Cardiovascular benefits of bilberry and blackcurrant anthocyanins in Medox®

Medox® is a truly unique berry supplement that differs from other dietary supplements on the market.

It is a natural food supplement contains large amounts of anthocyanins from bilberries and blackcurrants that has been studied in multiple, independent, randomized double-blind placebo-controlled trials related to cardiovascular health.

Anthocyanins are plant-derived compounds (phytonutrient) that impart colours of purple, blue and red in fruits, grains and vegetables. It is a powerful antioxidant with diverse health promoting actions. Yet anthocyanins are easily degraded during manufacturing.

Sourced from wild Scandinavian bilberries and blackcurrants, Medox® is produced through a patented nitrogen extraction process that locks out oxygen to preserve and concentrate 17 naturally occurring anthocyanins.

100 % natural product origin

Medox® contains consistently high-quality wild bilberries and blackcurrants of Norwegian, Swedish and New Zealand origin. There is a big difference between bilberries and blueberries, and you can read about it here.

Scientifically proven cardiovascular health benefits

The active ingredients of Medox® have been subject to multiple, independent, human-randomized double-blind placebo-controlled trials at universities and university hospitals in subjects at risk of or diagnosed with cardiovascular problems.

The results of these studies have been published in well regarded peer-reviewed international journals, including American Journal of Clinical Nutrition and European Journal of Clinical Nutrition (see the reference list at the end of this blog).

Key clinical studies conducted using Medox® (bilberry, blackcurrant and their constituent anthocyanins) on cardiovascular health

Atherosclerosis

  • Longer supplementation (4-12 weeks) increases HDL cholesterol, reduces LDL cholesterol in dyslipidemic subjects. (1,2)
  • Anthocyanin supplementation doses of 80–320 mg/day enhances cholesterol efflux capacity (CEC) in a dose-dependant manner and improve serum HDL-C levels, see chart below. (3)
  • Anthocyanin supplementation significantly decreased serum LDL cholesterol (by 7.9%; P < 0.05), triglycerides (by 23.0%; P < 0.01), increased HDL cholesterol (by 19.4%; P < 0.05) compared with placebo after the 24-week intervention in diabetes patients. (4)
  • Longer-term supplementation (24 weeks) decreases platelet granule secretion, which lowers the chance of thrombus formation. (5, 6)

Cholesterol efflux from macrophages is the initial and rate-limiting step of reverse cholesterol transport. Cholesterol efflux capacity (CEC) is a significant indicator in the assessment of HDL-C functions. Several studies have shown a negative correlation between HDL-induced CEC and both the incidence and prevalence of cardiovascular disease (CVD). By improving HDL function, especially in improving CEC, is expected to effectively reduce CVD risk.


Cardiometabolic function

  • Anthocyanins favorably improved glycemic control and lipid profile in Chinese adults with prediabetes or early untreated diabetes. (7)
  • Anthocyanins in berries exhibited anti-atherogenicity and antiplatelet activities in a metabolic syndrome population. (8)

Endothelial function in blood vessels

  • Longer term supplementation (6-24 weeks) increases flow-mediated dilation in people with habitual low fruit and vegetable intake and hypercholesterolemic subjects. (9,10)
  • Increases blood flow due to NO-cGMP pathway, and reduces adhesion factors. (10,11)

Inflammation

  • Epidemiological evidence shows that high anthocyanin intake is inversely associated with significantly lower inflammatory score. (12)
  • Longer-term supplementation (min. 4 weeks) shows reduction in transcription factor NF-kB which lowers pro-inflammatory cytokines. (2,13)
