Can health supplements interfere with effectiveness of the Pill?

[ss_storm]

I seem to remember when I first went on the Pill (just the normal one, not the mini pill) that my doctor said something about not taking vitamin C supplements because it would affect how well the Pill works..I don't know if it's true or not, but I want to start taking some immune boosters (my mum keeps harping on about tissue salts and garlic & horseradish tablets). Is there anything that will affect my contraceptive? What would you recommend for helping to maintain a healthy immune system and fighting colds?

Talk to your chemist, yes some natural therapies & health supplements can effect the pill.
