Abstract

Background: Curcumin has several health benefits due to its potent antioxidant and anti-inflammatory properties,

but its bioavailability is very low, limiting its potential. We have developed a novel curcumin formulation, TS-P1, which

has an 85.2-fold higher bioavailability of curcumin than raw curcumin.

 

Objective: To investigate the efficacy of TS-P1 on fatigue, mood status, and autonomic function.

 

Methods: Ninety healthy Japanese adults were randomized to the placebo or TS-P1 group and took either the placebo

or TS-P1 containing 150 mg of curcumin for 12 weeks. Visual Analogue Scale for Fatigue (VAS-F) scores, Profile of

Mood States Questionnaire second edition (POMS2) scores, and autonomic functions were measured every 4 weeks.

 

Results: Both groups showed an improvement in the VAS-F over the study period, but there was no significant

difference between the placebo and TS-P1 groups. However, the mean change from baseline in the anger and

depression scores of the POMS2, particularly in those aged 40 and over, in the TS-P1 group showed a greater range

of decline at week 12. The mean change from baseline in LnLF and LF/HF also decreased in the TS-P1 group. Blood

pressure also decreased in the TS-P1 group.

 

Conclusions: These data suggest that TS-P1 induced a parasympathetic dominant state, and that curcumin has an

important role in the regulation of autonomic balance. 12 weeks of supplementation of TS-P1 is expected to improve

both mood status and vascular function.
