Size: 90 Count (Pack of 3)
This is exactly what I needed for my daily health routine. I appreciate that it's made from marine magnesium and includes avocado oil for better absorption. The clinically tested aspect gives me confidence in its quality. The 3-pack is convenient and ensures I don't run out quickly. Overall, a perfect supplement that meets my expectations for natural sourcing and effectiveness.

Perfect for me!!
Size: 90 Count (Pack of 1)
This was always my most favorite Magnesium supplement until Smarter Nutrition replaced it with another formula. Marine Derived Magnesium helped me fall asleep and more importantly, by shutting off my thoughts so that if I did wake for any reason, I was able to drift back to sleep quickly!!
Am so relieved that they've brought it back! 😴

Size: 90 Count (Pack of 1)
This product is great. I appreciated the avocado oil included and that it's naturally sourced. It helps support sleep, bones, and muscles, which I need. The only thing is, I wish it absorbed faster. Still, overall, a good supplement for daily use.

Great supplement for overall health benefits
Size: 90 Count (Pack of 1)
I really like the features of the magnesium supplement. The fact that it's non-GMO and naturally sourced makes me feel better about taking it daily. I noticed improved sleep and muscle recovery after workouts. Including avocado oil and trace minerals is a nice touch. Overall, a good product for supporting bone, sleep, and muscle health.
