Photobiomodulation for Digestive Health and Microbiome

What You’ll Learn

1. How simple daily habits like diet, hydration, sleep, and movement can make a big impact on your digestive health.
2. Why red light therapy may help reduce gut inflammation and support a healthier microbiome.
3. When it’s time to see a healthcare professional for lasting gut health improvements.

We’re finally finding out just how much gut health means to our overall well-being. Scientists are looking closely at how our gut microbiomes play important parts in digestion and immune function, as well as how it affects our brains. They’re also looking closely at how red light therapy can transform your gut health and overall digestive wellness. 

If you’re struggling with bloating, discomfort, and irregular digestion, you’re not alone! Let’s look at what the research says about red light therapy treatment and its effectiveness on gut health, and discover five ways you can get better digestion from red light therapy.  

Your gut health matters more than you think! 

Not only does your gut health matter more than you think, but it may be a main driver behind how you think. Some scientists are now referring to our guts as our “second brain,” based on how the diverse ecosystem of microorganisms in our digestive tract can affect everything from your mood to your immune system. 

We’re finding out that something like 90% of our body’s serotonin, that chemical that is called the “happiness hormone,” is produced in our guts! So when we have poor gut health, we have lower mental well-being. 

When things go wrong in your gut, this can trigger a kind of domino effect in your body that you never would have thought would be connected to digestion. Maybe you have brain fog and fatigue. Maybe it’s anxiety or mood swings. You’ll also find evidence that an out-of-whack gut microbiome can correspond with depression. The lesson here is that our digestive health likely plays a huge role in our mental health. 

But wait, there’s more! Skin problems and chronic inflammation, and chronic pain may also be linked in some ways to gut health. 

What all of this means is that it’s very much worthwhile to pay attention to what’s happening in our guts and to do whatever we can to keep our gut microbiomes flourishing and happy. When our gut is happy, we’re happy!  

What is red light therapy?

Red light therapy harnesses the power of red and near-infrared light to penetrate deep into the skin, stimulating cellular activity and enhancing overall function. By energizing cells and optimizing mitochondrial function, this therapy helps regulate the body’s stress response and reduces inflammation at a systemic level. Unlike other wellness treatments, red light therapy works at the cellular level, promoting natural healing and resilience without invasive procedures or pharmaceuticals.

While commonly associated with muscle recovery, skin rejuvenation, and pain relief, red light therapy also plays a crucial role in gut health. We just learned that having a healthy gut is essential, and red light therapy supports this by improving cellular function and accelerating tissue repair. By strengthening the gut lining and reducing inflammation, it may help mitigate issues like leaky gut, bloating, and discomfort while promoting a balanced microbiome.

Incorporating red light therapy into your wellness routine can be a game-changer for both physical performance and long-term health. Whether you’re looking to recover faster, reduce inflammation, or support gut balance, this innovative therapy offers a science-backed approach to optimizing your body's natural healing abilities.

How does red light therapy work for gut and digestive health?

Let’s start at the beginning and make it super simple. Your body, as you know, is made up of cells. Inside those cells are things called mitochondria. These create energy to get your body to do everything from running a marathon to thinking clearly. 

Red light therapy targets the mitochondria and gives them a boost. When you do a red light therapy session, your mitochondria spring into action, helping cells grow and repair themselves faster. 

How does this translate to gut health? Your gut has millions of cells that are working hard to break down food, absorb nutrients, and keep out anything that might affect you adversely. When those cells have more energy, they do a way better job. That means a stronger gut lining, less irritation, and protection against problems like “leaky gut,” where what you’re trying to digest gets through your intestines. 

It’s as simple as that! 

Five ways that red light therapy helps your digestive system

1. Reduces inflammation at the source

When you have an inflamed gut, everything else in your system starts to suffer. Red light therapy steps in by reducing gut inflammation at the source. By stimulating anti-inflammatory cytokines (chemical messengers that tell cells how to behave), your immune system starts to get the message that it needs to reduce inflammation. 

This is great for people who suffer from conditions like IBS, IBD, and even Crohn’s disease. 

Red light therapy has proven effective in reducing gut inflammation by stimulating the production of anti-inflammatory cytokines, crucial proteins that regulate the immune system and reduce swelling. This remarkable solution holds incredible potential to bring relief to individuals fighting conditions like IBS and IBD.

2. Balances your microbiome for better digestion

Inside your gut are trillions of microorganisms that help you to digest food. They also produce vitamins and protect against harmful pathogens. Just like any community, when this one is working poorly, negativity follows. In this case, that negativity presents as digestive issues. 

What science has found out recently is that red light therapy might help the good bacteria community in your gut to grow and thrive. Scientists experimented by aiming red light at the stomachs of animals, and what they found out was amazing! The healthy bacteria in the gut actually started growing more. Because these little guys are responsible for keeping your digestion running smoothly and your immune system strong, this would likely make one’s entire body feel better. 

What we don’t know yet is why red light has this effect, but researchers have solid ideas about it. It could be because red light helps reduce inflammation, or maybe because it boosts energy in gut cells, or even both. A few things are likely working together to create this gut-friendly magic.

The bottom line is that red light therapy sessions aimed at your gut might be a gentle, natural way to help your gut bacteria stay healthy and balanced. Here at Rouge, the G4 Nano panel is ideal for targeted treatments. 

3. Helps you digest better with improved collagen production

Collagen is an incredibly important aspect of a healthy body. It’s that special protein that keeps your body strong and moving in the right direction. You’ll find collagen at work in your skin, your joints, and even your gut. 

Red light therapy has been shown to help your body increase its collagen production levels. This is great news for the guy, as it is, essentially, the glue holding everything together. Inside your body, there's something called the extracellular matrix. 

Think of it like the scaffolding that keeps all your cells in place. Collagen is a big part of that scaffolding. If that structure gets weak or damaged, it can cause all sorts of health problems.

Red light therapy sessions will give your cells a boost and help them build stronger collagen. Now your “scaffolding” stays in place and your guy stays happy. 

Another positive thing we’ve learned is that healthy collagen and a strong gut lining help support your gut bacteria. With this comes more butyrate, a fatty acid that is important in keeping your gut calm and your digestive system running smoothly. 

Scientists are finding out more all the time, but what we know at this point is that red light therapy is definitely worth looking into for better digestion and overall gut health. 

4. Strengthens your gut barrier

We mentioned “leaky gut” earlier in this post. This is a condition that happens when your intestinal lining becomes compromised, allowing partially digested food particles and toxins to leak into your bloodstream. This triggers inflammation and immune reactions throughout your body.

Research found that photobiomodulation, aka Red Light Therapy, actually increased the production of proteins that maintain the formation of your gut barrier and help to repair and reinforce it at the cellular level. Fewer toxins leaking into your bloodstream means less inflammation and stronger immune function. A positive result all around! 

5. Enhances circulation to your digestive organs

If you’re going to have a healthy digestive system, you’re going to need to have proper blood flow. One of the ways that red light therapy helps with this is by increasing nitric oxide production. This is important, as it’s a molecule that helps to dilate blood vessels and improve circulation.

When you have better blood flow, you have more oxygen and nutrients being delivered to your digestive organs. The result is that the increased blood flow means a better functioning digestive system that can support the healing processes throughout your body. 

How to use red light therapy for better digestion

Ready to try red light therapy to help your digestion? What is important to remember is that red light therapy should be used in addition to other therapies, not as a replacement for anything that your doctor already recommends. It’s important to work with your health professional to ensure you’re getting proper care and treatment for all of your potential digestive health issues. 

Remember that not everyone’s body is the same. What works great for someone else might feel different for you. So, pay attention to how you feel, take your time, and choose what fits with your goals and how you want to take care of yourself.

You can boost your gut health naturally

Want to help your digestion work better? It starts with what you eat. Try to pack your meals with colourful, fibre-rich fruits and veggies, whole grains, and don’t forget to get that good, good bacteria from yogurt. Herbs like ginger, turmeric, cinnamon, and rosemary are also great for keeping your belly happy.

Don’t forget to stay hydrated, get enough sleep, keep your body moving, and manage stress the best you can. This all will help your digestive system do its job. Think of it like giving your gut a little daily support team.

While red light therapy isn’t a cure-all, it shows real promise. By helping your cells work better and calming inflammation, it could make a big difference for people dealing with gut troubles. And because it can also improve sleep, reduce stress, and support your immune system, it might help your digestive health in more ways than one.

And don’t forget to talk to your health professional, as well. It’s the first step to having a healthy gut!
