Our Verdict
A clean, minimalist 3-in-1 (probiotic + prebiotic + postbiotic) built around two well-studied branded strains — Lactobacillus rhamnosus LGG and Bifidobacterium lactis BB-12. Includes PreforPro prebiotic bacteriophage and tributyrin postbiotic. Clean ingredient transparency, no proprietary blends, delayed-release capsule. The honest critique: until 2024 Ritual had run zero clinical trials on the actual Synbiotic+ product — only cited general strain research. First product-level trial (NCT06834984) is now ongoing.

About Ritual
Ritual is Seed's most direct competitor. The LGG and BB-12 strains they chose are genuinely well-studied — that's a real plus. But calling a product 'backed by 100+ publications' when those publications are on the underlying strains, not the finished product, is the exact marketing move the category is full of. Ritual is running its first Synbiotic+ trial now, which will be meaningful evidence whenever it publishes.
