If you’ve ever wondered what’s really happening beneath the surface of your daily routine, your water bottle, food packaging, even the air you breathe, you might be surprised to learn that microplastics have quietly become unwelcome guests in our bodies. Research has revealed plastic particles in human blood, lungs, and even the digestive tract. It’s confronting, I know, and not exactly the kind of “house guest” you can politely ask to leave.

As a clinical nutritionist, I see growing concern about these invisible pollutants and their potential to interfere with gut balance. This is where I often turn to a gentle, physical approach: using food-grade diatomaceous earth and fulvic humic minerals to help the body naturally clear what it doesn’t need.

What exactly are microplastics doing in the gut?

Microplastics are tiny fragments, less than 5mm in size, that can lodge themselves in the digestive system. Think of them as microscopic gate-crashers at your gut’s dinner party, no one invited them, yet they turn up everywhere. While the science is still emerging, early studies suggest these particles can irritate the gut lining, increase intestinal permeability, and trigger oxidative stress and inflammation. They may also disrupt the delicate balance of your microbiome, reducing beneficial bacteria, altering short-chain fatty acid production, and potentially nudging you towards issues like bloating, altered bowel habits, and low-grade, body-wide inflammation over time.

Unless we live in a (microplastic) free bubble, we can’t completely avoid them, so the focus needs to shift from panic to practical action. So how we can help our body manage and move them out?  Rather than reaching for harsh detoxes or quick-fix cleanses, I love using simple, mineral-based “micro-cleaners” that support the gut’s own inbuilt housekeeping system.

This is where fossil shell flour, a natural form of amorphous silica, plays a beautiful role. Found in Love Your Gut Powder, it acts as a soft, physical sweep, brushing through the digestive tract, absorbing gases and impurities, and encouraging daily elimination. Unlike harsh cleanses or chemical detoxes, this mineral food supports rather than strains the system.

How does an Internal Plumber work?

A physical sweep (Just like and internal plumber) supports gut health by using natural minerals that mechanically cleanse without chemical reactions. It’s a little like using a soft exfoliant on your skin, only this one works on the inside with no loofah required. Love Your Gut Powder contains food-grade diatomaceous earth for humans, sourced in Australia, and is free of additives or harsh compounds.

Diatomaceous earth (DE), the key ingredient in Love Your Gut Powder, works through its unique microscopic honeycomb structure that carries a strong negative charge. This allows it to attract, bind, and sweep out positively charged toxins, including heavy metals, parasites, and environmental debris like microplastics, as it travels through the digestive tract. Unlike chemical detox methods, food-grade DE for humans loosens built-up plaque and impurities without harming the gut lining, gently encouraging their elimination while infusing the body with essential minerals like silica, calcium, and magnesium.

Pairing this with Fulvic Humic Concentrate deepens the process by nourishing your cells with trace minerals and natural carbon complexes, which help optimise nutrient absorption and cell energy. Together, they form a powerful duo for helping the gut defend, repair, and renew itself.

Fulvic Humic Concentrate also brings some clever science to the table too. A number of emerging studies suggest fulvic and humic acids can interact with tiny plastic particles—such as nanoplastics and polystyrene fragments—reducing their toxicity and helping to modulate the body’s stress response to them. These natural carbon complexes act a bit like protective “bodyguards,” gently binding microplastic particles, lowering their ability to damage cells, and supporting the pathways that escort them safely out of the body. In a world where plastics are everywhere, this quiet support adds up.

Together, they create a synergistic duo: DE physically removes the debris, while fulvic humic nourishes and protects, helping your body reclaim balance in a plastic-permeated world.

How to turn this into a simple ritual

Start your morning with a TBS of Love Your Gut Powder in water or blended into a smoothie. In the evening, add a few drops of Fulvic Humic Concentrate to your favourite drink. Small daily actions like this help your body keep its internal “filter” clear and functioning well.
