What are the best kinds of supplements a 50-year old can take?

Supplements after 50: Vitamin d deficiency is an epidemic at all ages, so i recommend checking your 25-oh vitamin d level and supplementing accordingly. Women go into menopause at the average age of 52, so at that point cyclic bioidentical estrogen and Progesterone replacement would be necessary. Men lose 1% testosterone per year starting at the age of 30, so by age 50 a man could be deficient in testosterone.
