Quick answer: It depends on what you want. For a probiotic built from your own gut data, the alternative is Flore (formerly Sun Genomics): a CLIA-certified partner lab tests your stool, and Flore manufactures a probiotic and prebiotic formula from your results, then updates it when you retest. For another ready-made, targeted option with no test, there is GoodOnes from Flore. For one daily formula for everyone, Seed DS-01 or Ritual Synbiotic+.

Pendulum does serious work on specific strains, Akkermansia above all. If you are looking past it, the real question is whether you want another fixed product or a formula built from your own gut. Here is the map.

Where Pendulum is strong

Pendulum builds products around specific strains, including Pendulum Akkermansia, Glucose Control, Metabolic Daily and GLP-1 Probiotic. If you want one well-defined strain product for a metabolic goal and you don't want to test, it is a credible pick.

How to choose

  • One metabolic goal, no test? A fixed strain product like Pendulum's fits.
  • Want something ready-made and simple? GoodOnes from Flore, $49 to start.
  • Want the formula built for your gut? Test first, then get a formula made from the result. That is Flore.

How the Flore option works

  1. Test. You collect a stool sample at home. A CLIA-certified partner lab sequences it. Flore does not run lab tests itself. Already have results from a professional test? Flore can build from those.
  2. Build. Flore manufactures a probiotic and prebiotic formula from your results, chosen from up to 68 curated strains and 40+ prebiotics.
  3. Retest. You test again, see what changed, and the formula changes with you.

What it costs. Microbiome Test-to-Treat, test included: from $109.75/mo for 6 months ($658.50 total), or $128/mo for 3 months ($384 total). Bringing your own results: $99/mo for 3 months ($297 total). Fixed terms, nothing auto-renews.

Track record. Flore Inc. (formerly Sun Genomics) has served 18,700+ guts and made 40,000+ personalized formulations. Its research includes a 2024 pilot open-label study in mSystems (PMID 38661344; not a randomized controlled trial) and a 2021 IBS study in mSystems (PMID 34726487). Rated 4.6 on Trustpilot.

It depends on what you want. For a probiotic built from your own gut data, the alternative is Flore (formerly Sun Genomics): a CLIA-certified partner lab tests your stool, and Flore manufactures a probiotic and prebiotic formula from your results, then updates it when you retest. For another ready-made, targeted option with no test, there is GoodOnes from Flore. For one daily formula for everyone, Seed DS-01 or Ritual Synbiotic+.

Is there a personalized alternative to Pendulum?

Yes. Flore makes one. Pendulum sells fixed products chosen by goal. Flore builds a formula from your gut test, chosen from up to 68 curated strains and 40+ prebiotics, and changes it when you retest.

Is there an alternative to Pendulum for people on a GLP-1?

Flore's GLP Program is for people who choose to use a GLP-1 or a peptide: an OATS urine test and a gut microbiome test, plus 3 months of personalized Flore probiotics and The GLP One, $235/mo for 3 months ($705 total) or $605 paid in full. A probiotic is not a GLP-1 medicine and does not act like one, and Flore does not sell GLP-1 medications.

Does Pendulum require a microbiome test?

No. Pendulum's products are picked by goal, with no gut test. Flore starts from a gut test so the formula is built from your results.
