Composition to enhance the bioavailability of curcumin
A composition for enhanced bioavailability of curcumin including purified curcuminoid and purified essential oil of turmeric. A method to prepare a composition for enhanced bioavailability of curcumin having purified curcuminoid and purified essential oil of turmeric.
1. A method of obtaining a blood curcumin concentration of about 92 ng/g in a human subject, the method comprising administering a composition for enhanced bioavailability of curcumin to the human subject, 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 1:3 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 for enhanced bioavailability of curcumin.
3. A method of 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 1:3 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 enhancing bioavailability of curcumin in the human subject of claim 3 , wherein administering the composition for enhanced bioavailability of curcumin 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 for enhanced bioavailability of curcumin.
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 for enhanced bioavailability of curcumin.
7. A method of obtaining a blood curcumin concentration of about 5 ng/g in a human subject, the method comprising administering a composition for enhanced bioavailability of curcumin to the human subject, 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 1:3 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 for enhanced bioavailability of curcumin.
