6 Natural Digestive and Gut Health Supplements

Why Digestive Health Matters

Our digestive system doesn’t just process food—it impacts virtually every aspect of our health. Poor gut health has been linked to many conditions, including bloating, irritable bowel syndrome (IBS), Candida overgrowth, leaky gut, and even chronic diseases like type 2 diabetes and inflammatory bowel disease (IBD).

By taking care of our gut, we create the foundation for better digestion, stronger immunity, and long-term wellness. A well-functioning digestive system is essential for overall health, vitality, and well-being.

Why our Gut Health Matters

A thriving gut microbiome is the foundation of our overall health. When it’s in harmony, digestion runs smoothly, immunity stays strong, and the body functions optimally. But when it’s out of balance, issues such as bloating, IBS, Candida overgrowth, inflammation, and even mood disorders can arise (Van Hul et al., 2024). Experts believe that many of our chronic health problems we have their origin inside our gut (Guinane et al., 2013).

Gut Microbiome: Why It’s Essential for Our Health

The gut microbiome is a vast and complex ecosystem, home to trillions of microorganisms—including beneficial bacteria, fungi, and viruses—that reside in the gastrointestinal (GI) tract (Thursby et al., 2017).

These invisible but mighty powerful microbes influence and shape virtually every aspect of our health, from digestion and immunity to our waistline, even our mental health well-being.

A well-balanced gut microbiome contributes to:

Efficient Digestion & Nutrient Absorption
Breaks down food, extracts essential vitamins and minerals, and aids in nutrient metabolism.
Waste & Toxin Elimination
Supports regular bowel movements, helps detoxify harmful substances, and prevents buildup of waste.
Immune System Regulation
Forms a protective barrier against harmful invaders, trains immune cells to recognise threats, and reduces inflammation.
Pathogen Defence
Competes with and suppresses harmful bacteria, fungi, viruses, and parasites to maintain a healthy microbial balance.
Mental Health & Mood Regulation
Produces neurotransmitters like serotonin and dopamine, directly linking gut health to brain function, mood stability, and cognitive performance.

Since our gut microbiome and the body work closely together, it’s not surprising that an imbalance in gut bacteria (called dysbiosis) is linked to many health issues, from digestive disorders to brain-related conditions (Guinane et al., 2013), (Schroeder et al., 2016).

Although the gut microbiome is naturally resilient, several factors can disrupt its delicate balance, leading to digestive discomfort, weakened immunity, and increased susceptibility to chronic health issues.

These include:

Poor Diet
High refined sugar, junk and ultra-processed foods, and low-fibre diets encourage the growth of harmful bacteria while starving beneficial microbes.
Chronic Stress
Alters gut motility, reduces beneficial bacteria, and increases gut inflammation (Madison et al., 2019).
Sedentary Lifestyles
Our high-tech lifestyles have made it easier for us to do less, and it’s proven to be bad for our gut function, especially our gut microbiome (Conlon et al., 2014).
Medications & Antibiotics
Antibiotics kill harmful and beneficial bacteria, causing microbiome imbalances (Patangia et al., 2022).
Toxins & Environmental Pollutants
Exposure to pesticide, heavy metals, and many chemicals negatively impacts gut flora (Ali et al., 2024).
Lack of Probiotic & Prebiotic Foods
Without adequate intake of fermented and prebiotic foods, fibre, and beneficial bacteria, our gut microbiome struggles to maintain balance, allowing disease to more easily develop (Aziz et al., 2024).

How We Can Best Support Our Digestive System?

A woman and a young girl are sitting at a table enjoying a meal together. The table is set with various dishes and a glass of red wine. They are smiling as they look at each other.

By supporting gut health through healthy diet, lifestyle, and targeted supplementation, we can promote a balanced microbiome and significantly improve our overall physical and mental well-being.

A healthy gut starts with a diverse diet rich in fibre, whole foods that are nutrient-dense, and probiotic-rich foods. There is little point consuming foods hat have little nutritional value while taking supplements. But sometimes, even a healthy diet alone isn’t enough, especially when somebody has Candida overgrowth, and specialised gut health supplements can provide extra support.

The right digestive supplements can:

Improve food breakdown and nutrient absorption
Support regular and comfortable digestion
Help maintain a healthy balance of gut bacteria
Aid bowel and liver detoxification and reduce bloating
Reduce Candida overgrowth and SIBO symptoms
Soothe digestive discomfort and inflammation

Let’s now explore some of the best supplements for gut health.

The Best Natural Supplements for Gut and Digestive Health

1 – Digestive Enzymes: Improve Nutrient Absorption

Digestive enzymes help break down food into smaller nutrients that the body can absorb. They are especially useful for those with enzyme deficiencies, bloating, or food intolerances.

Digestive enzymes are proteins that act as biological catalysts to break down food into smaller, absorbable nutrients. These enzymes are essential for proper digestion, ensuring that carbohydrates, proteins, fats, and other nutrients can be efficiently absorbed into the bloodstream and utilised by the body. Without enzymes, essential nutrients remain locked within food and cannot be properly absorbed.

Most digestive enzymes function optimally in the highly acidic environment of the stomach (pH 2–4). While our body produces its own digestive enzymes, many factors—like Candida overgrowth, SIBO, IBS, aging, stress, poor diet, or illness—can impair enzyme production, leading to issues like bloating, mal-absorption, and gut dysbiosis.

Common digestive enzymes include:

Amylase – Helps digest carbohydrates
Lactase – Helps digest lactose (for those with lactose intolerance)
Lipase – Supports fat digestion
Protease – Breaks down proteins into amino acids

Taking a premium digestive enzyme supplement with meals can enhance digestion, reduce bloating, and improve nutrient absorption.

When it comes to an effective digestive enzyme supplement, we’ve made it easy by combining all the key carbohydrate, protein and fat digesting enzymes into one capsule.

Antimicrobial supplements can be taken as stand-alone dietary supplements, but will be found more effective when taken as part of a well-structured Candida Cleanse Program that also includes digestive enzymes and probiotics.

Digestive Enzymes Take-Home

Probiotics are live beneficial bacteria that restore and maintain gut microbiome balance.

Each probiotic strain has unique effects, and their benefits depend on the genus, species, and strain used. Some probiotic strains are particularly effective for digestive health, while others support immune health, metabolic health, or vaginal flora (NIH 2024).

Probiotics are classified by their strain, with the 7 types of groups most commonly used in dietary (probiotic) supplements and fermented foods listed. The following genera contain multiple species that have been extensively researched for their health benefits.

The main groups of probiotics are:

Bacillus
Bifidobacterium
Enterococcus
Escherichia
Lactobacillus
Saccharomyces
Streptococcus

Understanding the different types of probiotics and their benefits can help in choosing the right strains for specific health concerns. We’ve made it easy by combining the best probiotic strains in a capsule that resists stomach acid, ensuring the bacteria get to where they need to be, in a lower acid environment further down.

A high-quality probiotic supplement can be beneficial for many reasons, for example after taking antibiotics, during travel, or for managing digestive issues like Candida overgrowth, SIBO, irritable bowel syndrome, and IBD cases, such as ulcerative colitis.
