Great Flavor

I enjoyed the flavor of the magnesium powder and it was easy to dissolve. The supplement allowed me to fall asleep easier and I woke up refreshed.

The Member’s Magnesium Powder

The member’s Magnesium powder is a great option for relaxing before bedtime. It blends Magnesium with L-Theanine and restful sleep. Without melamine

Verified Purchase

Not so good. ☹️

Bought for my daughter. It tasted good but gave her stomach upset, so she did not want to take.

Better than the name brand!

I have no idea why there isn't a review on this yet! From someone who takes melatonin and magnesium glycinate everynight, I drank this the 1st night I bought it and was out within an hour! I've been consistent every night for a week now, and not once have I had to take any sleeping pills, still fall asleep fast (which is a miracle in itself), and have a deeper sleep. You get accustomed to the cherry flavor. Such a great product!

Better out there

This powder is very grainy/chalky and it smells/tastes like cherry medicine. I've tried using hot water to see if it would better mix, but that didn't work. Stirring for over a minute straight didn't work either. I've tried the recommended 6-8 oz of water, but that just prolonged drinking it, so I've been using as little water as I can so that I can just chug it and get it down. All that being said, I do feel like this product works. Within 30 minutes it kicks in and I feel peaceful and calmer. I'll continue to use this jar up, but I'm definitely on the lookout for something that doesn't have this grainy issue and the smell. I like cherry, but this is just too artificial tasting.

Not for me

I bought it since the Magnesium Glycinate tablets have been removed. It has Mag Glycinate along with other forms of Mag. For me, the additional Mags along with a different dosage do not agree with my stomach. Also, I'm not a fan of stevia so the sweetener tastes lingers. The cherry taste is bordering on cough syrup, so it takes awhile for me to finish a glass. I hope they bring the tablets back soon.

Very Good Product

Great product to help you rest well and feel restored upon waking up. I'm seeing complaints about taste, keep in mind this is not a margarita it is a supplement. The taste is not bad at all for this product. I would suggest this powder to anyone and hopefully Sam's makes this a permanent item for sale.

The taste is awful. It tastes like artificial cough syrup, its honestly so bad. I wish they just kept the tart cherry flavor.

At first, I didn't feel like this worked that well. But the more I take it, the better it works. My husband sleeps better too.
