25(OH)D Serum Levels Decline With Age Earlier in Women Than in Men and Less Efficiently Prevent Compensatory Hyperparathyroidism in Older Adults

Abstract

These findings suggest that the age-associated fall of serum 25(OH)D starts earlier in women than in men and that higher levels of 25(OH)D are required in older compared to younger persons to avoid the age-associated compensatory hyperparathyroidism.
