    • Difference in purpose

      InnerBuddies is designed specifically to evaluate the gut microbiome ecosystem from stool and to translate that into nutrition and microbiome-targeted probiotic/prebiotic recommendations. Bloodtesting.nl is centered on blood biomarker testing, which can help assess systemic health signals that may relate to gut-related issues, but it does not directly measure the gut microbiome in the same way.

    • Difference in measurement

      With InnerBuddies, your results are driven by stool sequencing (16S DNA sequencing and shotgun metagenomics) plus your 3-day food diary to connect gut patterns with your reported diet. With Bloodtesting.nl, what you learn depends on the chosen blood panel—results reflect blood markers rather than microbial species/functions in stool.

    • Difference in Actionability

      InnerBuddies emphasizes actionable guidance tied to your data: personalized nutrition on a detailed level (individual food items with daily dosage) and probiotic/prebiotic suggestions based on scientifically validated strains. Blood testing reports can be actionable too, but the type of actions is more dependent on how the selected biomarkers are translated into recommendations.

    • Difference in Access

      InnerBuddies uses home stool sampling and a food diary you fill in, aiming for consumer-friendly interpretation. Bloodtesting.nl uses home blood sampling and typically produces biomarker-style outputs; it may feel more straightforward if you prefer not to track multiple days of food diary entries for microbiome matching.

    • Choose InnerBuddies if

      Choose InnerBuddies if your primary question is “what’s happening in my gut microbiome?” and you want recommendations that are directly mapped to your reported diet. It’s a good fit if you’re looking for detailed nutrition guidance (individual foods with daily dosage) and probiotic/prebiotic suggestions that are based on scientifically validated strains. It also fits if you plan to retest over time to see whether changes align with your gut-health goals.

    • Choose Bloodtesting.nl if

      Choose Bloodtesting.nl if you want blood-based markers to understand systemic factors that can influence overall health (and potentially gut-related symptoms) without focusing on stool microbiome analysis. It’s a good option if you prefer biomarker panels and want results that may be easier to discuss in a clinically familiar format. If you mainly need nutrients, inflammation-related indicators, or other systemic signals, a blood test panel may match your goal better.
