DL-Phenylalanine Plus Powder 100 grams

  • L-phenylalanine is an essential amino acid which can be converted to L-tyrosine by a complex biochemical process which takes place in the liver.
  • L-tyrosine can be converted by neurons in the brain to dopamine and norepinephrine (noradrenaline), hormones which are depleted by stress, overwork and certain drugs.
  • By replenishing norepinephrine in the brain, mental energy levels are enhanced and a feeling of contentment often occurs.
  • The conversion step from L-tyrosine to norepinephrine may be enhanced if the cofactors (vitamins B6 and C) are included.
  • Care with blood pressure should be taken when supplementing L-phenylalanine or L-tyrosine.*

Caution

Cancer patients should avoid taking L-phenylalanine and Ltyrosine. Certain cancers, such as melanoma, depend on these amino acids to fuel their growth. Supplemental use of L-phenylalanine and L-tyrosine may raise or normalize blood pressure. Insomnia may occur from over-stimulation if taken too close to bedtime. Individuals with the rare metabolic disorder Phenylketonuria should avoid phenylalanine.
