I have suffered from constipation for years and have used many products including the best digestive enzymes and acidophillus available - I am also a nutritionist so I eat well and take heaps of the best supplements. I've also had colonics and massage to help.
The thing that has worked wonders for me without question is kiwi fruit. first thing on an empty stomach I eat 3 kiwi or blend them with another fruit and some chia seeds, and I have absolute success every time.
I think kiwi have the right ph for your gut health, are full of enzymes and also are slippery.
Try this and share!
I used to constipation till a doctor gave me this piece of advice: eat kiwis first thing in the morning (maybe better start with just one...). It worked wonders. After a while any fruit worked, even bananas and my intestines became so regular that I didn't even need to do a thing anymore. Now I started to use coconut oil things have changed but they will go back to normal I hope!
