What are some excellent and safe natural laxatives apart from the habits of eating healthy, lots of water etc etc?

Magnesium: If you do not have underlying kidney dysfunction, magnesium can be of help. Since we often eat processed foods, it is not uncommon to have deficiencies in this important mineral. Renal disease, severe diarrhea, or anti-hypertensive drug therapy may deplete natural stores of this mineral. Sources include spinach, tofu, pumpkin seeds, kelp and others. Best wishes!
