If you're experiencing fatigue, it's worth getting a blood test before assuming lifestyle causes. Common deficiencies that cause tiredness include iron (especially in women), vitamin B12, vitamin D, and thyroid issues.
For vitamin D specifically: most people in the northern hemisphere are deficient, especially in winter. Symptoms include fatigue, low mood, muscle weakness, and frequent illness. A blood test will confirm. Supplements are cheap — most doctors recommend 1000-2000 IU daily as maintenance.
Iron deficiency anaemia is also very common, especially if your diet is low in red meat. You might feel exhausted, look pale, get short of breath easily, and have cold hands. Ferrous sulphate tablets are the standard treatment — take with vitamin C to improve absorption.
B12 deficiency is common in vegans and vegetarians since it's mainly in animal products. Symptoms include extreme fatigue, brain fog, tingling in hands and feet. B12 supplements or injections resolve it.
See your GP first — a simple blood test rules out or confirms these quickly.

Gut health affects far more than just digestion — it influences immune function, mental health via the gut-brain axis, energy levels, and even skin health. The gut microbiome contains trillions of bacteria that perform essential functions.
The most evidence-based ways to improve gut health: eat more fibre. Most people eat 15g daily when the target is 25-30g. Fibre feeds beneficial gut bacteria. Aim for 30 different plant foods per week — this is easier than it sounds when you count spices and herbs.
Fermented foods introduce beneficial bacteria: yoghurt with live cultures, kefir, kimchi, sauerkraut, and kombucha. Even a small daily serving helps. These are especially useful after antibiotics, which can wipe out gut bacteria.
Avoid unnecessary antibiotics. Reduce ultra-processed food consumption — emulsifiers and artificial sweeteners appear to negatively affect the microbiome. Manage stress, which directly impacts gut motility and bacterial composition via the gut-brain axis.
