What Is Calcium?
Calcium is the most abundant and vital mineral found in our body. It sustains the entire skeletal system and muscles, supports the functioning of the nervous system, and is an essential component of the circulatory system.
Without it, the fat-soluble vitamins A, D, E, and K do not get assimilated in your body. This imbalance triggers a chain of disorders and deficiencies – which could mean bad news.
Read on to find out more about the role of calcium and the foods that have it in plenty.
What Is The Role Of Calcium In Your Body?
Calcium has the following functions:
- Keeps the bones and teeth healthy and prevents osteoporosis.
- Helps in the smooth circulation of blood throughout your body.
- Ensures that the endocrine system runs without hassles.
- Maintains the muscles, tendons, and ligaments, which is important for flexibility.
- Chief component of cell signaling, transport, and communication.
- Essential for blood clotting.
- Activates most of the enzymes and hormones to their active forms.
- Assists the movement of sperm to the egg during fertilization.
- Reduces risks during pregnancy.
- Regulates the heart rate and hypertension.
- Controls cholesterol and lipid absorption in the intestines.
- Prevents and treats cancer.
- Helps in weight management.
Phew! That’s quite a lot of work for one mineral, don’t you agree?
For all these and other functions to be carried out regularly and accurately, there needs to be enough calcium in your body. So, how much is sufficient? And does the requirement vary with age, sex, and body weight? Scroll down for the answers.
How Much Of Calcium Do You Need?
Yes, you are right! The requirements change with age and sex.
AGE | MALE | FEMALE | PREGNANT | LACTATING |
---|---|---|---|---|
0–6 months* | 200 mg | 200 mg | ||
7–12 months* | 260 mg | 260 mg | ||
1–3 years | 700 mg | 700 mg | ||
4–8 years | 1,000 mg | 1,000 mg | ||

An average adult woman (19-50 years) has to take 1,000 mg of calcium daily, girls (14-18 years) need 1,300 mg, and older, post-menopausal women need about 1,200 mg.
The tolerable upper intake levels (UL) of a supplement are the highest amount that most people can take safely. For calcium, it is as given below:

You might now ask me a question – where do you get those high amounts of calcium from?
Very simple – from your diet! Calcium is freely available in a lot of fruits, vegetables, seeds, dairy products, and leaves. The key is to have these calcium-rich foods in the right proportions.
Want to know what those foods are? Let’s get started!
Top 11 Calcium-Rich Foods
Dairy Sources Rich In Calcium
1. Milk
Milk tops the list of calcium-rich foods and is one of the most common and cheapest sources of the mineral. A cup of whole milk has about 276 mg of calcium along with 249 IU of vitamin A and 97.6 IU of vitamin D.
Although it has 7.9 g of total fat, whole milk is your go-to for most calcium deficit cases.
There are many fortified options available in the market, such as:
- Non-soy milk (imitation): A cup contains 200 mg calcium, 495 IU vitamin A, and 4.9 g total fat.
