digestion problems

I've experienced constipation for the last 2 weeks, i am doing a candida diet and have been oil pulling for 3 weeks. I thought the oil pulling would help me with my bowel movements?
I do enjoy oil pulling and my mood is definately lighter and my teeth feel cleaner too, but it hasn't helped with my digestion :(
I'm wondering as i've heard oil pulling can lower magnesium levels, which are needed for bowel movements ?
