NOW Supplements, Magnesium 400 mg, Enzyme Function*, Nervous System Support*, 180 Veg Capsules

After about a week of taking one capsule at night, I began to realize I was waking up with awful headaches every morning. I stopped taking and my headaches haven’t returned. Not sure why this happened but I guess I’m better off without this supplement.

Magnesium is a cofactor in more than 300 enzyme systems that regulate diverse biochemical reactions in the body, including protein synthesis, muscle and nerve function, blood glucose control, and blood pressure regulation. As we get older our body creates less. I take them before bedtime for better quality of sleep. It works, I promise.

Now products not only work for me but give me value.

So Im usually happy with this brand of magnesium, but the last bottle I got has a strange odor and funky, salty taste. Ive taken two of them, both at night when I wasnt fully paying attention, and each time I thought... yuck!! I finally checked this bottle out and compared it with another unopened bottle I had on hand. Something is definitely wrong with this bottle, although Im pleased that it didnt make me sick. So normally a good brand, but perhaps a bad batch? Lot# 3236432 best by 12/2026

You can trust NOW for quality and absorption

I’m a repeat customer for these Magnesium caps from NOW. I take them at bedtime to help me sleep and avoid leg cramping. I’ve used this same product for several years. I always buy NOW brand vitamins and supplements. This is a great product for anyone looking to improve their sleep (it is not a sleeping pill tho) and help with any type of leg cramping or restless leg issues. As Magnesium is a trace mineral you can’t really be tested to see if you are deficient but many people are. A good supplement can help you sleep and rest better, amongst other things.

I very seldom would remember my dreams... and since taking Magnesium, Ive remembered my dreams. Dreams of many things and people. I have MS, Thyroid, Arthritis, and now diagnosed with Osteoporosis - So my research has taken me to supplements I would have never imagined to be taking. So is it the Magnesium that has been helping ?? Along with the few other daily supplements Ive added to my daily routine Im pleased to say I think it has... Ive done so much research in which supplements to take, and Ive added some that I would probably never have taken. Ive stopped some too as I learned some were known to help with the same thing so I chose which to continue taking.

I tried other brands but this is the only brand that stop my leg cramps

Kind of hard to swallow

Magnesium is awesome for calcium absorption ! We get the same ratio of calcium and Magnesium , we know that calcium by itself does not help a bit, because calcium by itself gets our bones as egg shells, super hard which makes them to break easily and inside basically hallow. So with equal ratios we do amazing!
