Do I Really Need Supplements?
By the eva team · · 2 min read
Most healthy teenagers can get many of the vitamins and minerals they need from a varied and balanced diet. Supplements may be useful when a healthcare professional identifies a deficiency, certain foods are restricted or a health condition affects nutrient absorption. More is not always better unnecessary or excessive supplements can cause side effects, duplicate nutrients found in other products or interact with medicines.
1. Do I Really Need Supplements?
Not necessarily. A vitamin or mineral supplement is not something every teenager automatically needs. Supplements are most useful when there is a clear nutritional or medical reason for taking them.
2. Food Usually Comes First
A varied diet provides vitamins and minerals along with protein, fibre, carbohydrates, fats and other components that support growth and health. A supplement can add selected nutrients, but it cannot replace balanced meals.
3. Sometimes Extra Support Is Needed
A healthcare professional may recommend a supplement when a blood test confirms a deficiency, a restricted diet makes a nutrient difficult to obtain or a health condition affects absorption. The right supplement depends on the nutrient and the reason it is needed.
4. Do Not Start Iron By Guessing
Iron supplements may be recommended when testing confirms iron deficiency or iron-deficiency anaemia. Taking more iron than your body needs can cause nausea, constipation, stomach pain or diarrhoea, and very large amounts can be dangerous.
5. More Is Not Better
Taking several products together can accidentally provide repeated doses of the same nutrient. A multivitamin, an iron product and a wellness powder may contain overlapping ingredients, so it is important to check what each product contains.
6. Supplements Can Affect Medicines
Some vitamins and minerals can change how medicines work or affect how other nutrients are absorbed. Tell a doctor or pharmacist about every vitamin, mineral, herbal product and supplement you take even when it was purchased without a prescription.
7. A Supplement Cannot Replace Meals
Even when a supplement is recommended, regular meals still matter. Food provides many nutrients and other components that a tablet or powder cannot fully replace. Think of a supplement as targeted support not breakfast, lunch or dinner.
8. Ask Before You Start
Before taking a supplement, find out why you need it, what it contains and whether it overlaps with another product. Ask a healthcare professional or pharmacist when you are unsure, and never take someone else’s supplement or copy a high-dose routine from social media.
