Don't buy supplements that have additional additives, dyes, binders, fillers, and preservatives. Check expiration date and make sure that you're getting fresh ones. Those that have a USP designation are generally better than those without. I am partial to those backed by reputable scientists, doctors, and manufacturers. Lately perimenopause and menopause have received a great deal of attention in the media.
Some specific foods are helpful for both problems also.
Soy products, for example, can temper hot flashes and relieve vaginal dryness and can also lower blood cholesterol, control blood clotting and may increase the flexibility of blood vessels. These are just a few examples of the similarities. It's great to know that some basic dietary changes can cover so many different functions of the body. I like how you give women many natural options for heart protection. There are numerous natural heart protectors that have been shown by scientific study to be as effective as estrogen without the attendant side-effects that plague so many women.
