Customers Already Buy Microbiome Plus+ for Four Different Reasons
Microbiome Plus+ positions itself as a clinically studied heart and gut health probiotic. Its customers, however, describe bloating relief, cholesterol management, research-backed supplement buying, and post-COVID gut recovery just as often as they mention the brand's clinical positioning.
The review data reveals a clear pattern: digestive health and bloating relief dominate buyer language, with over 200 signals across bloating, digestion, stomach, and gas mentions. Yet the brand's website leads with clinical studies and heart health. Meanwhile, 145+ reviews reference heart health, cholesterol, and LDL specifically, confirming that market is real but only partially activated. A smaller but highly engaged segment found the product through clinical research, podcasts, and doctor referrals. And an emerging group of post-COVID and functional medicine patients are discovering the product through practitioner networks.
This report identifies four markets where Microbiome Plus+ already competes. Three of those markets represent growth that requires no new formulations and no additional SKUs. The customers are already buying. The marketing just needs to catch up.
What the Brand Says vs. What the Product Does
The gap between how Microbiome Plus+ describes itself and what its customers actually experience is significant. The brand says "clinically studied heart health probiotic." The customer base says "it fixed my bloating." That gap is where the growth is.
Four Markets, One Brand
This is the dominant buyer motivation in the review data. Over half of all reviewers describe digestive improvement as their primary experience. Bloating alone appears in 102 reviews, making it the single most mentioned benefit after the generic product terms "probiotic" and "prebiotic." These buyers found Microbiome Plus+ searching for gut relief, not heart health. The brand's clinical positioning around cholesterol and LDL is largely invisible to this audience.

What They Say
"Before taking the prebiotic and the probiotic there were many foods I could not eat. I'm now enjoying food like I did when I was young. It has almost completely stopped all bloating."
Verified Buyer, Loox Review"I have been taking it for a few weeks and I have noticed an improvement in gas and bloating."
Verified Buyer, Loox Review"Great pre and probiotics! After struggling with a slow digestive process for my entire adulthood, I'm finally feeling so much better."
Verified Buyer, Loox ReviewThis is the market Microbiome Plus+ was built for, and the clinical data is genuinely differentiated. Seven peer-reviewed studies showing 11.64% LDL reduction and 25.5% Vitamin D increase give this brand a claim no competitor in the probiotic space can match. Reviewers in this segment specifically mention wanting to avoid statins, getting recommendations from healthcare providers, and tracking their lipid panels. The opportunity is not awareness of the product. It is that the brand's marketing does not separate this audience from the general supplement buyer. Heart health buyers need different landing pages, different ad creative, and different proof points than bloating buyers.

What They Say
"I have used Microbiome Plus now for 3 months after researching how to naturally improve my lipids. My total cholesterol and LDL have been slowly elevating."
Verified Buyer, Loox Review"My nurse practitioner suggested this to help lower my cholesterol."
Verified Buyer, Loox Review"So far I've been happy with the supplement. Nice packaging. Easy to take. I've been able to maintain a healthy LDL and ApoB level without drugs."
Verified Buyer, Trustpilot ReviewA distinct segment of buyers found Microbiome Plus+ not through ads or bloating searches, but through clinical literature, podcasts, and functional medicine practitioners. These reviewers mention Dr. William Davis by name, reference specific research papers, and discuss strain specificity (NCIMB 30242) in their reviews. They are the most informed buyers in the probiotic category and the hardest to acquire, but they have the highest conviction and the lowest churn. They do not need to be sold on probiotics. They need to be sold on this specific strain.

What They Say
"Have used this product for over a year after reading the research and listening to Podcasts recommending it. Good for the gut and the heart."
Verified Buyer, Loox Review"I've done my research regarding the importance of L-Reuteri to improve and maintain immune health."
Verified Buyer, Loox Review"Dr. William Davis recommends it and I am seeking a healthy digestive track."
Verified Buyer, Loox ReviewA small but highly specific group of buyers found Microbiome Plus+ while recovering from COVID-related gut issues or through functional medicine practitioners treating complex digestive conditions. These reviewers mention SIBO recovery, long COVID GI symptoms, and referrals from functional doctors. The "no histamine release" property of L. Reuteri NCIMB 30242 is uniquely important to this audience, as many post-COVID patients react poorly to histamine-producing probiotic strains. This is a niche market, but it is growing, underserved, and the buyers are highly motivated.

Verified Buyer, Trustpilot ReviewSide by Side
| Market | Current Presence | Review Signals | Market Size | Top Angle |
|---|---|---|---|---|
| Digestive Health & Bloating Relief | Fully served | 200+ signals (49%) | Current | "I Can Finally Eat Without the Bloat" |
| Heart Health & Cholesterol | Partially served | 145+ signals (36%) | Large | "11.64% LDL Reduction. 7 Studies." |
| Science-Driven Buyers | Untapped | 30+ signals (7%) | Medium | "The Strain Matters: NCIMB 30242" |
| Post-COVID & Functional Medicine | Untapped | 13+ signals (3%) | Niche | "A Probiotic That Won't Make It Worse" |
The heart health and cholesterol market alone represents 36% of review signals, yet the brand's current ad creative and landing pages do not isolate this audience with dedicated messaging. These buyers are searching for "lower cholesterol naturally" and "statin alternatives," not "best probiotic." Building market-specific funnels for just this one segment could significantly expand the addressable audience without any product changes.
Three Moves That Require Zero Product Changes
Launch Cholesterol-Focused Ad Creative
Create a dedicated ad funnel targeting "lower cholesterol naturally" and "statin alternative" keywords and interests. Lead with the clinical data: 11.64% LDL reduction, 7 peer-reviewed studies, FDA GRAS status. This audience does not care about bloating or general gut health. They care about their lipid panel. The statin-alternative market is massive (over 40 million Americans take statins) and no probiotic brand currently owns this positioning with real clinical data.
Build a "Gut Health Protocol" Landing Page
Create a dedicated page showing the complete digestive health system: L. Reuteri probiotic + prebiotic fiber + digestive enzymes. Position it as a protocol, not a single product. Optimize for "best probiotic for bloating" and "gut health supplement stack." The review data shows that buyers who purchase the probiotic and prebiotic together report the strongest results. A single protocol-focused landing page with bundle pricing would capture the high-intent digestive health searcher directly.
Create Doctor and Podcast Referral Content
Build a clinical resources page with study summaries, strain-specific data sheets, and shareable content designed for healthcare practitioners and podcast hosts. Buyers who arrive through a doctor or podcast recommendation have the highest conviction and lowest return rates. The 7 clinical studies are an underutilized asset. Making them accessible and shareable turns every functional medicine practitioner into a potential distribution channel.
How to Validate These Discoveries
Pick one market to test first. The heart health and cholesterol market has the strongest clinical differentiation and the clearest evidence. Reviewers describe measurable LDL improvements, healthcare provider referrals, and a specific desire to avoid statins. The addressable market is massive and no probiotic brand currently owns this positioning with credible clinical data.
Build one landing page with market-specific positioning. Same product, different story. Run traffic to both pages (current general positioning vs. new "clinically proven cholesterol support") and compare conversion rates and AOV.
Test 3 ads per audience. Cholesterol buyers get "11.64% LDL reduction. 7 peer-reviewed studies. No statins." Bloating buyers get "The probiotic + prebiotic combo that stopped my bloating in two weeks." Science buyers get "NCIMB 30242: the most clinically studied probiotic strain for heart and gut health."
Measure which market converts most efficiently. Not just conversion rate, but CAC, AOV, and repeat rate. A market with lower conversion but higher AOV and repeat rate might be more valuable long-term.
What we did not include: This is third-party data (public product reviews via Loox and Trustpilot). With first-party data like purchase history, support tickets, and email engagement, we could tell you which of these audiences actually has the highest AOV, when they buy, what drives repeat purchases, what causes refunds (and which audiences refund most), and where spend is going to low-intent traffic.
