Vitamins and nexplanon

Hi everyone. So for the last 3 months I have been hitting the gym super hard and I am wanting to better my health. I don’t take any type of vitamins but I am wanting to start because I know that will help me in the gym. I’m a little nervous though because I have heard that a lot of things can effect your birth control. I am currently on nexplanon implant. Other than St. John’s wort, is there any kind of vitamin that will negatively effect my birth control. I am wanting to start taking b vitamins, fish oil, c and d vitamins and iron.
