Verified Purchase

Big Pills

These turned out to be pills, not capsules. Their size makes them impossible to swallow. Even cutting them in half still leaves then too large to swallow. Why would you even sell something like this?

Magnesium glycinate supplement

Supplemental to support heart, bone, nerve and muscle health. Good size packaging. Easy to open bottle. The pills are very large. Slightly hard to swallow. There is no taste or after taste to the supplement.

Bring this back to stores and online

I use this every single night before bed. It helps me relax and have a good nights sleep. I've been checking online and in stores and can no longer find this item. Please, please, please bring it back. I will soon be running out and the alternative brand is double the price.

Good product

Member's Mark Magnesium Glycinate with L-Theanine is generally praised by users for its effectiveness in promoting relaxation, improving sleep quality, and being gentle on the stomach, with the added benefit of L-Theanine for stress response and overall good value from Sam's Club. However, I find the large, chalky tablets difficult to swallow and note that effects may take a few days to become fully apparent. Please make it in the form of gummies or a soft gel to facilitate swallowing for people who dislike feeling pills in their throat. I will update my review after using it for a month.

Great

I've been taking Member's Mark Magnesium tablets for a while now, and I can really feel the difference. The tablets are easy to swallow, and I like that they don't upset my stomach the way some other brands do. I've noticed improvements in my sleep quality and less muscle cramping after workouts. The bottle is a great value for the price—you get a generous supply that lasts a long time. I definitely recommend these if you're looking for an affordable and effective magnesium supplement.

Bring this back! Please!! This supplement works great and the tablet is so much easier to take than the capsule. This is one of 2 products that Sams carries that I renewed my membership for. Now it's gone. No need to renew next year. Can I have a refund on the remaining 9 months of my membership?

Great Supplement!

This is really good to use for bone, nerves and muscle health. Helps me feel better and seems to really work with getting better sleep at night, I don’t feel nearly as restless as I did before. Easy to open and get the pills out of. The pills are large but easy to take.

Great magnesium supplement

I have used magnesium for years now and was so happy to find this one that Sam's carries. I have taken these for a few weeks now and they work great for me. I normally have problems getting to sleep, but these help tremendously. They help relax me and i am able to stay asleep longer now. I can even twke just one and get the same results. My only issue ia the size of the pill, but that's just a personal thing and i am able to easily cut them in half.

Really changes how you feel about yourself

I started taking these supplements because I heard they were really helpful for me and my body and I was really happy I started taking them. I really noticed a change in my wellness after taking them for about a week. My body wasn’t feeling weak anymore and I really enjoyed getting my sleep schedule together. Overall I feel better and I 100% recommend this product.
