I buy these from iHerb and they are great but with Amazon I would not risk it. They do not keep inventory in a fully climate controlled warehouse. As someone who works for Amazon I know how hot and humid they get in some of the warehouses during the summer months. Everything else I'll buy with out hesitation but supplements are a no go for me

I bought these a few months ago and they smelled rotten. I think they lowered the price because a lot of people stopped buying them for this reason

I have these. The pills are big and chalky and a pain to swallow. And I have no issue swallowing multiple pills at once.
Once I am done I will look for another brand. Just FYI.

I take one pill of 100mg in the evening and that is plenty. With supplements, it is best to practice "less is more" so always try a lower dose first. Never fall in the trap of thinking more must be better.

I used to really like this brand until they were sold to a Chinese company that sources some of its products in China. Can't trust it anymore.

Magnesium supplement dosage isn't something most can determine by "trying"

I've had this for a while but never use it because magnesium glycinate knocks me out and leaves me in brain fog for a whole day after. Like taking a benadryl. Even using a pill cutter I only use around 1/8th of these giants a few hours before bed. I currently use magnesium taurate instead. No drowsiness at all with those.

Kirkland's Magnesium Citrate was $19 for me for 33.75 grams of Magnesium (270 ct * 125mg/pill).

By my math, $19 for that Kirkland's bottle is about the same unit price as this post, so if you've been wanting to get Magnesium, I'd suggest you get it from Costco if it's around $19 at your store.

I guess everyone's body physiology is different, I've been taking this exact brand for years, 2 pills every night, sleep like a baby and good for my muscle recovery from daily workouts. Love it!

I just thought I would chime in that this is applicable to a wide range of their products. I have previously (more than six months ago) bought this brand based on what I read about it on Reddit and was pleased with the quality; I wasn't aware that this company had been bought out by a Chinese corporation or anything regarding their warehouse. I'm on a fixed income and just hoping they're the same quality that they were.
I got 120 tabs of 500mg ALCAR for just under $10 with Subscribe & Save; there's some decent deals on methylated b vitamin compounds, too.

Where did you hear about that? Now brands has been one of my go to supplement manufacturer and I have never heard of this so I just tried looking it up and couldn't find any info on Now Foods being acquired by a Chinese company. It still seems to be a family owned company from the 5 minute Googling I did.
That being said, it's probably very difficult to know what the country of origin is for many of the supplements and food ingredients we consume as the laws are pretty lacking.

I think the packaging is confusing you (it is definitely confusing). Pull up images of the two brands with Google.
Now Brands is a very reputable company that does appear to be American and family-owned. Source: https://www.healthline.com/nutrit...%20process. (2023, but their website implies the same)
This is Doctor's Best. It was apparently acquired in 2016 by a Chinese company. Source: https://www.nutraingredients-usa....Group%20Co.
I know I have bought supplements from Doctor's Best company since then without trouble. That's not to say they're as good as Now, especially for things other than your ordinary letter vitamins, etc.--Now is my "go to" for inexpensive supplements, too. If I had a better budget, I'd prob just buy everything from Now or Thorne or Jarrow. But as is--will try them again.

This is Doctor's Best. Not Now Brands. They were bought awhile ago but they had recently changed the sourcing of some of their products to China and they had also changed their labeling. A lot of people who are into supplements are leery of products that are sourced in China due to lax quality control where toxic minerals sometimes find their way into the products.

Magnesium citrate and glycinate are two entirely different animals. https://www.health.com/magnesium-...te-8783552

Citrate will make you go poo.

Glycinate helps with pain and sleep.
