Indican is an indole produced when bacteria in the intestine act on the amino acid, tryptophan. Most indoles are excreted in the feces. The remainder is absorbed, metabolized by the liver, and excreted as indicanin the urine.

The remainder is absorbed, metabolized by the liver, and excreted as indicanin the urine.

Accumulated levels of Indican in the urine may suggest gastrointestinal dysbiosis or malabsorption.

Indican is a byproduct of tryptophan putrefaction by microbes in the gut. Accumulated levels of indican in the urine suggest higher levels of tryptophan putrefaction from gastrointestinal dysbiosis or malabsorption.

Production of indican occurs when tryptophan creates indoles in the colon. No other endogenous indoles are metabolized in this way, so when we see indican in the urine, it is directly related to gut production and a direct reflection of gut health. When there is concern of dysbiosis, there may be poor metabolism of sex hormones (including estrogen) along with chronic low-grade inflammation that can impact cortisol production and metabolism.

Indole is a byproduct of the microbial degradation of tryptophan that can be utilized in a variety of ways in the gut microbiome. Indole can bind to serotonin receptors in order to regulate behavior, gut motility, and food intake, and it can support immune and intestinal health by interacting with gut microbes, scavenging free radicals, and increasing the expression of xenobiotic-metabolizing enzymes like cytochrome P450. Indole also functions as a signaling molecule that may be increased during latent infections. Indole production must be balanced, as too much indole may produce unwanted changes in mood or cognition, yet insufficient indole production may damage the gut barrier.

Indoleacetic acid (IAA), or indole-3-acetate, is produced by the bacterial fermentation of the amino acid tryptophan.

IAA can be formed from several common gut microbes such as Clostridia species, Escherichia coli, and Saccharomyces species.

- A product of tryptophan fermentation. If elevated, decrease protein intake and address digestion and GI issues. Bacteroides, Clostridia, and E. coli ferment tryptophan to produced indoleacetic acid.

- It has been found elevated in liver disease, ASD, and cancer, and has been noted as a marker of microbial activity.

- Indoleacetic acid can be degraded by Bacillus subtilis, or Pseudomonas aeruginosa.

- Indoleacetic acid has been found in many foods, such as lettuce, cherry tomato, Chinese bayberry, and okra.

The Inflammation-Associated Dysbiosis (IAD) score serves as a crucial metric for evaluating the interplay between gut inflammation and microbiota composition. This score holds significance as it illuminates how inflammation within the gastrointestinal tract impacts the delicate balance between beneficial and harmful gut bacteria.

Derived from a pattern-based algorithm, the Inflammation-Associated Dysbiosis score categorizes patients based on their scores, revealing a negative correlation between mean IAD score and commensal bacteria abundance, alongside positive associations with fecal calprotectin, EPX, and sIgA levels. Validation studies, encompassing Genova’s database of IBD patients and an independent UCLA study with IBD cohorts, underscore its reliability.

The causal relationship between inflammation-associated dysbiosis and inflammation remains uncertain. A low IAD score coupled with elevated inflammatory markers suggests that the gut microbiome might not be a contributing factor to the inflammatory condition, warranting exploration of alternative etiologies. Longitudinal investigations are imperative to unravel the implications of a high IAD score in the absence of elevated inflammatory markers. It's plausible that an inflammatory microbiome pattern may precede the onset of elevated inflammatory markers, underscoring the need for further research.

Influenza Type A antibody serum refers to the specific antibodies present in the blood serum that are directed against Influenza virus Type A, a highly variable virus responsible for seasonal flu epidemics and occasional pandemics. These antibodies are part of the body's adaptive immune response, produced by B cells as a defense mechanism following exposure to the virus or vaccination. The presence and concentration of these antibodies can be quantified through serological assays, such as hemagglutination inhibition (HI) assays, neutralization tests, and enzyme-linked immunosorbent assays (ELISA). The detection and quantification of Influenza Type A antibodies are crucial for several purposes: epidemiological surveillance, to assess the spread and impact of the virus in populations; vaccine efficacy studies, to evaluate the immune response elicited by flu vaccines; and individual diagnosis, to understand a person's immune status or history of exposure to the virus.

The marker "Influenza Type B Antibody Serum" refers to the presence of specific antibodies in the serum that are produced in response to infection with Influenza Type B virus or following vaccination against this virus. These antibodies are a crucial component of the immune response and serve as indicators of an individual's exposure to the virus or their immunization status. Influenza Type B is one of the three main types of influenza viruses (alongside Types A and C) that infect humans and can cause seasonal epidemics of disease. The presence of these antibodies is detected through serological assays, which are laboratory tests that measure the concentration of antibodies in the blood serum.

Function: An essential nutrient, inositol is found in cell membranes and is needed for proper function of hormones. Inositol, similar to choline, is a component of phospholipids (phosphatidyl inositols). Phosphatidyl inositols function as cell membrane components and as regulators of cell membrane transport by acting as a calcium-mobilizing system (the “PI effect”). Thus, inositol status interacts with a wide variety of hormonal and regulatory events in cells. Lipotropic activity (reduction of blood or tissue lipid levels) of inositol centers around the role of phosphatidyl inositol in lipoproteins. Since inositol is widely available from dietary sources, endogenous synthesis and gut microfloral synthesis, inositol is not classified as a vitamin. Nevertheless, inositol has been considered as a component of the B vitamin complex.

The presence of antibodies to Instant Coffee is an indication of food immune reactivity. The offending food and its known cross-reactive foods should be eliminated from the diet. Adverse reactions to Coffee plant, inhaled grounds and consumed food products have been reported.

Insulin is a vital hormone produced by the pancreas, an organ located behind the stomach that plays a key role in both digestion and blood sugar regulation. Acting like a key, insulin allows the body’s cells to absorb glucose from the bloodstream for energy while also signaling the liver, muscles, and fat tissue to store excess glucose for later use. When insulin is insufficient or the body becomes resistant to it—a condition known as insulin resistance—glucose accumulates in the blood, increasing the risk of serious health complications. Diabetes is a chronic condition that results when the body either doesn’t produce enough insulin, as in type 1 diabetes (often due to autoimmune destruction of insulin-producing beta cells), or cannot use insulin effectively, as in type 2 diabetes, which is commonly linked to lifestyle factors, genetics, and age. A temporary form, gestational diabetes, can also occur during pregnancy due to hormonal changes that cause insulin resistance. Insulin resistance itself may develop silently and is influenced by factors such as excess abdominal fat, physical inactivity, poor diet, certain medications, and genetic predisposition. If left unmanaged, it can progress to prediabetes and eventually to type 2 diabetes. Early detection is critical and is often done using the Hemoglobin A1C test, which measures average blood glucose levels over the past three months and helps define normal, prediabetic, and diabetic ranges. Supporting healthy insulin function is essential not only for energy metabolism but also for reducing the risk of related conditions like non-alcoholic fatty liver disease and cardiovascular disease, underscoring the importance of proactive blood sugar management for long-term health.
