Your A-Z Guide on All Essentials Vitamins and Minerals Your Body Needs

Apart from the macronutrients we get from food, our body also requires a list of micronutrients for smooth functioning and to keep us healthy. These micronutrients are not produced in our bodies and need to be derived from our diet or supplements.

If we regularly consume a balanced diet that consists of plenty of fruits, vegetables, whole grains, pulses, and healthy fats and protein, we can meet the requirement without any wholefood multivitamin supplement. But owing to our busy and modern lifestyle, it may not always be possible. Turning to a reliable supplement source may be a good option in this case.

Vitamins are necessary for energy production, immunity, normal cell function, growth, and development. Whereas minerals are important for bone health, healing, and utilization of nutrients in the body.

In this guide, we’ll talk about the important role of vitamins and mineral required for our day-to-day functioning and how can we acquire them.

Here’s a list of vitamins and minerals we require on a daily basis:

  • Vitamin A
  • Vitamin B Complex
  • Vitamin C
  • Vitamin D
  • Vitamin E
  • Vitamin K
  • Calcium
  • Iodine
  • Iron

1. Vitamin A

Vitamin A, most commonly known as retinol, has recently been a hot topic in the skincare industry. It is a fat-soluble Vitamin that is present in a lot of foods and plays an integral part in helping

- the body naturally defend against illness and infection aka keeping the immune system functioning properly,

Fun fact: It is known as retinol owing to the pigment it produces in the retina of the eye.

Sources of Vitamin A

Vitamin A is found in plant as well as animal foods.
For animal sources - beef liver, oily fish, cheese, dairy foods, and eggs are good sources of the vitamin. When it comes to plant-based sources, vegetables containing high levels of beta-carotene are deemed great sources of Vitamin A. Think anything from broccoli, beetroots, and lettuce, to the celebrated carrots. Not only do they improve your night vision, but also help in the conversion of retinol for all your skin needs.

Symptoms of Vitamin A deficiency

  • Night blindness

There is more than one type of Vitamin B. It includes Vitamin B1, B2, B3. B6, B7, B12, pantothenic acid, folate, and folic acid. These Vitamins are essential for

  • breaking down carbohydrates
  • delivering nutrients to the body.

Every type of B Vitamin has its own function and together they’re all known as Vitamin B complex.

Sources of Vitamin B and folic acid

Animal sources of Vitamin B complex include milk, cheese, eggs, red meat, fish such as tuna and salmon, and even shellfish. For plant-based sources, dark green leafy vegetables like spinach and kale are great sources. Even whole grains, beans like kidney beans and chickpeas, tempeh, and fruits like banana and watermelon are rich in Vitamin B complex. An all-rounder vitamin B12 supplement can also aid in the proper functioning of your body.

Symptoms of Vitamin B deficiency

If you ensure you eat a balanced diet on a daily basis, most of your food will give your body the necessary amount of Vitamin B. But certain medications or diets can make you deficient. Here are the symptoms your body might exhibit in those cases:

  • Wounds healing
  • boosts our immune system.

The body also requires Vitamin C to stimulate the biosynthesis of collagen. Collagen is a vital component in tissues like tendons, ligaments, skin, gut, etc. Vitamin C also helps the body make several hormones and chemical messengers that are used in the brain and nerves.

Sources of Vitamin C

It is common knowledge that all citrus fruits contain sufficient levels of Vitamin C. You can also opt for natural Vitamin C tablets if you aren’t able to meet the requirement through diet alone. Here are a few dietary sources:

Vitamin D has the following benefits :

  • aids in the regulation of calcium and phosphate in the body.
  • controls infections
  • reduces inflammation.
  • helps in regulating mood and reduce signs of depression.
  • Its fat-soluble property also helps it play a role in regulating kidney functioning and treating kidney disease.

Sources of Vitamin D

The best source of Vitamin D is sunlight as the body creates vitamin D from direct exposure to sunlight. However, the timing of the exposure also plays a very important role. In India, sun exposure from 11 am to 2 pm promotes Vitamin D production in the skin.

Natural sources of vitamin D can also be taken via wholefood multivitamin supplements. Here are some other food sources of vitamin D.

  • acts like a vasodilator to keep blood from clotting and ensures smoother blood flow.
  • Plays a role in helping cells carry out their important functions.

Vitamin E is a group of compounds easily found in a wide variety of fatty foods. These include:

6. Vitamin K

Vitamin K helps the liver produce proteins that help the blood coagulate. In simple words, it is what helps prevent excessive internal and external bleeding.

Sources of Vitamin K

  • Green leafy vegetables like lettuce, cabbage, spinach, and kale

  • Longer time for blood clotting
  • Excessive bleeding during menstruation
  • Hemorrhaging

Vitamin Toxicity

Vitamin toxicity occurs when there are high levels of a vitamin in the body. It is primarily caused by fat-soluble vitamins like Vitamin A and Vitamin D since they are stored in the body longer than water-soluble vitamins. It can be caused by high doses of supplements or a large intake of highly fortified foods. It can easily be avoided by monitoring your intake of wholefood multivitamin supplements based on the level of deficiency or gaps in your diet.


Calcium is widely associated with healthy bones and teeth, but not many know that calcium also plays a role in blood clotting, just like Vitamin K.

  • Easy fracturing of bones/weaker bones


The body needs the mineral iodine to make thyroid hormones. These hormones further control the body’s metabolism and other important functions.
