Review: Good Mag Strength & Price - 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.
Review: MgO is the best form, in certain situations - 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.

## Questions & Answers

**Q: I want a cheaper version of MAG 07 for a cleanse, is this close?**
A: It didn't work like the Mag 07 for me I didn't get that good cleanse of bowel movement

**Q: Is this product natural?**
A: I'm really not sure, but I'll give you the Nutricost Website, and you can ask them.   https://www.nutricost.com/products/121/magnesium-oxide

**Q: Is this 750 mg oR 420? Why does it mention both numbers?**
A: Q & A Does this Magnesium Oxide have 750 mg or 420 mg of magnesium per serving? Why does it mention both numbers? 
* The amount of (pure) Magnesium per capsule is 420mg, the amount of Magnesium *Oxide* 750mg.

**Q: The bottle i received has 420 mg under supplement facts but it also has 750 mg on the front label, what is the actual amount of magnesium per serving?**
A: Yes, it is incredibly confusing and I don't know why we can't get an actual answer to this. I don't know how to dose it. I had been taking Twin Labs Mag. Oxide, 400 mg of magnesium (as magnesium oxide). This bottle says 750 mg of magnesium oxide on the front, then 420 mg of magnesium oxide (as magnesium oxide).  So how can it be both, and which one do you use as equivalent to Twinlabs 400 mg?  Why can't we get a clear explanation of this- 750 vs. 420?
