Calcium alone or in combination with vitamin D reduces fracture risk by 12 percent in men and women 50 years and older (NNT = 63). 26 The Food and Nutrition Board at the Institute of Medicine has established a daily intake for calcium and vitamin D sufficient to maintain bone health and normal calcium metabolism in healthy persons. 27 The calcium intake in men older than 50 years is 1,200 mg. The vitamin D intake in men 51 to 70 years of age is 400 IU, and in men older than 70 years is 600 IU. However, the recommended intake for preventing osteoporotic fractures is at least 800 IU per day. 26 Most experts agree that the goal is to maintain serum 25-hydroxyvitamin D levels above 30 ng per mL ( nmol per L). 28
Hi Ali: Regarding the mint studies…I just saw this on Suppversity…regarding the difference between mints effects on male and female rats…..Spearmint (M. spicata): At least in women spearmint tea has been shown to increase estrogen and luteinizing hormone in the follicular phase of their menstrual cycle (Aktodgan. 2007). In a 2004 study that was conducted on male rodents, on the other hand, the daily administration of peppermint tea (M. spicata) for a period of 30days lead to significant increases in luteinizing and follicle stimulating hormone and increases in serum testosterone, yet with the serious downside of “extensive degenerative changes in the germinal epithelium and spermatogenesis arrest compared with the findings in the testicular biopsies of the control group” (Aktogan. 2003) interesting for sure!
