The 5-HT2A-rs6314 marker is a single nucleotide polymorphism (SNP) in the HTR2A gene, which encodes the 5-HT2A serotonin receptor. This receptor plays a key role in regulating mood, cognition, sleep, appetite, and how the brain responds to serotonin — one of the most important neurotransmitters for mental health and emotional balance.
The rs6314 SNP involves a C to T substitution at a specific point in the gene, leading to a change in the receptor’s structure and function. Because serotonin receptors influence both the central nervous system and peripheral systems (including gut function and cardiovascular health), variations in this gene may affect both mental and physical health outcomes.
Optimal range: 0 - 15 mg/24 hr
5-Hydroxyindolacetic acid (5-HIAA) is an important chemical compound in the medical and biochemical fields, acting as a primary interest for its role as a metabolite in the human body. Essentially, it's what remains after serotonin, a key neurotransmitter responsible for regulating mood, appetite, and sleep among other functions, is broken down. The body converts serotonin into 5-HIAA, which is then excreted in the urine.
Optimal range: 1.17 - 8.06 ug/mg creatinine
5-Hydroxyindoleacetic acid (5HIAA) is a breakdown product of serotonin that is excreted in the urine. Serotonin is a hormone found at high levels in many body tissues. Serotonin and 5HIAA are produced in excess amounts by carcinoid tumors, and levels of these substances may be measured in the urine to test for carcinoid tumors.
Optimal range: 3.8 - 12.1 mmol/mol creatinine

A metabolite produced by Aspergillus and possibly other fungal species in the GI tract.
Optimal range: 0 - 18 mmol/mol creatinine
A metabolite produced by Aspergillus and possibly other fungal species in the GI tract.
Optimal range: 0 - 28 mmol/mol creatinine
A metabolite produced by Aspergillus and possibly other fungal species in the GI tract. Prescription or natural antifungals, along with high-potency, multi-strain probiotics, may reduce overgrowth levels.
Optimal range: 0 - 13.4 mmol/mol
5-Hydroxymethyl-furoic Acid is a naturally occurring human urinary metabolite, a nematicide, a bacterial xenobiotic metabolite and a fungal metabolite. It is a metabolite produced by Aspergillus and possibly other fungal species in the GI tract. Consider a Gut zoomer or fungal antibodies test in order to determine the root cause. It was first identified in the urine of a leukemic patient who was excreting an abnormal amount of its glycine derivative. Multi-strain probiotics can be supplemented to improve the condition.

Folates function as cofactors in the transfer and utilization of one carbon groups. These reactions are essential for the production of purines and pyrimidines for DNA synthesis. Folates also play a major role in the regeneration of methionine from homocysteine. In pregnancy, poor body stores of folates may lead to neural tube defects, such as spina bifida.
