Could This Overlooked Nutrient Help Calm Your Eczema?

Jun 3, 2025 | Allergies/Intolerances, Eczema

When it comes to eczema, the list of potential causes can feel endless – from skin barrier disruption and microbiome imbalance to food intolerances and stress. But there’s one nutrient that rarely gets the spotlight, despite its far-reaching benefits for skin and beyond: glycine.

Glycine is a small but mighty amino acid, naturally produced by the body and found in collagen-rich foods. It plays a key role in skin healing, immune regulation, detoxification, gut integrity, and even sleep – all areas that matter deeply in eczema.

Why Glycine Matters for Eczema

Glycine helps your body build collagen – the protein that keeps skin strong, supple, and hydrated. It also supports glutathione production, your body’s master antioxidant and detoxifier. If detoxification pathways are under pressure (which is common in eczema), glycine can help reduce inflammation and support liver function.

Glycine also strengthens the gut lining and calms the nervous system, both of which are vital for people with eczema who struggle with food sensitivities, stress, poor sleep, or digestive issues.

Are You Getting Enough?

While your body can make glycine, demand often exceeds supply during times of stress, illness, or inflammation. You can boost intake through foods like:

  • Bone broth or slow-cooked meats with skin and connective tissue
  • Collagen or gelatine powder (watch for histamine sensitivity)
  • Skin-on poultry and tougher cuts of meat

A typical modern diet – heavy in muscle meats and low in collagen-rich cuts – can easily become glycine-poor.

Is Glycine Right for You?

Glycine isn’t a cure-all, but it may be especially helpful if you:

  • Are recovering from infection, injury, or a major eczema flare
  • Experience poor sleep or high stress
  • React to skincare products or struggle with detoxification
  • Have digestive issues or suspected leaky gut

For children with eczema, glycine-rich foods like well-strained broth or skin-on chicken can be a gentle way to support healing.

Final Thoughts

Glycine might not be trendy, but it’s a quiet hero in skin repair and immune balance. If eczema flares keep returning despite creams or diet changes, exploring your glycine status could be a missing piece of the puzzle.

WHO AM I?

I’m Jessica Fonteneau, the Eczema and Digestive Health Nutrition Expert. I’ve worked with hundreds of clients to help them change their diets, better manage their flares, and find relief.

My vocation is to help those with eczema and digestive issues, because I have suffered with these interlinked conditions since I was 6 months old, and I truly know what it is like to experience these debilitating conditions.

Every client I have ever worked with has their own triggers and ideal nutrition. There is no such thing as ‘one-size-fits-all’. Whether you work with me one-to-one or use my guided tools, my objective is to help you uncover what works best for you, so that you take back control and experience relief.

My guided programmes are only suitable for adults as children have very specific nutrition requirements. I do, however, work with many child clients as part of my clinic.

We have been working with Jessica for a while now for my son’s eczema and many food intolerances. We have come a long way with him tolerating a lot more foods whilst previously being on such a limited diet. We have seen a huge difference in his skin too. One thing we love about working with her is that she is highly knowledgeable about how the gut works, what food works well and how to carefully introduce food to increase tolerance. We would honestly be so lost without her support. She provides timely responses if we have any concerns and always has such an empathetic approach if we have a little bump in our journey.

I would recommend Jessica to any parents struggling with their childs eczema or any individuals out there trying to figure out eczema, want to naturally heal through foods and identifying triggers to get relief in your flares.

I have no hesitation in highly recommending Jessica. She really knows her stuff! I first consulted her six months ago with lack of appetite, lack of energy and depression, not unrelated to having recently become a widow. Right from the start I was very impressed at the way Jessica really listened to me during her consultations, writing very thorough and detailed reports afterwards with her holistic recommendations . Six months later I am eating better, have more energy and even able to go dancing regularly (which is not bad for a 74 year old!) Thank you Jessica

Jessica has helped save my sanity when I was suffering from unexplained symptoms. She very quickly identified that this could be the side effects of an overdose of supplements and once I discontinued these, I felt better quickly. I continued working with Jessica on other food and lifestyle questions and always found her extremely helpful, patient and knowledgable. I would recommend her to friends and family.

Jessica was a fantastic support when my 1 year old developed severe eczema. We worked together to identify the root cause of her symptoms and Jessica advised an easy to follow, realistic and successful protocol for us to follow to help her manage this. My daughter’s skin significantly calmed down within weeks and although it’s been a long journey her eczema has now disappeared. Jessica has extensive knowledge on eczema and created a personal plan for us to follow. She was always available and willing to help and reassure where needed. I wouldn’t hesitate to recommend her to anyone looking for support with nutrition or skin issues. Thank you so much!

We have been working with Jessica Fonteneau for several months now. From the very first consultation Jessica was empathetic and listened attentively to concerns about our son's health and Eczema. Since then we are really seeing the benefits of her advice and nutritional recommendations. I have learnt so much! Jessica's offers practical and manageable solutions and doesn't bombard you with too much information or unattainable goals. I am so glad we found Jessica Fonteneau and highly recommend.

After struggling with severe eczema nearly all my life and trying countless steroid creams/emollients prescribed by dermatology consultants I have finally been able to take back control of my skin through Jessica's trigger identifying diet. The skills and tool kit she has provided me with have been life changing and I'm confident I have everything I need to continue my journey without the help of a professional. Jessica has helped me to feel empowered through understanding my body and I am very grateful.
Jessica has helped me and my son so much with some persistent eczema on his face. She put together a highly comprehensive plan and considered all aspects of his diet, routine and lifestyle. She has checked in several times since our appointment and I felt she really cared about his health and well-being. Highly recommend to any parents whose child is suffering from an allergy or skin disorder!
