Get gut healthy with Kollo
Looking After Your Gut Health: A Practical Guide
Our guts can be difficult to please, especially as we age. One day you're enjoying pizza and a glass of wine right before bed, and the next, the slightest thing throws you off-kilter. Gut health is genuinely intricate, and balance is the key. Below are some practical, evidence-led habits for feeling better from the inside out — plus an honest look at where a supplement like Kollo does and doesn't fit, because we'd rather give you the truth than a tidy marketing story.
Signs Your Gut Might Need Attention
Wondering whether your gut is happy? Common signs of digestive upset include gas, bloating, diarrhoea and constipation. Frequent heartburn or feeling unwell after meals can also point to it. Less obvious signals can include new food intolerances, changes in appetite and poor sleep.
An important honesty note: many of these symptoms overlap with conditions that need proper medical assessment — from IBS to coeliac disease to food allergies. If symptoms are persistent, severe, or come with weight loss, blood, or pain, please see your GP rather than reaching for a supplement. No drink fixes a medical problem.
Stress Less — It Really Does Reach Your Gut
The gut-brain connection is one of the better-established areas of digestive science. Stress and anxiety can be a genuine trigger for tummy troubles, so building calm into your day is more than a nice-to-have. Try a few minutes of slow, deep breathing, a short walk, or giving meditation a go. It won't solve everything, but for stress-driven symptoms it's one of the most evidence-supported levers you have.
Keep Track of What and When You Eat
A food diary isn't just for weight management. Logging what you eat — and when — can help you spot patterns between particular foods and symptoms, which is useful information to bring to a GP or dietitian rather than guesswork. If heartburn is your issue, eating your main meal earlier in the evening rather than just before bed is a simple, sensible change worth testing.
The Foundations That Genuinely Help
- Eat a variety of plants — a diverse, fibre-rich diet is one of the most consistently supported ways to nurture healthy gut bacteria.
- Include fermented foods — yoghurt, kefir, sauerkraut and kimchi introduce beneficial microbes.
- Stay hydrated — water supports digestion and regularity; our complete guide to electrolytes covers staying properly topped up.
- Move regularly — physical activity supports healthy gut motility.
- Prioritise sleep — poor sleep and gut health influence each other, so it's worth protecting.
Where Does Collagen Fit? An Honest Answer
You'll see a lot of confident claims online that collagen "heals the gut lining" or "reduces gut inflammation." Here's the truthful picture. The gut lining is collagen-rich tissue, so there's a logical mechanistic rationale, and some laboratory and animal studies are genuinely interesting. But the human clinical evidence is still limited — mostly small pilot studies relying on self-reported symptoms — and the findings aren't all in one direction. That's why we don't claim Kollo repairs your gut or reduces inflammation. It would be overstating what's actually known, and that's not how we do things.
What we can say honestly is this: Kollo contains vitamins B1, B5, B6, B12 and C, several of which carry authorised UK health claims for contributing to normal energy-yielding metabolism and the reduction of tiredness and fatigue. And its best-evidenced benefit lies elsewhere — a 2023 meta-analysis of 26 randomised trials in Nutrients found hydrolysed collagen significantly improved skin hydration and elasticity. So if you take Kollo, take it for what it's genuinely good at — and let your gut-health plan rest on the food, sleep, movement and stress habits above.

| Stress management | Well supported via the gut-brain connection |
| Hydration, sleep, movement | Foundational and well supported |

A happy gut is built mostly in the kitchen and through your daily habits — varied plants, fermented foods, hydration, movement, sleep and managing stress. Those are the things the evidence backs most strongly, and they cost nothing but attention. A supplement can sit alongside a healthy routine, but it isn't the foundation, and anyone telling you a collagen drink fixes your gut is getting ahead of the science.
If you take Kollo, take it for what it's genuinely good at: its 10g daily dose of the most researched form of collagen, backed by meta-analyses for skin, with vitamins carrying authorised claims for energy and reducing tiredness. Our complete guide to liquid marine collagen has the full detail, and for women thinking about wellness more broadly in midlife, our women's wellness guide for over 40s ties it all together.
