Curcuzen® 100% Natural Curcumin

Are you getting what you expect from your curcumin product?

Curcumin is now one of the most in-demand botanical ingredients in the current nutritional market place. Derived from turmeric (Curcuma longa), the ancient Ayurvedic herb has a long history of use in both culinary and medical tradition, lauded for its antioxidant and anti-inflammatory effects. Growing research now notes its potential to support healthy function of the heart, brain, joints, respiratory system, blood glucose metabolism, the digestive system and liver as well as enhance physical performance and mood.

Princeton Vitamins is proud to announce its new 100 percent natural curcumin product Curcuzen™ with 95% curcuminoids from raw turmeric sources.

When it comes to curcumin, natural is important because the growing demand for the ingredient has prompted concerns about adulteration with synthetic curcumin that is designed to mimic natural curcumin in identity tests, but which has not been tested for safety or pharmacological activity.

How Curcuzen is made

Curcuzen® is prepared with top-to-bottom control from the extraction of the root and purification of the curcumin to final packing in our facility. Curcuzen is made using a proprietary branded curcumin from Bioactives American. The curcumin is authenticated using the 14C (radio carbon dating) method—the only approved method for authenticating natural curcuminoids. Curcuzen is tested and analyzed at the Center for Isotope Studies at the University of Georgia as 99 percent naturalized (13.91 dpm/g carbon compared to 14.0 dpm/g carbon).

Scientific studies

Research is building on the importance of curcumin’s health benefits. Its anti-inflammatory properties have long been documented.1 Although many questions remain about its effects on other systems, here are a few intriguing studies about its beneficial properties:

Most recently a 2017 study noted the cardioprotective potential of curcumin2. Looking further back, a growing body of research also noted its promising potential for supporting brain health3,4 and healthy joint function.5
