    Pure Encapsulations is a trusted brand known for high quality supplements produced in NSF-GMP facilities in Massachussets which exceed the standards of the United States Pharmacopeia (USP). The Pure Encapsulations brand is known for meeting label claims and having a high level of quality assurance, but tend to be more expensive than other supplements that also meet label claims. Many doctors endorse their products. Their manufacturing process is so good that they welcome you to visit their plant and see how their products are made. Pure Encapsulations also ensures that their suppliers provide premium raw ingredients. All of their products are free from wheat, gluten, egg, peanuts, coatings, shellacs, GMOs, magnesium stearate, trans fat and hydrogenated oils, artificial colors and flavors, fillers and preservatives. This is really great for those that have allergies. They base a lot of their formulas on research.

    Pure Encapsulations maintains that they hold a stringent testing policy:

    • Raw materials are tested for identity, potency, microbial contaminants, heavy metals (including mercury, arsenic, cadmium, and lead), 32 solvent residues, and allergens
    • Herbal ingredients are tested for 70 different pesticide compounds and essential fatty acids and fish/krill oils are tested for dioxins, furans, PCBs, and other agents
    • Fish oils are tested for oxidation, PCBs and PCB-like compounds, dioxins, and furans
    • They also test for any specific contaminants known to be potential adulterants (for example, they test grapefruit seed for potential preservative contaminants)

    Pur Encapsulations' testing is done through high-quality, third-party independent laboratories, such as Silliker, Eurofins, Intertek, and Advanced Laboratories, which are considered the gold standard in the industry.

    At Pure Encapsulations, probiotics are verified with DNA testing. Our products, as well as our manufacturing and testing procedures, are thoroughly inspected twice annually by the NSF (a very reputable organization that inspects products for compliance with the FDA GMPs)

    Selenium helps target a weak immune system, infections, cancer cells, inflammatory problems, and abnormal thyroid function [1-7]. It also enhances heart health, brain health, and the body's natural antioxidant activity, among other benefits [1-12].
    Enhanced Immunity, heart, brain, and thyroid health [1-12]
    Selenium functions as an antioxidant and it also maximizes the activity of an enzyme called glutathione peroxidase, which acts as an antioxidant; in doing so, selenium supplementation strengthens immune system function [1-3]. The increased antioxidant activity enhances the body's ability to protect cells (e.g., red blood cells, breast, lung, esophageal, gastrointestinal, and prostate cells) from cancer-causing damage [1-12]. Selenium also improves thyroid function and heightens the body's release and use of thyroid hormones [4-7]. In addition, it heightens brain health (e.g. memory) and helps delay mental decline [9-10].
