Gut Health: Why Your Digestion Affects Everything (And How to Fix It)

Reverse Ageing 0 comments

There's a reason the gut is called the 'second brain.' It contains over 100 million neurons, produces roughly 90% of your body's serotonin, and houses approximately 70% of your immune system.

What happens in your gut doesn't stay in your gut — it affects your mood, your energy, your skin, your weight, and your resilience to illness.

The State of Gut Health Today

Bloating after meals. Irregular bowel movements. Energy crashes in the afternoon. Skin that won't cooperate. Brain fog that comes and goes without explanation. These are all potential signs of a disrupted gut microbiome.

Modern life is hostile to this ecosystem. Antibiotic use, ultra-processed diets, chronic stress, low fibre intake, and even chlorinated water all deplete the diversity and population of beneficial gut bacteria.

How the Gut-Brain Connection Works

The gut and brain communicate constantly via the vagus nerve — a bidirectional communication highway. This is why anxiety causes stomach upset. It's also why gut inflammation can cause brain fog, low mood, and fatigue.

Probiotics: The Good Bacteria Your Gut Needs

Lactobacillus Acidophilus

One of the most studied probiotic strains. Supports the intestinal lining, produces lactic acid to inhibit harmful bacteria, and has been shown to reduce bloating and improve bowel regularity.

Lactobacillus Rhamnosus

Particularly well-researched for immune modulation, reducing gut permeability ('leaky gut'), and supporting recovery from antibiotic-associated diarrhoea.

Bifidobacterium Longum

Dominant in the large intestine. Breaks down dietary fibre, reduces gut inflammation, and has documented effects on anxiety and depression through the gut-brain axis.

Prebiotics: Feeding the Good Bacteria

Probiotics need fuel. Inulin is one of the most effective prebiotic fibres — naturally found in chicory root, garlic, and onions. Supplementing with inulin alongside probiotics dramatically improves their survival and colonisation in the gut.

Digestive Enzymes: When Food Doesn't Get Fully Processed

Digestive enzymes break food down into molecules small enough to be absorbed. As we age — and particularly under chronic stress — enzyme production naturally declines.

  • Amylase — breaks down carbohydrates
  • Lipase — breaks down fats
  • Protease — breaks down proteins

Reverse Ageing's Gut Health Pro combines all three: 4 billion CFU of clinically studied probiotic strains with Inulin Prebiotic Fibre, a Digestive Enzyme Blend, Ginger Root Extract, and Piperine for enhanced absorption.

Frequently Asked Questions

How long does it take probiotics to work?

Most people notice improvements in bloating and bowel regularity within 1–2 weeks. More significant changes to the microbiome typically develop over 4–8 weeks of consistent use.

What happens when I stop taking probiotics?

Probiotic bacteria are transient — they don't permanently colonise the gut without continued supplementation and a diet that supports them.

Your Gut Is Trying to Tell You Something

Bloating, fatigue, skin issues, mood swings, and a weakened immune system are not separate problems. They may all trace back to the same source.
