Blueberry Juice Benefits: Anthocyanins, Brain & Heart Research

What's in Blueberry Juice

Blueberries are rich in anthocyanins, the deep blue-purple pigments behind most blueberry research. Pure blueberry juice also provides vitamin K and some vitamin C. Pomona Organic Blueberry Juice has about 100 calories and 20g of natural sugar per bottle, with 0g added sugar.

1. Brain and Memory — Early but Interesting

A 2010 study in the Journal of Agricultural and Food Chemistry gave older adults with mild memory complaints wild blueberry juice daily for 12 weeks and reported improvements on memory tests compared with their starting scores. Studies since have looked at blueberries and attention in children and adults.

These are small studies. Research suggests blueberry anthocyanins may support cognitive function, but it's not established. Our blueberry juice for brain and memory article covers this in more depth.

2. Heart and Blood Vessels

Research on blueberries and vascular function suggests anthocyanins may support healthy blood vessel function and blood pressure. A 2019 trial in the American Journal of Clinical Nutrition found daily blueberry intake improved some vascular markers in adults with metabolic syndrome. Evidence mostly uses whole berries or powder rather than juice.

3. Antioxidant Activity

Blueberries rank among the most polyphenol-rich common fruits. Cold-pressing, rather than heat-concentrating, helps keep more of these heat-sensitive compounds in the bottle.

Why Most 'Blueberry Juice' Isn't

Many blueberry juices on the shelf are mostly apple or grape juice with a little blueberry added for color and name. Read the ingredients: pure blueberry juice lists only blueberries.

Pomona Organic Blueberry Juice is cold-pressed from USDA Organic blueberries — no apple or grape filler, never from concentrate, no added sugar — in BPA-free glass.

FAQ

• Is blueberry juice good for you? — Pure blueberry juice supplies anthocyanins and vitamin K. Research suggests potential brain and heart benefits, though most studies are small.
• Is 100% blueberry juice really pure blueberry? — Not always — '100% juice' can mean a blend. Check that the ingredient list is only blueberries.
• How much blueberry juice should I drink? — 4-8 oz a day is a typical serving. The memory study above used about 2 cups of wild blueberry juice daily, split through the day.
• Is blueberry juice as good as whole blueberries? — Juice keeps most anthocyanins but less fiber. Both are good choices.
