Absorb 95X More Curcumin*
Biotest's Micellar Curcumin™ formula contains solid lipid curcumin particles that produce 95 times more free curcumin in the bloodstream than highly pure, standardized curcumin (Gota VS et al, 2010).*
That's a bold claim. Fortunately, the formula's solid lipid curcumin particles are backed up with convincing science, invented by neuroscientists at UCLA, funded by the University of California (Oakland) and the Federal Government, supported by peer-reviewed research on humans, and patented (9,192,644).
Curcumin's Great Potential
Medical researchers have had a longtime interest in curcumin for its positive effects on neurological tissues, cardiovascular health, inflammation, metabolism, insulin sensitivity, and sexual health.
But the frustrating problem has always been its poor bioavailability. Curcumin isn't soluble in the gastrointestinal tract, making it difficult to absorb, and it's vulnerable to something called glucuronidation, which converts curcumin into what amounts to inactive waste.
An example of curcumin's poor bioavailability is a study where patients were given a whopping 3.6 grams of ordinary curcumin a day (about 7 capsules). Even at those large doses, detectable blood and liver levels of free-form curcumin were almost non-existent (Garcea, et al, 2004).
Biotest previously addressed this bioavailability problem by taking a super-pure curcumin extract and combining it with piperine, which is a known glucuronidation inhibitor. The curcumin/piperine formulation was, in its time, the best science could do, but as with most things, science progressed. Enter Biotest's Micellar Curcumin™ solid lipid curcumin particles.
Not only does the Micellar Curcumin™ formula increase blood concentrations of curcumin 95 times more than native curcumin, it also has a half-life that's extraordinarily long. This means you only need to take one dose per day.
What's So Special About Micelles?
The big hurdle in making an effective, bioavailable curcumin product is to protect it from glucuronidation and get enough active compound absorbed into the bloodstream to affect target tissues.
Neuroscientists at UCLA figured it out. After 10 years of research, development, and endless tweaking, they produced what they call Solid Lipid Curcumin Particle Technology. This technology is what Biotest uses in its Micellar Curcumin™ supplement.
In simplest terms, the process consists of coating curcumin with lipids to form micelles and drying the mixture into solid lipid particles. Once the particles are consumed, they form curcumin micelles that protect the curcumin from glucuronidation and are easily absorbed into the bloodstream through the lymphatic system.
An Easy Choice
If you want the most benefits from curcumin, Biotest's Micellar Curcumin™ formula is an easy best choice. Its solid lipid curcumin particles are backed up with over 50 human, pre-clinical, and review papers in publication, many of which are referenced and synopsized below.
Studies On Solid Lipid Curcumin Particles:
Gota VS et al. Safety and pharmacokinetics of a solid lipid curcumin particle formulation in osteosarcoma patients and healthy volunteers. J Agric Food Chem. 2010 Feb 24;58(4):2095-9. doi: 10.1021/jf9024807. – Curcumin is the lipid-soluble antioxidant compound obtained from the rhizome of Curcuma longa Linn, also known as turmeric. Curcumin targets multiple chemotherapeutic and inflammatory pathways and has demonstrated safety and tolerability in humans, supporting its potential as a therapeutic agent; however, the clinical literature lacks conclusive evidence supporting its use as a therapeutic agent due to its low bioavailability in humans. The purpose of this study was to quantify plasma levels of free curcumin after dosing of a solid lipid curcumin particle (SLCP) formulation versus unformulated curcumin in healthy volunteers and to determine its tolerability and dose-plasma concentration relationship in late-stage osteosarcoma patients. Doses of 2, 3, and 4 g of SLCP were evaluated in 11 patients with osteosarcoma. Plasma curcumin levels were measured using a validated high-performance liquid chromatography method. The limit of detection of the assay was 1 ng/mL of curcumin. In healthy subjects, the mean peak concentration of curcumin achieved from dosing 650 mg of SLCP was 22.43 ng/mL, whereas plasma curcumin from dosing an equal quantity of unformulated 95% curcuminoids extract was not detected. In both healthy individuals and osteosarcoma patients, high interindividual variability in pharmacokinetics and nonlinear dose dependency was observed, suggesting potentially complex absorption kinetics. Overall, good tolerability was noted in both healthy and osteosarcoma groups.
