The use of dietary supplements has increased considerably in recent times—attributed largely to a growing awareness of potential side effects from synthetic, prescription medications. Proper supplementation can help fill nutritional gaps in one’s diet, as well as address very specific imbalances within the body. With this increase in usage has come the expected increase in supplement brands to choose from. While many manufacturers may sell a supplement labeled with the same ingredients, there are certain trusted brands offering pharmaceutical grade supplements that are trusted and used by healthcare professionals. These high quality brands offer pure ingredients free of fillers, additives, contaminants, and are guaranteed to contain the ingredients listed on the labels—and are considered to be pharmaceutical grade supplements.
Supplements are regulated by the FDA as food products, and are subject to much less scrutiny of efficacy before hitting the store shelves. Clinical trials aren’t require as are with prescription medication, which allow many manufacturers to get away with adding fillers and unwanted materials. What this means is, that while you may have much easier access to supplements than prescription medications, you must pay much more attention to the quality of product you are getting.
Luckily, there are quite a few brands available now that are doctor-trusted supplements, and adhere to the guidelines pharmaceuticals manufacturing. You typically get what you pay for with supplements; the more expensive brands being the most pure, and the cheaper brands using extra fillers, questionable inactive ingredients, and overall less pure ingredients.
