Turmeric with its natural content of 2 - 4% Curcuminoids (the active, healing and protective substances in Turmeric) is naturally absorbed in the body - both via the blood and the lymph - and the active substances remain in the body for a long time, up to 8 hours. The problem is that large doses are needed for the body to get help with e.g. sore joints and muscles, about 15 - 30 grams of powder per day. Something that most stomachs cannot handle.

Therefore, there is a natural need to concentrate the content of Curcumin - as many companies have done. The problem is that only a small amount of curcumin is absorbed by the body.

The low bioavailability of pure curcumin is due to the fact that the body perceives it as 'foreign'. The body therefore instinctively tries to protect itself by excreting the substance in the stool or urine. For this purpose, there is a special protein (P-glycoprotein) in the intestinal walls whose main task is to 'throw back' unidentified foreign substances.
‍

The next obstacle is the liver. Here, the remaining free curcumin is met by a number of liver enzymes (CYP3A4) whose sole task is to break down 'intruders' into water-soluble, inactive metabolites that can then be excreted in the urine. The free curcumin is here converted into inactive, water-soluble curcumin glucoronide.
‍

Therefore, only a small proportion of the original Curcumin reaches the blood and cells where it can be useful. It is this problem that Arjuna, the company behind curaMIN, has solved by creating BCM95, a complex of Curcumin and essential oils. A complex that is absorbed as naturally as Turmeric but contains 30 times more Curcumin.
