Insights: Understanding Internal Hygiene™ & The Science of Freshness: Blog + Research Studies

Where science meets everyday wellness from the inside out

Welcome to Insights: where science meets everyday wellness. We believe understanding why something works is just as important as knowing that it works.


Here, we break down the research behind Internal Hygiene™, explore the gut-odor connection, and share what we're learning about natural wellness and body odor management. No hype. No shortcuts. Just honest, science-backed content designed to help you make informed choices about your body.

Education Over Persuasion

Most supplement companies stop at "just trust us." We don't. We believe you deserve to understand what you're putting in your body... and why it works. That's why we publish our research, break down ingredients, and explore the science behind natural wellness.


The more you know, the better choices you make. And better choices lead to better results.
When you understand the Gut-Odor Axis: how volatile compounds form in your gut, circulate through your bloodstream, and exit through your skin and breath, you understand REFRESH stops being "just another supplement." It becomes the obvious, logical solution to a problem you finally understand.
 

This is Internal Hygiene™ education. This is how we build trust.

What Is Internal Hygiene™? The Missing Third Pillar of Personal Care

You practice oral hygiene (brushing teeth). You practice topical hygiene (showering, deodorant). But what about the odor your body produces before it reaches your skin?


Internal Hygiene™ is the daily practice of managing odor-causing compounds at their source: from your gut. That's where your microbiome produces volatile sulfur compounds (VSCs), trimethylamine (TMA), and other odor precursors that circulate systemically and exit through pores, breath, and sweat.
 

This article explores:

- Why traditional hygiene only addresses surface symptoms
- The science of the Gut-Odor Axis (gut → bloodstream → skin/breath)
- How Internal Hygiene™ works alongside, not instead of, your existing routine
- The difference between masking and managing odor at the source

Understanding Your Internal Odor Complex and the Gut-Odor Axis: The Modifiable Factor in Body Odor

Your Internal Odor Load™ is the total metabolic burden of odor-causing compounds your body produces daily. Think of it as the "volume dial" for body odor.


High Internal Odor Complex = Gut produces excess volatile compounds → Overwhelms topical hygiene → You smell "off" within hours, no matter how much you scrub
Low Internal Odor Complex = Gut produces minimal volatile compounds → Topical hygiene is highly effective → Freshness lasts all day
 

This article breaks down:

- What increases your Internal Odor Complex (diet, stress, dysbiosis, genetics)
- How to measure your baseline (self-assessment + lifestyle factors)
- Evidence-based strategies to lower your load (Internal Hygiene™, probiotics, dietary adjustments)
- Why some people "just smell worse" (it's metabolic, not moral)

How Odor Really Begins (And Why Topicals Can't Fix It)

Most people think body odor starts on the skin. Science says otherwise.


The Gut-Freshness Axis™ is the biological pathway connecting your digestive system to your skin, breath, and sweat glands. 

 

Here's the journey:
Step 1: Odor Formation (The Gut)
Your microbiome produces hydrogen sulfide (H₂S), trimethylamine (TMA), methanethiol, indole, and volatile sulfur compounds during normal digestion—especially when breaking down protein and sulfur-rich foods.


Step 2: Systemic Circulation (The Bloodstream)
These volatile compounds cross the intestinal barrier and enter your bloodstream, traveling throughout your body.


Step 3: Odor Excretion (The Exit Routes)
Your body eliminates these compounds through sweat glands, pores, and breath—creating persistent body odor that no amount of scrubbing can eliminate.

The bacterial species that produce odor compounds (Desulfovibrio, Clostridium, Corynebacterium). The chemistry of why you smell (H₂S, TMA, VSCs explained). How "leaky gut" worsens systemic odor
