Types Functions Sources and Deficiency Diseases of Vitamins and Minerals
Vitamins and minerals are crucial nutrients that keep our bodies energised, our immune systems strong, and our minds sharp. Even though they often get grouped together, there is a key vitamins and minerals difference that you should know: vitamins are organic substances derived from living organisms, while minerals are inorganic elements sourced from the earth and water. Understanding both, as well as consulting a clear vitamins chart, helps you plan your diet wisely and prevent deficiencies.
What Makes Vitamins so Important?
Vitamins are organic compounds that our bodies require in small amounts for normal growth, development, and overall health maintenance. Although there are 13 essential vitamins in total, our bodies can only produce two of them—Vitamin D and Vitamin B3—in limited quantities. For the rest, we rely on foods and sometimes vitamins and minerals tablets or vitamins and minerals supplements.
Let’s take a look at the vitamins chart that outlines their types, key sources, and deficiency diseases.
Note: Overconsumption of some vitamins (especially fat-soluble ones) can be harmful, so always follow recommended dosages if using vitamins and minerals tablets.
Minerals: The Other Half of the Story
Minerals are inorganic elements absorbed by plants from soil and water, eventually making their way into our food chain. Although we need them in varying amounts, each mineral plays an essential role in supporting the vitamins and minerals function in our bodies. Consuming adequate amounts of vitamins and minerals in food ensures you maintain strong bones, balanced fluid levels, and a well-regulated metabolism. Below is a concise vitamins and minerals list of some key minerals, their sources, and primary functions.
Tip: Vitamins and minerals supplements can be useful if your diet lacks certain nutrients, but always consult a healthcare provider before starting any regimen.

Fat-Soluble vs. Water-Soluble Vitamins
Fat-Soluble Vitamins (A, D, E, K): These are stored in the body’s fatty tissues and liver. They are absorbed more efficiently when consumed with dietary fats.
Water-soluble vitamins (B-complex and C): These are not stored in large quantities, so your body needs regular replenishment through vitamins and minerals in food sources or supplements.
Exploring the Vitamins and Minerals Difference
Organic vs. Inorganic: Vitamins are organic compounds that can be broken down by heat, air, or acid. Minerals are inorganic and maintain their chemical structure.
Storage: Excess fat-soluble vitamins can accumulate in the body, while most minerals are excreted if they are not needed.
Sources: Vitamins often come from plant and animal foods. Minerals originate from soil and water, later absorbed by plants or consumed by animals.
Balancing Nutrients for Optimal Health
Synergy Matters: Iron absorption is boosted by Vitamin C, while Calcium pairs well with Vitamin D to strengthen bones.
Watch Your Intake: Both deficiencies and excesses can cause health issues. For example, too little iodine can lead to goitre, whereas too much Vitamin A might cause toxicity.
When Tablets Help: In certain life stages (e.g., pregnancy or old age) or specific health conditions, taking vitamins and minerals tablets can help meet daily requirements.
Supplements for Special Cases: Certain diets (vegan, vegetarian) or malabsorption conditions may necessitate vitamins and minerals supplements to prevent deficiencies.

FAQs on Vitamins and Minerals in Human Nutrition
1. What are vitamins and minerals?
Vitamins and minerals are essential micronutrients required in small amounts for normal growth, metabolism, and overall body function. Unlike carbohydrates, proteins, and fats, they do not provide energy but help regulate vital biological processes.
- Vitamins are organic compounds made by living organisms.
- Minerals are inorganic elements obtained from soil and water through food.
- Both are crucial for enzyme activity, tissue repair, immunity, and maintaining homeostasis.
2. What is the difference between vitamins and minerals?
The main difference between vitamins and minerals is that vitamins are organic compounds while minerals are inorganic elements.
- Vitamins can be broken down by heat, light, or air.
- Minerals retain their chemical structure and are not destroyed by cooking.
- Vitamins are classified as fat-soluble or water-soluble, whereas minerals are grouped as macrominerals and trace elements.
3. What are the types of vitamins?
Vitamins are classified into fat-soluble and water-soluble types based on how they are absorbed and stored in the body.
- Fat-soluble vitamins: A, D, E, and K (stored in liver and fatty tissues).
- Water-soluble vitamins: Vitamin C and B-complex (B1, B2, B3, B5, B6, B7, B9, B12), not stored in large amounts and require regular intake.
4. What are macrominerals and trace minerals?
Macrominerals and trace minerals are categories of dietary minerals based on the amount required by the body.
- Macrominerals: Needed in larger amounts (e.g., calcium, potassium, sodium, magnesium, phosphorus).
- Trace minerals: Required in small quantities (e.g., iron, zinc, iodine, selenium).
5. What is the function of vitamins in the body?
Vitamins primarily function as coenzymes or regulators of metabolic reactions in the body.
- Support energy metabolism (B-complex vitamins).
- Maintain immune function (vitamins A, C, D).
- Help in blood clotting (vitamin K).
- Promote cell growth and repair.
6. What is the role of minerals in the human body?
Minerals play structural and regulatory roles in maintaining normal body function.
- Calcium and phosphorus form bones and teeth.
- Iron is part of hemoglobin for oxygen transport.
- Sodium and potassium regulate nerve impulses and fluid balance.
- Zinc supports enzyme activity and immunity.
7. Why are vitamins and minerals important for growth and development?
Vitamins and minerals are crucial for growth and development because they regulate cell division, tissue formation, and metabolic pathways.
- Vitamin D and calcium ensure proper bone growth.
- Iron supports brain development and oxygen supply.
- Folate (Vitamin B9) is vital for DNA synthesis and cell division.
8. What are common deficiency diseases caused by lack of vitamins?
Common vitamin deficiency diseases occur when the body lacks specific essential vitamins.
- Scurvy: Caused by vitamin C deficiency.
- Rickets: Due to vitamin D deficiency in children.
- Night blindness: Caused by vitamin A deficiency.
- Beriberi: Results from vitamin B1 deficiency.
9. Can you get enough vitamins and minerals from food alone?
Most people can obtain adequate vitamins and minerals through a balanced and varied diet.
- Fruits and vegetables provide vitamins A, C, and folate.
- Dairy products supply calcium and vitamin D.
- Meat and legumes provide iron and zinc.
10. What happens if you consume too many vitamins or minerals?
Excess intake of certain vitamins and minerals can cause toxicity or adverse health effects.
- High doses of fat-soluble vitamins (A, D, E, K) can accumulate in the body.
- Too much iron can damage organs.
- Excess sodium may increase blood pressure.
