Comparison of turmeric supplements based on bio-availability

Based on published studies or manufacturer claims on manufacturer websites (complied on March 15, 2017), of all known turmeric supplements only 3 supplements deliver curcumin levels in blood of more than 100ng/ml per 100mg active components on the basis of C-max values per 100mg of actiive components.
These are Thercumin™, Curcuma Hydrogel® Pastilles and NovaSOL®.
Table with comparison of bio-availability of different turmeric supplements. How much curcumin do they deliver in the blood? Which curcuma products are most favourable? Curcuma Hydrogel pastilles deliver relatively high doses of active components in the blood for a relatively low price!
Theracurmin™ Sunagawa Y, et al, Curcuma Hydrogel® Gelnova study, NovaSOL® Schiborr C, et al.
The curcumin levels in blood for CureSupport Liposomal Curcumin C3 complex® are not known,
Supplements that deliver less than 100ng/ml in blood per 100mg active components are among others
BCM-95® e.g. LifeExtension® Super Bio-Curcumin®
Longvida® e.g. Vitals Curcumine SLCP™
Meriva® e.g. Now® Curcumin Phytosome
Sabinsa Curcumin C3 Complex® (with BioPerine®) e.g. VitamineMan
UltraSOL® e.g. Lamberts® Curcumin Ultra.

One may not conclude that these products do not work or are less effective.
This is purely a comparison on bio-availability.
The above comparison has been compiled with due care.
The reference product used per manufacturer/study can vary in quality, so a claim of "xx times better than reference product" is relative. Protocols are also varied.
The curcumin levels delivered in blood (nanograms per milliliter) is an appropriate bio-availability parameter to compare various supplements.
