When we hear the word ‘zinc’, most of us immediately think of a strong immune system, fighting acne, or healthy hair and nails. But did you know that this trace element is absolutely vital for your digestive system? Without zinc, your body wouldn’t be able to break down food properly and absorb the essential nutrients from it.

Here’s an overview of why zinc is so essential for your tummy.
1. Gastric acid stimulator
The stomach needs acid (hydrochloric acid – HCl) that is strong enough to break down proteins and destroy any harmful bacteria in food. Can you guess what the body needs to produce it? That’s right, zinc.
Zinc plays a role in the production of the enzyme responsible for producing this acid. If you are deficient in zinc, the production of stomach acid decreases. Food may then take much longer to digest in your stomach, which often causes bloating, heartburn and an unpleasant feeling of heaviness after eating.
2. A motor for digestive enzymes
Digestion does not end in the stomach. Food travels on to the small intestine, where the pancreas secretes digestive enzymes. These enzymes break down carbohydrates, fats and proteins into tiny particles that the body can utilise.
Zinc acts as a so-called cofactor (helper) for many of these enzymes. To put it simply: without zinc, these enzymes would be like cars without ignition keys – they would be there physically, but they wouldn’t work at all.
3. Protector of the intestinal barrier
The intestines are lined on the inside with a thin layer of cells that acts as a security barrier. It allows nutrients to pass into the body, but blocks toxins and bacteria. This mucous membrane must be renewed very quickly and continuously.
As zinc is essential for cell growth and division, it plays a vital role in maintaining a strong and healthy intestinal wall. It thus helps to prevent a condition known as ‘leaky gut syndrome’, in which substances that do not belong there enter the bloodstream and can cause inflammation.
When diet isn’t enough: How to choose and take zinc supplements correctly?
Sometimes, due to stress, poor digestion, a vegan diet or increased physical activity, we are unable to get enough zinc from food alone. That’s when dietary supplements come into play. However, not all zinc is the same. When choosing a supplement, pay particular attention to the chemical form in which the zinc is present.

Form Matters (Organic vs. Inorganic)
Chelated and organic forms (Excellent absorption): Look for names such as zinc bisglycinate, zinc picolinate or zinc citrate. Your body recognises these forms best; they pass easily through the intestinal wall and do not cause stomach upset.
Zinc Forte by Dr LUCULLUS is a high-quality supplement you can rely on to support your body’s defences. It provides excellent support for your skin, hair, nails and brain function. It’s the right choice if you’re looking for a reliable supplement to incorporate into your daily routine.
Inorganic forms (poor bioavailability): Often, cheaper products contain zinc oxide or zinc sulphate. These forms have low bioavailability (the body utilises only a fraction of them) and, in more sensitive individuals, may cause nausea or cramps when taken on an empty stomach.
How can you ensure you get enough zinc from your daily diet?
The body cannot produce zinc itself, nor can it store large amounts of it over the long term. We therefore need to consume it regularly through our diet. Fortunately, it is found in many common and tasty foods:
Seeds and nuts: Pumpkin seeds (one of the best plant-based sources), cashew nuts, almonds.
Meat and poultry: Beef, turkey and high-quality red meat.
Seafood: Oysters are by far the richest source of zinc, but crabs and prawns are also good sources.
Pulses: Chickpeas, lentils and various types of beans.
Wholemeal products: Oat flakes, quinoa.
Zinc may not get as much attention in adverts as vitamin C or probiotics, but it does a huge amount of behind-the-scenes work for our digestion. It really isn’t just a quick fix when your throat starts to feel scratchy in winter. It’s the imaginary key that gets your stomach going, revives your digestive enzymes and builds a protective shield for your gut.
