2 dates added to my breakfast also really help!

For me, 3-4 prunes daily are excellent to add to the diet.

Eating one kiwi helps me with constipation. And they taste good, too.

Yep, agree.

Chickpeas are the best help for constipation for me. Other than that, a tablespoon of Olive Oil before breakfast helps too.

Spinach causes bad constipation for me. Figs work great, but gave me cavities. So I found other ways to combat the problem, including exercise.
I used to enjoy ground golden flax in overnight oats with strawberries, but that is a time consuming routine. Pears, nectarines, avocado, and olive oil work for me, and of course certain magnesiums also work great. I never got constipated from cinnamon, the opposite, but it was with apples...apple crisp.

Found that daily psyllium and/or 2 kiwi fruit (with skins) does the trick!

Does anyone know if Magnesium Oxide is safe to take occasionally. It works for me when I take it but not sure of it’s safety.

Magnesium Oxide is the only thing that consistently works for me

The best thing I have ever found for constipation is rhubarb supplements. It is very gentle and works better than anything. Unfortunately it cannot be used on a continuing basis.

Thanks for sharing your experience. We've added information about rhubarb for constipation in the following section of our article: https://www.consumerlab.com/answers/supplements-that-cause-constipation/supplements-constipation/#rhubarb

I find that about 6-8 prunes daily works for me with very little flatulence.

Years ago, an octogenarian told me the same thing and he was right. I find that 4-5 prunes does it well. We buy non-sorbate California prunes at Trader Joe. Note: Prune juice does not contain the fiber of actual prunes.

Sunsweet Prune Juice is available "with pulp" i.e. fiber.

1 to 2 tablespoons of flax meal in my morning smoothie or on top of cereal helps me completely avoid constipation, and flax is so healthy.

I have been taking dextrin (soluble fiber) in my coffee and think it helps, though that's hardly a controlled study, especially as I eat a high-fiber diet anyway. Dextrin is widely sold in the US as Benefiber and is much more pleasant to use than psyllium -- dextrin is soluble, does not thicken, and and is almost tasteless (very slightly sweet). It would be great to see this option discussed in future CL coverage.

I use dextrin also, Walmart store brand. Much prefer it to psyllium. I, too, put it in coffee--can't tell it's there.

I'm predictably regular by taking Magnesium Glycinate -- 400 mg.

Bluma19811

Yes, I’ve been better since taking 400mg of Magnesium

Charlene20991

Is this a safe amount for daily usage over time? What time of day do you take your Magnesium Glycinate?
