We all live a busy and hectic lifestyle, always rushing towards one thing from another. Keeping up with the fast-paced life comes with significant sacrifices, especially in the area of our diet and nutrition. Not everyone in India is fortunate to prepare and consume balanced meals, having appropriate proportions of vitamins, minerals, protein, carbohydrates, and fats, daily. Often, we tend to rely on ready-to-eat ingredients mixed with artificial colours, additives, and fillers, which make our food less nutritious.

As an antidote to such a less nutritious diet, health experts recommend taking daily supplements. But are these synthetic vitamin supplements effective in meeting our nutrient goals? The vitamin and supplement industry is a million-dollar business worldwide. The section has grown along with the increase in lifestyle-related diseases. However, before you decide to buy these supplements, how about you understand the essential vitamins for our body?

How Can You Ensure Regular Supply of these Essential Vitamins?

As you may know, people usually consume multivitamin supplements to combat deficiencies. However, consuming supplements is not entirely necessary. Instead, you can plan a balanced meal throughout the day that is rich in necessary vitamins and minerals. Eating plenty of fresh fruits, vegetables, dairy products, fish, and meat is a healthy and primary source of vitamins and minerals in food.

You can refer to the table above to know the good food sources of essential vitamins.

On the other hand, in case of pregnancy, restriction in diets, or specific health issues, you can consume fortified foods and supplements for providing complete nutrition to the body. Besides, if you do take multivitamin supplements, ensure to not exceed the maximum dose. Consuming more than the needed quantity of supplements can lead to severe health issues.

Talk to your doctor or nutritionist before taking any vitamin supplements.


This concludes that vitamins are an essential nutrient that primarily comes from a balanced diet. Each essential vitamin plays a vital role in maintaining health. Vitamin deficiencies can cause severe side effects and health issues in an individual.

Instead of relying on supplements, aim to get the necessary vitamins by consuming a nutrient-rich diet. Get in touch with your doctor immediately in case of overdose. Besides, contact your health insurance provider to check whether such situations are covered in your health insurance policy or not.
