You mentioned being interested in a product called Theracumin and wanted to know if I have tried it. The short answer is I have not tried it. Here's some information I found this morning – " Theracurmin is formulated using proprietary manufacturing methods to increase curcumin's solubility and bioavailability in the body. To create Theracurmin, curcumin is mixed with gum ghatti along with other ingredients and ground down using a wet grinding mill to reduce its particle size." — The Difference Between Curcumin & Theracurmin: https://womensvoice.com/en-us/articles/nutrition/the-difference-between-curcumin-theracurmin/
Here are a couple of research articles from NIH. The second one contains a table -Curcumin Formulation Strategies to Enhance Absorption that shows some top rated products including Theracurmin and the one I am currently taking Meriva.
