Regular versions of curcumin have huge bioavailability issues. Sure, studies involving rats show acceptable absorption, but we human-types metabolize curcumin 4 to 16 times more quickly than rats, which changes the outcome for us.
Consider the following obstacles a dose of curcumin has to face when ingested:
- Ordinary curcumin isn't soluble in the acidic pH of the stomach. When it reaches the neutral or alkaline environment of the large intestine, much of it is made water-soluble and converted into inactive waste by glucuronidation, which is how the body rids itself of most pollutants and drugs.
- Some of the raw curcumin makes it through the large intestine intact, but then it's subjected to further metabolism by the colon's bacteria.
- A small amount eventually gets absorbed into the bloodstream, but much of it gets metabolized by liver cells and unceremoniously excreted through bile.
All of this means you can take as many as six or more capsules of ordinary curcumin and you wouldn't be able to find even a trace of its free form circulating in the bloodstream an hour later.
Thankfully, UCLA scientists figured out a solution that protects curcumin and delivers optimal free-from amounts into the body.
Solid Lipid Curcumin Particles
Biotest previously increased bioavailability by combining super-pure curcumin with the glucuronidation inhibitor piperine. The curcumin/piperine formula increased absorption by roughly 20 times that of raw curcumin and was, in its time, the best science could do.
But there's been a big breakthrough. UCLA neuroscientists discovered how to make what they call "solid lipid curcumin particles."
In simplest terms, the process consists of gently coating curcumin with lipids (DHA, lecithin, and stearic acid) to form a micelle soup, which is then dried into a free-form powder. To conceptualize this, just think of a ball of curcumin molecules entirely surrounded by protective lipid molecules, kind of like a microscopic blackberry, only rounder and golden-colored.
These curcumin micelles survive the acidic pH of the stomach. They laugh in the face of glucuronidation and scoot into the small intestine long before the colon's bacteria even wake up for breakfast.
The end result is a 95-times increase in free-curcumin blood concentration, along with a much longer activity. You can take a single 400-mg capsule and rest easy because it keeps working for 24 hours.
And none of this is theoretical. Solid lipid curcumin particles were thoroughly tested in humans. The results were compiled, analyzed, written up, and submitted for peer review, culminating in a patent.Biotest incorporated these solid lipid curcumin particles into its new Micellar Curcumin™ formula.
What Does It Do?
Curcumin helps increase HDL, decrease total cholesterol and triglycerides, and promotes healthy arteries. Curcumin even improves muscle recovery, suppresses normal workout-induced inflammation, increases exercise performance, and even potentially raises testosterone levels by acting as an anti-aromatase.
And keep in mind that all of these findings are attributed to regular curcumin. But if you want to FULLY tap into curcumin's wide range of real benefits, whether they're health-related or sports and joint-health related, Biotest's Micellar Curcumin™ supplement is the inarguable choice.
The patented curcumin material has over 50 human, pre-clinical, and review papers in publication to support its efficacy, many of which are referenced and synopsized below.

Further evidence of benefits to mood and working memory from lipidated curcumin [solid lipid curcumin particles] in healthy older people: A 12-week, double-blind, placebo-controlled, partial replication study. Nutrients. 2020 Jun 04. 12(6): 1678. DOI: 10.3390/nu12061678. ABSTRACT: A partial replication study by researchers at Swinburne University reveals [lipidated curcumin] improves aspects of mood, memory, and working memory in a healthy older cohort. The pattern of results is consistent with improvements in hippocampal function and may hold promise for alleviating cognitive decline in some populations. This study examined a similar population with slightly elevated cognitive abilities, while eliciting similar results to the first clinical published in 2014 - see Cox KH et al, 2014.

ABSTRACT: [Solid lipid curcumin particles] administered at a dose of 2000mg/day (n=16), or placebo (n=13) for 12 weeks increased brachial artery flow-mediation dilation (FMDba) by 34% and forearm blood flow in response to incremental brachial artery infusions of acetylcholine (FBFach) by 44% in middle-aged and older (MA/O) adults (45-74 yrs). Findings support supplementation with [solid lipid curcumin particles] improves endothelial-dependent dilation (EDD) in MA/O adults mediated, in part, by an increase in nitric oxide bioavailability.
