Background: A novel milk peptide has been shown in laboratory setting to have natural anti-cancer properties and extend lifespan and improve metabolism in animal models. The purpose of this study was 1.) to determine the safety dosage range and, 2.) to determine whether this novel milk peptide positively influence blood markers, metabolism and improve quality of life.

Primary Outcome Measures:
  • Blood and Hormones [ Time Frame: 6 weeks ]
    General whole blood and serum clinical chemistries (cholesterol, triglycerides, glucose, blood urea nitrogen, creatinine, uric acid, muscle and liver enzymes) and hormones (insulin, homeostasis model of insulin sensitivity, and leptin).

Secondary Outcome Measures:
  • Psychosocial [ Time Frame: 6 weeks ]
    quality of life indices

  • Body Composition [ Time Frame: 6 weeks ]
    All participants were tested for changes in energy intake and body composition

Enrollment: 73

Study Completion Date: February 2007
Primary Completion Date: January 2007 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Milk Peptides Dietary Supplement: Hydrolyzed milk protein mixture
Take twice a day, dosage 6 ml-21 ml based on weight, mix with 1/2 cup of milk.
Other Name: AX-4
Placebo Comparator: Placebo
Participants ingested 6ml - 21ml (based on participants' weight) of clear, sugar-less liquid placebo mixed with 1/2 cup milk twice daily (once immediately after breakfast and once immediately after dinner). The supplements were prepared in liquid form and packaged in generic bottles for double blind administration. The placebo was a glycerol-based placebo matched for color, texture, and taste to the active supplement.
Dietary Supplement: Glycerol placebo

Participants ingested 6ml-21ml of placebo mixed with 1/2 cup milk twice daily. The supplements were prepared in liquid form and packaged in generic bottles for double blind administration. The placebo was a starch-based placebo matched for color, texture, and taste to the active supplement.

A food diary is maintained daily.

Detailed Description:
The study was conducted as a randomized, double-blind, placebo-controlled clinical trial in a university research setting. Healthy volunteers were randomly assigned to ingest in a double-blind and randomized manner either a placebo or milk peptides. Outcome measures were assessed at 0, 3, and 6 weeks of supplementation.
