How Much Calcium In 1 Litre Milk


How much calcium is in 1 litre of milk? Well, according to, who are the producers behind, there’s a lot! Just hang on, and let me take you through this article which will teach you the answer to this question…

One litre of milk can provide approximately 1200 mg of calcium, representing more than the daily requirement for calcium. Calcium in milk is in a bioavailable form and is readily absorbed. The absorption of calcium is enhanced by vitamin A and lactose.

Milk Nutrition 

The following nutrition information is provided by the USDA for 1 cup (8 ounces) of reduced fat (2%) milk.

  • Calories: 122
  • Fat: 4.6g
  • Sodium: 95mg
  • Carbohydrates: 12g
  • Fiber: 0g
  • Sugars: 12g
  • Protein: 8g
  • Calcium: 307mg


The sugar lactose provides all of the carbohydrates in milk. Some milk products also include added sugars. If you’re trying to cut back on added sugars, you may want to limit your intake of these sweetened dairy products. Chocolate milk, strawberry-flavored milk, and ice milk have between 10 and 18 grams of added sugar per serving.

Despite its carb content, the glycemic index and glycemic load of milk are low: 1 cup of 2% milk has a GI of 27 and a GL of 4.


Milk is marketed by its fat content, making it easier to choose between different percentages: Whole milk is 4% fat, nonfat milk is 0%, and you can also get either 1% or 2% reduced-fat milk. Over half of the fat in milk is saturated fat. One-quarter of the fat is monounsaturated fat and a minor amount is polyunsaturated fat.

Milk can be a good source of omega-3 fatty acids.2 However, breast milk and infant formula contain more of the fatty acids babies need, so children under 1 year old should not drink cow’s milk.


Milk is a good source of protein, with 8 grams per cup. Milk proteins contain all nine essential amino acids that humans need. Milk has 82% casein protein and 18% whey protein. These separate when milk coagulates, as is done to make cheese. These protein isolates are used in many other food products; look for “casein” and “whey” on food labels if you need to avoid dairy.

Vitamins and Minerals

Milk is a very good source of calcium, phosphorus, vitamin D, riboflavin, and vitamin B12. Additionally, milk in the U.S. is fortified with vitamin D. It is also a good source of selenium, potassium, pantothenic acid, thiamin, and zinc.

Health Benefits

The USDA recommends including dairy foods in your diet. Milk and other dairy products help boost your calcium, protein, and vitamin Dintake for strong bones and muscles. The USDA also recommends choosing dairy products without added sugars or sweeteners and those lower in fat.

Improves Bone Density

The calcium and vitamin D found in milk and other dairy products is important for bone health and strength, and may help prevent osteoporosis (a weakening of the bones that can cause fractures). Dairy product consumption in childhood and adolescence is linked to a lower risk of osteoporosis later in life.3

Lowers Hypertension Risk

A 2013 study of over 3,000 women found an association between low dairy intake and both osteoporosis and hypertension, or high blood pressure.4 A review study also found that supplemented calcium intake slightly reduces blood pressure in people without hypertension, indicating that it may play a protective role.

May Protect Against Cancer

Research about the role of calcium in reducing the risk of some cancers (including colorectal, ovarian, and breast) has been mixed. But overall, it seems likely that calcium, from supplements and from dairy sources, may offer some protection against these cancers.

Improves Muscle Mass and Performance

A 2013 study of elderly women (ages 70 to 85) found that those who consumed 2.2 or more daily servings of milk, yogurt, and cheese had improved body composition and physical performance, compared to those who ate 1.5 or fewer servings a day.7 In younger women, using milk as a recovery drink after resistance exercise led to greater muscle mass, strength gains, and fat loss.8

Helps Control Weight

A study of more than 18,000 women over 45 years old concluded that consuming dairy products may help prevent weight gain in women in this age group who start out at a normal weight.

Can calcium be harmful?

Some research suggests that high calcium intakes might increase the risk of heart disease and prostate cancer.

High levels of calcium in the blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease. However, high levels of calcium in the blood and urine are usually caused by a health condition such as high levels of parathyroid hormone or cancer, not by high calcium intakes.

The daily upper limits for calcium include intakes from all sources—food, beverages, and supplements—and are listed below.

Life Stage Upper Limit
Birth to 6 months 1,000 mg
Infants 7–12 months 1,500 mg
Children 1–8 years 2,500 mg
Children 9–18 years 3,000 mg
Adults 19–50 years 2,500 mg
Adults 51 years and older 2,000 mg
Pregnant and breastfeeding teens 3,000 mg
Pregnant and breastfeeding adults 2,500 mg

Does calcium interact with medications or other dietary supplements?

Calcium dietary supplements can interact or interfere with certain medicines, and some medicines can lower calcium levels in your body. Here are some examples:

  • Dolutegravir (Dovato, Tivicay) is a medicine to treat HIV. Taking calcium supplements at the same time as dolutegravir can lower blood levels of the medicine. To help avoid this interaction, take dolutegravir 2 hours before or 6 hours after taking calcium supplements.
  • Levothyroxine (Synthroid, Levoxyl, and others) is a thyroid hormone used to treat hypothyroidism and thyroid cancer. Levothyroxine is not absorbed well when taken within 4 hours of taking a calcium carbonate supplement.
  • Lithium (Eskalith, Lithobid) is used to treat bipolar disorder. Long-term use of lithium, or taking lithium together with calcium supplements, can lead to abnormally high levels of calcium in your blood.
  • Quinolone antibiotics (examples are ciprofloxacin [Cipro], gemifloxacin [Factive], and moxifloxacin [Avelox]) are not absorbed well when taken within 2 hours of taking a calcium supplement.

Tell your doctor, pharmacist, and other healthcare providers about any dietary supplements and prescription or over-the-counter medicines you take. They can tell you if the dietary supplements might interact with your medicines or if the medicines might interfere with how your body absorbs, uses, or breaks down nutrients such as calcium.

Calcium and Healthful Eating

People should get most of their nutrients from food and beverages, according to the federal government’s Dietary Guidelines for Americans. Foods contain vitamins, minerals, dietary fiber, and other components that benefit health. In some cases, fortified foods and dietary supplements are useful when it is not possible to meet needs for one or more nutrients (e.g., during specific life stages such as pregnancy).

The amount of calcium in milk and milk beverages is generally determined using atomic absorption spectroscopy (AA) or inductively coupled plasma atomic emission spectroscopy (ICP). Ion chromatography (IC) using acidic elute can also measure total calcium amount regardless of the form in which the calcium exists. Alternatively, the calcium ion selective electrode method measures the amount of free calcium ions. In addition, chelate titration allows measurement of free calcium ions and part of the calcium bound to other substances.
However, by ionizing protein-bound calcium using an acidizing pretreatment,, the calcium ion-selective electrode method (LAQUAtwin Ca2+) can be used to measure the total amount of calcium.

The following gives an explanation of this based on empirical data—measured by a variety of methods—on the calcium content of milk and milk beverages.For each type of sample, the following table shows the labeled value, together with the values measured by various methods. The diagram below shows the correlation between LAQUAtwin Ca2+ data and that from other methods for a pre-treated sample. Without the need for a large measurement system, LAQUAtwin Ca2+ produced values of total calcium amount that are approximately equal to those obtained by other methods.

Pretreatment of the lactic drink sample consisted of adjustment to a pH of around 2, followed by readjustment to a pH of 4 prior to measurement being carried out.

Pretreatment procedure (for milk)

  1. Place 5 mL of sample solution in a 100 mL beaker.
  2. In the case of milk, add 50 to 60 μL of 5M hydrochloric acid to the sample in step 1.
  3. Use LAQUAtwin to confirm that the sample has a pH of 4.3 to 4.6. Return the sample solution to the beaker.
  4. Add 45 mL of water to the sample created in step 2, thereby diluting it tenfold.
  5. Wait for a few minutes to allow the protein to precipitate then collect a sample of the supernatant solution.

Pretreatment procedure (for milk beverages such as lactic drinks)

  1. Place 5 mL of sample solution in a 100 mL beaker.
  2. Add 100 μL of 5M hydrochloric acid to the sample and confirm that it has a pH of around 2 using LAQUAtwin. Return the sample solution to the beaker.
  3. Add 45 mL of water to the sample created in step 2, thereby diluting it tenfold.
  4. Add approximately 0.05 g of tris-hydroxy-aminomethane to the solution and confirm that its pH has changed to around 4.3 to 4.6 using LAQUAtwin pH.
  5. Wait for a few minutes to allow the protein to precipitate (sediments may not be visible to the naked eye) then collect a sample of the supernatant solution.
