MiraFAST™ and MiraLAX® are both laxative products that work naturally with your body to relieve occasional constipation. However, they have different active ingredients.

MiraFAST™ is a saline laxative that is designed for quicker, gentle relief. It contains magnesium hydroxide, which provides cramp-free, stimulant-free relief in 30 minutes to 6 hours. It comes in a tasty, mixed berry-flavored soft chew.

MiraLAX® is a gentle, osmotic laxative that works to relieve occasional constipation by drawing water into the intestines to soften and ease stool. It contains polyethylene glycol 3350 (PEG), which generally helps to produce a bowel movement in 1 to 3 days. It comes in a powder form that can dissolve in any hot or cold beverage and does not cause harsh side effects such as gas, bloating, cramping or sudden urgency.

Take MiraLAX® if you prefer a more gradual approach to gentle, occasional constipation relief, and prefer a powder form that you can mix into any hot or cold beverage. MiraLAX® generally produces a bowel movement in 1 to 3 days.
