# Dosing & Timing
### The core issue
Dosing only makes sense when tied to formulation.
Standard curcumin powder has poor bioavailability. Enhanced-delivery formulations can achieve meaningfully different exposure at much lower nominal doses.
### General dosing logic
#### Prevention or maintenance contexts
* Standard oral curcumin often falls in the lower gram or sub-gram daily range
* Enhanced formulations usually require much lower nominal dosing than standard powder
#### Active oncology contexts
* Clinical studies have used multi-gram doses of standard oral curcumin
* Enhanced formulations may achieve similar or better exposure with lower doses
* Exact dose matching between formulations is not straightforward
### Timing principles
* Stay consistent over time
* Take standard forms with fat or with a formulation designed to improve absorption
* Split dosing may make sense because free curcumin has a short plasma half-life
* Review timing carefully around chemotherapy, targeted therapy, or radiation
### Selected study doses mentioned in the literature
* Colorectal studies: around 4 g/day oral curcumin in some trials
* Pancreatic cancer Phase II work: 8 g/day oral curcumin
* MGUS or smouldering myeloma protocols: 4 g/day with piperine in some published work
### Practical takeaway
There is no universal curcumin dose for cancer. The right discussion is not just `How much?` It is `Which formulation, in which setting, for which goal, and alongside what other treatment?`
