REGULAR MAGNESIUM OXIDE
0ppmNo active oxygen
Most magnesium supplements end at the mineral. Let Loose doesn't.
We start with magnesium oxide — an osmotic mineral that draws water into the colon to soften stool and support regularity — and then put it through our proprietary ozonation process, creating a highly ozonated form of magnesium with measurable active oxygen. The result is a formula designed to support gentle, effective elimination from more than one angle.
Active oxygen content measured by iodometric titration, manufacturer lab testing, 2026.
Active oxygen is what makes an “ozonated” magnesium actually ozonated. We submitted Let Loose and the two most recognized alternatives to our manufacturer's laboratory and ran iodometric titration — the standard analytical method for quantifying active oxygen content in a dosed supplement.
Here's what came back:
No active oxygen
Baseline ozonated magnesium
13× more than competitor
In plain English: magnesium oxide does the proven osmotic work — drawing water into the colon to soften stool and support regularity. What makes Let Loose different is our proprietary ozonation process, which creates a highly ozonated form of magnesium with 13× more measurable active oxygen than the leading ozonated competitor tested.
Ozonation is a proprietary process that incorporates oxygen into our magnesium formula using medical-grade ozone. The result is our unique ozonated magnesium ingredient, developed to support digestive health and regularity. That's what makes Let Loose different.*
Magnesium oxide draws water into the colon to help soften stool and support regular bowel movements.1
Our unique manufacturing process enhances magnesium oxide using medical-grade ozone to create our patented ozonated magnesium ingredient.
Together, these innovations are designed to support digestive health, regularity, and everyday gut wellness.*2,3
Most of the constipation category talks about magnesium. We wanted to explore whether our proprietary ozonation process could take it one step further. Here's some of the peer-reviewed research that inspired our technology.
The studies below include laboratory and preclinical research on oxygen- and ozone-based approaches. They are provided as scientific background for our proprietary ozonation technology and are not clinical studies of Let Loose capsules.
Ozone is a highly reactive form of oxygen that researchers are studying for its effects on the intestinal environment. In a 2025 peer-reviewed study published in the Journal of Medical Microbiology, ozonated water administration in a preclinical dysbiosis model altered microbial populations and supported markers of intestinal barrier function through the SIRT1–Nrf2/HO-1 signaling pathway.3
Plain English: Researchers are studying how ozone-based approaches may influence the gut environment and microbiome. More research is needed to understand how these findings translate to oral ozonated magnesium.
The gut barrier is a single-cell-thick layer held together by “tight junction” proteins. When functioning normally, it helps regulate what passes from your digestive tract into your body. Preclinical research has investigated how ozone-based approaches may interact with pathways involved in intestinal barrier integrity. In one 2025 study, researchers observed preservation of barrier function through activation of the aryl hydrocarbon receptor and modulation of tryptophan metabolism.4 A separate preclinical model found that medical ozone influenced the body's endogenous antioxidant defenses in intestinal tissue.5
Plain English: Researchers are continuing to explore how ozone-based approaches may support the intestinal barrier.
Ozone's interactions with microorganisms have been well characterized in laboratory research. Studies show that ozone can interact with microbial cell membranes and other cellular structures through oxidative mechanisms.6,7 Researchers are continuing to investigate how these properties may translate to applications involving the digestive environment.
Plain English: Ozone has well-documented interactions with microorganisms in laboratory settings. What that means for oral ozonated magnesium in humans still needs to be studied.
Preclinical and clinical research has investigated how controlled ozone-based therapies may influence the body's endogenous antioxidant pathways, including Nrf2, glutathione, and superoxide dismutase.8 While these findings are interesting, additional research is needed to understand how they may apply to oral dietary supplements.
Plain English: Scientists are investigating how controlled ozone exposure may interact with the body's own antioxidant defense systems.
We're keeping the existing RCT evidence on this page because it's the strongest human data for the mineral itself. The reframe: this is the baseline — what magnesium oxide does on its own, before we add active oxygen.
In a 2019 randomized, double-blind, placebo-controlled trial published in the Journal of Neurogastroenterology and Motility, magnesium oxide improved overall symptoms in 70.6% of participants with occasional constipation, compared with 25% on placebo.1 A 2020 follow-up RCT confirmed it: magnesium oxide matched the efficacy of senna (a stimulant laxative) at roughly 68% response, with a different, non-stimulant mechanism.9
Now imagine that baseline — plus 28,186 ppm of active oxygen in every dose.

Let Loose pairs an RCT-studied osmotic mineral with our proprietary ozonation technology and 13× more measurable active oxygen than the leading ozonated competitor tested. Magnesium oxide helps draw water into the colon to soften stool and support regularity. Our ozonation process is what makes Let Loose different from ordinary magnesium oxide—and we're continuing to study the additional role this unique chemistry may play in digestive health.*

You don't actually get nourished by what you eat. You get nourished by what you digest.
Modern meals are more complex than the digestive system they're landing in. Processed ingredients, dense proteins, refined oils, engineered foods — all of it asks more of your enzymes than nature ever planned for. Koji Digestive Enzymes help your body break food into the small, usable pieces it actually needs. Meals feel lighter. Digestion runs smoother. Your body gets more out of the food you're already eating.
Walk down the enzyme aisle and most labels look impressive: “18 enzymes!” “22-enzyme complex!” Flip them over. The total enzyme content is often around 85 mg, spread across a dozen or more ingredients in trace amounts. That's enough to list on a label. It's not always enough to do the work of digesting a real meal.
Here's the difference:
| Typical Mass-Market Blend | Let Loose Koji Digestive Enzymes |
|---|---|
| ~85 mg total blend | 355 mg per capsule |
| Dozens of enzymes listed, each in trace amounts | 16 enzymes dosed at activity levels sized for real meals |
| Often listed by weight only | Disclosed in enzyme activity units (HUT, DU, FIP, etc.) |
| Commodity sourcing across multiple suppliers | Traditional Japanese Koji fermentation, 150+ year process |
An enzyme's weight tells you how much material is in the capsule, but that includes inactive components too. Activity units tell you how much digestive work it can actually perform. HUT measures protease, DU and SU amylase, FIP lipase, GALU lactase, and ALU alpha-galactosidase. These are standard units used to measure enzyme function. We list every one on our label.
You take it with water a few minutes before eating. The capsule dissolves in your stomach, releasing the Koji enzyme blend into the digestive tract right as food arrives. Each enzyme works on a specific part of the meal.
Koji-derived fungal proteases are naturally acid-stable and remain active under gastric conditions. Our formula includes acid-stable proteases that start breaking protein apart before it reaches the small intestine.
Sixteen enzymes work in parallel — proteases on protein, amylases on starch, lipases on oil, lactase on dairy, cellulases on vegetables, alpha-galactosidase on beans.
Better breakdown means nutrients locked inside plant cell walls, protein matrices, and fat droplets are released where your gut can absorb them.
| Enzyme | Activity per capsule | What it breaks down |
|---|---|---|
| Protease I | 20,000 HUT | Proteins — meats, dairy, legumes |
| Protease II | 50,000 HUT | Proteins — broad pH range |
| Protease (Acid-Stable) | 200 SAPU | Starts protein breakdown in the stomach |
| Peptidase DPP-IV | 72 DPPIV | Peptides and gluten-derived fragments |
| Peptidase | 4,000 HUT | Shorter protein chains |
| Alpha Amylase | 12,000 DU | Starches — bread, rice, potato |
| Alpha Galactosidase | 300 GALU | Complex sugars in beans, cruciferous veg |
| Beta Glucanase | 50 BGU | Beta-glucans in oats, barley |
| Invertase | 400 SU | Sucrose |
| Lactase | 400 ALU | Lactose |
| Pectinase | 14 ENDO PG | Pectin in fruits and vegetables |
| Cellulase | 2,000 CU | Cellulose — plant cell walls |
| Hemicellulase | 2,000 HCU | Hemicellulose — plant fiber |
| Xylanase | 300 XU | Xylan — grain fiber |
| Lipase I | 100 FIP | Fats — short/medium-chain |
| Lipase II | 1,300 FIP | Fats — broad-chain |
Activity units: HUT = protein-breaking units. DU = starch-breaking units. FIP = fat-breaking units. GALU, SU, ALU, BGU, CU, HCU, XU, ENDO PG, DPPIV, SAPU = specialist units for specific substrates.
One capsule is formulated to support digestion of roughly 40–60 g of protein, 40–80 g of carbohydrate, and 20–25 g of fat. These estimates are biochemical modeling, not clinical claims; actual digestion varies by person.
Koji (Aspergillus oryzae) has been cultivated in Japan for over a millennium for miso, soy sauce, and sake. A single Koji culture naturally secretes many hydrolytic enzymes in parallel.
A single fermentation produces proteases, amylases, lipases, cellulases, hemicellulases, xylanases, pectinases, peptidases, and esterases.
Plain English: Koji gives you a whole team, not a lineup of solo players.
In in-vitro models of human digestion, fungal enzymes remain active under gastric conditions. Acid-stable proteases can start breaking down protein in the stomach phase.
Plain English: They start working the moment you swallow.
Jokichi Takamine patented Taka-diastase, a Koji-derived digestive enzyme preparation, in 1894. Today, A. oryzae is GRAS-designated by the FDA for specified enzyme preparations.
Plain English: This isn't a trend ingredient.
Traditional fermentation generates cellulases, hemicellulases, xylanases, pectinases, esterases, and additional peptidases that help break apart complex food structures.
Plain English: Before the main enzymes can do their job, something has to open the food up. Koji does both.
The category has become well-studied over the last decade. Here's what peer-reviewed human trials have shown.
A 2024 randomized, double-blind, placebo-controlled crossover study of 25 adults with daily post-meal bloating reported reductions in abdominal distension of 58% at 30 minutes and 68% at 90 minutes compared with placebo; 80% of participants saw a measurable reduction.
A 2023 randomized, double-blind, placebo-controlled trial of 120 adults with digestive symptoms reported improvements in quality of life, sleep quality, and post-meal discomfort over two months. Another RCT reported improvements in bloating, fullness, and post-meal distress.
A 2022 INFOGEST in-vitro study demonstrated that fungal-derived digestive enzymes improve macronutrient hydrolysis under simulated gastric and small intestinal conditions. Our formula is built on the same class of enzymes, at 355 mg per capsule.
Take one Let Loose Koji Digestive Enzymes capsule before your two largest meals of the day. For heavier meals, take two. Eat what you want. Just digest it better.
