One of the questions I’m asked most often about DermaGut+ is: “I was expecting it to help my digestion, so why do I feel more sluggish?” It’s a great question, and one I want to answer properly because the science behind it is genuinely fascinating, and understanding it will completely change how you approach your supplement routine.
How Does Sunfiber Actually Work?
Most people assume fibre works like a broom — sweeping things through the gut. But PHGG/Partially Hydrolysed Guar Gum, the hero prebiotic fibre in DermaGut+, works through an entirely different mechanism: fermentation. Rather than physically bulking your stool, it feeds your beneficial gut bacteria, which in turn produce short-chain fatty acids (SCFAs). These are powerful metabolites that stimulate gut motility, reduce intestinal inflammation, and strengthen the gut-skin barrier. This is why DermaGut+ supports not just digestion, but inflammation, skin clarity, immunity, and even mood.
The important distinction is this: because PHGG works through your gut microbiome, its benefits depend on the unique ecosystem of bacteria living in your gut, and that ecosystem is as individual as your fingerprint.
So, Why Might I Experience Constipation?
If you notice your bowels slowing in the first week or two, it almost always comes down to one of three things:
- You started at full dose immediately, when your gut might be sensitive. Introducing a prebiotic fibre at full strength creates a surge of fermentation activity in the gut. If your microbiome isn’t used to it, this can temporarily disrupt your normal bowel rhythm. Starting slowly allows your gut bacteria to adapt gradually.
- You’re not drinking enough water. Fibre and hydration are inseparable. Without adequate fluid intake, fibre can have the opposite effect to what you’re expecting. Aim for a minimum of two litres of water daily and ideally take DermaGut+ with a glass of water.
- Your gut microbiome needs more time to recalibrate. Some people naturally carry higher levels of methane-producing gut bacteria, which can temporarily slow intestinal transit when fermentation increases. This is common and entirely manageable. It simply means a more gradual introduction is needed.
How Do I Get the Best Results?
Consistency and patience are everything with a prebiotic supplement. Here’s my recommended approach:
- Week 1–2: Start with half a serve, once daily, taken with food and a full glass of water
- Week 3 onwards: Progress to a full serve, ideally split across two meals to distribute fermentation activity evenly throughout the day
If constipation persists: Consider adding magnesium citrate (400mg at night) — it draws water into the bowel and works synergistically alongside DermaGut+ to restore comfortable transit
Clinical studies show that the optimal therapeutic window for PHGG is 5–10g per day, with the strongest benefits emerging between weeks two and four of consistent use. The adjustment period, while occasionally uncomfortable, is a sign that your microbiome is actively shifting, and that is exactly the point.
The Bigger Picture
Your gut is the foundation of your skin health. The gut-skin axis — the bidirectional communication pathway between your gastrointestinal tract and your skin — means that nurturing your microbiome from within will ultimately be reflected in your complexion, your inflammatory response, and your overall vitality. DermaGut+ is formulated to support that process at a cellular level, backed by over 150 clinical studies.
Start gently, stay hydrated, and give your body the four weeks it deserves. The results are worth it.
