What supplements should someone on birth control pills take?

The birth control pills do deplete things. They create issues that could create issues with your bile. I wouldn't necessarily take a vitamin while you're taking birth control. I would just kind of see if you're deficient in anything, because if your diet is the healthy version of the ketogenic diet, then you're probably going to be okay. But I will say that one issue that I've seen in the past with birth control pills is that does mess with the gallbladder. And sometimes then you can't absorb from the diet, the fat soluble nutrients like the vitamin A, D, E, K1, K2.
