Vitamin D alone does little to protect bone health in postmenopausal women

Calcium or combination supplement reduces osteoporosis risk
While calcium supplements noticeably improved bone health in postmenopausal women, vitamin D supplements did not reduce bone turnover, according to a recent study accepted for publication in The Endocrine Societys Journal of Clinical Endocrinology & Metabolism (JCEM).
Bone turnover is the bodys natural process for breaking down old bone. In young people, the body forms enough new bone to replace what is lost. After age 30, however, bone mass in women begins to decline and the process speeds up after menopause. Osteoporosis develops when the body cannot replace bone as fast as it is broken down.
"Vitamin D and calcium interact to suppress bone turnover by decreasing parathyroid hormone levels," said the studys lead author, John Aloia, MD, of Winthrop University Hospital in Mineola, NY. "This can be beneficial in women who are vitamin D deficient. In women who already are receiving the recommended daily allowance of vitamin D, however, the study found there was no advantage to adding a vitamin D supplement."
The double-blind, placebo-controlled, parallel group, longitudinal factorial design study divided 159 postmenopausal women into four groups. One group received a combination of vitamin D and calcium, one was given 1,200 milligrams of calcium daily, one took 4,000 IU of vitamin D daily and the last group received placebos. To measure the effect supplements had on bone health, researchers measured bone turnover markers, such as parathyroid hormone levels in the blood, over the course of six months. In all, 120 women completed the study.
Researchers found a significant decline in bone turnover markers among women who were given daily calcium supplements. The vitamin D supplements did not have any effect on bone turnover markers, although the supplements did decrease parathyroid hormone levels.
"These findings suggest that vitamin D supplements over the recommended dietary allowance (RDA) do not protect bone health, whereas calcium supplements do have an effect," Aloia said. "Women do need to be cautious about the possibility of vascular side effects from too much calcium and should consult their physicians about whether their diet is adequate or whether they should take supplements at all."

When Being Infertile Women Can stink Macho Men - Much like the ads on TV, angel of Khayangan fall because men perfume smell. It turns without using any perfume women can notice the macho man. Why just the macho? Because women can smell men with high testosterone grades.
Unfortunately it does not have the ability at any time, but when he was at the top of fertility.preceding study has found that when she was fertile, women are more attracted to identify and masculine environment of men. For example, a deep voice or manly attitude.
The investigators checked how women choose founded on the stink of testosterone and cortisolgrades of men. The male participants in the study were granted a top to wear for 2 nights in astrip. At this time, the men are prohibited from utilising detergent, drinking alcoholic beverage,fuming, and consuming garlic, red onion, green chili meal, dairy dairy cheese and other spicynourishment.
After that, participants were inquired to sniff her socks damaged male participants and assess the sexiness of male odor on a scale of 1 to 10. feminine participants were furthermore inquiredto fill out questionnaires on menstrual cycle and hormonal contraceptive use. To assess the levels of testosterone and cortisol men, the investigators used saliva trials.
The outcome discovered that women who are at the most fertile stage of her menstrual cycle is more like the smell of men with high testosterone levels. The womens shirt worn consider macho man most joy and the most sexy. But the woman could not stink a rat hormone cortisol ortension hormones male.
"This is the realm of the contentious research. Several studies have shown that a womans menstrual cycle affect mate assortment. Lot afresh discovered no effect of menstrual cycle on the preferences of the women," said psychologist Wendy Wood of the University of south California, as reported by LiveScience.
This mens body odor scent influenced by chemicals called androstenol. Men make more of this chemical than women. Male testosterone levels are also affiliated with the output of this molecule. Therefore, it seems that the women in the study answered to a unclear odor cues.

Calcium supplements linked to longer lifespans in women

Calcium-rich diet and supplements provide similar benefits
Taking a calcium supplement of up to 1,000 mg per day can help women live longer, according to a study whose lead author was Lisa Langsetmo, a Ph.D. Research Associate at McGill University, and whose senior author was Prof. David Goltzman, Division of Endocrinology and Metabolism in the Department of Medicine of the Faculty of Medicine and researcher in the Musculoskeletal Disorders axis at the Research Institute of the McGill University Health Centre (RI-MUHC).Their findings are published in the Journal of Clinical Endocrinology & Metabolism (JCEM).
Calcium, an essential nutrient for bone health, is commonly found in dairy products as well as vitamins. Although calcium is an essential nutrient for bone health, past studies have linked calcium supplements to heart disease risk. The researchers, located at universities across the country, analyzed data from the large-scale Canadian Multicentre Osteoporosis Study (CaMos) seeking to determine whether calcium and vitamin D intake were associated with overall increased risk of death.
"We found that daily use of calcium supplements in women was associated with a lower risk of death, irrespective of cause," said the studys lead author, Prof. Goltzman, Director, Calcium Research Laboratory at McGill. "The benefit was seen for women who took doses of up to 1,000 mg per day, regardless of whether the supplement contained vitamin D."
The longitudinal study of participants living in or near 9 cities across Canada monitored the health of 9,033 Canadians between 1995 and 2007. During that period, 1,160 participants died. Although the data showed women who took calcium supplements had a lower mortality risk, there was no statistical benefit for men. The study found no conclusive evidence that vitamin D had an impact on mortality.
"Higher amounts of calcium were potentially linked to longer lifespans in women, regardless of the source of the calcium," says Goltzman. "In other words, the same benefits were seen when the calcium came from dairy foods, non-dairy foods or supplements."
