Enzyme bioavailability complex delivering compounds through biological tissue
Phase 01 — Deliver
16-Enzyme Bioavailability Complex

Get Every Ingredient to Its Exact Target

Good ingredients fail if they can't get where they need to go. NutraFlow's 16-enzyme Bioavailability Complex breaks each compound down to the exact size needed to cross tissue barriers — so active ingredients reach deep joint tissue, not just your stomach.† This is what it means to truly Deliver.

Fibrin protein strands encasing uric acid crystals in joint tissue
Phase 02 — Unlock
2,500 GDU Bromelain + Serrapeptase

Break the Barrier Nothing Else Can Touch

Uric acid deposits may accumulate around joint tissue, surrounded by a fibrin protein layer that many supplements don't address. Bromelain and Serrapeptase are enzymes studied for their ability to support fibrin breakdown.† Unlock that barrier, and everything that follows can actually reach its target.

Tart Cherry · Celery Seed · Chanca Piedra

Clear Uric Acid From the Inside Out

Most supplements stop in the gut. NutraFlow carries Tart Cherry, Celery Seed, and Chanca Piedra directly into joint tissue — where they support healthy uric acid clearance,† kidney filtration,† and normal uric acid levels from multiple angles.† That's what it means to truly Absorb.

Keep Your Joint Environment in Balance

Joint tissue may continue to need support even after discomfort eases. Quercetin and Boswellia support a normal inflammatory response,†† Resveratrol promotes healthy oxidative balance,† and Rose Hips support connective tissue health.† Chelated Zinc and Copper support optimal mineral absorption.

"I was pretty skeptical honestly — I've tried plenty of supplements that went nowhere. After a couple of weeks I started noticing I was moving around easier, especially first thing in the morning. Three months in and it's just part of my routine now."

"About six weeks in I went for a routine checkup and my doctor said whatever I was doing, keep it up. I didn't go into the whole supplement thing — I just said I'd made some changes. I'll take it."

"Had a pretty rough stretch with my joints last spring and started taking this while I waited to get in with my doctor. After about a week I started feeling more like myself. I've kept it up daily since — mostly just to stay ahead of things."

"I've cycled through a few different supplements over the years and most didn't stick. This one did. My joints feel less stiff in the mornings, I'm sleeping better, and I just feel more comfortable overall. Three months and counting."

Enzyme complex powder and capsules — Phase 01 bioavailability system
80,000 HUT · Protease I & II

Protease Complex

Dual-Protease Bioavailability System

How It Supports Joint Health

Protease I and II form the core of the Phase 01 NutraFlow™ Delivery System. These enzymes break down peptide bonds in dietary proteins, freeing active compounds for rapid systemic absorption — increasing co-administered botanical bioavailability by up to 60%.

Lipase enzyme — fat-soluble compound carrier in Phase 03
6,000 FIP · Fat-Soluble Carrier

Lipase

Phase 03 Delivery Enzyme

How It Supports Joint Health

Lipase catalyzes the breakdown of dietary fats and ensures fat-soluble Phase 04 compounds — Quercetin and Resveratrol — are properly emulsified and absorbed through the intestinal wall rather than being excreted unused.

Fresh papaya cross-section — Papain cysteine protease source
3,000,000 PU · Papaya-Derived

Papain

Carica papaya · Cysteine Protease

How It Supports Joint Health

A powerful plant-derived cysteine protease, Papain degrades fibrous protein structures and facilitates trans-membrane transport of botanical actives. It also has independent anti-inflammatory activity — modulating NF-κB pathways and reducing pro-inflammatory cytokines in arthritic tissue.

Bromelain

Ananas comosus · Standardized Extract

How It Supports Joint Health

A proteolytic enzyme that works in Phase 01 to support the breakdown of fibrin protein barriers.† At 2,500 GDU, Bromelain supports the delivery of active ingredients deeper into joint tissue where they can do the most good. Most supplements skip this step entirely.

Serrapeptase

Serratia E-15 · Silkworm Enzyme

How It Supports Joint Health

Originally discovered in silkworms dissolving cocoon walls, Serrapeptase is a proteolytic enzyme that breaks down non-living protein matter. In Phase 01, it works alongside Bromelain to fully degrade the fibrin barrier and reduce periarticular inflammation simultaneously.
