Curcumin (Meriva)

 Curcumin is the orange pigment in turmeric (a primary ingredient in curry).  It is a potent antioxidant and NRF2 activator that offers numerous health benefits, including supporting healthy joints, liver, the GI and cardiovascular system, and it helps to maintain the body’s normal inIammatory response.


A thorough review of curcumin is forthcoming. In the meantime, please review the section below regarding a recommended curcumin product, Meriva. At the bottom of this page there are links to many journal publications that explore the multiple potential benefits of curcumin.

Meriva Product Description

Meriva-500 is a unique, patented curcumin product. People throughout Asia have benefited from the healthful effects of curcumin for centuries. Curcumin is the orange pigment in turmeric (the primary ingredient in curry), and is a potent antioxidant that offers numerous health benefits, including supporting joint health and hepatic, GI, and cardiovascular function, by helping to maintain the body’s normal inIammatory response.*


Whether taken as a supplement or from food, curcumin is generally poorly absorbed into the bloodstream. In conjunction with Indena S.p.A., the worldwide experts in botanical extract technology, we have uncovered the key to curcumin absorption – phytosome technology. Meriva curcumin phytosome is a unique curcumin extract that is signiVcantly better absorbed than other curcumin extracts.*


Phytosomes are plant extracts bound to phosphatidylcholine (PC), an essential component of human cells. Our bodies can make PC, but we can also get it from food or supplements. When taken orally, PC is very well absorbed. The scientists at Indena found a way to attach a curcumin extract to PC for superior absorption, resulting in Meriva. When you take Meriva your body absorbs the PC and the attached curcumin, resulting in more curcumin reaching the cells that can beneVt from it.*


A 2007 single-dose pharmacokinetic animal study demonstrated Meriva’s superior bioavailability, compared to ordinary curcumin.* The results demonstrated a >20-fold increase in absorption of curcumin from Meriva versus a standard curcumin preparation.* In addition, a 2010 three-month clinical trial demonstrated 1,000 mg of Meriva-SR per day helped maintain healthy C-reactive protein levels and promoted healthy joint comfort and mobility.* Furthermore, a 2010 randomized, single-blind, crossover human study revealed total curcuminoid bioavailability, as evaluated by the plasma area under the curve (AUC), to be 29-fold higher for Meriva than for the conventional standardized curcumin extract.*


Several studies have illustrated curcumin’s hepatoprotective effects, leading researchers to suggest its use in protecting the liver from exogenous insults from environmental toxins.* Curcumin also has the capacity to increase both the Iow and solubility of bile.* Curcumin’s hepatoprotective effects are due in part to direct free-radical scavenging; but curcumin also enhances the body’s natural antioxidant system, which increases glutathione levels, thereby aiding in hepatic detoxification and inhibiting nitrosamine formation.*


Drug Interactions with Curcumin

While the clinical significance has not yet been established, curcumin has been shown to inhibit P-gp, a transporter that affects blood levels and central nervous system levels of certain drugs. As a result of this inhibition, it may be possible that curcumin can decrease blood levels but at the same time increase central nervous levels of fentanyl, morphine, methadone and possibly oxycodone. This could result in either increased or decreased therapeutic effect and/or side effects. When taking curcumin while also taking these medications, caution should be emphasized by monitoring for changes in responsiveness to the medications and it may be necessary to reduce the dose of these medications to avoid side effects.
