ADVANCED FORMULA AND BENEFITS
L-Tryptophan
Tryptophan is an essential amino acid that produces a moodenhancing neurotransmitter called serotonin. When the body is
deficient in tryptophan, it also lacks serotonin. This can inhibit sleep
and trigger numerous physical and/or mental disorders. Tryptophan
deficiencies are associated with depression, insomnia, premenstrual
syndrome, schizophrenia, attention deficit disorders and autismspectrum disorders. Adequate levels of tryptophan are essential for
biochemical balance of the brain. PERQUE Sleep Guard uses only
the highest-quality, pharmaceutical-grade L- tryptophan, plus key
transport enhancer nutrients, for the most effective results.*
L-Tryptophan to Manage:
• Attention deficit disorder / hyperactivity disorder (ADD / ADHD)*
• Autism Spectrum Disorder (ASD)*
• Mild to moderate depression*L-Tryptophan vs. 5-HTP
PERQUE Sleep Guard uses L-tryptophan − and synergistic
ingredients − in their most beneficial, safe and natural forms.
By contrast, many sleep supplements use 5-HTP, a downstream
metabolite of tryptophan. While both 5 HTP and tryptophan
cross the blood brain barrier and convert to serotonin and
melatonin, tryptophan is safer, healthier and has a sustained
effect. The body can also transform tryptophan into other
helpful compounds within the body, like niacin which is
helpful in maintaining healthy sleep cycles.*
Additional 100% All-Active Ingredient Features
PERQUE uses nutrients only in their most bioavailable, natural
and beneficial forms. PERQUE Sleep Guard delivers the
active forms of vitamins B2 (riboflavin 5’-phosphate) and B6
(pyridoxal 5’-phosphate) − essential cofactors that maximize
the absorption and benefits of L-tryptophan and strengthen
its sleep- and mood-enhancing properties. In cases of mildto-moderate depression, we recommend combining PERQUE
Sleep Guard with PERQUE Mood Guard™, for maximum
mood-enhancing benefit.*
Note: Stay well-hydrated and avoid eating protein two hours before bedtime so the stomach can absorb and metabolize the L-tryptophan in
PERQUE Sleep Guard most efficiently.
