionally, it's a direct precursor to phenylethylamine (PEA), which influences mood and focus. This makes L-Phenylalanine a key nutrient for supporting healthy neurotransmitter function.*

Key Benefits of L-Phenylalanine

By supporting the production of norepinephrine and dopamine, L-Phenylalanine may help maintain mental alertness and a positive outlook.* Its role in PEA production can contribute to feelings of wellbeing. Since it's essential, adequate intake is important for overall health, particularly for those on vegetarian or vegan diets or with increased needs. Source Naturals provides 500 mg of free-form L-Phenylalanine per tablet, making it convenient to support these pathways.*

Who Should Take L-Phenylalanine?

Adults looking to support cognitive function and mood balance may benefit from L-Phenylalanine. Vegetarians and vegans might have lower amino acid intakes, making supplementation practical. Athletes and active individuals may use it to support recovery and focus. Always consult a healthcare professional before use, especially if you have phenylketonuria (PKU), high blood pressure, or are taking MAO inhibitors.

Frequently Asked Questions

What's the difference between L-Phenylalanine and DL-Phenylalanine? L-Phenylalanine is the natural form found in foods and used by the body. DL-Phenylalanine is a mixture of the L- and D-forms, sometimes used for different purposes. This product contains only the L-form.

How should I take L-Phenylalanine? Take 1 to 2 tablets daily, preferably on an empty stomach for better absorption. Do not exceed recommended dosage unless directed by a healthcare professional.

Can I take L-Phenylalanine with other supplements? Yes, but avoid combining with high-protein meals or other amino acid supplements without guidance, as absorption may compete. Always consult a health care provider.

Is this product safe for long-term use? L-Phenylalanine is generally safe when used as directed. However, individuals with certain medical conditions should seek medical advice before prolonged use.
