I (Amazon prime member) see the 30%. But only as a "Subscribe and Save" option.

What does it mean when it says 400mg and 60mg at MG? Are you getting 400mg or 60mg?

From the Q&A on the item page:

Q. What is the difference between 60 mg and 400mg magnesium glycinate?
A. There is 400mg of Magnesium Glycinate in each capsule. By definition magnesium glycinate contains approx 60mg of Elemental Magnesium and 340mg Glycine. Hence the name "Magnesium Glycinate".


FYI, I use NOW Magnesium Glycinate with BioPerine which has 100mg elemental magnesium per tablet and the BioPerine (black pepper) aids in absorption. Considering that, at $15 per 180ct bottle, it is a better buy than this. Also, Now is a highly reputable family owned company.

Most cheap magnesium glycinate raw material is sourced from China. Not sure why you're getting thumbs down here. The globally sourced ingredients part is China in this case. That being said it would be most of the market and the Chinese raw material makers typically used are quality. Where you should have pause is when the supplements are made in China because the testing of those brands is questionable at best. Unfortunately, the Chinese supplement brands just fake made in America on their listings.

I bought this at full price last year. Whenever I have trouble sleeping, I take one pill an hour before bed, and it helps me get a deep, restful sleep.
If you feel like this brand isn't reliable, you can always buy a different one at Costco. I think it's around $16.99 a bottle.

Seems to me that most good quality magnesium pills are around 100mg of elemental magnesium. The pills in this Slickdeal are only 60mg, which is barely half. Plus they recommend only 1 pill per day, while other brands recommend 200mg per day. The FDA recommends up to 420mg of magnesium per day (depending on age, gender, pregnancy, etc), preferably a good portion of that from a healthy diet.
