I take one of these late at night to soften my bowel contents a little. I don't need it but it's insurance against being constipated. More than 500mg softens a bit much for me. Magnesium in this form may not be well absorbed but I do notice benefit from magnesium oxide that I don't get from other forms that I believe is from oxygen being released in the gut from the oxide - a bit more energy and clarity of mind.

Easy to take, giving the benefits we need

There are many Magnesium supplements to select from. I know from experience that Swanson is a trusted brand; a company from experience and research that I trust to provide quality in the supplements they produce. So why magnesium oxide... a leading gastroenterologist praised the benefits of magnesium and above all the many varieties he recommended mag. oxide as my best choice. To my surprise this one is not the easiest to find. So I was delighted to see that iHerb offers it and with the Swanson label.

Great product.

I like to take the higher dose of magnesium oxide. This is a good brand without a lot of fillers added. I wish it would come in larger quantities as does the 200 mg version.

Very good product!

Great quality product. The dosage of 500 mg works well for my needs and the capsule size is easy to swallow. I appreciate the simple ingredient list with no unnecessary additives. I noticed a clear benefit for digestion and regularity. Since it’s in capsule form, there is no taste, which is a big plus. Would buy again.

dont take too much or you will be on the toilet.

i bought these because people were saying they were absorbed more slowly than other versions touted as being very absorbable and that they gave good effects.However it was clear to me even after a few days that even taking 1000mg a day which would only yield 24mg of magnesium sent me to the toilet.At 500mg no problem but then that's only 12mg a day of magnesium being absorbed.ill update the review in the future if there are any changes.
