4 November 2026 (Navroze Bureau) Dietary supplements have become increasingly popular in India, with many people taking multivitamins, vitamin D, vitamin B12, calcium, iron and protein products as part of their daily routines. From working professionals and fitness enthusiasts to older adults, supplements are often considered an easy way to maintain good health and prevent nutritional deficiencies.
However, an important question remains: Do healthy Indians really need to take supplements every day, or can a balanced diet provide all the nutrients required by the body?
Health experts generally emphasise that supplements are not a replacement for a healthy diet. While they can help people meet specific nutritional requirements, taking them without understanding individual needs may not provide additional health benefits.
Supplements Are Not a Substitute for Food
The primary purpose of dietary supplements is to provide nutrients that a person may not be getting in sufficient quantities through regular food.
A balanced diet containing vegetables, fruits, whole grains, pulses, nuts, dairy products and other nutritious foods can provide most essential vitamins and minerals.
Unlike supplements, whole foods also contain dietary fibre, antioxidants and several naturally occurring compounds that work together to support overall health.
For most healthy adults who eat a varied and balanced diet, taking multiple supplements every day may not be necessary.
However, nutritional requirements differ depending on age, lifestyle, dietary preferences and existing health conditions.
Vitamin D Deficiency Remains a Concern
Vitamin D is one of the most commonly discussed nutritional deficiencies in India. Despite the country’s abundant sunlight, many people have inadequate vitamin D levels.
Limited outdoor activity, indoor working routines, clothing habits, skin pigmentation and other lifestyle factors can influence vitamin D production.
Vitamin D plays an important role in calcium absorption, bone health and normal muscle function.
People with confirmed deficiency may require supplements based on medical advice. However, taking high doses without medical supervision can lead to excessive calcium levels and other complications.
Vitamin B12 and Vegetarian Diets
Vitamin B12 is another important nutrient, particularly for people following vegetarian or vegan diets.
The vitamin is naturally found mainly in animal-based foods such as milk, dairy products, eggs, fish and meat. People who avoid animal products may have a higher risk of inadequate B12 intake.
Vitamin B12 is essential for red blood cell formation, DNA production and normal nervous system functioning.
A deficiency can cause tiredness, weakness, anaemia, numbness and neurological problems.
People with suspected deficiency should consult a healthcare professional and consider appropriate testing before starting treatment.
Iron and Calcium: Not Everyone Needs Supplements
Iron and calcium are also commonly consumed through dietary supplements. However, taking them without identifying a nutritional requirement may be unnecessary.
Iron is essential for haemoglobin production and oxygen transportation throughout the body. Women with heavy menstrual bleeding, pregnant women and individuals with certain medical conditions may have an increased risk of iron deficiency.
Calcium supports bone strength, muscle contraction and nerve function. Milk, curd, paneer, green leafy vegetables and fortified foods can contribute to daily calcium intake.
People who cannot meet their requirements through food or have a medically identified deficiency may need supplementation.
Excessive iron intake can cause digestive problems and, in some circumstances, serious health complications. Similarly, excessive calcium supplementation may increase the risk of kidney stones in susceptible individuals.
Can Taking Multivitamins Every Day Improve Health?
Multivitamins are widely marketed as an easy way to improve energy, strengthen immunity and prevent diseases.
However, taking a multivitamin does not automatically make someone healthier. Research has not consistently demonstrated that routine multivitamin use prevents major chronic diseases in otherwise healthy adults.
People with nutritional deficiencies, restricted diets or increased nutritional requirements may benefit from specific supplements. But healthy individuals should not assume that taking more vitamins will provide greater protection against illness.
The correct approach is to identify nutritional gaps rather than consuming several products without a clear reason.
Who May Actually Need Daily Supplements?
Although supplements are not necessary for everyone, certain groups may benefit from them.
These include pregnant women, older adults, people following restrictive diets, individuals with diagnosed nutritional deficiencies and patients suffering from conditions that affect nutrient absorption.
People recovering from certain illnesses or undergoing specific medical treatments may also require additional nutritional support.
Doctors may recommend folic acid during pregnancy, vitamin B12 for people with inadequate intake or absorption, and vitamin D for individuals with confirmed deficiency or increased risk.
The type, dosage and duration of supplementation should depend on individual requirements.
Risks of Taking Too Many Supplements
One common misconception is that vitamins and minerals are always safe because they are available without a prescription.
However, excessive consumption can create health problems. Fat-soluble vitamins such as A, D, E and K can accumulate in the body. High doses of certain minerals can also interfere with the absorption of other nutrients or cause toxicity.
Combining multiple supplements can increase the risk of accidentally consuming excessive amounts of the same nutrient.
Some supplements may also interact with prescription medicines and affect their effectiveness.
Therefore, consulting a qualified healthcare professional before starting a new supplement routine is important.
A Balanced Diet Should Remain the Priority
For most healthy Indians, the foundation of good nutrition should be a balanced and diverse diet rather than a collection of supplement bottles.
Regular consumption of seasonal fruits, vegetables, pulses, whole grains, nuts and appropriate protein sources can help meet nutritional requirements.
Adequate sleep, regular physical activity, hydration and healthy lifestyle habits are equally important for maintaining overall well-being.
Supplements can play a useful role when there is a genuine nutritional need, but they should not be treated as everyday medicines or automatic requirements.
Ultimately, the decision to take supplements should be based on dietary habits, medical history and individual nutritional needs. A personalised approach is more appropriate than following popular health trends or taking products simply because they are widely advertised.
