Magnesium Stearate ( all stearates)


magnesium stearate

Magnesium stearate as well as all other stearates should never be used in a nutritional supplement but is commonly done so.
Magnesium stearate, stearic acid and ascorbyl palmitate, are all made by hydrogenating cottonseed or palm oil.  First cottonseed oil has the highest content of pesticide residue of all the commercial oils and now most of the non-organic cotton is produced via GMO. Now one has to question the use of a hydrogenated oil in our supplements when the health industry is telling people to avoid hydrogenated oils in their diet ( and correctly so)
In the hydrogenation process, the oil is subjected to high heat and pressure in the presence of a metal catalyst (which may contaminate the end product) for several hours, creating a hydrogenated fat. (As you will learn in the newsletters on liver/gallbladder flushes, hydrogenated oils are at the root of the liver producing liver and gallstones which need to be eliminated to achieve real health) and should not be added to our supplement regimen.
The purpose of the use of stearates is that they are added to the raw materials as lubricants so that the production machinery will run at maximum speeds and these fatty substances coat every particle of the nutrients so that the particles will flow rapidly.
According to an artile published in the Journal Immunology back in 1990, stearates pose a problem with the suppressing the action of T-cells and T-cells are a key component of our immune system.

Consider these facts:

‚Äʬ†¬† ¬†Magnesium stearate uses include:¬† ammunition, dusting powder, paint and varnish drier, binder and emlusifier.

‚Äʬ†¬† ¬†Companies that manufacture and transport magnesium stearate must file a Material Safety Data Sheet with the EPA because concentrated magnesium stearate is classified as a hazardous substance

‚Äʬ†¬† ¬†Under the section titled "Human Health Data" it states that "Inhaling Magnesium Stearate may irritate the respiratory tract" and acute ingestion may cause gastroenteritis.

‚Äʬ†¬† ¬†Under the heading "Regulatory Information" it states that magnesium stearate is hazardous under the criteria of the Federal OSHA Hazard Communication Standard" - you can see this information at the web site:¬†

‚Äʬ†¬† ¬†Supplement manufacturers pass off magnesium stearate as a benign form of magnesium. They try to claim that small amounts of these substances do you no harm.¬† Really? They ignore the fact that this harmful substance bio-accumulates over time and causes immune suppression. Do you really want to ingest any of this?

‚Äʬ†¬† ¬†Also consider that usually, the magnesium stearate accounts for up to 5% of the supplement tablet or capsule. Multiply that by the number of capsules or tablets you take per day and over time becomes quite a bit. For example only 8 capsules or tablets per day will result in 6 ounces of this oil within 12 months.

‚Äʬ†¬† ¬†Dr Klinghoffer from Seattle, states that magnesium stearate stimulates the body to produce biofilms.
it is prudent to throw away any nutritional supplement that has toxic tagalongs and especially magnesium stearate in it and avoid buying any of them in the future.

PR Labs products do NOT use magnesium stearate.
