Nutricost Magnesium Oxide 750mg, 240 Capsules - 420mg of Magnesium, Non-GMO, Gluten Free

I took Magnesium Oxide for years, originally for leg cramps and also to help me sleep. The only time I realize how good it works is when I run out and suddenly the leg cramps return. Anyway, the last order before this one I decided to do some research on the types of Magnesium and fell down the internet rabbit hole. I feel like I should have a degree in Chemistry at this point! Basically; I thought Magnesium Malate might be a better form for me, I have Fibromyalgia and read it was good for that, I read about bioavailability, etc. Magnesium Oxide was said to have one of the lowest biovailability rates of all magnesium forms (that's how well the body absorbs/utilizes it). So I switched to a Magnesium Malate. But in order to equal the dosage I was used to with the Oxide form I had to take 3 giant malate pills. And it cost more to begin with. So it was more expensive, more pills to take, and 4 months later the bottle was empty and I felt no improvement whatsoever. It worked fine, just not any better. So I returned to the Oxide form this time around. Incidentally, the Oxide form has one of the highest amounts of elemental magnesium, so that may outweigh the lower bioavailability factor, but who knows for sure. So I'm trying this particular brand of magnesium oxide for the first time. It was a good combination of a fair price, good strength, and good quantity in the bottle. In case anyone read the label and is confused about the amount of magnesium in this product, let me attempt to explain it: Magnesium Oxide is the compound (aka blend, or formula). So there's 750mg in the compound. The elemental magnesium (actual magnesium portion of the compound) is 420mg. That's the number that matters most, as far as how much magnesium you're getting. As an example; my old brand of Magnesium Oxide was 500mg and mentioned nothing about the elemental magnesium content on the label, so for years I thought I was getting a full 500mg, but it turns out it was really only about 300mg roughly of elemental magnesium, so this brand actually has more magnesium. I was surprised to see these are capsules. It clearly says it's capsules in the description but I was so busy checking the other details that I hadn't even noticed. I've always taken magnesium in large tablets, so this is a bonus as far as I'm concerned. And only one capsule per day is needed for that 420mg of elemental magnesium, which is better than the three giant pills I was taking in the malate form. I'll update this review if for some reason these don't work out, but these appear to be good quality; they're gluten-free, non-GMO, and made in the Good Ol' USA. UPDATE: 6 1/2 years after writing this review, I still recommend it and have reordered numerous times.

If you're like me, you take several grams of Vitamin C everyday for the radical scavenging. The lipo form is great, the esters are great, but they get expensive. The best bang for the buck is pure Vitamin C, which is L-Ascorbic Acid. But taking fat servings at night, especially on a relatively empty stomach, can cause sour stomach. It's rather acidic at high amounts. But I also take Magnesium at night, and this Oxide form is quite basic. So taking 750mg Magnesium Oxide with 1-2g of Ascorbic Acid initiates an inevitable redox reaction in vivo, producing a good bit of Magnesium Ascorbate, and mineral ascorbates are absorbed quite well also! This allows me to take 2 inexpensive forms of nutrients I like and end up with a superior form, while neutralizing the side-effects of each simultaneously. It works well with my regimen and saves me money too. Other forms of Magnesium could not be applied like this, only the Oxide will yield this benefit. (Or the Hydroxide, which is an intermediate.) Nutricost has proved to be a good brand in my experience, and I'm a nutraceutical formulator who has tried (and assayed) about 1/3 of their products.

This is kind of gross but: Y’ALL. I am doing the JJ Smith 10 Day Green Smoothie cleanse to try to lose weight for a vacation. You’re supposed to have 2-3 bowel movements a day if you’re regular. I’m 22. I’ve ALWAYS had 1 bowel movement like every 2 days. 1 per day if I’m lucky. JJ Smith recommends Mag07. It’s like $40. If I felt it was worth the price I would’ve bought it. I’m a supplement freak, I take so many vitamins. But I read these reviews and said this is a 1/3 of the price and it’s the same thing! I took 5 of these before bed. Around 7 am I woke up. THEY WORK. I’m so happy with it. I used to do ballerina tea but it has senna and cramps your stomach and chains you to the bathroom. Like you can’t go to work. This stuff doesn’t cramp your stomach and it works JUST as well as Mag07. I’ve never tried Mag07, but they promise the SAME things and this one delivers the SAME result Mag07 would. Save your money and buy this one! And no, I wasn’t sponsored or anything. I made this review to help my backed up people lol! I’m also thinking about getting a colonic!

Some capsules were broken and spilling powder in bottle.

This magnesium supplement is super good and comes in quantities that can last you up to 3 months. I highly recommend it.

good buy

It works really well for me and it came in a timely manner

After purchasing these, I found out that oxide is not the best magnesium to purchase and I wasted my money. Please check with your doctor as there are so many different types of magnesium out there. Oxide is the least effective according to my doctor.

Just as advertised

Llevo pocos días tomándolo pero me ha funcionado muy bien. Lo super recomiendo

Fast shipping

Great size, value, product.

Me gustó el magnesio de nutricost porque me ayuda a relajarme y dormir bien.
