Efficacy
Statistical methods / analysis
Associations between variables will be analysed using appropriate statistical methods. Normality tests will be performed for all continuous variables. If the normality of the variables are confirmed the repeated measures ANOVA and one-way ANOVA will be used to test the equality of the means for each selected category. If the variables are not normally distributed, and cannot be transformed, then the nonparametric equivalent will be used. The statistical significance level will be set at 5% (p<0.05). Statistical analyses will be performed using SPSS 24.0 for Windows.

Summary
Brief summary
Curcumin is a well-evidenced and widely administered supplemental compound. Previous studies have demonstrated its capacity to reduce inflammation and associated physical manifestations. A large body of evidence has also confirmed that ingestion can attenuate oxidative damage.

However, the bioavailability of naturally occurring curcumin is poor. Fortunately a novel curcumin formulation, using LipiSperse® technology, has been developed which increases plasma curcuminoids concentration three times compared to raw curcumin. While the safety of this novel formulation has been demonstrated (TGA listed) its effectiveness to reduce markers of inflammation and oxidative damage is not yet known. Therefore the objective of this double blind, placebo controlled trial is to investigate, in healthy humans, the efficacy of the novel curcumin formulation (with LipiSperse® technology) to reduce markers of inflammation and oxidative stress compared to both natural curcumin (without LipiSperse® technology) and a placebo control.
