Leading Curcumin Brand Increases Inflammation 7x


Curcumin is one of the most popular supplements. In fact, a 2020 survey of almost 10,000 people showed curcumin as the seventh most popular supplement behind D3, magnesium, fish oil, CoQ10, multivitamins, and probiotics. 

If you’ve read our blogs for a while, you’ll know that we like curcumin. And you’ll also know that we like it because curcumin is the best natural molecule at turning off the NF-kB pro-inflammatory pathway. If your NF-kB is turned on and high, then you can experience those aches and pains in your joints. This is why this pathway is the target and “holy grail” for so many pharmaceutical companies. 

So, taking curcumin should help your joint pain, right? Well, it’s not that easy. Curcumin is lipid soluble.  This means that less than 0.5% of what you swallow gets through your gut barrier with even less getting past your liver and into your blood stream. In fact, it takes 9 grams of curcumin to be able to see amounts in the nanograms in your blood (1 milligram = 1 million nanograms). 

Given this, many companies have worked on making curcumin more bioavailable, or available to your cells. A study in 2018 from a researcher out of the University of Rhode Island compared 11 bioavailable curcumin formulations. We recently compared the best brand reported in this study to CurcElite.

First morning void is collected, and 1.8 grams of curcumin are taken. Four hours later, the second void is collected. Urines were spun and fluorescence measured exciting at 430 nm and emitting at 530 nm. The fluorescence of first void is subtracted from the second void and displayed on the graph. 

In Figure 1, you see that CurcElite has higher curcumin in the urine than the leading brand. The amount of curcumin in the urine to get the fluorescence is approximately 1.6 micrograms per mL for the baseline, 14 micrograms per mL for the CurcElite, and 0.96 micrograms per mL for the leading brand.

The issue is that the amount of curcumin in the urine of the leading brand is not above the background “noise” fluorescence, so it is difficult to say how many times more bioavailable CurcElite is than the leading brand. But it’s at least 14 times more bioavailable which translates into 14 micrograms of curcumin per mL of urine.

But what about functionality?  Did the inflammatory markers drop? Yes and no. We measure IL-6, which is closely related to NF-kB using the ELISA method. The leading brand increase pro-inflammatory markers by about 7 times, while CurcElite dropped inflammation by 30% over 12 hours. 

So, the massive increase in IL-6 is surprising. This amount of inflammation is what you would see from someone who is very, very sick. One potential reason why this occurs stems from how the leading band gets curcumin through the gut barrier. It uses a detergent called Polysorbate 80 or Tween 80.  Polysorbate 80 is a synthetic solvent used as an emulsifier in foods such as conventional ice cream that makes it smoother and allows it to hold its shape as the ice cream melts. This detergent could agitate the gut barrier, similar to how piperine found in black pepper is used to make curcumin more bioavailable.

Regardless of the mechanism, the “leading brand” in terms of bioavailability acts in the opposite direction of how we want our inflammatory markers to go. A 30% drop in inflammation from CurcElite, on the other hand, is a large enough drop so that you can feel the difference.

We purposely left out the name of the “leading brand,” so they don’t sue us. If you want to know what the leading brand’s name is, click on the study link above that will take you to PubMed. 

We recently found this paper which identifies the mechanism of why Tween 80 is so bad for you, and why it makes the curcumin bioavailable. It essentially strips of the LPS (lipopolysaccharide) from the gut bacteria. 

LPS is also known as endotoxin which is toxic. So, while LPS is a good and necessary thing for the bacteria they’re found on, they can be harmful to us humans, though they can stimulate an immune response.

So, the Tween 80 stripping the LPS off the gut bacteria is the cause of the massive inflammation we saw on participants.
