Hi I had a doubt about taking opti women which is a multi v for females while taking birth control pills, do you know if this two products can interfere with each other and cause any type of health issues?
They will not interfere in any way. Vitamins and minerals will not effect the way birth control works. They are perfectly safe to use together.
A women can use all the same supplements that men can use. The only exception is hormonal products like pro-hormones. Women do not want to use anything hormonal because it can cause emasculating side effects like facial hair growth, clit enlargement and voice deepening.
These are two completely different classes of drugs, which do not interact in any way - neither positively, nor negatively. Therefore, it is absolutely ok to use them both, and I would even say that it is very beneficial, since some extra vitamins will always come in handy.
