Melatonin

Melatonin is used for numerous conditions but is showing the most promise in short-term regulation of sleep patterns, including jet lag.

Insomnia: Melatonin helps to induce sleep in people with- 

• Disrupted circadian rhythms (such as those suffering from jet lag or poor vision or those who work the night shift)
• Low melatonin levels (such as some elderly and individuals with schizophrenia)
• Children with learning disabilities who suffer from insomnia.

Osteoporosis: Melatonin stimulates cells called osteoblasts that promote bone growth.

In Menopause: Melatonin helps peri- or postmenopausal women to regulate sleep patterns.

Eating disorders: Melatonin levels may play a role in the symptoms of anorexia.

Sarcoidosis: Sarcoidosis is an inflammatory disease that affects multiple organs in the body, but mostly the lungs and lymph glands. 

Attention Deficit Hyperactivity Disorder (ADHD): It may be effective in managing sleep disturbances in children with this condition
