Autoimmune and Nutrient Deficiencies
Autoimmune and Nutrient Deficiencies
In the words of Dr Peter Osborne, “The importance of nutrition can't be argued. It's absolutely critical.”
Why do we require nutrients though?
Essential nutrients found in food—such as vitamins, minerals, amino acids, carbohydrates, and healthy fats—are the building blocks your body relies on to function properly. Each nutrient has its own specific job, and everyone’s exact needs are unique to their body and health history.
One crucial thing to consider is the "why" behind nutrient deficiencies—especially when living with an autoimmune condition. Low levels are not always about what is missing from your plate. They can happen because of:
Dietary gaps: Not eating enough nutrient-dense whole foods
Impaired gut absorption: Inflammation in the digestive tract (such as in Coeliac disease) making it harder for your body to absorb nutrients from food
Higher internal demand: An overactive immune system and chronic inflammation using up vitamins and minerals faster than usual
Some of the most common shortfalls seen in autoimmune health include:
Vitamin D (vital for immune regulation and bone health)
Vitamin B12 (essential for energy, nerve health, and red blood cells)
Iron and Magnesium (key for energy, muscle relaxation, and thyroid function)
Zinc (supports gut lining repair and balanced immune signalling)
Omega-3 Fatty Acids (crucial for calming systemic inflammation)
And—believe it or not—Water (even mild dehydration worsens fatigue, brain fog, and digestion)
A Quick Tip: Test Before You Guess
If you suspect you are running low on key nutrients, resist the urge to immediately buy lots of high-dose supplements. Nutrients work in delicate balance—for instance, taking too much zinc can actually deplete your copper levels, and excess iron can cause inflammation.
Instead, book a routine appointment with your GP and ask for a blood panel to check your baseline levels—particularly Vitamin D, Vitamin B12, folate, and ferritin (stored iron). Knowing your exact numbers allows you and your healthcare team to target what your body genuinely needs safely and effectively.
Have you ever had your vitamin and mineral levels checked, or discovered any nutrient deficiencies on your health journey?
