PERQUE Sleep Guard

Supports restorative sleep with health restoring sleep rhythms, and better brain activity, mood and energy.

PERQUE Sleep Guard enhances restful, healing sleep by restoring healthy brain chemistry. Regain sleep that refreshes, revitalizes and reenergizes mind and body. With PERQUE Sleep Guard you naturally rebuild resilience. A safer, natural alternative to habit-forming pharmaceuticals, PERQUE Sleep Guard boosts the body’s own production of serotonin, the brain chemical that says “Ah… we can handle this.” When the sleep center operates properly, renewing rest occurs. Start PERQUE Sleep Guard for improved quality of sleep and quality of life.* Benefits of PERQUE Sleep Guard All-Active Formulation:

  • Restorative sleep*
  • Healthier REM deep sleep rhythms*
  • Mood and energy stability*
  • Neurohormonal balance*
  • Premenstrual and perimenopausal hormone balance*

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.* 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 autism spectrum 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.*

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
