Could amino acid deficiencies be making me feel exhausted? It's certainly possible—but it's important to remember that fatigue has many potential causes, which is why persistent or unexplained exhaustion should always be discussed with your GP to rule out underlying medical conditions. If medical causes have been excluded, it's worth considering whether your body has the nutritional building blocks it needs to produce energy and support a healthy nervous system. Amino acids are the building blocks of protein and are essential for countless processes throughout the body. They help repair tissues, support immune function and are used to produce neurotransmitters such as serotonin, dopamine, GABA and noradrenaline—brain chemicals that influence your mood, motivation, focus, resilience and sleep. Periods of prolonged stress can increase your body's nutritional demands. At the same time, many people eat less protein when they're busy, skip meals, rely on convenience foods or experience digestive problems that affect nutrient absorption. Over time, this combination may leave the body with fewer of the raw materials it needs to function at its best. That doesn't mean everyone who feels exhausted has an amino acid deficiency, or that supplements are the right answer for everyone. Fatigue is often influenced by several factors, including sleep, stress, nutrition, hormone balance, gut health, lifestyle and underlying medical conditions. This is why I take an individual approach. During your consultation, we'll explore your health history, symptoms, diet, lifestyle and current medications to build a picture of your overall wellbeing. If appropriate, we may discuss whether increasing dietary protein, improving nutrition or using carefully selected amino acid supplements could form part of your personalised wellbeing plan. My aim isn't simply to recommend supplements—it's to understand why you're feeling exhausted and help you address the possible root causes in a safe, evidence-informed and compassionate way.
