Food You CAN Eat the Day Prior to the Test

(from 8am – 8pm the day prior)

As we age our hormone levels change which can cause a variety of unpleasant symptoms.  Bioidentical hormone replacement therapy (BHRT) replenishes the hormones your body needs to function to its fullest. BHRT utilizes medications that have the same chemical formula as those made naturally in the body. They are referred to as “bio-identical” hormones and are chemically identical to human hormones. An imbalance in hormones can cause fatigue, sleep problems, depression, low sex drive and more.
