Most enteric coatings are safe and non-toxic but certain companies will opt to use the cheapest ones. Certain products also feature an enteric coating which controls the rate at which the ingredients are released into the digestive tract, thus protecting the contents inside from stomach acid.
Coatings also protect the nutrients inside the tablets from oxidizing and becoming less effective. It may also protect ingredients from heat or moisture. Coatings and GlazesĪ coating or glaze, such as gelatin, prevents the tablet from falling apart and can make it easier to swallow. Common flow agents include magnesium stearate, stearic acid, and silicon dioxide. In this situation flow agents would be necessary. For example saw palmetto is a very viscous and sticky substance that machines have problems handling. Flow agents are not always necessary, though in some cases they cannot be avoided. They prevent ingredients from clumping and sticking together and clogging the machinery. Flow Agentsįlow agents, such as lubricants and anti-caking agents, are added to supplements to help them get through the manufacturing process as efficiently as possible. Common binders include gelatin, magnesium stearate, cellulose, and calcium carbonate. Ingredients that bind supplements together may also add weight or to allow for the inclusion of a combination of very small amounts of active ingredients. Broken and jagged pills are uncomfortable to swallow. Without binders, a pill may break apart or crumble. Just like their name suggests, binders help to hold the ingredients in a supplement together. Common fillers include calcium, carbonate, and cellulose. Having fillers makes it easier to handle and take the supplement.
Some ingredients like biotin have dosages in the microgram range which are thousandths of a milligram. Supplement manufacturers use them because, without them, the pills can be tiny, difficult to handle, and nearly impossible to consume. FillersĬommonly referred to as bulking agents or carriers, fillers are used to increase the size of a tablet or capsule by adding substance. Here is a breakdown of what additives and excipients do and how they can affect your health. If they are present, then you will usually find them listed under “other ingredients” or “inactive ingredients” section. These additives do have a purpose which may be to act as fillers, binders, or flow agents. Many nutritional supplements contain additives or excipients.
