Blueberries: So Many Darn Anthocyanins and So Powerful

As James Joseph PhD, past Chief Neuroscientist at Tufts University and past head of the USDA Anti-Aging Center at Tufts, said, It’s not that the individual anthocyanins in blueberries are stronger than those in others fruits.  It’s that blueberries have so darn many types and in such large concentrations. In ORAC tests by the USDA wild blueberries had the highest score of any fruit in North America.

Yes, Blueberry Extract has many darn anthocyanins and is so powerful.

The awesome antioxidant power of blueberries comes from two main sources.  One is chlorogenic acid which is among the cancer fighters in tomatoes and bell peppers. Chlorogenic acid is found in large quantities in blueberries.  And the other is in the anthocyanins. (Wilhemina Kalt, cited in The Color Code by Joseph)

Consuming a cup of blueberries a day or taking a capsule of the Blueberry Extract  makes you think better. 

The Blueberry Extract's color is so blue that it is almost purple.  It provides much antioxidant, anti-inflammatory, neuro-regenerative punch as documented over the years by our doctors with their patients.  A side note:  I hear quite frequently from our clients that they have tried the product on their animals with amazing results.  After all it was, in part, the therapeutic success in animal research that made the case for possible successful outcomes for us humans.

Blueberries have a unique polyphenol profile and are an excellent source of various anthocyanins and other phenolic compounds such as proanthocyanidins, phenolic acids, and flavonoids.

Rutledge, G. A. et al, 2021, correlated 1 cup a day of blueberries or daily supplementation with blueberry powder with improved cognition after a consistent consumption of 90 days. 

Rutledge et al. wanted to know if taking blueberries actually shows changes in the concentrations of anthocyanins and phenolic acid metabolites. They found that blueberries significantly altered plasma concentrations of circulating anthocyanin and polyphenol (phenolic acid) concentrations in subjects consuming blueberry compared to the control group.

The study also demonstrated that blueberry metabolites peak at different times during a 24 h period post-consumption and some metabolites exhibit biphasic patterns.  Furthermore, a consistent daily consumption of blueberry leads to the retention and persistence of some phenolic acid compounds over a longer period than is observed in acute studies.

Plasma phenolic acid and anthocyanin concentrations were significantly altered after 90 days of BB consumption compared to the control, and concentrations of these plasma phenolics correlated with improvements in cognition.

The BioImmersion Blueberry Extract is a powerful product, with concentrated phenolics from the whole fruit which is responsible for the therapeutic benefits.  Each capsule contains 500mg of this precious extract, equivalent to one and a quarter cups of blueberries.  In fact,  it takes 80 lbs. of blueberries to get 1 lb. of this extract!

Recommended dose:  1-2 capsules daily.
