THE PRODUCTS.

ACV Gummies deliver the active compound in apple cider vinegar — acetic acid — in a concentrated, gut-friendly gummy format. Acetic acid supports stomach acid production, promotes healthy pH balance in the digestive tract, and assists the body’s natural fat-metabolism pathways. Unlike liquid vinegar, gummies bypass the enamel damage, throat burn, and “I’d rather not” taste problem. Each gummy delivers 500mg of ACV with added B12 and folate. Take two daily. Your gut does the rest.

ACV Gummies: 2 gummies daily, preferably before a meal.
Blood Sugar Support: 2 capsules daily with food. Best taken before your highest-carb meal.
Shroom Complex: 2 capsules daily with or without food. Morning is optimal for focus benefits.
Ashwagandha Formula: 1 capsule twice daily with meals. Morning and evening for sustained cortisol management.
Prebiotic Complex: 1 scoop (or 2 capsules) daily with water. Can be taken any time.
Probiotic Formula: 1 capsule daily on an empty stomach. First thing in the morning, 20 minutes before eating.
Daily MultiVitamin: 2 capsules daily with food to maximize absorption.

Consistency matters more than perfect timing. Pick a routine and stick to it.

Here’s the honest timeline:
Weeks 1–2: Reduced bloating, more regular digestion, less post-meal discomfort. Most users notice this first.
Weeks 4–6: Significant changes — improved energy, better nutrient absorption, visible reduction in abdominal bloat, more stable appetite.
Week 12 (full protocol): This is where the compounding effect hits. Gut microbiome rebalancing, sustained metabolic improvements, measurable changes in how you look and feel.

Your gut flora didn’t get wrecked overnight. Rebuilding it takes time. That’s why we sell multi-bottle stacks — the 12-week protocol delivers the most dramatic results.

No. That was the entire point of making them. The gummies use a natural apple-pomegranate flavor profile that masks the acetic acid without burying it in sugar. You get a tart, slightly tangy bite — not a shot of vinegar to the face. Each gummy contains only 1g of sugar. Most customers describe the taste as “sour apple candy.” If you’ve been choking down liquid ACV, this is the upgrade you didn’t know you needed.

Yes. The LeanScience line is engineered as a system. Each formula targets a different axis of gut health and metabolic function — there’s no redundant overlap or dangerous stacking risk. The ACV Gummies handle acid balance and digestion. Prebiotics feed the good bacteria. Probiotics replenish them. Shroom Complex supports immune signaling. Ashwagandha manages the cortisol-gut connection. Blood Sugar Support keeps glucose stable. The MultiVitamin fills nutritional gaps.

Start with 1–2 products if you prefer a gradual approach, then build your stack over time. The full 7-product protocol is for people who are done messing around.

Probiotics are live beneficial bacteria that colonize your gut. Think of them as reinforcements — new troops for your microbiome.
Prebiotics are specialized plant fibers that feed those bacteria. Think of them as fuel for the troops.

Taking probiotics without prebiotics is like hiring employees and not feeding them. Taking prebiotics without probiotics works — but only if your existing gut flora is healthy enough to benefit. For maximum impact, take both. That’s why we formulated them as separate products: so you can dose each independently based on your body’s needs.

HEALTH &
SAFETY.

Some users experience a mild adjustment period during the first 3–7 days. This can include slight bloating, increased gas, or changes in bowel frequency. This is normal — it’s your gut microbiome recalibrating. The prebiotics and probiotics are actively shifting your bacterial balance, and that transition isn’t always silent.

These effects typically resolve within a week. If you have a sensitive stomach, start with half doses for the first 5 days and ramp up. All LeanScience formulas use clinically studied ingredients at safe, published doses. No proprietary blends. No hidden stimulants.

Consult your physician before starting any supplement regimen, especially if you take prescription medication. This is not a legal disclaimer — it’s real advice. Blood Sugar Support in particular may interact with diabetes medications or insulin. Ashwagandha may interact with thyroid, blood pressure, or immunosuppressant drugs. Probiotics are generally well-tolerated alongside most medications but should be taken 2 hours apart from antibiotics. Your doctor can review the full ingredient list — we publish every single one on the label.

Our Probiotic Formula uses delayed-release capsules with a patented acid-resistant coating. This protects the live cultures from stomach acid so they reach your intestines intact — where they actually do their job. The strains we use are shelf-stable, meaning they don’t require refrigeration. They’re lyophilized (freeze-dried) and reactivate when they hit moisture in your gut.

We guarantee 40 billion CFU at time of manufacture and overcount by 20% to ensure potency through the expiration date. No refrigeration theater. No “keep frozen” fine print. They survive your shelf, your stomach acid, and your skepticism.

No. Absolutely not. The Shroom Complex contains medicinal mushrooms only — zero psilocybin, zero psychoactive compounds. Here’s what’s in it:
Lion’s Mane — cognitive function, nerve growth factor support.
Reishi — immune modulation, stress adaptation, gut lining support.
Chaga — antioxidant powerhouse, digestive inflammation support.
Turkey Tail — prebiotic polysaccharides that feed beneficial gut bacteria.
Cordyceps — energy metabolism, oxygen utilization.

These are functional mushrooms backed by decades of clinical research. The only trip you’re taking is to better gut health.

We strongly recommend consulting your OB-GYN or midwife before taking any LeanScience products during pregnancy or while breastfeeding. While our ingredients are generally recognized as safe for the general adult population, pregnancy and nursing alter your physiology in ways that change how supplements interact with your body. Some ingredients — particularly Ashwagandha and certain mushroom extracts — lack sufficient safety data for pregnant or lactating women. Don’t guess. Ask your doctor.

The gut-brain axis is the bidirectional communication network between your gastrointestinal tract and your central nervous system. Your gut contains over 500 million neurons and produces roughly 90% of your body’s serotonin. It’s not a metaphor — your gut literally talks to your brain via the vagus nerve, immune signaling molecules, and microbial metabolites.

When your gut microbiome is compromised, the signal degrades. Brain fog, mood instability, poor sleep, and anxiety can all trace back to dysbiosis. The LeanScience system addresses this axis from multiple angles: probiotics restore microbial balance, prebiotics sustain it, Ashwagandha modulates the stress response, and the Shroom Complex (particularly Lion’s Mane) supports neural signaling. Fix the gut, clear the head.

Directly and measurably. Chronic stress elevates cortisol, which does three things to your gut: (1) increases intestinal permeability (“leaky gut”), allowing partially digested proteins and bacterial toxins into your bloodstream; (2) shifts your microbiome composition toward inflammatory species; and (3) slows gastric motility, leading to bloating, constipation, and nutrient malabsorption.

This is why the LeanScience protocol includes Ashwagandha — a clinically validated adaptogen shown to reduce serum cortisol by up to 30% in controlled trials. You can’t fix your gut while your stress hormones are actively destroying it. Address both or address neither.
