PROPER NUTRITION CAN BE HARD to manage in today’s world of sub-par food options, especially if you live on-the-go. Fortunately, you can often times make up the difference by proper nutritional supplementation with vitamins and other natural compounds such as Calcium, Magnesium, or Fish Oil. It is important to purchase products from the best supplement brands which are trusted among doctors and healthcare professionals to provide the purest, most high-quality supplements available.

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 a section for any particular section, you may click one of the following supplement brands:

Products such as Fish Oil, or Lactobaccillus Probiotics will sometimes contain one of these major allergens, but they are required by law to be clearly listed on the label [5]. 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.

The Best Supplements Support Natural Balance

More and more people are starting to use vitamins, supplements [6] and other forms of alternative therapy—such as detoxing in an infrared sauna—to help treat such conditions as obesity, menopause, depression, anxiety, food intolerance, Celiac’s Disease, and many, many more chronic health conditions. Many of the factors standing accused of contributing to this global health crisis, such as GMO foods, synthetic food additives, and toxic residues are in many supplements found in stores. In many cases, these ingredients aren’t required by law to be listed on supplement labels—which is why it is so important to buy from Doctor Trusted supplement brands.

More and more people are starting to use vitamins, supplements and other forms of alternative therapy

I have personally taken products from each and every one of these manufacturers, and can attest to their quality, potency, and purity. To get a better understanding of the considerations made when qualifying a supplement as “pharmaceutical grade,” check out our article Pharmaceutical Grade SupplementsNow, without any further ado, and a much better perspective on why it is important to purchase quality supplements; here is the list of the best supplement brands—with the pros and cons of each one. Do keep in mind that any of these brands are almost certain to be much better than any product you’ll find in stores—even your local health food store—and are often only available for purchase online, or through a licensed healthcare practitioner.
