Dietary Supplements - What the Industry Does Not Want You to Know

Stearates found in supplements are hydrogenated fats such as magnesium stearate, stearic acid and calcium stearate. They are made by hydrogenating cottonseed or palm oil and are used throughout the supplements industry as lubricants; they are added to the raw materials so that machinery will run at maximum speeds.

Stearates coat every particle of the nutrients, so the particles will flow rapidly. This ensures that production schedules will meet profit targets. These substances decrease the absorption of nutrients; in a published study, the percent dissolution for capsules after 20 minutes in solution went from 90% without stearates to 25% with stearates. Individuals with impaired digestion may have particular difficulty absorbing nutrients coated with stearates.

According to Udo Erasmus, in his book Fats and Oils, cottonseed oil has the highest content of pesticide residues of all commercial oils. In the hydrogenation process, the oil is subjected to high heat and pressure in the presence of a metal catalyst for several hours. According to Erasmus the resultant stearates contain altered molecules derived from fatty acids. The metal catalyst may also contaminate the stearates produced.

How Much Hydrogenated Lubricant Oil Are You Getting With Your Supplements?

Up to 5% of the average 500 mg capsule or tablet is magnesium stearate. That’s 25 milligrams. Suppose you take 8 capsules or tablets a day. That’s 250 a month – or 6,250 mg of this hydrogenated oil, nearly one-quarter ounce. That works out to about 3 ounces of hydrogenated oil a year, from just 8 pills a day.

The sole purpose of using these oils is to make the machines run faster. Supplements can be made without them – it just takes more time, care and attention to detail. Our exclusive process yields absolutely pure supplements – no lubricants, binders, flowing agents, fillers, dyes or additives of any kind – only the pure nutrients.
