Tastes great, mixes well, and feels easy to add to

I’ve been trying the Member’s Mark Magnesium Powder with L-Theanine & Tart Cherry for a few nights now. The flavor is really pleasant, and it mixes into water smoothly. I also appreciate that it doesn’t leave me feeling tired or groggy the next morning, which has happened with other sleep aid products. I haven’t noticed a dramatic change in my sleep yet, but I plan to keep using it to see if the effects build over time. Overall, it’s easy to take and enjoyable, and it feels like a nice addition to my nighttime routine. Nice storage container and well packaged.

Helps with sleep

I've been pleasantly surprised with this magnesium sleep powder. The flavor is actually pretty enjoyable and mixes well without being gritty or chalky. I noticed it helped me wind down at night and made it easier to relax before bed, which has definitely helped my sleep routine feel more consistent. I also woke up feeling less groggy than I expected. The only reason I'm not giving it a full 5 stars is that I wish the effects kicked in a little faster, but overall it's been a great addition to my nighttime routine and I'd buy it again.

Best drink before bed 🍒⭐️

This product smell EXACTLY like cherries! 🍒 the consistency is spot on. The serving size is perfect for right before you’re supposed to go to bed. The dissolvability is spot on. It is not grainy at all, and the frequency is amazing! 10/10 ⭐️⭐️⭐️⭐️⭐️

Works well, tastes gross

Mixes in water easily, and dissolves well. It will last a long time, according to the expiration date on the bottom! It seems to work really well, but ma the taste and smell are awful.. it tastes like cherry cough syrup. I choked it down, and I slept great but it will likely not become a nightly routine for me, unfortunately

Tasty cherry sleep tonic

This is one of the better tasting sleep drink I’ve tried. The cherry flavor is tasty, and it’s easy to scoop out and mix up! There is a little mineral deposit left in the glass, but it’s the same as other similar powder supplements. I recommend trying it!

Not for me

This is a very decent sized portion for the price and did not taste bad, but unfortunately did not work for me. I slept hard but I felt hyperactive instead of relaxed. I wish this would have worked for me because I love sleep aids and sometimes need help in that area.

Great taste but effective

This powder is the magic step in falling asleep and staying asleep, not only does it work but it also tastes great. I don't mind drinking this and that's a huge plus!

Pass

I didn't find this product to help with sleep at all. The taste was awful. It was like drinking cherry cough syrup. It didn't dissolve and mix well either
