vitamins/ supplements to take for increased energy while Breastfeeding?

I’ve got two kids, my oldest being 1.5, in breastfeeding my youngest and have NO energy, or sex drive. I know this is normal and very common, but is there any thing I can take that’s safe while breastfeeding to increase my energy?

I think it was maca root i’ve heard to help with sex drive, but haven’t done much research to see if it’s safe or not! TIA
