Biome Secret isn't a trend. It's a complete, satiating, blood-sugar-steady meal built on decades of nutrition science — and reformulated 84 times until every gram earned its place.
A grabbed pastry or skipped breakfast spikes blood sugar, leaves you under-nourished, and has you hungry again in ninety minutes. The crash drives the next craving.
One nutritionally complete meal — high protein, viscous fiber, 28 vitamins and minerals — that keeps you full, keeps blood sugar steady, and makes the day's calorie math easier to hold.
Every claim below is mechanistic and evidence-led. Where the science is still mixed, we say so. We don't sell miracles — we sell a better default.
Most shakes are protein with a vitamin dusting. Biome Secret is formulated to stand in for a whole meal — enough protein, fiber, and micronutrients to be nutritionally complete on its own.
That completeness matters for results. In a systematic review and meta-analysis of 23 randomized trials (7,884 adults), diets that incorporated meal replacements produced greater weight loss at one year than food-based programs — a mean difference of 1.44 kg.1 Partial meal-replacement plans have also been shown to produce significant, sustainable weight loss while improving weight-related risk factors.2
Protein and viscous fiber are the two most satiating things you can put in a meal — and they work through measurable gut-hormone signals, not willpower.
Higher-protein meals raise the appetite-suppressing hormones GLP-1, CCK, and PYY while lowering ghrelin — a hormonal pattern repeatedly linked to reduced hunger and lower food intake.3 A meta-analysis of randomized trials found protein suppresses every dimension of appetite — hunger, fullness, satiety, desire to eat, and how much you expect to eat next.4 Viscous soluble fibers add a second, physical layer: they thicken the contents of the gut, slow emptying, and prolong fullness.5
A fair caveat: when meals are precisely matched for calories, these hormone shifts don't always translate into eating less at the very next meal. We frame protein and fiber as supporting appetite control across a day — not a guarantee at any single sitting.
The viscous fiber that keeps you full does a second job: it flattens the blood-sugar curve of the meal.
Viscous soluble fibers — like the guar, psyllium and acacia in our blend — raise the viscosity of food in the gut, slowing gastric emptying and the absorption of glucose, which blunts the post-meal blood-sugar rise.5 In a meta-analysis of 17 randomized trials, viscous soluble fiber significantly lowered HbA1c (a 3-month blood-sugar average) by 0.47% and fasting glucose by 0.93 mmol/L, alongside reductions in total and LDL cholesterol.6 Steadier glucose means steadier energy — and fewer of the crashes that trigger the next craving.
The shake pairs prebiotic fiber (the food) with live probiotic strains (the workforce) — a deliberate one-two for gut health.
Prebiotic, fermentable fibers reach the colon intact — food for your resident bacteria.
Bacteria turn that fiber into short-chain fatty acids like butyrate that nourish the gut lining.
Live L. acidophilus & B. longum help tip the ecosystem toward beneficial strains.
In a meta-analysis of randomized trials, probiotic blends containing Bifidobacterium longum or Lactobacillus acidophilus reduced abdominal pain scores versus placebo.7 Mechanistically, probiotics help rebalance gut flora and feed short-chain fatty acid production, which supports the gut barrier and may ease bloating.7
Probiotic effects are strain-specific and vary between people. We name our strains rather than hiding behind a "proprietary blend," and we make gut-comfort claims, not cures.
Protein + viscous fiber raise satiety signals.
A flatter glucose curve means fewer crash-driven cravings.
Lower hunger makes a modest calorie deficit sustainable.
Sustained deficit is what actually drives fat loss.
There is no metabolic magic here — and we won't pretend otherwise. Fat loss comes from a sustained energy deficit. What Biome Secret does is make that deficit liveable: by blunting hunger and steadying blood sugar, it removes the two things that derail most diets. That's also why meal-replacement diets out-perform food-only diets in head-to-head trials,1 and improve cardiometabolic markers in people with pre-diabetes.11
Every active is named, dosed, and sourced on purpose — whole-food nutrients, viscous fibers, live cultures and micronutrients working together.
The shake is the foundation. The capsules are targeted boosters for people who want to push further on metabolism or comfort.
Green-tea catechins (EGCG) with caffeine, plus L-carnitine and guarana. In a meta-analysis, catechin–caffeine combinations raised 24-hour energy expenditure by roughly 4.7% and increased daily fat oxidation by about 16% versus placebo.8 Green-tea extract has shown thermogenic effects beyond caffeine alone.9
Effects are modest and work best alongside the shake and an active routine.
Explore Metabolism Booster+Digestive enzymes — bromelain, papain, protease and cellulase — plus probiotics. Proteolytic enzymes break dietary protein into smaller, more absorbable fragments and have long been used to ease indigestion and bloating, with anti-inflammatory activity that may reduce gas and discomfort.10
Best for occasional bloating after big or protein-heavy meals — not a treatment for medical conditions.
Explore Bloating Relief+A formula is only as honest as its manufacturing. Ours was built with five specialist partners and reformulated 84 times — and we moved production to the EU because the facilities we visited elsewhere couldn't meet our purity bar.
Every batch is third-party tested for heavy metals, contaminants, and label accuracy. We publish what's in the product, name our strains and doses, and flag where the science is still emerging. Trust is earned in the details.
