  • Reduces biorhythm hormone production.
  • Stress control.

Produced by the pinealocytes in pineal glands, Melatonin is a hormone responsible for the regulation of biorhythm. Biorhythm is disrupted by stress-related incidences, long distance travel that crosses multiple time zones, and changing work shifts. It performs the task of a biological clock within the body and also acts as an antioxidant. Melatonin signals regulate the circadian cycles by emitting chemical signals that decrease the body’s temperature and cause drowsiness. Melatonin also helps to reduce stress.

The level of melatonin decreases with age. Vitamin B6 contained in Melatonin Sustain also improves melanin metabolism and aids a healthy and stress-free lifestyle.

Suggested Use: Take 1 or 1/2 tablet 20–30 minutes prior to bedtime, or as directed by your qualified health care consultant.
