Vital Nutrients' mission is to manufacture superior quality nutritional supplements that exceed both industry and government standards and provide clinically effective results. They provide over 200 science-based and clinically effective products. Vital Nutrients uses independent U.S. ethical laboratories to test all raw materials and finished products. Each raw material is tested, regardless of origin, for purity and potency. All finished products are tested through a real-time stability protocol for expiration date validation. They are an FDA-inspected facility that exceeds FDA cGMPs, and a member of the NPA.

Vital Nutrients is known as the leader in quality in the nutraceutical industry. They are an American-owned and operated company dedicated to manufacturing high-quality nutritional supplements that promote health, wellness, and vitality. Their products are trusted by hospitals, healthcare practitioners, and consumers worldwide.

While all-natural product companies claim to have the best quality, most are not completing all the steps required to comprehensively ensure that quality and purity standards are consistently met for every batch of product. Vital Nutrients' Quality program far exceeds both FDA and industry standards, with all manufacturing occurring at their strictly-controlled state-of-the-art, FDA-inspected facility in Connecticut.

Key elements of Vital Nutrients' Quality Program include no skip lot testing, where they test every batch of raw material and finished product to ensure potency, purity, and authenticity, and the use of only U.S. independent labs that follow scientifically valid analytical methods and ethical lab practices to verify their materials.

In addition to authenticity, potency, and stability, Vital Nutrients tests for microbiology, chemical solvent residue, heavy metals, aflatoxin residue, rancidity of oil products, and dioxins, dioxin-like compounds, and PCBs in fish oils, as well as product-specific tests.

Aller-C is a potent and effective combination formula that uses natural organic liposomal vitamin C. Isoquercitrin and Hesperidin (from Citrus Bioflavonoids) have been shown to be two of the most useful and physiologically active flavonoids. This formula can be used for maintaining and supporting proper levels of enzymes and physiologic factors necessary for normal respiratory and sinus function, helping you to feel more clear during seasonal challenges without the drowsiness associated with many allergy medicines.

Aller-C supports respiratory and sinus relief from seasonal allergy symptoms using a unique blend of vitamin C, bioflavonoids, high-potency bromelain, and isoquercitrin for full-spectrum immune function support. It contains isoquercitrin, featuring the benefits of a quercetin supplement with superior absorption and bioavailability, to help promote cellular antioxidant defenses and a normal histamine response.

Vital Nutrients supplements are manufactured in their allergen-free, NSF-certified Middletown, CT facility. Their rigorous quality assurance program includes third-party independent laboratory testing of raw ingredients and finished products for purity and potency to ensure what's on the label matches what's in the bottle. Vital Nutrients was founded 30 years ago by practitioners who set out to make a positive and lasting impact on the health of people and planet, and their premium line of clinically relevant, pure, clean-label formulas is trusted by healthcare practitioners and health-conscious consumers worldwide.
