first, let me correct the misinformation that "Mikke" (the 1 star review) posted to everyone. rather than allow his comment to immediately scare off gullible readers who were considering this product, let me explain to them why his "review" is irrelavent and incorrect.
first, the parts that he did partially get right: yes, this product does have talc listed as one of the ingredients. yes, talc once carried ties to cancer. do you know *why* it was linked with cancer? i'll enlighten you: because talc, in its natural form, contains asbestos -- which is curious, since asbestos is also linked to cancer? see, back pre-70's, they used talc powder in its natural form, which brought with it asbestos. in the 1970's sometime, they realized that asbestos was trouble, and they started manufacturing processes to remove asbestos fibers from the mined talc. let's see what groups with more credibility have to say about talc:
The U.S. Food and Drug Administration (FDA) considers talc (Magnesium Silicate) to be generally recognized as safe (GRAS) for use as an anti-caking agent in table salt in concentrations smaller than 2%. [ source -- [...]]
The International Agency for Research on Cancer (IARC) is part of the World Health Organization (WHO). Its major goal is to identify causes of cancer. Based on the data available, IARC classifies talc that contains asbestos as "carcinogenic to humans". It classifies talc not containing asbestos as "not classifiable as to carcinogenicity in humans".
In its natural form, talc may contain asbestos, a substance known to cause cancers in and around the lungs. Because of this, all home-use talcum products have been asbestos-free since the 1970s. [ source -- [...]]
what he is spreading is information that is decades old. though he rated the product 1 star, but i'm quite sure he never even tried it, because it is carcinogenic, right? who's gonna eat "cancer pills"?
now let me offer up my review of this product, as i have actually used it before.
first, i will endorse this product for the form of magnesium that they use. if you have done any research, you will know that there are many different forms of magnesium in supplements, the majority of them using the horrible "magnesium oxide", which has poor absorption and is cheap. if anything, this would be the form to avoid. FDA studies back this information up. you have the better (chelated) magnesium forms -- you will read these are more highly absorbed forms, and you often see the advice to make sure to get "chelated" forms. these are forms like aspartate, glycinate, glutamate. all this means is that the magnesium is bound to another item your body can use (amino acids most often), which makes it easier for the body to break down, since it already has enzymes to process amino acids that come from your food). magnesium citrate is not an amino acid form, but is tied to citric acid, or vitamin C. magnesium citrate is one of the "runner up" best forms, so failing this form (chloride), i recommend citrate.
now, we come to the form that is in this supplement -- which is magnesium chloride. this is regarded as one of (if not "the") most bioavailable (or best absorbed) forms of magnesium that you can get. so, if you get sticker shock when comparing this to other supplements you might see sold online or in stores, just remember this: you get what you pay for. that bottle of 250 pills for $2.99 is going to be magnesium oxide, and you're mostly wasting your money. this may be a little more expensive, but it is of much higher quality, and you will get much more benefit out of this than the cheap stuff.
also realize that all three of the ingredients in this product (magnesium, calcium, chloride) are all important to neural function, as they are ions that are absolutely fundamental to brain and nerve function. potassium is another. you may remember Ca++, Cl-, K+, Na+ ions and "action potentials", etc when studying how nerves work. it's important to know that they compete for the same absorption sites -- they all have to go through the same "door" to be absorbed. for this reason, there are specific ratios which ensure that we do not absorb an "uneven" or "excessive" amount of one these nutrients. this ratio is generally deemed as 2:1 for calcium to magnesium, therefore, to make sure you don't get too much calcium and not enough magnesium absorbed or vice versa, it's important to respect this ratio. as you can see, this product roughly adheres to that ratio, having about double the amount of calcium that it does of magnesium. that's not just coincidence!
a large population of people have magnesium deficiency (usually the problem is excessive calcium vs. low magnesium), which creates an imbalance all throughout the body, and can cause a very wide range of medical problems that often go undiagnosed as a simple mineral deficiency. most doctors are too quick to just throw you on some prescription medication to deal with the "symptoms", not the "problem". you have RLS? magnesium can help tremendously in RLS sufferers... but what will the doctor give you? well, i probably can't mention brand names, but there are medications they will give you to treat RLS (major one starts with an "R"), but with horrible side effects (strong nausea, dizziness, etc). not only that, the Rx is incredibly expensive and it is merely a temporary band-aid to mask the problem. when you quit taking the Rx, the problem rebounds, and you end up with much worse RLS than you even had before starting the medication! unable to take the agony of this worsened condition, you run back to the Rx for comfort. another physically dependent patient. ah, big pharma loves those! what about another symptom of magnesium deficiency -- anxiety? we all know what will happen if you complain of that to a doctor -- again... i'll mention no names (one of the most popular ones starts with an "X"), but we all know of someone who pops these extremely addictive benzodiazepines. unfortunately this includes myself -- i originally started taking them for RLS and anxiety at age 20, when i was naive and didn't know any better... that was 10 years ago. after being on them for a decade, i'm now so physically dependent on them, i cannot even taper off of them, though i want to. withdrawal from them can cause seizures, delerium, intense agitation, and long-term users who are actually able to get off of these drugs suffer lingering low-grade withdrawal", lasting for months or years afterwards. these aren't scare tactics, this is reality and the condition of modern medicine's approach to these common problems. heart arrythmias? excessive calcium and low magnesium will cause the muscles of the body to contract with more force and frequency. magnesium is calcium's counter-balance... it slows things down. keeps things from getting overly stimulated. it will help relieve muscle tension, cramps, heart palpitations, etc. insomnia can be helped, as it will calm your mind and body down... i could go on forever about how many common medical conditions could be no more than a simple magnesium deficiency. wouldn't you at least try a danger free, natural approach for 1 month before considering Rx meds? you'll be taking minerals that your body needs anyway -- minerals that you can stop taking cold turkey at any time and not go into intense withdrawals like you would from most Rx drugs used to treat these problems?
so i will stop with the reasons why you should chose this product if you are considering magnesium supplementation... here are my only complaints or concerns about this product:
1) it is expensive. let's be honest. it can be had for the cost of about $10 for a month's supply from here or... the biggest national retailer. each box comes with a coupon for $1 off your next bottle of Slow-Mag. so even though the cost is high, i'd rather pay the premium for a superior product.
2) the amount of these minerals is rather low compared to other supplements, or even the FDA's daily recommendation of 400mg. the description is a bit misleading unless you read the full data. it is also different from what the product manufacturer's website says. the manufacturer's site claims that it supplies 143mg of magnesium (for 2 tablets a day, which makes 1 bottle last one month) and 238mg of calcium, plus chloride, which isn't even mentioned here. these amounts are higher than what is listed on amazon's page. this is what is shown on the offical label:
Calcium 238 mg 24% DV
Magnesium 143 mg 36% DV
Chloride 405 mg 12% DV
but my point is, in either scenario -- this is a pretty low amount of your % DV, for 2 pills and the cost. to get the full 100% you'd have to take roughly 6 of these a day, making a bottle last you a whopping 10 days! that's a dollar a day at the cheapest. that is the only thing that bothers me. true, you will probably absorb more of the product even at these lower amounts than you would of the cheap ones, but i'm wondering how much. apparently people are finding relief in symptoms, so the efficacy must be there, regardless of it being a fraction of what is called for. overall, i would say this product is worth the price and is of better quality than most all other brands you will find, especially the junk you'll find at your everyday retail stores.
check out their website for more info. and btw, i do not work for the company or have any ties to it, i just believe they make a quality product.
