Women's health after 40, and what the research actually supports
Interpreting T-scores, calcium absorption by form, the roles of vitamin D and K2, and the calcium-cardiovascular debate.
A vitamin D result of 25 ng/mL is sufficient under one standard and insufficient under another. Both standards were set by major expert bodies, using largely the same evidence. Understanding why they differ explains more than the number itself does. Two thresholds, one evidence base The two positions are well documented because the bodies holding … Read more
