The Best Supplements for Coeliac Disease (And Health Tips to Stay Fit & Well)
Living with coeliac disease means more than just avoiding gluten. Even on a strict gluten-free diet, many of us are at higher risk of nutritional deficiencies, because years of damage to the gut lining can affect how well we absorb key vitamins and minerals.
I know this first-hand. When I was diagnosed 17 years ago, nobody really talked about supplements. It was all about cutting out gluten and hoping for the best. Over the years I've learned a lot about what my body actually needs, and I want to share that with you.
Please note: I'm not a medical professional. Always speak to your GP or a registered dietitian before starting any new supplements, especially if you've been recently diagnosed.
Key Supplements to Consider if You're Coeliac
1. Iron
Iron deficiency is one of the most common issues in coeliac disease, often because the part of the gut responsible for absorbing iron gets damaged. Symptoms include fatigue, brain fog, and feeling generally run down. Your GP can test your iron levels, if they're low, supplementing is really important.
2. Vitamin D
Vitamin D deficiency is widespread in the UK anyway, but coeliacs are at even greater risk. It's essential for bone health, immune function, and mood. A daily supplement of 1,000–2,000 IU is commonly recommended, but check with your doctor for the right dose for you.
3. B12 and Folate
Both are crucial for energy, nerve function, and red blood cell production. They're often low in coeliacs, particularly in the early stages after diagnosis. A good B-complex supplement can help support these levels.
4. Calcium and Magnesium
Because dairy can sometimes be tricky for coeliacs (especially newly diagnosed), calcium intake can be lower than ideal. Magnesium supports muscle function, sleep, and energy, and is often depleted in people with gut conditions.
5. Zinc
Zinc plays a role in immune health, wound healing, and gut repair. It's worth checking your levels if you've been unwell for a while before diagnosis.
6. A Good Multivitamin
A high-quality multivitamin formulated for gut health or absorption issues can be a good safety net, particularly in the first year after diagnosis when your gut is healing.
My Top Health Tips for Staying Fit & Well with Coeliac Disease
- Get your bloods checked regularly. Annual blood tests through your GP are standard care for coeliacs, make sure you're getting them. Ask for iron, B12, folate, vitamin D, calcium, and thyroid if possible.
- Focus on whole, naturally gluten-free foods. Lean proteins, vegetables, fruit, legumes, and gluten-free grains like quinoa, buckwheat, and brown rice are your friends. They're nutrient-dense and much better for gut healing than processed gluten-free alternatives.
- Stay hydrated. It sounds simple, but many coeliacs experience gut issues that can affect hydration. Water, herbal teas, and electrolyte-rich foods all help.
- Move your body gently. In the early stages of healing, intense exercise can be draining. Walking, yoga, and swimming are great options that support wellbeing without overloading your system.
- Support your gut with fermented foods. If you tolerate them, foods like natural yoghurt, kefir, and sauerkraut can help support a healthy gut microbiome, which is often disrupted in coeliac disease.
- Prioritise sleep. Your body does most of its repair work overnight. If fatigue is a big issue, protecting your sleep is one of the most powerful things you can do.
- Be kind to yourself. Coeliac disease is a lifelong condition. The learning curve is real. Give yourself grace, especially in the early days.
A Final Word
Managing coeliac disease well goes beyond the gluten-free diet. Paying attention to your nutritional health, getting regular check-ups, and making small lifestyle changes can make a huge difference to how you feel day to day.
