HPA Axis Dysfunction: Cortisol and Stress

Cortisol is a hormone produced by the adrenal glands in times of stress, and it also plays many roles in your normal bodily functions. It is a multi-purpose hormone that needs to be in the right amount (not too high, not too low) and at the right time. Your genes play a big role in how likely you are to have problems with cortisol.

Intelligence Genes

Hundreds of identified genes influence intelligence, from IQ scores to musical ability. Learn more about your intelligence strengths and ways to enhance your cognitive function.

Anxiety: Genetics and personalized solutions

When it comes to anxiety, genetic variants combine with environmental factors (nutrition, sleep, relationships, etc) when it comes to anxiety. Understanding your anxiety genes can help you figure out which pathways to target.

Dyslexia: Genetic Connections

While dyslexia is known to run in families, the role of genetics in dyslexia is still being determined. Here is a quick look at some of the genes involved in dyslexia, affecting around 10% of the population.

Tryptophan Pathways: Kynurenine, Serotonin, and Melatonin

Tryptophan is an amino acid that the body uses to make serotonin and melatonin. Genetic variants can impact the amount of tryptophan that is used for serotonin. This can influence mood, sleep, neurotransmitters, and immune response.

GABA: Genetics, Anxiety, and Immune Response

GABA (gamma-Aminobuyteric acid) is a neurotransmitter that acts to block or inhibit a neuron from firing. It is an essential way that the brain regulates impulses, and low GABA levels are linked with several conditions, including anxiety and PTSD.

Lithium Orotate, Vitamin B12, and Mood

For some people, low-dose, supplemental lithium orotate is a game changer when combined with vitamin B12. But other people may have little to no response. The difference may be in your genes.

Psychopaths: Born not made?

Can you be born a psychopath? Are there genes linked to psychopathy? Discover how your genes don’t predestine you to become a psychopath.

Depression genes

Depression, genetics, and mitochondrial function

How does mitochondrial dysfunction relate to major depressive disorder? Learn about the causes of mitochondrial dysfunction as well as genetic variants that link the risk of depression to the mitochondria.

MTHFR and Depression

We are all genetically unique, and a common genetic variant in the MTHFR gene causes some people to be more susceptible to having low folate levels. This article explains the research linking MTHFR variants, folate, and depression — and gives you information on how diet or supplements may help.

COMT: Interactions with Supplements

Some supplements interact with COMT variants to impact the rate at which neurotransmitters are broken down. Check your COMT genotype and discover how this may affect your reaction to different supplements or combinations of supplements.

ANK3: Bipolar Disorder and Brain Development

The genetic variants in the ANK3 gene impact the risk of psychiatric disorders that include bipolar disorder and autism spectrum disorders, and heart arrhythmia. Discover how ANK3 impacts neuronal formation and transmission and how this ties into an increased risk of psychiatric disorders.

Why Circadian Rhythm Disruption Causes Depression

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. ​

Genetics and 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.
