http://www.drrons.com/beware-of-additives-in-supplements.htmMagnesium stearate, stearic acid and calcium stearate, made by hydrogenating cottonseed or palm oil, are used throughout the supplements industry as lubricants. They are added to the raw materials in supplements so that production machinery will run at maximum speeds. These fatty substances coat every particle of the nutrients, so the particles will flow rapidly. This ensures that production schedules will meet profit targets.
Cottonseed oil has the highest content of pesticide residues of all commercial oils; cotton crops are heavily sprayed. In the hydrogenation process, the oil is subjected to high heat and pressure in the presence of a metal catalyst for several hours, creating a hydrogenated saturated fat. Hydrogenated vegetable fats contain altered molecules derived from fatty acids that may be toxic. The metal catalyst used in the hydrogenation process may also contaminate the stearates produced (see Erasmus, Fats and Oils).
While toxicity is one problem, decreased absorption is another. In a study published in the journal Pharmaceutical Technology, the percent dissolution for capsules after 20 minutes in solution went from 90% without stearates to 25% with stearates. This delays the absorption of nutrients. Individuals with impaired digestion may have particular difficulty absorbing nutrients coated with stearates.
Another problem with stearates: concentrated doses of stearic acid suppress the action of T-cells, a key component of the immune system. The article “Molecular basis for the immunosuppressive action of stearic acid on T cells” appeared in the journal Immumology in 1990.

Companies that manufacture and transport magnesium stearate must file a Material Safety Data Sheet with the Environmental Protection Agency because concentrated magnesium stearate is classified as a hazardous substance.
* Its uses are listed as “ammunition, dusting powder, paint and varnish drier, binder, and emulsifier.” The section “Human Health Data” states that “Inhalation may irritate the respiratory tract” and “Acute ingestion may cause gastroenteritis.”
* Under the heading “Regulatory Information,” the paper states, “This product is hazardous under the criteria of the Federal OSHA Hazard Communication Standard.” This information may be viewed at the web site
www.hummelcroton.com/msds/mgstear_m.html * Supplements manufacturers pass off magnesium stearate as a benign form of magnesium. Magnesium stearate is the magnesium salt of stearic acid, which is also used in supplements for the same purposes. The argument is made that small amounts of these substances do no harm. But do you really want them in your supplements every day? Remember, the sole purpose of using these substances is to make the machines go faster. Supplements can be made without them-it just takes more time, care, and attention to detail.
How Much Hydrogenated Lubricant Oils Are You Getting With Your Supplements?
Up to 5% of the average 1000 mg capsule or tablet is magnesium stearate. That’s 50 milligrams. Suppose you take 8 capsules or tablets a day. That’s 250 a month – or 12,500 mg of this hydrogenated oil, nearly half an ounce. That works out to about 6 ounces of hydrogenated oils a year, from just 8 pills a day. Many people take more supplements, and ingest pounds of this toxic oil we try to avoid in our diets – while directly inhibiting the utilization of the nutrients they’re supplementing!

Hi Doug,
I have been hearing a bit about the dangers of magnesium stearate, found in, among other things, 95% of supplement/vitamin pills. Can you comment please?
Hi J,
This issue has raised a lot of debate in the supplement community as of late. A few supplement companies and health experts have begun claiming that the ingredient "magnesium stearate" is toxic. This has caused quite a stir because, as you've said, magnesium stearate is listed as an ingredient in the vast majority of vitamin supplements on the market. In fact, you'd be hard pressed to find a supplement in the health food store that doesn't contain this substance listed under "other ingredients" (I was).
Let me start off by saying that I have yet to find a definitive answer on the subject. Most of the articles you'll find on the internet about magnesium stearate are not only alarmist but wildly misinformed. Magnesium stearate is a compound that combines magnesium salts with stearic acid, a saturated fat found in nature. Most of the articles I found on magnesium stearate equated it as the same thing as stearic acid, which is not entirely true.
Stearic acid is an 18 carbon fatty acid. That's it. It isn't necessarily hydrogenated (although it is possible to create stearic acid through hydrogenation) and it is found in many of the natural foods you likely eat regularly including poultry, fish, meat, eggs, butter, milk products, grains, cocoa, coconut and many others. Stearic acid, when natural and not the result of hydrogenation, is actually considered one of the healthier saturated fats as it is one of the preferred fats as fuel for the heart and it can convert to oleic acid in the body, the healthy monounsaturated fat found in olive oil.
Magnesium stearate is a compound which incorporates stearic acid with a magnesium ion. According to Wikipedia, the resulting compound is generally considered safe for human consumption, although the material safety data sheet says exposure to large amounts (like those only found in the processing of the chemical, never the small amounts you'd find as food additives) can lead to skin irritation and liver toxicity. You may actually encounter this compound every time you bathe yourself - magnesium stearate is one of the components of those bathtub rings found in homes with hard water as soap reacts with the minerals in the water forming soap scum.
So why add this stuff to vitamin supplements? Magnesium stearate has a lubricating property that keeps the elements in vitamin supplements from sticking to the processing equipment or from clumping together. According to Byron Richards, nutritionist and operator of Wellness Resources, having a substance included in the processing of supplements is vital in ensuring the right quantity is actually getting into each supplement and not sticking to the machines or clumping to their neighbors. Without magnesium stearate, Richards says "certain active ingredients may otherwise adhere to machine parts and not get into your capsules in the desired amounts or at the stated dosage."
So the substance is useful, but is it harmful? This is where the debate comes in. Some supplement companies who do not include magnesium stearate have begun to demonize the substance, claiming it is hydrogenated, toxic and immunosuppressive. Again, Richards says, "bad mouthing magnesium stearate is nothing more than a sales pitch. It is extremely irresponsible. A review of the product quality of the companies making such claims often leaves much to be desired."
On the other side of the argument is Dr. Mercola, who says, "vitamin manufacturers are seriously conflicted and HIGHLY motivated to defend their use of [magnesium stearate]. They just are unwilling to invest the extra time effort and energy to protect people. Tragic. But fortunately everyone has a choice and if you vote with your pocketbook you can motivate them to change their practice and make their supplements safer for you and everyone else."
The claim that stearic acid suppresses the immune system is unfounded. As Richards points out, the study they're quoting actually has nothing to do with magnesium stearate in supplements but is actually a study on the effectiveness of a mixture of stearic acid, diatomaceous earth and bovine serum albumin as an immune suppressant for transplant patients. Although the title of the study "Molecular basis for the immunosuppressive action of stearic acid on T cells", sounds ominous, the study itself has nothing to do with magnesium stearate or even stearic acid itself. Studies on the saturated fat stearic acid have never reported it to have a negative effect on the immune system.
This fact alone makes me question the validity of the charges against magnesium stearate. The claim that it is the product of hydrogenation is also questionable. Stearic acid is a naturally occurring fatty acid, but it may also be created through hydrogenation. I couldn't find definitive evidence that magnesium stearate is created using hydrogenated oil or not. It is unlikely that animal sources, which would likely already be saturated, would be hydrogenated but plant sourced magnesium stearate may or may not be. It may be up to the individual supplement company to source their magnesium stearate from companies not using hydrogenated oils in its production, but again, I'm not sure of this.
I wrote to David Rowland, nutritionist and operator of CNCVitamost supplements, to ask him about magnesium stearate in supplements. "The Merck Index (10th ed.) states that stearic acid occurs as a glyceride in tallow and other animal fats and oils, as well as in some vegetable oils – and that it can also be prepared synthetically by hydrogenating cottonseed and other vegetable oils. Merck doesn't state that all stearic acid is made by hydrogenation, only that some of it can be. Certainly, no responsible manufacturer of vitamins would use any hydrogenated product as a raw material – it would be counterproductive to the intended use of the product."
But alas, I have yet to find what I consider to be a truly definitive answer on the subject. I personally haven't changed my supplement taking behaviour as a result of what I've found researching this answer. Perhaps Richards sums it up best, "there is no human evidence or study that shows magnesium stearate is in any way harmful. To the contrary, its safety is well recognized throughout the industry." I leave it up to you to decide.

Jadi saya pikir karena tubuh itu unique, maka sangat tergantung pada tubuh ybs, n bagaimana reaksinya.
Yg jelas karena bahan ini adalah minyak n minyak adalah asam, maka dlm jumlah tertentu akan menaikan kemampuan tubuh utk memetabolismekannya, jadi yg paling baik adalah menggunakan supplemen secukupnya bukan menggantikan makanan yg ada sehingga tubuh pun secara natural bisa memproses nya dg baik n benar.
Sallam,
