In some older Turmeric formulations Black Pepper was added to help with the absorption. This has largely been superseded (with exceptions) as continued use of black pepper can lead to liver damage.
Coconut or other oils have been used to also aid absorption because Turmeric/Curcumin is oil soluble. The advanced Tonik formulation does not need these additives. Tonik provides a very modern formulation that uses essential oils from within the Turmeric Root (Rhizome) which aid absorption without the need for any other additives. This means almost seven times more Curcumin gets absorbed and provides the beneficial effects and only a one capsule twice a day dose.
Have you tried Tonik No. 3 Turmeric aka. Curcumin yet?
