1
Contains NHS recommended dose of vitamin D3 for immune and gut interaction support
At the heart of this formula is Vitamin D. Deficiency of Vitamin D is highly prevalent amongst the UK population, and the NHS recommends taking a supplement of at least 400iu per day.
Vitamin D is obtained naturally from two sources: sunlight and food. It is, however, found in only a few foods and we get the majority of our intake from the action of sunlight on our skin. Happy Gut's unique formula contains your daily recommended dose alongside many more carefully selected ingredients to support your wellbeing.

Streamlined routine: one smart daily capsule
In a world where people are taking more supplements than ever, Happy Gut keeps things simple. It’s just one capsule a day to start, delivering 20 billion friendly bacteria across 10 diverse strains, inulin and FOS prebiotics, digestive enzymes and your NHS recommended dose of vitamin D3.
Streamline your routine, without losing out on the support you're looking for.
3
inulin and FOS prebiotics for microbiome support
Inulin & FOS — prebiotic fibres naturally found in plants like chicory, garlic and artichoke — work as food for the beneficial bacteria already living in your gut. Unlike probiotics, they don't introduce new bacteria; they nourish what's already there. This Happy Gut formula combines both long and short chain prebiotic fibres for a complementary, broad-spectrum effect. A thoughtful addition to our botanical blend — quietly working where it matters most.
4
digestive enzymes to support nutrient breakdown
The inclusion of lipase, amylase, and protease enzymes helps break down fats, carbs, and proteins from food. This may support the absorption of nutrients during digestion. Prebiotic fibres help nourish beneficial bacteria in the gut. The result is a comprehensive supplement that fits easily into any gut wellness routine.

Crafted by herbalists, backed by heritage
From our Edinburgh beginnings in 1860, Napiers motto has been: tried, tested, trusted. Napiers Happy Gut carries that same spirit. Each serving contains 20 billion friendly bacteria. What you’ll notice: the confidence that you’re using a supplement grounded in herbalist experience and modern evidence rather than a generic mass-market product.
