Personalized Nutrition in Clinical Practice: Leveraging iollo's Metabolomic Testing for Optimal Patient Outcomes

March 14, 2024


Personalized nutrition and supplement guidance are essential aspects of optimizing overall health and well-being. iollo's advanced metabolomic testing offers healthcare providers a powerful tool to identify nutrient imbalances and develop personalized dietary and supplement recommendations for their patients. This educational material aims to familiarize physicians with the key nutrition and supplement markers measured by iollo's test, their interpretation, and the potential benefits for patients seeking to optimize their health through personalized nutrition.

Who May Benefit from This Test?

iollo's nutrition and supplement testing can be particularly beneficial for patients looking to improve various aspects of their health and well-being. Some of the key indications for testing include:

  • Energy levels and vitality: Patients seeking to optimize their energy levels and overall vitality may benefit from identifying nutrient imbalances or deficiencies that can impact energy production and metabolism.
  • Cognitive function and mental clarity: Individuals looking to enhance their cognitive performance and mental clarity can gain insights into their nutritional status and potential areas for improvement through metabolomic testing.
  • Digestive health and nutrient absorption: Patients with digestive issues or concerns about nutrient absorption may benefit from assessing their metabolomic profile to identify specific nutrient imbalances and guide targeted interventions.
  • Metabolic disorders (e.g., diabetes, insulin resistance): Individuals with metabolic disorders, such as diabetes or insulin resistance, can use metabolomic testing to optimize their nutrition and supplement regimen and support healthy glucose and insulin metabolism.
  • Overall health and well-being: Patients seeking to optimize their overall health and well-being can benefit from a comprehensive assessment of their nutritional status and personalized recommendations based on their unique metabolomic profile.

Other patients who may benefit from nutrition and supplement testing include those with chronic health conditions, individuals following specific dietary patterns (e.g., vegetarian, vegan, or ketogenic diets), and athletes or active individuals looking to optimize their performance and recovery.

Understanding Nutrition and Supplement Markers

iollo's Nutrition and Supplement Panel measures a comprehensive set of biomarkers that provide insights into various aspects of nutritional status and metabolic function. Some of the key markers include:

  1. Amino Acids (e.g., Isoleucine, Leucine, and Methionine)
  • Amino acids are the building blocks of proteins and play crucial roles in various metabolic processes, including energy production, neurotransmitter synthesis, and immune function.
  • Imbalances in specific amino acids, such as elevated branched-chain amino acids (isoleucine and leucine) or high methionine levels, may indicate underlying metabolic dysfunction or increased risk for certain health conditions [1,2].
  1. Fatty Acids (e.g., Docosahexaenoic Acid and Arachidonic Acid)
  • Fatty acids are essential components of cell membranes and play important roles in brain health, inflammation, and cell signaling.
  • Low levels of docosahexaenoic acid (DHA), an omega-3 fatty acid, have been associated with various health issues, such as cognitive decline and cardiovascular disease [3], while high levels of arachidonic acid (AA), an omega-6 fatty acid, have been linked to increased inflammation [4].
  1. Choline-to-Betaine Ratio
  • Choline and betaine are essential nutrients involved in methylation pathways, which regulate gene expression, neurotransmitter synthesis, and detoxification processes [5].
  • An imbalanced choline-to-betaine ratio may indicate impaired methylation capacity and has been associated with various health conditions, such as cardiovascular disease [6].
  1. Trigonelline
  • Trigonelline is a bioactive compound found in coffee and has been associated with various health benefits, including improved glucose metabolism and neuroprotection [7].
  • Higher levels of trigonelline may indicate regular coffee consumption and potential beneficial effects on metabolic health and cognitive function [8].

Interpreting Results and Patient Benefits

iollo's metabolomic testing provides valuable insights into patients' nutritional status and metabolic function:

  • Identifying nutrient imbalances or deficiencies can reveal underlying issues that may impact various aspects of health, such as energy levels, cognitive function, digestive health, and overall well-being.
  • Patients seeking to optimize their nutrition and supplement regimen can particularly benefit from the comprehensive analysis of their metabolomic profile, as it allows for the development of personalized recommendations tailored to their unique needs and health goals.

iollo's test results are highly actionable, offering personalized recommendations based on each patient's unique health history and context:

  • For example, patients with low levels of DHA may benefit from increasing their intake of fatty fish, such as salmon or sardines, or considering a high-quality omega-3 supplement [9].
  • Those with elevated branched-chain amino acids may be advised to reduce their intake of high-protein foods, particularly from animal sources, and increase their consumption of fiber-rich plant foods to support healthy insulin sensitivity [10].

Physicians can assist patients in prioritizing 2-3 key recommendations to focus on initially, based on the most significant nutrient imbalances and the patient's individual goals and preferences. Regular monitoring of these biomarkers can also help track patients' progress and optimize their nutrition and supplement plan over time.


iollo's advanced metabolomic testing provides healthcare providers with a powerful tool to assess and optimize their patients' nutritional status and metabolic health. By understanding the key markers measured and their implications for nutrient balance and metabolic function, physicians can develop personalized nutrition and supplement recommendations that support their patients' unique health needs and goals. Integrating Iollo's testing into clinical practice can complement other functional and integrative approaches to personalized nutrition, ultimately helping patients achieve optimal health outcomes.
