Glycine and Slow Wave Sleep
Sleep quality is essential for good health and our genetics play a role in how much slow wave sleep we naturally get.
Sleep & Circadian Rhythm
Your circadian rhythm is the 24-hour internal clock which drives many important aspects of your health, and sleeping well is part of this. Learn about how your genes impact your circadian rhythm and how this interacts with other health topics.
Member’s: Check out the Sleep and Circadian Rhythm Topic Summary Report for a quick overview of all your genetic variants.
DEC2 Gene: Short Sleep Mutation
Are you naturally a short sleeper? Mutations in the DEC2 gene decrease the need for sleep.
Sleep Report: Genetic Causes of Sleep Problems
This is a quick (Member’s Only) overview of how your genetic variants impact various aspects of sleep including insomnia, circadian rhythm, and sleep quality.
Genomics and Teeth Grinding (Bruxism)
Grinding your teeth at night can be due, in part, to genetic variants in the serotonin genes.
Supplemental Melatonin: Immune system superstar
Melatonin is important for setting your circadian rhythm and for immune health. Dig into the details on melatonin supplements, scientific research, and more.
Restless Leg and Periodic Limb Movement Disorder: Genes and Solutions
Many know the frustration of disrupted sleep due to RLS and periodic limb movement disorder (PLMD). Genes play a role in your risk for these disorders, and there are specific research-based treatments to explore.
Depression, Genetics, and Circadian Rhythm
For some people, circadian disruption can be chronic – and at the heart of depression or mood disorders. Genetic variants play a role in this susceptibility. Fortunately, there are solutions that may help.
Lithium Orotate: Mood, Alzheimer’s, and Aging
Researchers found that Texas counties with higher levels of lithium in their groundwater had less of an increase in Alzheimer’s rates compared with counties that had lower levels of lithium. This isn’t a total surprise since previous studies had linked lithium to a decreased risk of dementia, but it is a great confirmation at a large scale population level.
Problems sleeping? Your genes could hold the solutions
An overview explaining how your genes impact sleep, including insomnia, restless leg, narcolepsy, and circadian rhythm genes. Start here and then dive deeper into the specific topics.
Circadian Rhythm and Your Immune Response to Viruses
Your circadian rhythm influences your immune response. Learn how this rhythm controls white blood cell production and why melatonin is important in protecting against viral and bacterial infections.

Increased Slow Wave Sleep
Find out how genes interact with your lifestyle in controlling the amount of deep sleep you get each night. Check out your genetic variants and hack your sleep. (Member’s article)
Genetics of Seasonal Affective Disorder
Seasonal Affective Disorder (SAD) is characterized by recurrent depression with a change in the season usually in fall/winter for most. Scientists think this is possibly due to an aberrant response to light – either not enough brightness to the sunlight or not enough hours of light. Your genes play a big role in this responsiveness to light.
Bipolar Disorder, Depression, and Circadian Clock Genes
New research shows that depression and bipolar disorder are linked to changes or disruption in circadian genes. Some people carry genetic variants in the circadian genes that make them more susceptible to circadian disruption.
BMAL1’s impact on the “Big 3”: heart disease, cancer, and diabetes
A core circadian rhythm gene, BMAL1, influences heart disease risk, diabetes, and cancer. Check your genes and learn how to mitigate the risk.
How natural supplements can change circadian gene expression
Did you know that some supplements change the expression of your core circadian clock genes? Your core circadian rhythm genes are foundational to your health, and some supplements alter that rhythm.
Melatonin: Key to Health and Longevity
More than just a sleep hormone, melatonin is at the heart of many health topics. Your genetic variants play a big role in the production of melatonin. Learn how your lifestyle and diet interact with your melatonin-related genes.
Blue-blocking Glasses: Why? Which ones?
An easy way to improve sleep and increase melatonin production at night is to wear blue light blocking glasses before bed. Explore the research on why this is so important, and learn about the different options available for blue-blocking glasses.
Do you wake up at 4 am? Genetics and early waking insomnia
Seeing 3:30 or 4:00 on your clock each morning? There could be a physiological reason for this. Learn about the genetic variants linked to early waking insomnia and the connection to depression. (Member’s article)
