A probiotic built for high-protein athletes — every strain selected from sports nutrition research, dosed at the amounts shown effective in clinical trials.
Improved time-to-exhaustion, decreased body fat, and increased muscle mass in a dose-dependent manner across 5+ RCTs with 200+ total subjects.
Improved plasma BCAA and total amino acid levels, increased leg press 1RM and vertical jump power vs. placebo in a double-blind RCT at AIIMS Delhi (n=70). Also 22+ studies for digestive health.
Significant reductions in CK, myoglobin, and hs-CRP after exercise-induced muscle damage. Preserved strength output (CMJ, IMTP) at 24h and 48h. Heat-killed form matched or outperformed live on multiple endpoints.
You eat 150+ grams of protein a day. You train five or six days a week. You take pre-workout, creatine, protein shakes. Your gut handles more daily stress than the average person's — and most probiotics were designed for the average person. This one wasn't.
"I started Koya after spending months reviewing probiotic literature and finding that most products don't use the strains or dosages that clinical trials actually validated. This formula is what I wanted to find on the shelf but couldn't."
— Founder, Koya ProbioticsWe start in PubMed, not trend reports. Only strains with published human randomized controlled trials make the shortlist.
We evaluate study quality, effect sizes, and replication. Single-study strains get flagged. Independent validation gets prioritized.
We match the exact dosages used in clinical protocols. If a trial used 2 billion CFU, that's what goes in the capsule. No fairy-dusting.
Every ingredient addresses a distinct endpoint — chosen for its published human clinical trial data in athletes and active adults, not marketing claims.
Lactiplantibacillus plantarum TWK10
The performance anchor. Supports exercise endurance, lean body composition, and training capacity across multiple dose-response RCTs with 200+ total subjects.
Huang et al., Nutrients, 2019; Cheng et al., 2023; Lee et al., 2021 — 200+ subjects
Bacillus coagulans Unique IS-2
A spore-forming probiotic that produces proteases in the small intestine. Supports amino acid bioavailability from dietary protein in a published double-blind RCT, plus 22+ studies for digestive health.

Lacticaseibacillus paracasei PS23 (heat-killed postbiotic)
The strongest recovery strain available. A large double-blind RCT (n=105) reported reduced muscle damage markers and preserved strength output at 24h and 48h post-exercise. Heat-killed form matched or outperformed live.
Huang et al., Nutrients, 2022 — heat-killed outperformed live on multiple endpoints
Most probiotics list 15–20 strains with no human clinical data and hide doses behind proprietary blends. We use three — each backed by published RCTs in athletes and active adults — at the exact dosages shown effective in research.*
Why a heat-killed postbiotic? The PS23 recovery trial (n=105) directly compared heat-killed vs. live forms and found heat-killed matched or outperformed live on multiple endpoints. Postbiotics offer superior shelf stability, zero strain-interaction risk, and no viability concerns — a formulation advantage, not a compromise.
Every strain is backed by published, peer-reviewed human clinical trials. We don't rely on animal studies or in-vitro data alone.

We've completed initial formulation research and are seeking manufacturing partners for a capsule-format product. We're looking for partners who share our commitment to clinically-backed formulations.
