Aurorablue Wild Alaska Blueberry Proprietary Blend
Also known as: Wild Alaska Blueberry, AuroraBlue®, Vaccinium ovalifolium, Vaccinium caespitosum, Vaccinium uliginosum, Vaccinium alaskensis
Overview
AuroraBlue Wild Alaska Blueberry Proprietary Blend is a concentrated extract derived from wild blueberry species native to Alaska’s rainforests and tundra, including Vaccinium alaskensis, Vaccinium ovalifolium, Vaccinium caespitosum, and Vaccinium uliginosum. These berries thrive in harsh climatic conditions, leading to a high concentration of bioactive compounds. The blend is marketed as a botanical antioxidant supplement, rich in polyphenols. It contains high levels of anthocyanins (4-5% dry weight), proanthocyanidins (3.5-4%), and flavonols such as quercetin, myricetin, fisetin, and catechins. AuroraBlue reportedly possesses up to 10 times the bioactive compound content and antioxidant capacity compared to cultivated blueberry varieties from lower latitudes. Its primary uses include antioxidant support, potential cognitive enhancement, cardiovascular benefits, and blood sugar regulation. While the individual wild Alaska berries have been studied for their antioxidant capacity and bioactive content, direct clinical evidence specifically on the proprietary AuroraBlue blend is limited, with most supporting evidence derived from studies on wild blueberries or related Vaccinium species.
Benefits
AuroraBlue Wild Alaska Blueberry Proprietary Blend offers several potential benefits, primarily due to its high antioxidant capacity. Alaska wild blueberries have demonstrated ORAC (Oxygen Radical Absorbance Capacity) values 3-5 times higher than cultivated blueberries, indicating superior antioxidant potential. While direct studies on AuroraBlue are limited, research on wild blueberry extracts (not specifically AuroraBlue) has shown subtle but statistically significant improvements in executive function and cognitive reaction time in healthy older adults when supplemented at a 222 mg dose. This suggests potential cognitive benefits, though the effect sizes were modest. The same research also indicated acute reductions in systolic and diastolic blood pressure, suggesting cardiovascular support. Additionally, preliminary in vivo studies with bog blueberry species suggest potential for maintaining healthy blood sugar levels. Older adults may particularly benefit from the modest cognitive and cardiovascular effects. The cognitive improvements were subtle and limited to specific outcomes, and while blood pressure reductions were statistically significant, further confirmation is needed. Acute effects on cognition and blood pressure have been observed within hours post-dose in randomized controlled trials, but longer-term effects require further investigation.
How it works
The primary mechanism of action for AuroraBlue Wild Alaska Blueberry Proprietary Blend revolves around its rich content of anthocyanins, proanthocyanidins, and other flavonoids. These compounds exert potent antioxidant activity by scavenging reactive oxygen species, thereby reducing oxidative stress. They also modulate endothelial function, leading to improved vascular health, which contributes to blood pressure regulation. In the central nervous system, these bioactives may offer neuroprotective effects through anti-inflammatory pathways and by promoting vasodilation, potentially enhancing cerebral blood flow and supporting cognitive function. Anthocyanins and proanthocyanidins are known to interact with oxidative stress pathways, endothelial nitric oxide synthase (eNOS), and various inflammatory mediators. Anthocyanins from wild blueberries are bioavailable and may persist longer in circulation compared to those from cultivated varieties, contributing to their sustained effects on the cardiovascular, central nervous, and metabolic systems.
Side effects
AuroraBlue Wild Alaska Blueberry Proprietary Blend, like other wild blueberry extracts, is generally regarded as safe, with no significant adverse effects reported in clinical trials. There are no common (>5%), uncommon (1-5%), or rare (<1%) side effects documented specifically for this blend or for wild blueberry extracts in general. No well-documented drug interactions have been established. However, caution is advised for individuals on anticoagulant medications due to the potential effects of polyphenols on platelet function, although this interaction is not definitively proven for blueberry extracts. There are no established contraindications for its use. Limited data are available for special populations, but studies involving older adults have not reported any safety concerns. Overall, the safety profile appears favorable, consistent with the consumption of wild blueberries as a food source.
Dosage
The optimal dosage for AuroraBlue Wild Alaska Blueberry Proprietary Blend is not yet well-established, as direct clinical trials on the specific blend are limited. However, clinical studies on wild blueberry extracts have used doses around 222 mg to observe cognitive and cardiovascular effects. In commercial supplements, doses of AuroraBlue typically range around 50 mg per capsule. The maximum safe dose has not been determined, but wild blueberry extracts are generally well tolerated. For cognitive benefits, acute effects have been observed within hours post-dose, suggesting that timing relative to meals might influence absorption. The blend is often available in capsules containing dried berry powder, utilizing technologies like Refractance Window® drying to preserve bioactive compounds. This drying method and the presence of various flavonoids are believed to enhance bioavailability. No specific cofactors are identified as required for its efficacy.
FAQs
Are cognitive benefits proven?
Some evidence from randomized controlled trials using wild blueberry extracts shows modest cognitive improvements in older adults. However, specific clinical data directly proving cognitive benefits for the AuroraBlue proprietary blend are currently lacking.
Is it safe for daily use?
Yes, based on the safety profiles of wild blueberry extracts, AuroraBlue is generally considered safe for daily use. No significant adverse effects have been reported in clinical studies of similar extracts.
How soon do effects appear?
Some acute effects, particularly on cognition and blood pressure, have been observed within hours after a single dose in studies involving wild blueberry extracts. Long-term effects may require consistent use.
Does it help with blood sugar?
Preliminary in vivo data suggest potential benefits for maintaining healthy blood sugar levels, particularly from bog blueberry species. However, human clinical data specifically on AuroraBlue for blood sugar regulation are limited and more research is needed.
