Is Your Skin Reacting to Your Gut?
Practical Steps to Try First
A short, practical companion to the gut-skin science, built around what to actually do
You've bought the 'miracle' cleanser. Switched to 'clean' skincare. Tried cutting sugar, dairy and gluten. And your skin still flares.
If that's you, here's the short version: you're not doing anything wrong, you're just looking in the wrong place. For a lot of clients, the real issue isn't on their face, it's in their gut. For the full explanation of why, see The Gut-Skin Axis: How your Diet and Digestive Health are Affecting your Skin. This piece is the practical follow-up: what to actually put on your plate and change in your routine.

The 'Glow Bowl': my go-to gut-skin lunch
This is a simple lunch worth building into a regular rotation:
Glow Bowl: grilled salmon, quinoa, avocado, sauerkraut (if tolerated), leafy greens, and a lemon-tahini dressing.
It delivers omega-3s, fibre, probiotics, antioxidants and healthy fats in one bowl, everything the gut-skin axis actually runs on. Sauerkraut is worth introducing gradually if you're not used to fermented foods, a couple of tablespoons is plenty to start.

Stress, sleep and skin
Food matters, but it isn't everything. Stress increases gut permeability, poor sleep blocks repair, and constant overworking exhausts the immune system. Alongside diet, it's worth paying attention to nervous system regulation, aiming for 7 to 9 hours of sleep, gentle movement, journaling or a 'mind dump,' and eating without rushing or scrolling. A calmer body supports a calmer gut, which tends to show up as calmer skin.
Collagen and skin repair
Collagen provides amino acids that support gut lining repair, immune balance and skin elasticity, the elasticity benefit in particular has reasonable evidence behind it from clinical trials on oral collagen supplementation. Some clients choose supplements such as Ancient & Brave alongside dietary improvements for added support. Get your exclusive discount on Ancient & Brave products here. Supplements never replace food, but they can support recovery alongside it.
When to look beyond diet
If your skin condition is cyclical, stress-related, resistant to creams, or better one week and worse the next, diet changes alone may not be enough. That's usually the point to look at what's actually driving things rather than continuing to adjust food in isolation, the gut-skin axis article covers testing options and the evidence behind them in full.
FAQs
Is the Glow Bowl suitable if I have a lot of food intolerances? It's easy to adapt, swap salmon for another protein, skip the sauerkraut if fermented foods aren't tolerated yet, and adjust the dressing. The principle (protein, fibre, healthy fats, a fermented food if tolerated) matters more than the exact recipe.
How much does stress really affect skin, compared to diet? Both matter, and they interact, chronic stress can undo some of the benefit of a good diet by increasing gut permeability and inflammation. Addressing both together tends to work better than focusing on food alone.
Do I need to take collagen for my skin to improve? No, it's optional support rather than a requirement. Diet, sleep and stress management do most of the work; collagen can be a helpful addition on top of that foundation.
How quickly might I notice a difference from these changes? This varies by person and by what's driving the skin issue. Many people notice some difference within a few weeks of consistent changes, though deeper gut-driven skin conditions often take longer and may benefit from the testing covered in the main gut-skin axis article.
