The Reason Why We Do Not Use Fillers and Other Additives

The Reason Why We Do Not Use Fillers and Other Additives

Most of the nutritional supplements you will find in the market today contain more than just active ingredients. Many of the nutritional companies will use what is called, "flow-agents" inside the capsules for the sole purpose of keeping the ingredients from sticking to equipment during mixing and compression. By using these types of ingredients, not only this will make manufacturing process faster and smoother, it will reduce manufacturing costs. When searching for a nutritional supplement, it is essential to avoid the following dangerous ingredients that can be potentially harmful to your health:

Magnesium Stearate

The role of magnesium stearate used in nutritional supplements is to act as a lubricant to prevent tablet and capsule from sticking to the machinery. This ensures that production machinery can operate at maximum speed. Magnesium stearate is formed by adding a magnesium ion to stearic acid. The compound has lubricating properties, which is why it's often used in the making of supplements, as it allows the machinery to run faster and prevents the pills or capsules from sticking to each other.

However, previous research has shown that stearic acid suppresses T cells, the natural killer cells, which are a key component of the immune system. According to that study, stearic acid causes the collapse of cell membrane integrity, an effect that was found to be time and dose dependent, in which, ultimately can destroy cell function.

If you're taking a supplement, making sure it's a high quality that does not include potentially harmful fillers and additives such as magnesium stearate. In its report on magnesium stearate, the National Institute of Health (NIH) poses the threat of magnesium overdose in impairing neuromuscular transmission and that it can cause weakness and diminished reflexes. Although extremely rare, the NIH reports that:

Thousands of exposures occur every year, but severe manifestations are very rare. Severe toxicity is most common after intravenous infusion over multiple hours (usually for pre-eclampsia), and can occur after chronic excessive doses, especially in the setting of renal insufficiency. Severe toxicity has been reported after acute ingestion but is very rare. Nonetheless, this report hasn't put everyone's mind to rest. Just a quick glance at Google, you will find magnesium stearate connected to a number of side effects such as:

Poor Intestinal Absorption

Because it's hydrophobic ("water loving"), there are reports suggesting that magnesium stearate can slow down the rate at which drugs and supplements are dissolved in the gastrointestinal tract. Directly affecting the ability of the body to absorb chemicals and nutrients, the protective nature of magnesium stearate can theoretically make a drug or supplement veritably useless if the body can't break it down properly.*

Stearic Acid

Stearic acid, which is also known as octadecanoic acid, is a saturated fatty acid. It is waxy in nature. The term 'stearic' is derived from the Greek word 'stear', which means 'tallow'. The salts and esters of this acid are known as stearate. It is made up of carbon, hydrogen, and oxygen atoms. Its chemical formula is C18H36O2 or CH3 (CH2) 16COOH. Although it is found in both animal and vegetable oil, it is more commonly found in animal fat compared to vegetable fat. Stearic acid is made by treating animal fat with water at a high temperature and pressure. This causes hydrolysis of triglycerides. It can also be obtained from the hydrogenation of some unsaturated vegetable oils.

Stearic acid is generally considered to be a low to moderate hazard ingredient. There have been claims that in slight amounts, stearic acid may lead to some types of cancer. There have also been concerns regarding neurotoxicity, organ toxicity, and irritation of skin due to its use. The concern for its possible carcinogenic effect steams from animal studies that have shown that it had some effects on the central nervous system, respiratory system, and skin, even when administered in very low doses. In fact, in vitro tests on mammalian cells were positive for mutation results. Since undesirable effects of stearic acid have been revealed in animal studies, it is advisable to avoid its use. A better alternative would be to use cosmetic products that are made from natural ingredients.*


Nearly all of the silica supplements are made with horsetail, though some contain silicon dioxide, which is found naturally in sand. Horsetail contains silicon, which forms into silica as the plant dries. While there is not much scientific evidence on the benefits of taking silica, it is sometimes recommended by herbalists for osteoporosis, urinary tract infections and brittle nails. Discuss silica's potential benefits and risks with your health care provider before taking it to minimize the rise of dangerous side effects. Because supplements don't have to get The U.S. Food and Drug Administration's approval, it's important to talk with your healthcare provider or an educated herbalist before taking silica.*

Horsetail silica supplements usually are safer than those that contain silicon dioxide from other sources, but it's important to determine what species of herb horsetail supplements include. The Equisetum ravens species of horsetail is safe for most people to take for short durations, but another species called, Equisetum palustre could be dangerous. This species is poisonous to horses. While there hasn't been much research done on the effects of Equisetum palustre in humans, it's best to use supplements only from week-known companies that use E. arvense.*

Medical Conditions

Silica can lower your blood sugar levels, which can be particularly dangerous if you have diabetes. Talk to your healthcare provider before taking silica if you have diabetes because your healthcare provider can help you decide on a safe dosage and form. Be diligent about monitoring your blood sugar levels if you take horsetail and notify your healthcare provider immediately if you notice your levels dropping. Don't use silica if you're pregnant or nursing to reduce any potential risks to your baby. Moreover, taking silica with chromium supplements or herbs that contain chromium, such as brewer's yeast and bilberry can increase your risk of chromium poisoning.*

Artificial Color and Flavors

It's without a doubt that artificial food coloring makes your foods more appealing and desirable. For most of food history, the dyes used were from natural sources, beet juice for red, turmeric for yellow, carrots for orange, etc... But for manufactures to maximize profit and lower costs, artificially coloring foods and drinks is the way to go. Unfortunately, the manufactures don't consider the harmful side effects that scientist have discovered.

Over the past few years dyes have been called into question for their damaging side effects. Recent scientific research has linked food dyes to a number of potential health problems, most notably certain types of cancer in animals and Attention Deficit Disorder (A.D.D.) in children. The U.S. Food and Drug Administration have acknowledged that artificial colors such as Red 40 and Yellow 5, trigger hyperactivity and behavioral problems with some children, yet they still allow it. It doesn't stop there. Each dye, through animal testing can be linked to different diseases. Just to name a few: kidney tumors, tumors of the urinary bladder, testes tumors, and immune system tumors.*

Unfortunately, these dyes draw kids away from nutritious foods and towards brightly colored processed products, like fruit flavored drinks and snacks. These foods and drinks are high in calories but low in nutrients. Keeping these dyes away from children is extremely important, especially during the developmental years when their bodies are particularly more sensitive.*
