I prefer the soft capsules but these are okay. Magnesium is recommended along with Vitamin K2 for absorption of Vitamin D3. Vitamin D alone cannot be absorbed by the body and is simply stored. K2 and Magnesium together with the D3 work to allow absorption by the body. Before Covid I was put on a prescription Vitamin D three separate times and my Vitamin D level remained in my boots, very Low level. When Covid hit us I had learned, so I began to take 10,000 and then 20,000IU of D3 with 500 mg Magnesium and 100 mcg K2. At my next check up my Vitamin D level was thru the roof. When I got Covid a couple months ago it was a mild case, and my lungs were not affected (no breathing difficulties). I’m considered elderly and was told it was because my immune system is strong that my body handled Covid so well. I also take Zinc, NAC, Nattokinase Enzyme (to dissolve fibrins in the blood that produce blood clots), and Krill Oil; these are all very important to fight Covid and the many side effects of the vaccine.

Bye bye leg cramps!!!

Linda March 24, 2021

Ive used another brand of magnesium for years for leg cramps and they've always worked until a few months ago, and so I upped the dosage but after a short while, that did not work either. So, I read the reviews on this one and thought Id give it a try. Well, Im glad I did because it started working after the first dose! No more leg cramps when I go to bed! Its amazing!

ProudMomof3 March 21, 2025

These Magnesium supplements by NOW seem to continue to help me, however from time to time they don't seem to work as well as others, but could just be age/ weather working against them. These particular NOW brand 400MG Magnesium caps have become a little harder for me to find in store so I've had to order the last few bottles online. Similarly to the way I had to buy a different brand Biliberry (I use for eyes) , before it became completely unavailable. Fingers crossed this isn't the same though it feels like it.

Sore muscles under control

Allie L May 21, 2026

[This review was collected as part of a promotion.] I learned that even if you follow a clean fruit, veggie, meat filled diet you're still probably magnesium deficient so I tried adding these in because I get a lot of knots and really achy muscles. It really does seem to take an edge off of muscle aches and pains. Plus, it's supposed to help with sleep a ton and also has other benefits too, so I can't wait to feel even more benefits from it. But right off the bat I'm giving it five stars for helping with muscle soreness.

Staple!

Brooke C April 30, 2026

[This review was collected as part of a promotion.] I love magnesium for sleep, relaxation, and recovery. I trust Now Foods, and products like this are why. Packaging was perfectly intact, capsules are not hard to swallow, and I feel all the benefits promised. I like how these are 400mg, as it’s the perfect dosage for what I’m looking for. I’m glad I stated implementing this in my youth, as I can reap its benefits the rest of my days.

Supports Recovery

Hannah W May 5, 2026

[This review was collected as part of a promotion.] I've been taking Magnesium as part of my routine, especially since I work out a lot and wanted something to support recovery and it's been a great addition. I mainly take it to help with muscle recovery and relaxation, and I've noticed it helps me feel less tight and more recovered after workouts. It's also been a nice support for winding down at night. The capsules are easy to take, and I appreciate that the formula is straightforward without a lot of extras. I also like that it's GMP-certified, which gives me confidence in the quality and how it's made. Overall, a simple, reliable supplement that fits really well into an active lifestyle!

Simple Night Routine Staple

Alina K May 12, 2026

[This review was collected as part of a promotion.] I've been using NOW Foods Magnesium 400 mg for a while now, mainly as part of my evening routine. I like how simple it is to add into the day—just one capsule, no extra steps or complications. What I appreciate most is that it feels like a straightforward, no-fuss supplement. It includes multiple forms of magnesium, and I've noticed it helps me feel more relaxed in the evenings and generally less tense after busy days and workouts. The capsules are easy to take and don't cause any stomach discomfort for me, which is important because not all magnesium supplements feel that smooth. Overall, it's become one of those basic staples I keep using consistently because it fits easily into my routine and supports my active lifestyle without overthinking it.
