An Important Piece of the COVID-19 Puzzle? - Melatonin

Publicado por Ben White en

By Margaret N.Groves, M.Phil. ZRT Laboratory The Italian magazine Evolutamente recently published a well-researched article exploring the link between melatonin and COVID-19, pneumonia and inflammation. It’s a compelling article so let’s take a look at the key argument and see why melatonin could be so important. Melatonin and Health Melatonin is a hormone produced by the pineal gland during the hours of darkness to usher the initiation of sleep, and peaks at around 2 a.m. Its production is reduced when we are exposed to light during the night, such as when watching TV or looking at other electronic screens late at night....

By Dr. Allison Smith, ZRT Laboratory I would like to thank everyone who joined in our webinar on the Role of Hormones in Sleep Disturbances!  There were a number of questions I wasn’t able to address due to time constraints but they were all excellent questions. I thought at least someone would be interested in a follow-up as I speak to the rest of the questions just as a little wrap-up. Q: Wouldn't it be nice to include Dried Urine Melatonin in your ZRT Comprehensive Profile, to be able to evaluate Morning Cortisol when low? Maybe it is low while Melatonin...

Like most clinicians, I tended to think of it for sleep problems in general and as an adjunct treatment for some of the comorbidities associated with different cancers. I was also vaguely aware that there was a physical reason my colitis patients usually presented with depression and...

The Role of Melatonin in Sleep

Publicado por Ben White en

Melatonin is a ubiquitous little hormone that comes in an indolamine package similar to serotonin, its precursor. Thanks to its unique structure, it can travel easily through the blood stream and readily crosses the blood-brain and placental barriers. It is synthesized and used all over the body to perform a number of indispensable roles. It’s the main reason our bodies know what time it is and what it’s supposed to be doing at any given moment. It signals the transcription of genes that regulate the cell cycle, neutralize free radicals, and decrease inflammation. Its claim to fame, however, is its role in promoting sleep. Melatonin's Daily...
