However, in an earlier research study it was found that optimizing bone mass in teens and early adulthood averts low bone density and osteoporosis in later parts of life. Moreover, using oral contraceptives can decrease bone density too.

According to the experts at the Purdue, it is interesting to know that in United States, out of every 10 women, eight use oral contraceptives at some time during the years in which peak bone mass is developing. Also, this loss can be easily supported by using calcium in optimum level.

If we look at the figures provided by the National Academy of Sciences, the recommended dietary allowance of calcium for women age 19 to 50 is 1,000 milligrams a day. In addition, calcium’s recommended daily allowance for adolescents especially women aged from 9 to 18 is about 1,300 milligrams.

To prove the point of study, around 135 oral contraceptive users and non-users between the ages of 18 and 30 were taken as research items. Propel were divided into basic three groups to receive one of three diets: control (less than 800 mg calcium a day), medium dairy (1,000-1,100 mg calcium a day) and high dairy (1,200-1,300 mg calcium a day).

After an year of observation, women using oral contraceptives and consuming the medium- or high-dairy diet gained better bone mineral density in their bodies especially at hips and spines compared to the low-dairy group.

Interestingly, it is found that women who are using oral contraceptives in their peak bone-development years can avert their risk of osteoporosis by nearly 3 percent to 10 percent by consuming adequate amount of calcium in their diets.
