Composition to enhance the bioavailability of curcumin
View Patent ↗A composition having a curcuminoid and an essential oil of turmeric. A composition having a curcuminoid and an essential oil of turmeric, wherein the essential oil is present in an amount sufficient to cause an enhancement of bioavailability of curcumin when the composition is administered to a human as compared to bioavailability of curcumin obtained upon administration of a composition prepared without adding essential oil to the curcuminoid. A method to prepare a composition having a curcuminoid and an essential oil of turmeric.
1. A method for obtaining a blood curcumin concentration of about 92 ng/g in a human subject in need thereof, comprising administering to the human subject an effective amount of a composition containing a curcuminoid mixture with an added essential oil of turmeric, wherein the weight ratio of the curcuminoid mixture to the added essential oil of turmeric ranges from about 3:1 to about 99:1, wherein the curcuminoid mixture consists of curcumin, demethoxycurcumin and bisdemethoxycurcumin, and wherein the essential oil of turmeric comprises about 45% ar-turmerone.
2. The method of claim 1 , wherein the blood curcumin concentration of about 92 ng/g in the human subject is reached about 3 hours after administering the composition.
3. A method for enhancing bioavailability of curcumin in a human subject, the method comprising administering a composition for enhanced bioavailability of curcumin, wherein the composition for enhanced bioavailability of curcumin comprises a curcuminoid mixture and the essential oil of turmeric, wherein a weight ratio of the curcuminoid mixture to the added essential oil of turmeric ranges from about 3:1 to about 99:1, wherein the curcuminoid mixture consists of curcumin, demethoxycurcumin and bisdemethoxycurcumin, and wherein the essential oil of turmeric comprises about 45% ar-turmerone.
4. The method of claim 3 , wherein administering the composition results in about 5-fold to about 16-fold enhancement of curcumin concentration in the human subject as compared to administering a composition comprising the curcuminoid mixture without the added essential oil of turmeric.
5. The method of claim 3 , wherein a blood curcumin concentration of about 92 ng/g is observed at about 3 hours following administration of the composition.
6. The method of claim 3 , wherein a blood curcumin concentration of about 5 ng/g is observed at about 8 hours following administration of the composition.
7. A method for obtaining a blood curcumin concentration of about 5 ng/g in a human subject in need thereof, comprising administering to the human subject an effective amount of a composition containing a curcuminoid mixture with an added essential oil of turmeric, wherein the weight ratio of the curcuminoid mixture to the added essential oil of turmeric ranges from about 3:1 to about 99:1, wherein the curcuminoid mixture consists of curcumin, demethoxycurcumin and bisdemethoxycurcumin, and wherein the essential oil of turmeric comprises about 45% ar-turmerone.
8. The method of claim 7 , wherein the blood curcumin concentration of about 5 ng/g in the human subject is reached about 8 hours after administering the composition.
