What nutrients can help reduce postmenopausal bone loss?
After menopause, bone breakdown outpaces the building of new bone, which results in a gradual loss of bone mass and puts women at an increased risk of osteoporosis. This is largely because of the sharp drop in oestrogen that occurs, a hormone that has a protective effect on bones throughout a woman’s life. It is estimated that the average woman loses up to 10% of her bone mass in the first five years after menopause, which can have an effect on her bone health and strength over time. Fortunately, there are steps a woman can take to support her bone health, slow the rate of postmenopausal bone loss and protect bones from becoming weak and brittle.
1. Get enough calcium every day
Calcium is a major structural component of bone tissue and is required for the maintenance of strong, healthy bones. A diet insufficient in calcium can lead to osteoporosis in later life. Women over the age of 51 require at least 1300mg of calcium a day to support bone health and offset their bone losses, which can be achieved by consuming good dietary sources of calcium such as milk and milk products, leafy green vegetables or canned sardines and salmon and/or taking a calcium supplement.
2. Ensure adequate vitamin D
Vitamin D is also essential for the development and maintenance of bones as it helps the body efficiently absorb and utilise calcium from the food we eat. Vitamin D is synthesized in the skin when it is exposed to ultraviolet (UV) radiation from sunlight and is also available in some foods and supplements. Supplemental vitamin D becomes especially important for those who avoid the sun, have naturally dark skin, wear concealing clothing or are older whereby the capacity for skin synthesis of vitamin D is reduced.
3. Take a vitamin K2 supplement
Vitamin K plays an important role in maintaining bone health and strength as it is required for the activity of osteocalcin, a protein that supports the function of calcium in bone development. Supplementation of vitamin K2 has been found to decrease bone loss in postmenopausal women. This unique form of vitamin K remains in the blood longer than vitamin K1, which is the type commonly found in supplements, and may therefore have extended availability for use by the body. Vitamin K2 can be found in some foods including aged cheeses, animal livers and the Japanese dish natto (fermented soybeans), but it may be difficult to get enough from a typical western diet.
Ostelin Cal¬DK2 contains a combination of these three important nutrients and may be beneficial for postmenopausal women or those reaching menopausal age, who wish to protect their bones and help reduce the rate of bone loss.
