Who Should Consider DL-Phenylalanine?

Are you an adult seeking to support mental focus and physical comfort? DL-Phenylalanine (DLPA) from Source Naturals is a unique combination of two forms of the amino acid phenylalanine, designed as a food supplement for those with active lifestyles. It may be particularly useful for individuals transitioning off pain medications under professional guidance, whilst it is not a replacement for prescribed treatments. Pregnant or nursing women, and those with conditions such as PKU or high blood pressure, should consult a health care professional before use.

Potential Benefits of DLPA Supplement

When taken as part of a balanced diet and healthy lifestyle, DL-Phenylalanine may offer several benefits:

  • May Support Mental Focus* – By providing building blocks for dopamine and norepinephrine, DLPA can help maintain alertness and concentration throughout the day.
  • Promotes Comfort and Wellbeing* – The D-form may influence endorphin breakdown, helping the body manage everyday discomfort.
  • Mood Balance* – Healthy neurotransmitter levels are linked to a positive outlook, and DLPA supplies the necessary amino acids.
  • Natural and Non-Habit Forming – As an amino acid supplement, it offers a natural option without harsh chemicals.

Individual results vary, and consistency is key for best results.

How to Use Source Naturals DLPA

The recommended dosage is 1 tablet 1 to 3 times daily, preferably on an empty stomach. Tablets can be swallowed whole or halved for easier administration. For optimal benefits, use regularly as part of your daily routine. Do not exceed the stated dose unless advised by a health care professional.

What Is DL-Phenylalanine?

DL-Phenylalanine (DLPA) is a blend of the D- and L- forms of the essential amino acid phenylalanine. L-Phenylalanine converts naturally into neurotransmitters like dopamine and norepinephrine, which help support alertness and focus. D-Phenylalanine works differently by potentially inhibiting enzymes that break down endorphins, the body’s natural comfort-promoting compounds. Together, they provide synergistic support for both mental and physical wellbeing.

Each Source Naturals DLPA tablet provides 750 mg of DL-Phenylalanine in a convenient form.

FAQs About DL-Phenylalanine

Is DLPA safe for long-term use?

DL-Phenylalanine is generally well-tolerated when used as directed. However, discuss long-term use with a health care professional, especially if you have pre-existing conditions or are taking medication.

Can DLPA cause side effects?

Some people may experience mild digestive upset or headache when starting. To minimise this, begin with a lower dose and increase gradually. Discontinue use and consult a doctor if adverse reactions occur.

Can I take DLPA with other supplements?

Yes, DLPA can be combined with other amino acids or multivitamins. Avoid taking it with high-protein meals as it may reduce absorption. Always check with a health care provider for personalised advice.
