Hero ingredient
The 20-Strain Probiotic Blend
A broad-spectrum bacterial blend of 20 strains at 20 billion CFU, designed to restore and diversify a depleted gut microbiome with one capsule daily.
Most probiotic supplements rely on one or two strains in isolation.Complete Biotics takes a different approach: 20 complementary bacterial species from the Lactobacillus, Bifidobacterium, Pediococcus, Lactococcus, and Streptococcus families, each selected for its distinct role in a healthy, diverse gut ecosystem.
20 Distinct Strains
Covers a broad range of gut microbiome niches in one formula
20 Billion CFU Daily
Potency level meaningful enough to reach and influence gut flora
Prebiotic Paired
Inulin from chicory root feeds the strains once they arrive
One Capsule Format
No powder, no sachets, no complicated dosing schedule
The Mechanism
The Gut Reset Loop: four steps to a rebalanced microbiome
Arrive
20 bacterial strains and 20 billion CFU reach the gut in a single capsule taken with water.
Fuel
Chicory root inulin acts as a prebiotic, feeding newly arrived beneficial bacteria so they can establish and multiply.
Colonise
Diverse Lactobacillus and Bifidobacterium species crowd out disruptive microbes and begin restoring balance across the gut lining.
Sustain
A healthier microbial ecosystem supports digestion, immune signalling, serotonin pathways, and nutrient absorption over time.
The result: steadier digestion, less bloating, a stronger immune barrier, and a gut-brain axis that can support mood and energy — without overhauling your lifestyle.
The Science
The Disrupted Gut Loop: four reasons imbalance persists
Gut imbalance rarely comes from one cause. It builds from four overlapping breakdowns — and Complete Biotics is designed to address each of them directly.
01
Low Microbial Diversity
Most modern diets and antibiotic use reduce strain variety in the gut, leaving the microbiome too narrow to defend itself or regulate digestion properly.
02
Insufficient Probiotic Dose
Many supplements provide too few CFU to meaningfully shift gut flora. Low-potency products are cleared before they establish a foothold.
03
No Prebiotic Support
Probiotics without a fuel source struggle to colonise. Without inulin or similar fibres, new bacteria arrive but cannot sustain their numbers.
04
Gut-Brain Axis Disruption
An imbalanced microbiome reduces serotonin precursor production and increases gut permeability, contributing to low mood, fatigue, and poor immune regulation.
Key ingredients
Key ingredients
Complete Biotics combines a 20-strain bacterial blend at 20 billion CFU with chicory root inulin as a prebiotic companion. Together, these ingredients target microbiome diversity, digestive comfort, immune defence, and gut-brain communication in a single daily capsule.

90 mg
Inulin from Chicory Root
Prebiotic fibre support
A natural prebiotic fibre from chicory root (Cichorium intybus L.) that feeds beneficial gut bacteria and helps them establish and sustain their colonies after arrival in the gut.

Questions
Frequently asked questions
Complete Biotics delivers 20 bacterial strains at 20 billion CFU per capsule, alongside Inulin from chicory root as a prebiotic.The strains help restore microbial diversity in the gut, while inulin feeds and sustains them.Together they support a more balanced gut environment, healthier digestion, and a stronger gut barrier over time.
Complete Biotics contains 20 distinct bacterial strains including multiple Lactobacillus and Bifidobacterium species.A wider strain variety covers more ecological niches in the gut compared to single- or dual-strain products, helping support a broader, more resilient microbiome rather than just one function.
Probiotic results build gradually as bacterial strains establish themselves in the gut.Many users notice improvements in bloating and digestive comfort within 2–4 weeks of consistent daily use.Full microbiome rebalancing typically takes longer, so sustained use over a 30-day supply and beyond is recommended for best results.
Inulin is a natural prebiotic fibre derived from chicory root.It acts as food for beneficial bacteria, helping the 20 strains in Complete Biotics establish and multiply once they reach the gut.Without a prebiotic fuel source, probiotic strains can struggle to colonise effectively, so inulin is included to support them.
Complete Biotics is formulated to help restore overall microbial balance in the gut.A diverse and well-supported microbiome may help create an environment less hospitable to opportunistic organisms like candida.It is not a specific candida treatment, but it supports the gut conditions associated with a healthier internal balance.
Take one capsule daily with a full glass of water.It can be taken with or without food.For best results, take it at the same time each day, ideally in the morning, to build a consistent habit.Do not exceed the recommended daily dose of one capsule.Store in a cool, dry place below 25°C.
Complete Biotics is a food supplement designed for daily use.One 30-capsule pack provides a 30-day supply.It is not a substitute for a balanced diet or healthy lifestyle.If you are pregnant, breastfeeding, or taking medication, consult a healthcare professional before use.Keep out of reach of children.
A balanced and diverse gut microbiome plays an important role in immune regulation, since a large proportion of immune activity is associated with the gut.Complete Biotics supports gut flora balance through its 20-strain probiotic blend, which may in turn help support the body's natural immune defence over time.
This dietary supplement is essentially free from substances containing gluten.However, it's worth noting that Golden Tree Complete Biotics are not manufactured in a facility with an absolute 100% guarantee of no contact with gluten traces.Therefore, as a precaution, we recommend that individuals with celiac disease avoid this product due to their specific needs for extreme caution.However, for those with mild gluten sensitivities, there should be no unnecessary concerns.
