Norival

Norival

Norival is a specialized tyrosine product used to help low moods when tyrosine hasn't worked effectively enough.*

Norival combines biopterin with N-acetyl-L-tyrosine, a highly bioavailable form of L-tyrosine for the natural precursor treatment of low moods N-acetyl-L-tyrosine can be used in lower doses than L-tyrosine.*

The amino acid L-tyrosine converts to L-dopa & norepinephrine in the brain to correct depression. The conversion is catalyzed by the enzyme tyrosine hydroxylase. Other enzymes phenylalanine hydroxylase & tryptophan hydroxylase also play important roles in the synthesis of neurotransmitters which modulate and control mood.*

These enzymes only work in the presence of a co-factor called biopterin. Sometimes low biopterin levels are the weak link in the sequential chain of reactions leading to the creation of these essential brain chemicals.*

Researchers have found decreased biopterin in the postmortem brains of those with depression, & an increased excretion of biopterins in those with severe depression. Concentration of biopoterin in the postmortem brains of those with Alzheimer's was significantly reduced when compared with controls.*

For more details on the natural precursor treatment of depression, see Dr. Slagle's book "The Way Up From Down."
