Feeling tired and low on energy is usually down to things you can change: too little or poor-quality sleep, an unbalanced diet, too little movement and stress. Sometimes, though, tiredness is a sign of a nutrient shortfall such as iron or vitamin B12, and only a blood test can confirm that. This guide explains how to rebuild your energy with sleep and food first, when dietary supplements can help, and how to choose them carefully.
Quick answer
- The most common causes of tiredness are lack of sleep, an unhealthy lifestyle and stress, and fixing these comes before any supplement.
- Low iron and low vitamin B12 or folate are well-known causes of tiredness and lack of energy, and only a blood test can show them.
- Supplements fill a gap that already exists; they do not add extra energy if you are not deficient, and they do not replace a balanced diet.
- Talk to a doctor or pharmacist before taking any supplement, especially if you are pregnant or breastfeeding, have a long-term condition or take other medicines.
- If you have felt tired for a few weeks without a clear reason, or it is affecting your daily life, see a doctor to check for health causes.
Why am I tired all the time?
The most common reason for ongoing tiredness is lifestyle, not illness. The NHS page on self-help tips to fight tiredness notes that many cases are due to stress, not enough sleep, poor diet and other lifestyle factors. Cleveland Clinic describes fatigue as extreme tiredness that makes it hard to get through your day and is often not relieved by sleep.
Lifestyle causes
- Sleep: short or broken sleep, late nights on screens and constantly shifting bedtimes.
- Diet: skipping meals, living on sugar and fast food, or following very strict diets.
- Stress: Cleveland Clinic lists stress and burnout among the lifestyle causes of fatigue.
Health causes that need a doctor
Tiredness can signal a condition such as iron deficiency anaemia, thyroid problems, diabetes or sleep apnoea, so avoid self-diagnosis and find the cause before starting supplements.
How can I get my energy back with sleep, food and movement?
Regular sleep, evenly spaced meals and regular activity are the strongest long-term energy boosters. These steps follow NHS advice:
- Keep regular sleep times: go to bed and get up at the same time every day, avoid long daytime naps and take time to wind down before bed.
- Spread out your meals: eat regular meals and healthy snacks every 3 to 4 hours rather than one large meal less often.
- Move, gradually: exercise may be the last thing you feel like doing, but regular activity makes you less tired in the long run, and even a 15-minute walk can give you a boost.
- Cut back on caffeine: limit coffee, tea and energy drinks in the evening.
- Drink water regularly: especially in the Saudi heat.

Which nutrients are linked to energy?
Iron, vitamin B12, folate and vitamin D are the nutrients most linked to tiredness when they run low. Taking them does not boost energy for everyone; a shortfall is simply one possible cause.
Iron
The NHS page on iron deficiency anaemia lists tiredness and lack of energy, shortness of breath and paler skin among its symptoms, sometimes with hair loss, and explains that a doctor confirms it with a full blood count. It also warns to keep iron supplements out of children's reach.
Vitamin B12 and folate
According to the NHS page on vitamin B12 or folate deficiency, low levels can cause extreme tiredness, lack of energy, pins and needles and muscle weakness. A blood test confirms it, and the right way to replace the vitamin depends on the cause.
Vitamin D
The NHS explains that vitamin D helps regulate calcium and phosphate, which keep bones, teeth and muscles healthy. Your body makes it when direct sunlight reaches your skin, and it is found in a small number of foods such as oily fish and egg yolks. People who stay indoors most of the day may not make enough. If you do spend time in the sun, protect your skin with the right product from our guide to the best sunscreen for every skin type.
Magnesium and vitamin C
Magnesium plays a part in energy production and muscle function, and vitamin C helps the body absorb iron from food. A varied diet usually provides enough of both.
When do I need an energy supplement?
You need a supplement when a blood test shows a deficiency, or when your doctor recommends one for a specific situation such as pregnancy or a restricted diet. Food supplements are not medicines; their role is to contribute to the body's normal function when food alone falls short, and they do not replace a balanced diet.
- Before you start: ask your doctor to check your blood count, iron, vitamin B12 and vitamin D.
- Follow the label: use supplements as directed on the pack, and do not stack products with the same nutrients.
- Special situations: check with a doctor or pharmacist before taking supplements during pregnancy or breastfeeding, with a long-term condition or alongside medicines.

How to choose the right energy supplement
- Start with the cause: review your sleep, diet and activity for at least two weeks before thinking about supplements.
- Get tested: if tiredness continues, a blood test shows whether you are low in iron, vitamin B12 or vitamin D.
- Match the product to the gap: iron for low iron, B complex for low B vitamins, and a multivitamin for general support when your diet falls short.
- Read the label: check the ingredients and age group, and watch for the same nutrient appearing in more than one product.
- Ask a pharmacist: especially if you take medicines or are pregnant or breastfeeding.
Common mistakes
- Starting iron without a blood test, even though extra iron does nothing for people who are not deficient.
- Combining a multivitamin with separate supplements that contain the same nutrients without checking with a pharmacist.
- Relying on coffee and energy drinks to make up for lost sleep.
- Ignoring tiredness that lasts for weeks, or comes with weight loss or breathlessness, instead of seeing a doctor.
Frequently asked questions
What are the best supplements for energy?
There is no single best supplement; the right one fills a gap you actually have. Low iron calls for iron, and low vitamin B12 for a B complex. If you are not deficient, sleep, food and activity come first, and a general multivitamin may add support after checking with a pharmacist.
Which vitamins help with tiredness and fatigue?
The vitamins and minerals most linked to tiredness when they run low are iron, vitamin B12, folate and vitamin D. The symptoms overlap, so ask your doctor for a blood test, then choose a supplement based on the result and use it as directed on the pack.
Does vitamin B give you energy?
B vitamins help the body turn food into energy, but they do not work like a stimulant such as coffee. If you are low in vitamin B12, you may feel better once it is replaced; if your levels are normal, a supplement will not add noticeable energy.
How do I know if my tiredness is caused by low iron?
Signs of iron deficiency include tiredness, lack of energy, shortness of breath, paler skin and headaches, and some people notice more hair shedding. These symptoms have other causes too, so the only way to be sure is a full blood count and iron test. Do not start iron before testing.
Are supplements safe to take every day?
Most supplements are safe when used as directed on the pack, but they are not free of risks. Too much iron or vitamin D, for example, can be harmful. Check with a doctor or pharmacist first, especially during pregnancy, breastfeeding or with a long-term condition.
Is sunlight enough to get vitamin D?
Your body makes vitamin D when direct sunlight reaches your skin, but people who spend most of the day indoors or keep most of their skin covered may not make enough. A blood test shows your vitamin D level, and if it is low, your doctor will advise the right way to bring it back up.
When should I see a doctor about tiredness?
See a doctor if you have felt tired for a few weeks without a clear reason, if it affects your daily life, or if it comes with weight loss, mood changes or heavy snoring with pauses in breathing. Your doctor may test for anaemia, diabetes or thyroid problems.
