Meriva® is a patent-pending delivery form of curcumin and has been shown to improve the bioavailability of curcuminoids by up to 30-fold compared to traditional forms. Studies have demonstrated that Meriva® can reduce stiffness, muscle soreness, improve physical function, and promote liver health and overall quality of life. Additionally, a long-term study has shown Meriva® to support ocular health and confirm its excellent safety profile.

Product Overview
  • Supported by over 35 human trials involving more than 2,000 subjects Meriva® Curcumin Phytosome® stands out as the real The Life Guardian™ you can rely on.
  • From joint to eye health or liver to kidney, Meriva® helps users to maintain high quality of life and support the physiological “detoxification” processes. It offers lifelong antioxidant activity so that your body’s natural response does not turn into low-level chronic inflammation, also known as the silent killer.
  • Moreover, long term studies have highlighted that Meriva®’s top-grade formulation leads to outstanding tolerability and safety even for prolonged use.
  • Today, there’s no complete healthy life maintenance program without Meriva®.

Technical Details & Test Data

Meriva® into Action
  • Meriva® Curcumin Phytosome® is effective thanks to the synergic power of 3 major curcuminoids (i.e., the active ingredients naturally present in turmeric) it contains in the same proportions expected in Nature.
  • And there’s more: Meriva® is the formulation with the highest levels of demethoxycurcumin (DMC), the most powerful curcuminoid. 
  • Thanks to this molecular profile composition and its unique Phytosome® delivery system, Meriva® shows effectiveness in particular for joint & bone and kidney health.
Scientific Evidence

MERIVA® is the 100% natural food grade delivery form of curcumin utilizing Indena proprietary Phytosome® technology, based on dietary-grade adjuvants (lecithin), able to optimize the bioabsorption of the extract.

MERIVA® is the most studied and documented curcumin bioavailable formulation.

MERIVA® pharmacokinetic studies demonstrated significant absorption benefits:

  • Improved plasma Cmax and AUC of curcuminoids near 30-fold over the standard turmeric extracts.

MERIVA® is supported by more than 35* human trials demonstrating effective support in multiple health conditions:

  • Improved health status in subjects with non-alcoholic fatty liver disease (NAFLD).
  • Improved bone density in asymptomatic subjects with a bone density condition
  • Improved strenght and physical performance, preventing loss of lean body mass in elderly population
  • Attenuated muscle soreness from oxidative stress and inflammation associated to continuous exercise
  • Healthy blood vessel function support
  • C-Reactive Protein (CRP) levels: minus 16-fold
  • Social and Emotional Index (SEI) score resulted in a greater than 3-fold improvement
  • Decreased WOMAC score measuring excercise related pain, stiffness and physical function

Two recent studies highlighted MERIVA® efficacy in supporting kidney health:

  • The University of Chieti-Pescara evaluated the supplementation of MERIVA® in subjects with temporary kidney dysfunction (TKd) and increased oxidative stress levels. The clinical evidence showed that albuminuria decreased in all subjects due to its antioxidant properties and oxidative stress level was positively affected after 4 weeks
  • The University of Milan, focused its study on chronic kidney disease (CKD) subjects: MERIVA® significantly leveled plasma pro-inflammatory mediators and lipid peroxidation.
  • Regarding gut microbiota, after 6 months of curcumin supplementation it was observed a more balanced composition of the intestinal microbial population.
