The curcuminoids
Why is curcumin poorly absorbed?
We also know that turmeric, and especially its active constituent curcumin, are poorly absorbed by the body. The reason for this is that
curcumin dissolves in fat, rather than in water
, and as the digestive system is a rather watery environment, most of it just ends up being excreted by the body.
Is turmeric a polar?
It is a hydrophobic molecule with a logP value of ~3.0. It is almost insoluble in water and
readily soluble in polar solvents
like DMSO, methanol, ethanol, acetonitrile, chloroform, ethyl acetate, etc. … The molar extinction coefficient of curcumin in methanol is 55,000 dm3·mol−1·cm−1 at 425 nm.
Is curcumin water soluble?
Curcumin is an
oil-soluble pigment
, practically insoluble in water at acidic and neutral pH, and soluble in alkali.
What makes curcumin hydrophobic?
It should be emphasized that the hydrophobic association of curcumin-curcumin or curcumin-protein is
promoted by the surrounding water molecules
. The present study indeed shows that curcumin monomers form clusters through the association of phenyl rings17, 18.
Is curcumin the same as turmeric?

To date, the curcumin formulation comprised
of liquid droplet nano-micelles containing Gelucire
®
and polysorbate 20 (BioCurc
®
)
has been shown to have the highest bioavailability with an absorption >400-fold as compared to unformulated curcumin [15].
How do you get the most curcumin out of turmeric?
Short cooking times (under 15 minutes) do not destroy turmeric, but will in fact increase the bioavailability of curcumin. So heating turmeric in a
golden latte
or adding it to your cooking, such as in curry or scrambled eggs, will maximise its absorption by the body.
Can your body absorb turmeric?
Turmeric is fat soluble – meaning it dissolves in fats. Without the fats binding it, the turmeric struggles to make it through the
liver
and stomach without being absorbed prematurely, and into the small intestines where it can be transferred through to the blood.
Does turmeric powder dissolve in water?
Answer: Turmeric is a plant, and therefore is made up of many different chemicals. Most of the aromatic compounds in turmeric are either water-soluble or disperse well in water, and are too small to be strained out. … You are not the only person to experience this, and
there is no such thing as soluble turmeric
.
