A growing concern is emerging in India as deficiencies in Vitamin B12, D, and iron creep into lives across various age groups and lifestyles. Today’s fast-paced living, characterized by unhealthy eating and minimal sunlight, plays a significant role in this trend. These nutrients are crucial—not just for maintaining energy and boosting immunity, but for our overall well-being.
Fatigue that stays through the day. Hair fall that feels seasonal but never really stops. A constant sense of low energy that sleep does not fix. These are generally brushed aside as stress or a busy routine.But in many cases, the body is quietly running low on essentials, Vitamin B12, Vitamin D, and iron.Across cities and small towns alike, more people are testing deficient than ever before. What is striking is that this is not limited to one age group or lifestyle. Office workers, students, homemakers, even those who believe they eat “well” are affected.So, what changed? And more importantly, what can be done daily to fix it?
Why deficiencies are rising in everyday life
The modern routine looks efficient on the outside but is often nutritionally poor.Meals are rushed, sunlight is limited, and movement is minimal.Dr Chirag Tandon explains it clearly, “Vitamin B12, Vitamin D, and Iron deficiencies are becoming increasingly prevalent across all age groups due to a modern way of life that has caused deficiencies in these nutrients. Lifestyles that are sedentary/indoor, intermittent eating habits and increased reliance on processed foods have been cited as several contributing factors.”This shift is subtle. Breakfast gets skipped. Lunch is ordered. Dinner is late. Sun exposure is replaced by screen time. Over time, the body adapts, but at a cost.Government-backed data supports this trend. A large national survey publihsed by theJournal of Nutritional Sciencefound widespread micronutrient deficiencies across India.
The silent role these nutrients play
These deficiencies do not scream for attention at first. They whisper. Vitamin B12 supports nerve health and brain function.Vitamin D helps the body absorb calcium and keeps bones strong. Iron is essential for carrying oxygen in the blood. When levels drop, the effects build slowly.“These nutrients support the production of energy, strength in bones, functioning of the brain and the overall immune system, and any deficiencies in these nutrients will lead to symptoms of fatigue, weakness, poor concentration, frequent infections, and, if untreated, even cause long-term health-related issues,” says Dr Tandon.The body keeps adjusting until it cannot. That is when symptoms become visible, and often harder to reverse quickly.
These nutrients are essential for energy, immunity, and overall health.
Why even “healthy eaters” are falling short
There is a common belief that eating home-cooked food is enough. While it helps, it does not guarantee balance.A vegetarian diet, for instance, may lack Vitamin B12. Limited sun exposure affects Vitamin D, even in sunny countries like India. Iron absorption can also be reduced due to poor food combinations or underlying gut issues.Variousstudieshave also highlighted anemia as a major concern, especially among women.The gap is not just about what is eaten, but how and when it is eaten.
Small daily habits that make a real difference
Correcting deficiencies does not always begin with supplements. It starts with routine.“Balanced nutrition focuses on being well-rounded in your daily food and drink intake by including the following food groups: green leafy vegetables, fruits, dairy, eggs, lentils, and nuts,” Dr Tandon notes.He adds, “It is essential that you spend a minimum of 15-20 minutes outside in the sunlight each day to boost Vitamin D levels.”Simple shifts can help:These are not drastic changes. But done consistently, they rebuild what the body has been missing.
The danger of guessing and self-medicating
Supplements are often seen as a quick fix. But taking them without testing can do more harm than good.“Self-prescribing supplements without performing the necessary tests should be avoided,” Dr Tandon cautions.Too much iron can harm organs. Excess Vitamin D can lead to toxicity. The body needs balance, not overload. A simple blood test, guided by a doctor, remains the safest starting point.
Early symptoms are often ignored, making regular testing and simple daily habits crucial for prevention and recovery.
Prevention is simpler than cure
Deficiencies rarely appear overnight. They build quietly over months or even years. That is why early detection matters.“Some of the ways to make simple lifestyle changes that can create a positive impact are eating regularly, engaging in regular exercise and obtaining regular health check-ups.The key to preventing these common, yet frequently overlooked, deficiencies is recognizing them early enough and correcting them in a timely manner,” Dr Tandon explains.Health, in this case, is less about big decisions and more about small, repeated actions.Medical experts consultedThis article includes expert inputs shared with TOI Health by:Dr Chirag Tandon, Director – Internal Medicine, ShardaCare-Healthcity.Inputs were used to explain why deficiencies in Vitamin B12, Vitamin D, and iron are becoming increasingly common, and what daily dietary and lifestyle changes can help maintain healthy levels and prevent related health issues.
