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.
I have been using thus brand for several years now and am pleased with the quality.
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!
Like; Great for nerve numbness
No added fillers...actually improved my bloodwork
easy to swallow
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.
[This review was collected as part of a promotion.] This has honestly been my secret weapon for getting through the week. Between work, school pickups, and barely sleeping with a 5 month old, my stress levels have been so high. Sleep has been a huge struggle for me, which isn't the norm. My husband has taken magnesium for a while and he recommended that I give it a shot. I'm so glad he did. I take these before bed and I fall asleep so much faster and actually stay asleep. I also wake up feeling a bit more energized. It also helps my jumpy legs! If you're a tired, stressed-out mom, give them a shot!
[This review was collected as part of a promotion.] There are several different magnesium's that all offer different benefits. This one pill covers most of the bases. Helps me rest at night. Relieves sore muscles and keeps my digestive tract regular without stomach cramps. I take them every night before bed. The pills go down easy.
[This review was collected as part of a promotion.] I've been getting into vitamins and supplementation recently and this is my most recent addition to my routine. I think I've finally perfected my regimen by adding this magnesium because I actually feel like I'm sleeping deeper and wake up more well rested! If you're on the fence about all the supplements out there I would definitely give this one a try- it's legit!
