About this test

This is a bundle rather than a standalone test: an at-home stool sample analysed for your gut microbiome, described by Stride as covering 5 reports across metabolism, digestion and related areas, packaged with three months of GS-01, a daily supplement containing probiotic strains and prebiotic fibre. The stool sample is collected at home and posted to the lab.

Stride does not publish how many specific bacterial markers or species the microbiome analysis measures, which is why it scores low on clinical depth: without that detail it is not possible to judge how thorough the analysis is. There are no comparable bundles in our data, so no price comparison can be made.

It scores reasonably for clarity, since Stride describes what is included and the collection method, though not the biomarkers measured or the report format. Collection convenience is middling because, while the stool sample avoids any needle, the 20 to 25 day turnaround is slower than most other tests we track. It scores in the middle for results and follow-up: a consultation is included, but results are not doctor-reviewed.

Who is it for?

This suits people who want to pair a gut microbiome readout with an ongoing daily supplement, and who are comfortable with a longer wait for results than most other tests. Because it is a bundle, it is a bigger commitment than a one-off test.

If you only want the test itself without the supplement, Stride's standalone Optimal Biome test covers the same stool analysis at a lower price. If detailed markers matter to you, be aware that Stride does not publish the specific bacterial species or markers measured in either version.

How it works

You collect a stool sample at home using Stride's kit and post it to the lab; results are returned in around 20 to 25 working days. Alongside the test, you receive three months' supply of GS-01, a daily supplement combining probiotic strains with prebiotic fibre, taken as two capsules a day with food. A one-to-one consultation is included, though results are not reviewed by a doctor.

Our editorial score

Compare Health Test Score Microbiome test bundled with a 3-month supplement supply
Editorial confidence: 8.0/10

The Gut Stack combines Stride's Optimal Biome stool test with three months of its GS-01 pre- and probiotic supplement for £259.35. Stride does not state how many markers the microbiome analysis covers, and with no comparable bundles in the data, it is difficult to judge whether the price reflects good value. Turnaround is longer than most other tests, at 20 to 25 days.

  • Clinical depth 3.5/10

    The provider does not state how many biomarkers are measured, so depth cannot be assessed.

  • Results and follow-up 6.0/10
