Magnesium, necessary for life
Magnesium is the most important mineral in your body. Lose your magnesium and you lose your life. Magnesium is a vital catalyst in enzyme activity, especially the activity of those enzymes involved in energy production. It also assists in calcium and potassium uptake. A deficiency of magnesium interferes with the transmission of nerve and muscle impulses, causing irritability and nervousness. Supplementing the diet with magnesium can help prevent depression, dizziness, muscle weakness and twitching, and premenstral syndrome (PMS), and also aids in maintaining the body's proper pH balance and normal body temperature. Magnesium is necessary to prevent the calcification of soft tissue. This essential mineral protects the arterial linings from stress caused by sudden blood pressure changes, and plays a role in the formation of bone and in carbohydrate and mineral metabolism. Magnesium is a factor in helping to prevent cardiovascular disease, osteoporosis,kidney stones, chronic fatigue, insomnia, irritable bowel syndrone, and a multiple of other diseases brought on by a lack of this essential mineral. I have taken 1/4 of a teaspoon of magnesium in a 8 oz. glass of water twice daily since 1989 for hypertension and it helps me maintain a normal blood pressure. Magnesium is most inexpensive, miracle mineral you will ever take. I highly recommend it.

Good Quality
Any and all of this type of product should be fully researched by the user before use: to fully understand the effects, benefits, and any side effects. I have been using these for quite a while now, the result is obvious to me, however, it is very difficult to explain. I intend to continue to use these products, using caution to stay within the suggested dosages.

Good Quality Magnesium , But tablets Are too large
The magnesium supplement appears to be good quality and the ingredients are fine. However, for me personally, the tablets are too large and difficult to swallow. If you don’t mind bigger tablets, this may not be an issue, but it’s something to consider before purchasing.

Big pill, treacherous bottle
Pro - 200 mg is a good dosage. I had previously been taking a 500 mg capsule but it was too much (definitely solved my constipation problem though!). Cons - the pull tab on the foil cover broke off at the first yank. I used scissors to break the foil and then ended up with a deep cut on my thumb pulling the foil off the rim of the bottle (wouldn’t stop bleeding). The pill size is HUGE. And it’s not an easy to swallow capsule like my 500 mg one. A pressed pill with edges and no coating. I was able to swallow it but if you have trouble with large pills, suggest getting a capsule version again. I will finish the bottle but will look for a different product next time.

Hey, it works!
It works very well as a gentle laxative! Senna tea, milk of magnesia, and other laxatives have me sweating, running to the toilet, and wishing it would all end while I regret my life choices. Come on, we’ve all taken way more than the “recommended dose” because we wanted quicker relief… but at what cost? Well, I can happily say, not this one. This one is so nice to me. It’s much more gentle and just as effective without the pain and suffering. I take a tsp mixed with cold/room temp water. It dissolves very easy. A little confused by the comments stating otherwise? Also, this is A LOT of magnesium oxide powder. I don’t see any reason you would ever need to buy this again. I bought this to help with phase 1 of Dr. Bakker’s Candida Crusher protocol. Not because of constipation. I’m trying to reset my gut, and kill those nasty buggers proliferating in my tummy! I take a heaping tsp with water on an empty stomach either in the morning, or at night before bed. And boy howdy, it works like a charm!
