A Digestive Supplement for Everyday Support

Every day, your digestive system handles far more than you might realise – breaking down food, absorbing nutrients, getting rid of waste and helping maintain overall balance in your body. When this system is supported, you tend to feel lighter, more comfortable and better able to go about your day.

Supplements like AG1 are designed to complement your daily habits by providing friendly bacteria, and supporting normal digestion – all in one scoop.⁷

Why Your Digestion Matters

When digestion feels smooth, you often feel it everywhere else.

When digestion is smooth, you think more clearly, move more comfortably and experience more predictable energy. When things feel “off,” discomfort in the gut can influence mood, appetite and motivation.

Your digestive system is one of the most dynamic environments in your body. It’s home to trillions of microorganisms, kilometres of intestinal lining and a vast network of nerves that communicate directly with your brain. This system works every minute to break down food, absorb nutrients and maintain internal balance – all while responding to stress, diet, sleep and movement.

Supporting digestion isn’t only about avoiding discomfort – it’s about giving your body a strong foundation for holistic well-being. Nourishing your gut helps everything downstream work more easily.

The Building Blocks of Good Digestion

Your digestive system does a remarkable amount of work every single day – and it functions best with supportive habits and consistent nourishment.

Nutrition

Digestive health depends on multiple layers working together. Calcium supports the normal function of digestive enzymes – the tiny biological tools that help break down nutrients. Vitamin A, biotin and more play a role in maintaining normal mucous membranes, which form part of the protective lining of the digestive tract.

Alongside these nutrients, foods rich in fibre and fermented foods – where diverse bacterial cultures are present – help create an environment in the gut where natural digestive processes can unfold more comfortably and consistently.

Movement

Movement acts as a natural stimulator for the digestive tract. When you walk, stretch or move regularly throughout the day, your digestive system receives mechanical cues that help support motility – the coordinated contractions that keep everything progressing through the gut.

Sleep & Stress Regulation

Your gut has its own nervous system, often called the “second brain.” It communicates constantly with your central nervous system through chemical messengers and nerve pathways. When stress is high or sleep is inconsistent, this communication shifts – which is why digestion can feel more sensitive during stressful periods or after short nights.

Supporting your nervous system often supports your digestion too.

How Your Digestive System Works

A closer look at the digestive process reveals just how coordinated and intelligent this system is – and what it needs to function properly.

Digestion begins before you even swallow – with enzymes in your saliva starting the process. As food passes through the stomach and small intestine, additional enzymes break nutrients into smaller components your body can absorb.

Why this stage matters

Enzymes are essential for efficient digestion, and calcium supports their normal function.⁷

What you can do

Eat mindfully, chew thoroughly and aim for meals that provide a variety of nutrients to support these reactions.

Your gut lining is only a single cell layer thick, yet it manages an enormous task: deciding what enters your bloodstream and what stays out. This lining is supported by a protective mucous layer that helps transport vital substances.

Why this stage matters

Vitamin A, biotin, riboflavin and niacin contribute to the maintenance of normal mucous membranes – a key part of this protective environment.⁷

What you can do

Support your body with steady nutrition, hydration and habits that help regulate stress.

The gut microbiome is a dynamic ecosystem that interacts with almost everything you consume. Nutritional experts agree that fibre-rich foods and bacterial cultures contribute to a more diverse, adaptable environment within the gut.

Why this stage matters

A balanced microbiome helps keep digestive processes running smoothly and supports your gut’s resilience to daily changes.

What you can do

Include fibre-rich foods, fermented foods and consistent eating patterns.

Your digestive system relies on rhythmic muscular waves to move food through. This movement – called peristalsis – is influenced by hydration, movement, meal timing and the nervous system.

Why this stage matters

Steady, comfortable digestion depends on this natural rhythm.

What you can do

Stay active, prioritise hydration and build eating routines that work for your body.

Nutrients That Support Your Digestive System
AG1 includes nutrients that support normal digestion – every day.
CALCIUM
Calcium supports the normal function of digestive enzymes that break food down into forms your body can use. These enzymes help catalyse the reactions that release nutrients from the food you eat.⁷
B VITAMINS
Biotin, riboflavin and niacin support the maintenance of normal mucous membranes – including those in the digestive tract. Intact mucous membranes help maintain the integrity of the gut lining, contributing to digestive comfort by helping the nutrient flow.⁷
PLUS: FIBRE
Despite not currently carrying an approved health claim, decades of scientific research highlight fibre’s important role in everyday digestive routines. It adds bulk to the diet, supports natural movement through the gut and helps create conditions that contribute to digestive comfort. Including fibre regularly can help your body maintain a rhythm that feels balanced and predictable.
PLUS: GUT BACTERIA
Bacterial cultures are not yet backed by authorised health claims, which is why we do not attribute specific physiological effects to them. However, the scientific community continues to explore how the trillions of microorganisms in the gut interact with diet, stress, lifestyle and digestive balance and resilience.
