Please let's keep government regulation where they are now. People taking supplements should research each product. Support the companies that are transparent and do third party testing and show those test results along with product information. People buying only from reputable companies will "police" the market and bad companies simply will get no business. Consumers can do this without government further involvement if they wish to put in the effort.

Quote from howdydo :
Something doesn't seem right. It claims one capsule contains 200 mg of mag. glycinate when other popular brands usually require 2 capsules to equal 200 mg and those capsules are already pretty huge. To fit 200 mg into one capsule the size would have to be twice the size of the other brands, way larger than a person could comfortably swallow. But the pics show these to be about the same size as one 100 mg capsule.
Maybe less filler, or less gylcine, i take my glycine seperately, a daily 3 gram dose is a lot powder

Some facts:
  1. Amazon now requires all supplements to go through independent testing at their approved labs, with results sent directly to Amazon.
  2. Magnesium glycinate is only about 14% actual magnesium by weight. The rest is the glycine + manufacturing fillers needed.
  3. To get 200mg of magnesium content, you need roughly 1400mg of 'magnesium glycinate'.
  4. A "00" capsule of pure magnesium glycinate should hold about 700-800mg of powder. A "000" capsule might take around 1500mg if you're lucky, but "000" capsules are somewhat rarer since they are really big and most production lines aren't set up for it.
I'll leave out a bunch of technical info that's not necessary.

Most magnesium supplements are a borderline scam, usually having a very low dose per capsule or using oxide which is poorly absorbed. If you want a true 200mg per serving, find tablets. There are a few out there, and you really have to look, that make 200mg PER TABLET magnesium glycinate products. The tablets will weigh about 1.6-1.7g each.

If someone has this and can weigh a few capsules, we will know for sure.

edit: after someone posted some great pics for size, I'd say they likely are '000' capsules and probably do have, or close to, 200mg each capsule. Good deal for this price. Tablets are still the better option for getting 200mg glycinate in 1.
The end is nigh.

False.

Go to any gas station and look at all the tiny plastic bottles and pills.

They buy the package and ingredients separately from China and fill them with whatever they want.

18 year olds don't have the life experience to know that stuff can be highly addictive or dangerous depending on what is added.

Those young people all have a phone attached to them. Can easily look for information on anything these days. Like was said, one needs to put in the effort. Take the responsibility for one's own actions. The government does not have a great record on health care. Personally I do not want the government involved in regulating every little aspect of life.

That would be the ideal scenario, but take this example here. This product claims to be 3rd party tested, but it's not. It has no stamps on the bottle from USP, NSF, or informed choice. So they're lying about the inspection....now what else are they lying about? If we could trust the labels, then yes, allow consumers to make their own choices. But therein lies the problem, hence the required (at least basic) regulation that's needed.

If anyone is still following, this is relevant to future Magnesium deals also so I'll comment anyway.

This product is confirmed, using 00 capsules 900mg avg filled, a typical Magnesium Oxide buffered Magnesium Glycinate.

200mg elemental Magnesium IS correct, BUT it is NOT 100% Magnesium Glycinate and has an unknown percentage of Magnesium Oxide to makeup the difference.

Using simple best-case scenario assumptions, it's likely 50/50 - 100mg comes from Magnesium Glycinate and 100mg comes from Magnesium Oxide per capsule.


TLDR;
Consider this a 100mg (AT BEST) Magnesium Glycinate capsule. Good deal for $4, cancel any S&S.
