THERAPY RECOMMENDATION

Positive Effects:

  • L-Phenylalanine is an essential amino acid. It is a precursor to L-tyrosine, the starting substance for the biosynthesis of the catecholamines dopamine, norepinephrine, and epinephrine.
  • It is also a precursor to L-tyrosine, the starting substance for the biosynthesis of insulin, melanin, L-thyroxine (T4), and L-triiodothyronine (T3).
  • L-Phenylalanine is the precursor to phenylethylamine (PEA), which has antidepressant, activity-enhancing, and attention-focusing effects.

Therapy Recommendations:There is evidence that the properties of the substances contained in the product may have a positive effect on health disorders of the mentioned indications:

  • acute and chronic stress management, anxiety, restlessness
  • to enhance physical and mental performance
  • promotes attention, focus, concentration
  • for depression and chronic fatigue syndrome (CFS)
  • in pain therapy, analgesic, for arthritis, osteoarthritis, migraine, etc.
  • support for weight management, appetite suppressant
  • for “chemo-brain” (possibly in combination with curcumin)


Contraindications:Do not use in children under 6 years of age. In cases of impaired kidney, liver, or heart function, and in cases of albumin deficiency, an adjustment of the individual dose is recommended. Patients taking beta-blockers have an increased risk of decompensated cardiovascular reaction, as beta-blockers inhibit the effect of adrenaline (emergency medical treatment). Patients with a tendency to allergic reactions and/or diseases based on histamine release (e.g., asthma) should be questioned about known allergens in accordance with the principles of therapeutic due diligence.

Contraindications:Phenylketonuria (PKU), hyperthyroidism. In the therapy of MAO inhibitors, dangerous hypertensive crises may occur.

CAUTION:Pre-infusion with the co-factors for clean catecholamine synthesis is
recommended: Folimetin, Vitamin B Complex Inject, Magnesium, Vitamin C. Additionally, please adjust iron, copper, and Vitamin B12 blood levels.

Note for Doctors and Therapists:In principle, for individual prescriptions, the doctor/therapist determines the indication. The suggestion is merely a recommendation for a therapy option, with the dosage and frequency of application being solely at the discretion of the doctor/therapist. The treating therapist is responsible for the treatment and must individually review and assess each application for each patient before starting treatment.

References

The literature references have been researched by us with the greatest possible care. Nevertheless, we assume no liability for the completeness and up-to-dateness of the study information. Many of the therapy options mentioned in the product information are based on findings obtained from animal or human cell cultures, animal experiments, observational studies, and, to a lesser extent, randomized controlled trials (RCTs).
The study situation regarding complementary medicines is subject to continuous development, which can sometimes lead to different results. We therefore recommend that therapists always carefully review the current study situation before using such preparations.
