Although birth control pills have a whopping 99% success rate in preventing pregnancies, only if taken as directed, you need to keep in mind that certain supplements you take can get in the way on how well your pill is working.
St. John’s Wort is a popular herbal remedy to treat individuals with depression and sleep disorders. However, consuming it might take a toll on the effectiveness of hormonal contraceptives. It contains liver enzymes that quickly metabolises the medication in the body, hence reducing the effect of the pill.
Other supplements such as garlic pill, alfalfa, saw palmetto, or flaxseed could be the culprits of pill failure. Before you decide to go on the pill, find out about the supplements you take that might affect the efficacy of the pill.
