Well, you don't want to replace estrogen, but maintain healthy estrogen levels. Estrogen can't be replaced. There's natural estrogen and unnatural estrogen. I would recommend that you perform the Full Body Cleanse followed by The Female Cleanse. After these kits, a good formula would be Female Hormonal as well as the Female Health Tea. We also have a good article entitled "Female Hormonal Replacement Therapy?" for your memory problems, I suggest Brain Booster and Oxy-Drops. Don't forget to change your diet and eat more natural and healthy foods too (i.e. Fruits and veggies).
