Caffeine is one of those ingredients that most people do not consider to be a drug. Yet this chemical is a powerful stimulant. It can be found in many drinks like coffee and soft drinks, and now you can even buy bottled water laced with caffeine. Caffeine increases your blood flow and can make you feel wide awake and alert. What may surprise you about caffeine is that some studies have linked it to an increased risk of miscarriage.

Since there is no recommended daily allowance (RDA) of caffeine it's hard to set a limit. Most practitioners tread lightly here and will tell you that it's okay to have one cup a day of your favorite caffeinated product. But if you're trying to become pregnant and want the best start for your pregnancy, skip the caffeine all together! Why even worry with a slight risk?
