Is it true that taking those Emergen-C packets or any other vitamin supplements can effect the effectiveness of your birth control pill?
Emergen-C packets and other vitamin supplement drinks have become popular recently because they provide vitamin C, which is an essential nutrient, and they taste pretty good! However, research is inconclusive on whether such large doses of vitamin C are necessary and how these doses interact with other medications, birth control included.
Emergen-C packets may be a good way to make sure you are getting the necessary vitamin C, but they contain very high doses; if you take the recommended 2 to 4 packets per day you could get more than 4000 times what your body needs! Too much of anything, even a healthy vitamin, might not be a good idea.
Very high doses of vitamins may interfere with the birth control pill, though research is limited in this area. Known interactions and reduced efficiency occur with St. John's Wort, an herbal supplement, but vitamins A, C, and potassium may also have effects. It is best to tell your health care provider about which vitamins (and what doses) you are taking so s/he can best manage your birth control regimen.
The pill has been has been associated with some vitamin deficiencies in women, most commonly B6, B12, C and folic acid, which is why some women are encouraged to take vitamin supplements or watch their dietary intake more carefully when taking birth control pills. An added bonus is that getting enough of B6 and B12 may help alleviate some side effects of the pill such as nausea and mood swings. Again, talking with a health care professional will help you manage vitamin intake without compromising the effectiveness of your birth control.
If you're still not feeling clear on how vitamins interact with the pill, it's not you; research in this area is inconclusive. In a nutshell, some vitamins and the birth control pill seem to interact, however vitamins in small doses should not influence the effectiveness of the pill. It's always a good idea to have a conversation with your health care provider and give the clearest possible picture.
Remember, vitamins are important, but too much of a good thing isn't always better.Alice!
