Dietary Anthocyanins Improve Lipid Metabolism in a Dose - Dependent Manner
Study Details
Study Description
Brief Summary
In order to study the effect of anthocyanins on the improvement of glucose and lipid metabolism, randomized intervention trials were conducted to compare the effects of anthocyanins on the improvement of glucose and lipid metabolism in different dose groups.To explore the best dose of anthocyanins for the prevention and treatment of anthocyanin metabolic diseases provide an important scientific basis.

Detailed Description
In order to study the effect of anthocyanins on the improvement of glucose and lipid metabolism, randomized controlled trials were conducted to enrolled 300 patients with dyslipidemia. The subjects were divided into 0 mg / d, 40 mg / d, 80 mg / d, 320 mg/ d five dose groups, intervention for 12 weeks, comparing different doses of anthocyanins on glucose and lipid metabolism.To explore the best dose of anthocyanins for the prevention and treatment of anthocyanin metabolic diseases provide an important scientific basis.

Placebo Comparator: placebo The placebo capsules only contained pullulan and maltodextrin.During the trial period, the participants were instructed to consume 2 Medox® placebo capsules twice daily (30 min after breakfast or supper). |
Drug: Medox® Anthocyanin capsules
Subjects were orally administered Medox® capsules daily for 12 weeks.

Experimental: 40mg/d anthocyanins Medox® Anthocyanin capsules is consisted of 17 different natural purified anthocyanins.from bilberry (Vaccinium myrtillus) and black currant (Ribesnigrum). To achieve the double-blind,every group are instructed to consume the same amount of capsule. During the trial period, the participants will be instructed to consume one Medox® anthocyanin capsules and one Medox® placebo capsules 30 min after breakfast and consume two Medox® placebo capsules 30 min after supper.The anthocyanin capsules (40 mg anthocyanins per capsule) will provid a total daily intake of 40 mg anthocyanins. |

Outcome Measures
Primary Outcome Measures
- Anthocyanins dose-dependently improved blood lipids in patients with dyslipidemia. [12 weeks]
After 12 weeks intervention of anthocyanins, serum lipid profiles were measured at baseline, at 6 weeks, and at the end of 12 weeks.
Secondary Outcome Measures
- Anthocyanin supplementation improves cholesterol efflux capacity in a dose-response manner in subjects with dyslipidemia [12 weeks]
After 12 weeks intervention of anthocyanins,cholesterol efflux capacity (CEC) were measured at baseline, at 6 weeks, and at the end of 12 weeks.
- Anthocyanins supplementation improve anti-oxidative and anti-inflammation capacity in a dose-response manner in subjects with dyslipidemia. [12 weeks]
After 12 weeks intervention of anthocyanins,Urine 8-iso-prostaglandinF2α (8-iso-PGF2α), 8-hydroxy-2'-deoxyguanosine (8-OHdG) and serum malondialdehyde (MDA), superoxide dismutase (SOD), UA (urine acid), interleukin-6 (IL-6), interleukin-10(IL-10), tumor necrosis factor-α (TNF-α) and C-reactive protein (CRP) were measured at baseline, at 6 weeks and at the end of 12 weeks.
- Anthocyanins supplementation attenuate platelet hyperreactivity in a dose-response manner in subjects with dyslipidemia. [12 weeks]
After 12 weeks intervention of anthocyanins, platelet aggregation, the expression of P-selectin (CD62p) activated GPⅡbⅢa (PAC-1), platelet reactive oxygen species (ROS) and platelet mitochondrial membrane potential (TMRM) were measured at baseline, at 6 weeks and at the end of 12 weeks.
