Silicon dioxide, Cellulose, Magnesium stearate, Stearic acid, Maltodextrin, and Tricalcium Phosphate in supplements

Silicon Dioxide

It’s a form of silica, the most abundant substance on Earth. This pure, pharmaceutical-grade silicon compound is insoluble and is not digested or absorbed in the intestinal tract. During manufacturing, it enhances the flow of powders and prevents material from forming clumps. This also insures an even distribution of nutrient components throughout the batch so that the products uniformly meet or exceed nutrient label claims.

The U.S. Food and Drug Administration (FDA) states that silicon dioxide is found all over the world. Not only is it the foundation of sand on beaches, in bodies of water and in deserts, but it is also found in drinking water, in plants and in animals. Therefore, it is naturally part of the foods we eat. No scientific research has found whether it is a necessary nutrient for our bodies, nor has research found any signs that it causes harm to the body. The rule goes that if supplements contain less than 2 percent of silicon dioxide, they are safe.


It is a pharmaceutical-grade, pure form of plant vegetable that helps to hold the tablet together. It is milled into an extremely fine powder to assist the product to meet USP standards for gastric disintegration and to enhance nutrient bioavailability.

Cellulose in your supplements is okay and virtually impossible to avoid. People get confused on this issue, because it is an indigestible fiber and therefore not ideal to ingest. But a tiny amount in a supplement is fine. Because the human body does not contain an enzyme to break down the structure of this carbohydrate, it is used to add bulk in the diet, which is necessary for proper peristaltic actions of the intestines.

Magnesium stearate / Stearic Acid

Magnesium stearate is a combination of stearic acid and the essential mineral magnesium. This vegetable-source compound is vital for keeping the tablet ingredients from adhering to equipment during the manufacturing process.

Stearic Acid is a natural fatty acid obtained from edible vegetable sources. It supports the flow of the product during manufacturing from initial mixing to final from, ensuring the ratio of nutrients is consistent from tablet to tablet, capsule to capsule and serving to serving. It also acts as a tableting aid and prevents tablet ingredients from adhering to production equipment.

Most people concerned about the tiny amount of stearic acid in a capsule actually consume far more from healthy food sources, safely. Meat, coconut oil and chocolate (cocoa butter) are particularly rich sources. Additionally, researchers do not consider stearic acid to be a lipid that is harmful to cardiovascular health.

Stearic acid is naturally present in many foods in far greater quantities than in supplements. Stearic acid is also the immediate precursor of oleic acid, an important fatty acid found in healthy olive oil.

Stearic acid is a waxy oil fraction that acts as a lubricant to fill capsules when a dry powdered ingredient (or ingredient mix) is uncooperative, based on issues involving density, stickiness, flowability under pressure, etc. It is also used as an ingredient that helps tablets hold together and break apart properly.

Stearic acid (also called Octadecanoic Acid) is one of the most common long-chain fatty acids, found in both natural animal and vegetable fats, known also by its structural description of being an 18-carbon chain fatty acid (18:0) with a chemical structure of C36H70MgO4. BioSynergy uses USP grade stearates tested to US Pharmacopeia standards; known as pharmaceutical grade, the highest purity.

The stearic acid and magnesium stearate that are sourced from vegetable oils obtained from palm and other natural sources. These ingredients are widely considered to be safe, and are suitable for vegetarians and vegans. An American Journal of Nutrition published review of beef’s effect on cholesterol reported that, “Beef products are the most common source of dietary stearic acid in the United States. Because beef fat is 19% stearic acid, the cholesterol-raising potential of beef is not as great as predicted by its total saturated fatty acid content…Data suggest that lean beef is no more hypercholesterolemic than chicken or fish and, therefore, lean beef need not be eliminated from cholesterol-lowering diets.”

Stearic acid is also one of the main fats in cocoa butter, and this particular fatty acid is considered safer than others present in cocoa butter. A report from the University of Texas Southwestern Medical Center confirmed this: “It has been known for some time that cocoa butter, although rich in saturated fatty acids, does not raise total serum cholesterol concentrations as much as expected from its total saturated fatty acid content…In a recent experiment cocoa butter did not raise LDL cholesterol as much as predicted by its total saturated fatty acid content.” Researchers at the University of Nebraska noted, “The observation that dietary stearic acid does not raise plasma cholesterol concentration is well documented, although the regulating mechanisms are not completely understood…”

The USDA cites this study regarding the use of magnesium stearate as a functional aid in the manufacture of tablets: “Stearic acid is the predominant fatty acid in triacylglycerols of beef fat and coconut oil (present as the ester). As the magnesium stearate in tablets, it helps keep the solid ingredients from falling apart in the bottle, and it also enables the tablet to break apart and release the active ingredient when the tablet is swallowed.”


Derived from rice and corn starch, and used in tablet formulations to allow even distribution and/or mixing of active ingredients. The safety and efficacy of this component is well established.

Maltodextrin is a complex carbohydrate that greatly helps individuals perform better and last longer to cope with the demands of heavily strenuous activities. Despite being a carbohydrate, it functions more by rapidly degrading the enzymatic process. Maltodextrin supplements are usually added to beverages in order to quickly replenish carbohydrate stores that may have been depleted during exercise. Maltodextrin provides 4 kilocalories per gram just like any other carbohydrate. The ingredient is a very convenient energy source that facilitates rapid delivery and absorption of important nutrients by muscle tissues. Muscle glycogen can instantly be replaced during or after exercise.

Maltodextrin is derived from cornstarch and is very easily digestible. The starch is initially cooked. Acids and/or enzymes are then added to break the starch into smaller polymers. The process is highly similar to what occurs inside the body when digesting carbohydrates. Some forms of maltodextrins are polymers of dextrose that are also referred to as glucose polymers coming in the form of dried powders. These do not contain much fat, fiber or protein although some products are highly known for having soluble fiber and is very useful in reducing fat and excess weight. Most products also do not add vitamins or flavors.

Tricalcium Phosphate

Tricalcium Phosphate allows even distribution and mixing of active ingredients and aids in tablet compression. It is considered a good source of dietary calcium.

It is a pharmaceutical-grade, pure form of both calcium and phosphorous. Both compounds are regularly found in nature. Calcium and phosphorous are essential for proper human bodily function and highly involved in healthy bones and teeth as well as blood and intracellular health.
