What are the best vitamins and minerals for adults or elderly?

We all know our body needs nutrients to function properly and smoothly. Nutrients include minerals, vitamins, carbohydrates, fats, and proteins. With the increase in age, these nutrients start to deplete in our body, especially minerals and vitamins. While carbohydrates, protein, and fats can be easily taken through food, the minerals and vitamins are somehow difficult to consume as their intake is measured in milligram and microgram.

Here is an insight into all the minerals and vitamins that a normal adult body needs.

What are minerals?

How to choose a right multivitamins supplements

Minerals are a part of nutrients that are required for proper maintenance of the body. Minerals include phosphorus, potassium, calcium, iron, phosphorus, manganese, magnesium. These minerals are required by our body in a small amount and taking a higher dose than required can have a negative effect on our body mechanism.

Some minerals which are important for adults and elderly are as follows:


It is a very important mineral which constitutes up to 1 percent of our body weight. About 85  percent of the total phosphorus is found in skeleton and teeth. Rest 15 percent is present in our soft tissues and body fluids. It is very important as it is responsible for maintaining proper acid-base balance in our body and is a major component of ATP, the energy producing unit of our body.

Amount of phosphorus required in male and female bodies are different. An adult male should consume 1300mg/day while an adult female should consume 1mg/day.

Phosphorus along with calcium helps in keeping our bones, teeth and nervous system healthy. Although the deficiency of phosphorus is rare, in case it happens it leads to excessive weakness. Phosphorus can be found in dairy products, fish, and meat.


Calcium is basically required by human body for healthy bones. If there is not sufficient calcium in our body, it results in osteoporosis, a condition in which pores in our bones become large. Another condition that may arise due to calcium deficiency is osteomalacia that is softening of bones, it makes bones prone to fracture.

Adults need 1200-1400 mg calcium per day. The main source of calcium is dairy products. People who allergic to dairy products or those who have an eating disorder are at high risk of calcium deficiency.


Iron is a major component of blood hemoglobin. Hemoglobin is a substance present in red blood cell(RBC) which helps in transportation of oxygen in our body. The most common symptom of iron deficiency is fatigue. The major issue that you can face due to iron deficiency, especially females is anemia. Inadequate intake of iron by adults can lead to weakness and pale skin.

Some common sources of iron are leafy green vegetables, other green vegetables, and jaggery.
