Risk of nutrient deficiencies
Iron, B12, vitamin D, calcium, iodine and omega-3 are the most common ones people fall short on. We map, prioritise and correct.
In short
What are nutrient deficiencies and malnutrition?
Nutrient deficiencies occur when we don't get enough of one or more nutrients over time — either from the diet or due to poor absorption.
Malnutrition is a broader condition where the body doesn't get enough energy, protein or nutrients to maintain health and function.
Restrictive diets, chronic illness, old age and certain life stages all increase the risk.

Does this sound familiar?
This might sound like your situation
Symptoms often come on gradually and can be vague.
- Blood tests show low levels you want to correct
- You're tired, cold or losing hair
- You use supplements without knowing if they're the right ones
- Your diet is restricted by allergy, illness or choice
- You want a plan followed up with new tests
SmartEating recommends
What makes the biggest difference?
Correcting nutrient deficiencies works best when the diet is prioritised first and supplements are added where needed.
Blood test mapping
Testing shows which nutrients are actually low, avoiding guesswork or unnecessary supplements.
Diet-first correction
Food sources are prioritised before supplements, since they often cover several nutrients at once.
High-risk groups
Restrictive diets, older age, pregnancy and chronic illness all raise the risk and need closer follow-up.
Absorption factors
Illness, medication and age can reduce nutrient absorption even with adequate intake.
Follow-up testing
Repeating blood tests confirms whether corrections are working over time.
When should you contact a doctor?
Persistent fatigue, weight loss or a change in general condition should always be medically assessed.
- Unexplained weight loss
- Persistent fatigue or weakness
- Blood tests showing low levels
- Reduced general condition in older adults
- Prolonged loss of appetite
A clinical dietitian can help with diet and supplements, but doesn't replace medical investigation of underlying causes.
Common questions
What people ask us most often.
Do I need blood tests first?
It often helps — but we can start the mapping regardless.
Personal nutrition
No one with risk of nutrient deficiencies is exactly the same
Age, everyday life, activity level, other conditions and what you actually enjoy eating determine what works for you.
That's why two people in the same situation need different advice. SmartEating AI learns your situation over time and tailors suggestions to your body, goals and everyday life.
- Blood tests show low levels you want to correct
- You're tired, cold or losing hair
- You use supplements without knowing if they're the right ones
- Your diet is restricted by allergy, illness or choice
- You want a plan followed up with new tests
The goal is to safely rebuild your status — first through diet, and with supplements where needed.
SmartEating makes it easier to build meals around the nutrients you're lacking, with a shopping list and reminders.
A clinical dietitian can prioritise what needs correcting first, track blood tests over time and collaborate with your GP.

The knowledge behind the advice
Vitamins and minerals
Vitamins and minerals are micronutrients the body needs in small amounts, but they are essential for nearly all bodily functions. A varied diet with plenty of vegetables, fruit, whole grains and good protein sources usually covers the need without supplements.
Iodine
Iodine is a mineral the body needs to make thyroid hormones, which govern metabolism and are essential for brain development in the foetus and young children. In Norway, iodine is one of the nutrients where both too little and too much can cause problems — and where your diet matters a great deal.
Legumes
Legumes such as beans, lentils and chickpeas are among the most nutrient-dense and sustainable foods available. They combine plant-based protein with abundant fibre, and are a valuable food group whether you eat a lot of meat or very little.
