Doctor Trusted Quality
There are several brands of supplements considered to be Doctor-Trusted-Brands which have pharmaceutical-grade ingredients. These supplement brands go above-and-beyond the call of duty to adhere to very rigid manufacturing guidelines  required by the FDA to be able to be trusted by healthcare practitioners around the world. These supplement brands will also be free of Gluten, Soy, Nuts, Fish, Shellfish, Dairy, Wheat, and many other common allergens. To skip to any particular section, you may click one of the following supplement brands:
Products such as Fish Oil, or Lactobacillus Probiotics will sometimes contain one of these major allergens, but they are required by law to be clearly listed on the label . These products are also produced on specialized manufacturing equipment, and will not share the same manufacturing facility as products containing these allergens. Larger companies, such as store brands, are often unable to offer this extra degree of purity, and you will see disclaimers on the label similar to ‘This product was manufactured in a facility that also produces…’ which doesn’t necessarily mean that supplement brand is low quality—but usually means its not pharmaceutical grade quality.
