Here is a quick look at those Other Ingredients and why you should not be taking these type of supplements.
Binders: A supplement must disintegrate rapidly for maximal absorption to occur. Tablet binders holds the ingredients together like glue and rarely break down completely. Your supplement must disintegrate to be of benefit.
Magnesium Stearate (a lubricant) In a study published in the journal Pharmaceutical Technology (April, 1985),stearates reduce the rate the capsule dissolves by 65% which may not dissolved in the appropriate section of the intestines as intended. It is also hard on the kidneys and liver to break down.
Titanium dioxide (colorant and filler) has recently been classified by the International Agency for Research on Cancer (IARC) as an IARC Group 2B carcinogen ''possibly carcinogen to humans''. It is widely used to provide whiteness and opacity to products such as paints, plastics, papers, inks, foods, and toothpastes.
Silicon dioxide (anti-caking) It’s really just sand and supposedly indigestible however there is speculation that taking large amount of supplements with silicon dioxide may cause Chronic Fatigue Syndrome. Similar to what women with silicone breast implants (which has a significant amount of silicon dioxide it them) were experiencing. Worldimage.com recommends not consuming silicon dioxide in pills because it is used to make glass and electrical components and it might be "carcinogenic to humans," according to the International
Artificial colorings can cause allergies and other nasty health problems like ADD and ADHD. They usually have the terms D & C or FD & C (D= drug, C= cosmetic, F= food). E.g. FD & C Yellow #5, FD Red #2 etc.
Sweeteners are common in supplements. They make highly soluble, bitter tasting nutrients more palatable. Liquid vitamin products contain large amounts of sweeteners. Sucralose pre-approval research has shown to contribute to serious chronic immunological or neurological disorders. Sucralose has been approved by the FDA for use in supplements! We just don't know yet!
Sodium Benzoate:A common preservative and flow agent used in supplements. Has GRAS (generally recognize as safe) status in the U.S. but is a dubious preservative.
Propylene Glycol:A tablet binder - maintains moisture to stop tablets crumbling apart (friability). Also used to make anti-freeze, de-icing solutions, cosmetics and as a solvent in: food colors, flavors, paints/plastics industry. Excessive exposure damages kidneys, heart, pancreas and nervous system.
Aluminum silicate (talc):A cheap non-food grade lubricant used in the manufacturing process. Considered by some experts to be a neuro-toxin which causes Alzheimer’s disease. May lead to digestive or absorptive problems.
The most common tablet binder is probably cellulose (a plant fiber usually from pine trees in a similar form to paper) or a derivative of it so you’re bound to see “cellulose” on your label. Personally I don’t like to ingest paper and pay for it as well.
