The Science of Vitamins and Nutrients: A Complete Guide

Why Vitamins and Nutrients Matter?

What if the secret to glowing skin, a healthy body, strong immunity, and endless energy isn’t hidden in fancy treatments but in the vitamins & nutrients you consume daily through your regular diet? Vitamins and nutrients are essential for good health. They support the overall well-being of the body by nourishing each cell, tissue, and every organ in our body.
Vitamins and nutrients play an important role in maintaining energy, immunity, a healthy body, perfect skin health, and the growth of the body. They are divided into two groups: macronutrients and micronutrients. While macronutrients consist of protein, fats, and carbohydrates that provide energy, micronutrients contain vitamins and minerals, which make sure that our body systems function properly. If you are deficient in vitamins & nutrients, you cannot even use your energy properly that you gain from your daily diet.
Have you ever thought about why vitamin & nutrient deficiency is widespread nowadays? Answer is today’s busy lifestyle, poor dietary habits, processed foods, and stress usually lead to nutritional gaps. Let's understand vitamins and nutrients in detail, like how they work, and how to meet our daily requirements.

Vitamins are categorized into:

As we know, vitamins and nutrients are natural compounds that are essential in small amounts to keep our body healthy & full of energy. They act as cofactor in enzymatic reactions, antioxidants, immune boosters, and regulators of metabolism. We have to take some vitamins through food or supplements, as the body can't synthesize some types of vitamins. They are classified based on how they are absorbed, stored, and eliminated by the body.
Broadly, vitamins are categorized into two types:
i) Fat-Soluble Vitamins
ii) Water-Soluble Vitamins
Let's discuss both types in detail.

i) Fat-Soluble Vitamins (A, D, E, K)

These types of vitamins can be absorbed along with dietary fat, and they can be stored in the liver and fatty tissues. The body doesn’t need them daily in large amounts, and if they accumulate in the body in excess lead to toxicity. They are also essential for dietary fats or oils for proper absorption.
Here is the list of Fat-Soluble Vitamins
● Vitamin A – It is an essential vitamin for vision, immune health, and skin repair.
● Vitamin D – helps to balance calcium absorption and strengthens bones.
● Vitamin E - contains anti oxidative properties, boosts immunity, and protects cells from damage.
● Vitamin K – plays a major role in blood clotting and promotes bone strength.
By eating foods like salmon, nuts, spinach, or fortified milk with a healthy fat source like olive oil, you can improve absorption of these vitamins.

ii) Water-Soluble Vitamins (Vitamin C and B-Complex Group)

Water-soluble vitamins dissolve in water, and they aren't stored in the body in major amounts. If we consume them in excess, then they are flushed out through urine. As they aren't stored in the body, their regular consumption becomes mandatory. You must consume them daily, unlike fat-soluble vitamins, which have a lower risk of toxicity, and their deficiencies can develop quickly if intake is insufficient.
Vitamin C – It is an essential vitamin which supports immunity, collagen production, and acts as a powerful antioxidant. It protects skin from free radicals effects & UV damage. Due to its antioxidant property, it can protect us from cancer also.
Vitamin B Complex – Vitamin B complex consists B1, B2, B3, B5, B6, B7, B9, and B12 vitamins which helps in energy production, nerve function, red blood cell formation, and DNA synthesis. This is a critical vitamin for our overall well being.
You can include fresh fruits, vegetables, and whole grains in your daily diet to maintain consistent levels of these vitamins and take their amazing benefits.
