Thank you for your support!

A GI-Advanced Profile, which includes tests for Zonulin and H. pylori, can help you better understand your digestive health. Zonulin is a protein that controls the tightness of your gut lining. Higher levels may point to issues like leaky gut, which can affect overall wellness. H. pylori, a common bacterium, is known for causing stomach ulcers and can lead to ongoing digestive discomfort if not addressed immediately. Ordering this test online offers a convenient, confidential way to monitor these key markers. You can order a GI Advanced Profile (with Zonulin and H. pylori) test online without a prescription.

Test Description

The GI-Advanced Profile examines the health of your gut microbiome, which is the group of microorganisms that live in your digestive system. These microorganisms are crucial for proper digestion, immune function, and overall health. When the balance of these microbes is disrupted, it can lead to various health issues, such as digestive problems, skin conditions, autoimmune diseases, and more.

The test includes multiple markers that offer a comprehensive look at your gut health. It also includes key markers like Zonulin and H. pylori, which provide important information about how your gut is functioning. Zonulin is a protein that controls how open or tight the gut lining is. If Zonulin levels are too high, it can signal “leaky gut,” where the gut lining becomes too porous. This allows harmful substances to leak into the bloodstream, causing inflammation and possibly leading to other health problems.

H. pylori is a type of bacteria found in the stomach. While it doesn’t cause problems for everyone, it can lead to stomach ulcers and long-term inflammation if left untreated. Testing for H. pylori can help identify the cause of digestive issues, like ulcers or gastritis.

By looking at these markers, the GI-Advanced Profile can help spot potential problems in your gut health. Knowing more about your gut function can help you take steps to restore balance, reduce inflammation, and improve digestion, supporting better health in the long run.

The test can reveal how these diets are affecting gut microbiome diversity, gut permeability, and overall digestive function.
  • Individuals with chronic stress or anxiety: People dealing with chronic stress or anxiety may want to assess their gut health, as stress has been shown to impact gut microbiome diversity and permeability. The GI-Advanced Profile can help identify markers like Zonulin and H. pylori that could be contributing to gut issues or mental health concerns.
  • People with unexplained weight gain or difficulty losing weight: Those struggling with unexplained weight gain or finding it difficult to lose weight despite efforts may benefit from this test. An imbalanced gut microbiome or high Zonulin levels can disrupt metabolism and contribute to weight-related issues, making this test useful for identifying potential causes.

This test can help assess the gut microbiome’s condition and detect any imbalances or infections that could worsen during treatment.
  • People with frequent or recurring fungal infections: Individuals who suffer from frequent fungal infections, such as yeast infections or systemic fungal infections, could benefit from the test. The GI-Advanced Profile can identify imbalances in the gut microbiome that may promote fungal overgrowth, including Candida species.
  • Individuals with persistent bloating or digestive discomfort after meals: People who experience bloating, discomfort, or fullness after eating may have underlying gut issues that the GI-Advanced Profile can help identify. This could include bacterial imbalances, H. pylori infection, or gut permeability problems that are contributing to these symptoms.
  • People with a sedentary lifestyle: Individuals with limited physical activity may experience gut health issues related to poor digestion and microbiome imbalances. Testing their gut with the GI-Advanced Profile could help identify potential disruptions and provide guidance for improving gut health through diet, exercise, and other interventions.
  • Individuals with a history of traveler’s diarrhea or travel-related gastrointestinal illnesses: Those who have experienced gastrointestinal illness while traveling, especially in areas with lower sanitation standards, may want to test their gut health. The GI-Advanced Profile can identify lingering pathogens like H. pylori or changes in gut microbiome composition that could affect overall health after an infection.
  • Individuals with chronic diarrhea or constipation: Those with long-standing issues related to either chronic diarrhea or constipation may find the GI-Advanced Profile useful in pinpointing the cause. Testing for gut microbiome imbalances, Zonulin levels, and H. pylori can reveal underlying issues affecting bowel movements and digestive regularity.
  • People with a history of inflammatory bowel disease (IBD) flare-ups: Individuals with Crohn’s disease, ulcerative colitis, or other forms of IBD may want to use the GI-Advanced Profile to monitor their gut health. This test can help detect flare-ups, identify bacterial imbalances, and assess Zonulin levels, which are often elevated in inflammatory conditions.
  • Individuals with chronic or recurrent skin infections: People who experience persistent skin infections or conditions like eczema, acne, or psoriasis may want to explore their gut health. Imbalances in the gut microbiome and increased Zonulin levels have been linked to skin health, and this test can help identify underlying issues.
  • People with neurological conditions: Individuals with neurological conditions like migraines, autism spectrum disorders, or multiple sclerosis (MS) may consider testing their gut health. Research has shown that the gut-brain connection is strong, and disruptions in the microbiome or gut permeability can influence these conditions.
  • Individuals with hormonal imbalances: People experiencing unexplained hormonal imbalances, such as irregular menstrual cycles, thyroid issues, or unexplained weight gain, may benefit from testing their gut health. A compromised gut microbiome and elevated Zonulin levels can interfere with hormone regulation and metabolism.
  • Vegetarians or vegans with digestive issues: Those following vegetarian or vegan diets may face challenges related to nutrient absorption or digestive discomfort, especially if they are not getting enough fiber or other essential nutrients. The GI-Advanced Profile can assess gut health, identify nutrient malabsorption, and provide insights into potential gut imbalances.
  • People who consume a high-fat diet: A diet high in fats can alter the gut microbiome and contribute to gut permeability. Individuals on a high-fat diet who are experiencing digestive discomfort, inflammation, or other health concerns may benefit from testing for Zonulin levels and overall gut health.
  • Individuals with a history of gastrointestinal cancer: Those who have had gastrointestinal cancers such as colon, stomach, or esophageal cancer may want to track their gut health post-treatment. The GI-Advanced Profile can help monitor gut microbiome recovery and identify any imbalances that may contribute to long-term digestive issues.
  • People dealing with chronic sinus infections: Chronic sinus infections or rhinosinusitis may be linked to gut health, as an imbalance in the gut microbiome can affect the immune system. Testing the gut could provide insights into potential sources of chronic inflammation that might be contributing to persistent sinus issues.
  • Individuals with a history of liver or gallbladder disease: People with liver or gallbladder conditions, such as fatty liver disease, cirrhosis, or gallstones, may benefit from this test to evaluate how their gut health is influencing liver function. The microbiome plays a role in liver health, and Zonulin levels can indicate whether there is an issue with gut permeability that could impact overall liver function.
  • People with chronic or unexplained joint pain: Chronic joint pain, particularly in the absence of an obvious injury or diagnosis, may be linked to gut health. A compromised gut microbiome and high Zonulin levels are associated with systemic inflammation, which can contribute to joint pain and discomfort.
  • Athletes with digestive issues or performance concerns: Athletes who experience digestive discomfort, fatigue, or immune system stress may find the GI-Advanced Profile helpful. Gut health directly impacts energy levels, immune function, and inflammation, all of which are crucial for performance and recovery in sports.
