Feeling tired after a long day is normal. But if you often feel drained, struggle to concentrate, or wake up feeling exhausted even after a full night's sleep, it may be worth looking at your everyday habits including your diet.
Your body needs a steady supply of energy and essential nutrients to support normal functions. When your diet does not provide enough of certain nutrients, you may experience symptoms such as fatigue, weakness, or difficulty concentrating.
However, feeling tired all the time does not automatically mean you have a nutritional deficiency. Poor sleep, stress, dehydration, medical conditions, and other factors can also contribute to fatigue.
Understanding some common nutrition gaps can help you make more informed food choices and recognise when professional advice may be needed.
1. Iron: A Nutrient That Helps Carry Oxygen
Iron is essential for making haemoglobin, a protein in red blood cells that carries oxygen throughout the body. When iron levels become too low, the body may not deliver oxygen as effectively, and iron-deficiency anaemia can develop.
Common symptoms may include:
-
Tiredness and low energy
-
Weakness
-
Pale skin
-
Shortness of breath during activity
-
Headaches or dizziness
Iron deficiency can be associated with inadequate dietary intake, blood loss, pregnancy, or problems with iron absorption.
Foods to include: Lentils, chickpeas, beans, spinach, sesame seeds, and iron-fortified foods. Pairing plant-based iron sources with vitamin C-rich foods such as lemon, guava, or oranges can help improve iron absorption.
If you suspect iron deficiency, a healthcare professional can recommend appropriate tests. Avoid taking iron supplements without guidance, as excess iron can be harmful.
2. Vitamin B12: Important for Nerves and Red Blood Cells
Vitamin B12 helps maintain healthy nerve cells and supports the production of red blood cells. A deficiency can cause tiredness and weakness, and it may also affect the nervous system.
Some people may be more likely to have low B12 levels, including those who follow a strict vegan diet, older adults, and people with certain digestive conditions or absorption problems.
Possible signs include:
-
Persistent fatigue
-
Weakness
-
Tingling or numbness in the hands and feet
-
Difficulty with balance
-
Problems with memory or concentration
Foods to include: Milk, curd, paneer, and foods fortified with vitamin B12. People who avoid animal-derived foods may need fortified foods or supplements, depending on their dietary intake and individual needs.
A blood test can help determine whether B12 levels are low. Early evaluation is important because prolonged deficiency can cause lasting nerve damage.
3. Folate (Vitamin B9): Supports Healthy Red Blood Cell Formation
Folate is a B vitamin that helps the body produce healthy red blood cells and supports normal cell growth. A prolonged lack of folate can lead to a type of anaemia that may cause fatigue and weakness.
Folate deficiency may be more likely when a person's diet lacks variety or when the body has difficulty absorbing nutrients.
Foods to include:
-
Spinach and other leafy green vegetables
-
Chickpeas and kidney beans
-
Peas and broccoli
-
Fortified cereals and grains
Including these foods regularly can help support your overall nutrient intake. If you have ongoing fatigue, a healthcare professional can determine whether testing for folate deficiency is appropriate.
4. Vitamin D: Important for Muscles and Bones
Vitamin D helps the body absorb calcium and supports bone and muscle function. Low vitamin D levels can sometimes be associated with muscle weakness, although tiredness alone does not establish a deficiency.
Vitamin D is found in a limited number of foods, including fortified products and certain mushrooms. Sunlight exposure can also contribute to vitamin D production, but the amount varies with factors such as skin tone, location, season, and time outdoors.
If you are concerned about vitamin D, discuss your symptoms and risk factors with a healthcare professional. Supplements may be recommended in certain circumstances, but taking high doses without guidance is not advisable.
5. Not Eating Enough Protein or Overall Food
Sometimes, low energy is not caused by a single vitamin deficiency. Eating too little overall or not getting enough protein can make it harder to meet your body's nutritional needs.
Protein helps maintain muscles and supports tissue repair. Carbohydrates provide an important source of energy, while dietary fats also supply energy and support normal body functions.
Try to include a mix of foods in your daily meals:
-
Dal, beans, chickpeas, paneer, curd, and tofu for protein
-
Roti, rice, oats, and millets for carbohydrates
-
Nuts, seeds, and suitable cooking oils for fats
-
Fruits and vegetables for fibre, vitamins, and minerals
Skipping meals, following restrictive diets, or frequently replacing meals with tea and snacks may make it difficult to get enough nutrients. A consistent eating pattern with satisfying, varied meals can help support everyday energy needs.
6. Dehydration: An Often-Overlooked Cause of Low Energy
Not drinking enough fluids can contribute to tiredness, headaches, dizziness, and difficulty concentrating.
Your fluid needs may increase in hot weather, during physical activity, or when you are unwell. Keeping water nearby and drinking regularly throughout the day can help maintain hydration.
Water-rich foods such as fruits, vegetables, and soups can also contribute to your fluid intake. If you experience ongoing dizziness or significant weakness, do not assume dehydration is the only possible cause.
How to Build an Everyday Nutrition Routine for Better Energy
You do not need an elaborate diet to support your nutritional needs. Start with a few manageable habits:
-
Eat regular, balanced meals: Include a mix of grains, protein-rich foods, vegetables, and healthy fats.
-
Add variety: Rotate different fruits, vegetables, pulses, and whole grains throughout the week.
-
Stay hydrated: Keep water accessible and drink regularly.
-
Avoid overly restrictive diets: Make sure your meals provide enough food to meet your individual needs.
-
Prioritise sleep: Consistent, sufficient sleep is important for everyday energy and concentration.
-
Pay attention to persistent symptoms: Ongoing fatigue deserves attention rather than relying on supplements alone.

Final Thoughts
Feeling tired all the time can have many possible causes. Iron, vitamin B12, folate, and vitamin D are among the nutrients involved in important body functions, and inadequate intake of certain nutrients may contribute to fatigue.
A varied diet, regular meals, adequate hydration, and sufficient sleep can support everyday wellbeing. If fatigue persists, getting the cause checked is more useful than guessing which supplement you need.
Frequently Asked Questions
Which nutritional deficiencies can cause tiredness?
Iron, vitamin B12, and folate deficiencies can cause fatigue, particularly when they lead to anaemia. Other nutritional issues may also affect wellbeing, but fatigue alone cannot identify a specific deficiency.
Can low vitamin D cause fatigue?
Low vitamin D levels may be associated with muscle weakness and other symptoms, but tiredness alone does not confirm a deficiency.
What foods can help support everyday energy?
Balanced meals containing whole grains, pulses, dairy or suitable alternatives, vegetables, fruits, nuts, and seeds can help provide a range of nutrients and energy.
Should I take a multivitamin if I feel tired?
Not necessarily. Fatigue can have many causes. A healthcare professional can help determine whether a supplement or further testing is appropriate.
