What is CAP?

Scientific Name: Bovine a-casein hydrolyzed decapeptide, Casozepine

CAP is produced and refined as a protein containing multiple sets of Casozepine, through the fermentation process using endotoxin-free E. coli or edible medical grade yeast. CAP is embedded in a special carrier to form a natural barrier that is not easily destroyed by gastric acid and pepsin. The use of ultrafiltration membrane purification, the development of peptide orientation fermentation technology, the production of high milk peptides, and the high concentration and purity of amygdalin CAP, allows the capsule to remain intact in the intestine allowing it to fully absorb into the system.

CAP- Can inhibit the secretion of hormones in the hypothalamus of the brain (this links the nervous system to the endocrine system via the pituitary gland). In doing this it helps reduce the adrenal secretion of large amounts of cortisone that is recognized as being a contributing factor in sleep disorders. By reducing the amount of cortisone it helps to restore the body to a state of calm and relaxation. CAP also has potential as a treatment for anti-stress, increasing the brains memory and helping insomnia patients to sleep.

We are sure that CAP is a protein fragment that mimics bovine a-casein hydrolyzed decapeptide, (10 peptides). The source is from bioengineered fermentation(using endotoxin-free E. coli or edible pharmaceutical grade

yeast)and does not contain any animal ingredients.

Ingredient Information

Safe for vegetarians



Take 1 capsule 1 hour before sleep


It usually takes 5 to 7 days to improve sleep quality.

For sufferers of serious insomnia syndrome and sufferers who are already taking sleeping medication it may take up to 4 weeks (the manufacturer recommends taking double the daily dose in this instance).

Anyone already taking a sleeping medication, the manufacturer recommends to take the SleepPeptide in addition to the current medication and slowly reduce the consumption of sleeping medication, depending on dependency.

It is always recommended to consult your health advisor.
