Curcumin, the anti-inflammatory quintessential ingredient of turmeric, is very poorly absorbed by the gut in part due to its low solubility in water.
Indeed, a study conducted in the universities of Michigan and San Diego shows that the simple curcumin powder is poorly assimilated into the blood to doses up to 12 grams per day (more than a tablespoon of powder). Of the 24 study participants, only 2 people had their curcumin content in the blood increase albeit at levels insufficient to achieve significant benefits (Lao 2006).
To overcome the very low uptake of curcumin, a group of researcher at the University of California Los Angeles (UCLA) has developed the formulation of Optim Curcuma. The secret of Optim Curcuma lies in the Longvida® Solid-Lipid Curcumin Particle (SLCP™) patented process.
This process consists in covering in a precise way the curcumin with natural lipids to form small particles and thus improves by at least 65 times the absorption of curcumin in the body. Clinical and in vitro studies tests were conducted with the formulation of Optim Curcuma.
These studies have shown that curcumin has a wide range of effects, especially on inflammatory responses, with doses as low as one capsule a day (Cox, 2014; Di Silvestro 2012; Nahar 2014).
