Ingredients & Science

The evidence behind every capsule

Most supplements are built on a marketing claim and an underdosed ingredient. Kincadence is built the other way around — we start from the human evidence, name the exact branded form, and dose it to match the studies. Here is the science, in full, including where it is still early.

Named, branded activesWe use identified, third-party-tested branded ingredients — not anonymous ‘proprietary blends.’
Doses that match the researchWhere a study used a specific dose, we aim to match it — not a fraction of it.
Mechanism firstWe explain how each compound works on a known biological pathway, with citations you can look up.
Honest about the limitsWhen evidence is early, observational, or mixed, we say so — on this page.

Kincadence Biopeptide

Calm · Sleep · Stress support — one clinically studied milk peptide.

α-casozepine — milk protein hydrolysate (α-casozepine)

150 mg · contains milk
How it works. α-casozepine, a peptide from αS1-casein, binds the benzodiazepine site of the GABAA receptor — the brain's primary calming system — supporting relaxation without sedation.
  • Built on the same brain pathway your body already uses to wind down (GABAA), so it supports calm without acting as a hormone.
  • Studied at the exact 150 mg serving used in Kincadence Biopeptide.
  • In a randomized, double-blind, placebo-controlled trial, the milk peptide helped support faster sleep onset, measured objectively by polysomnography.1
  • In healthy women under everyday stress, 150 mg/day for 30 days helped support how they coped across emotional, digestive, and other everyday-comfort domains.2
  • Non-sedative and non-habit-forming — no melatonin and no added hormones.
  • Acute human work explored a calmer physiological response to short-term mental and physical stressors.3
Human RCTChang et al., Clinical Nutrition 2024 — 4-week double-blind RCT: the peptide shortened polysomnography-measured time-to-fall-asleep vs placebo. PMID 39541860
Human RCTKim et al., Eur J Clin Nutr 2007 — double-blind crossover in 63 women: 150 mg/day for 30 days improved self-reported stress-symptom scores. PMID 17136040
Human RCTMessaoudi et al., Eur J Nutr 2005 — small acute human study of the physiological stress response (exploratory/mechanistic). DOI 10.1007/s00394-004-0534-7

Evidence base is genuine but still early-stage; we describe calm, relaxation, and healthy sleep onset only — never a treatment for any sleep or mood condition.

Kincadence Mobility X

Four researched ingredients at transparent, effective doses — for joint comfort, mobility & flexibility.

Undenatured type II collagen

40 mg · the differentiated hero
How it works. Undenatured (native) type II collagen works by oral tolerance — small amounts interacting with gut-associated immune tissue to help the immune system ease its response to joint cartilage. A mechanism entirely distinct from glucosamine.
  • Works by an immune oral-tolerance mechanism — not a building-block or anti-friction claim.
  • The one ingredient here studied head-to-head against glucosamine + chondroitin for joint comfort and function.
  • Must be native/undenatured to work — we require a COA verifying undenatured content (ELISA).
  • On-brand for the ‘Move’ pillar and dosed to the level used in research.
Human RCTLugo et al., Nutrition Journal 2016 — randomized, double-blind: 40 mg/day undenatured type II collagen improved knee joint comfort and function vs placebo, and outperformed glucosamine + chondroitin. PMID 26822714

We describe joint comfort, mobility and flexibility only — never arthritis treatment. Undenatured collagen is our differentiated hero; the rest of the stack covers comfort from other angles.

Curcumin (95% curcuminoids)

500 mg · paired with black pepper
How it works. Curcumin, the active from turmeric, is one of the most-researched botanicals for joint comfort, studied for its role in the body's normal inflammatory-signalling balance. It absorbs poorly alone — so it is paired with piperine.
  • One of the deepest joint-comfort trial bases of any botanical, with meta-analyses pooling multiple RCTs.
  • Supports the body's normal inflammatory response — a structure/function role, not disease treatment.
  • Poorly absorbed on its own, which is why we include black-pepper piperine.
  • A household-name active people already trust for everyday joint comfort.
Human RCTDaily et al., J Med Food 2016 — systematic review & meta-analysis of RCTs: turmeric/curcumin extracts (~1 g/day, typically 8–12 weeks) improved joint-comfort symptoms vs placebo. PMID 27533649

Curcumin evidence is genuine, but we frame it as everyday joint-comfort support — not a treatment for arthritis or any joint disease.

Boswellia serrata (30% AKBA)

100 mg · fast-onset comfort
How it works. Boswellia is a resin extract standardized to AKBA (acetyl-keto-beta-boswellic acid), studied for the 5-LOX pathway in the body's normal inflammatory signalling — and valued for how quickly its comfort support is often felt.
  • A fast-onset botanical — comfort support is often noticed within the first week.
  • Standardized to AKBA, the fraction most associated with its activity.
  • Covers collagen's slower ramp, so the stack supports comfort early and over time.
  • Robust and well-tolerated as an effectively-dosed generic extract.
Human RCTSengupta et al., Arthritis Research & Therapy 2008 — randomized, double-blind: AKBA-standardized boswellia improved knee joint comfort and physical function vs placebo, with benefit as early as ~7 days. PMID 18667054

Structure/function joint-comfort support only. We standardize to AKBA and dose it to the researched range, transparently on the label.

Black-pepper extract (95% piperine)

5 mg · absorption enhancer
How it works. Piperine slows the body's rapid first-pass breakdown (glucuronidation) of co-ingested compounds, helping more of the curcumin get absorbed — the generic route to bioavailability.
  • Included to help the curcumin absorb, instead of passing straight through.
  • Works by slowing the rapid clearance (glucuronidation) of co-ingested curcumin.
  • A small, standardized inclusion long used to boost polyphenol uptake.
  • In a classic human study, 20 mg piperine sharply increased curcumin absorption.
Human RCTShoba et al., Planta Med 1998 — human PK study: 20 mg piperine increased curcumin bioavailability ~2000%. PMID 9619120

The absorption figure is specific to curcumin. If you take prescription medication, piperine can affect drug metabolism — check with your physician.

Hyaluronic acid

80 mg · supporting note
How it works. Hyaluronic acid is a natural component of the fluid and connective tissue that keep joints cushioned and gliding. It is included as a supporting ‘lubrication / cushioned-feel’ note in the stack.
  • A natural part of the joint's own lubricating and cushioning matrix.
  • Included to support a smoother, more cushioned feel.
  • Kept as a supporting note, not a primary claim driver.

Generic oral HA lacks the branded-matrix evidence, so we keep it as a supporting note and don't build a primary claim on it — honest by design.

Kincadence Akkermansia

A single, honestly-dosed pasteurized postbiotic for the gut barrier & metabolism — plus zinc.

Pasteurized Akkermansia muciniphila (postbiotic)

10 billion cells (1010) · pasteurized
How it works. Akkermansia is a keystone gut bacterium that lives in the intestinal mucus layer, feeding on mucin and signalling the gut to renew it — a robust mucus layer plus intact tight junctions is what makes the gut barrier strong. The pasteurized (heat-inactivated) form, and its membrane protein Amuc_1100, carry the metabolic signal and are more stable and better-studied in humans than the live cell.
  • Supports the gut's protective mucus (mucin) layer and the tight junctions that keep the gut barrier robust.
  • Helps generate beneficial short-chain fatty acids (acetate, propionate) that feed other healthy gut bacteria and support microbial diversity.
  • In a 3-month human RCT, pasteurized Akkermansia was associated with ~30% better insulin sensitivity, ~9% lower total cholesterol, and reductions in fat mass and markers of metabolic and liver function vs placebo.11
  • Pasteurized outperformed live bacteria in that study — and is far more stable in a capsule.
  • Dosed at the exact 1010 cells used in the human study, in a delayed-release enteric capsule that protects it through stomach acid.
Human RCTDepommier et al., Nature Medicine 2019 — 3-month randomized, double-blind, placebo-controlled exploratory study in 32 overweight/insulin-resistant adults: pasteurized A. muciniphila improved insulin sensitivity and reduced insulinemia, total cholesterol and markers of liver dysfunction/inflammation vs placebo. PMID 31263284
PreclinicalPlovier/Cani et al., Nature Medicine 2017 — identified the pasteurized cell and the Amuc_1100 membrane protein as carrying the gut-barrier and metabolic benefit (mouse + mechanism). PMID 27892954

This is an exploratory pilot RCT (n=32 completers) and the species-level evidence is still early; the GLP-1/appetite-signalling mechanism is largely preclinical. We describe gut-barrier, microbiome, appetite and healthy-metabolism support — never weight-loss-drug or disease claims. Percentages are findings for the ingredient in that study, not guaranteed outcomes from this product.

Zinc (bisglycinate / gluconate)

15 mg elemental
How it works. Zinc is an essential mineral and a cofactor for hundreds of enzymes, including those in macronutrient metabolism and immune-cell function — roles recognised by authority-reviewed structure/function claims.
  • Contributes to normal macronutrient metabolism (carbohydrate, fat and protein).
  • Contributes to the normal function of the immune system.
  • Contributes to the protection of cells from oxidative stress.
  • A clean, modest 15 mg dose — the one supporting actor alongside the postbiotic.

Zinc's roles in metabolism, immunity and antioxidant defense are well-established, authority-recognised structure/function claims.
