Welch's Purple Grape Nootropic

[muscleupcrohn]

Here’s a cheap, easy, and readily available cognitive enhancer for you:

The Noot: 230ml (~8oz) of Welch’s Purple Grape Juice

note: there was also a placebo group that used Welch’s White Grape Juice (which has much, much less anthocyanin content) instead of the Purple Grape Juice

Subjects: Healthy Young Adults

Results:

Purple grape juice significantly improved reaction time on a composite attention measure (p = 0.047) and increased calm ratings (p = 0.046) when compared to placebo. Order effects also indicated an enduring positive effect on pre-dose memory reaction time (p = 0.018) and post-dose calm ratings (p = 0.019) when purple grape was consumed first.

Conclusion:

These findings in a small sample of healthy young adults suggest that purple grape juice can acutely enhance aspects of cognition and mood. No significant effects of juice were observed on memory measures, suggesting that these may be less susceptible to manipulation following acute supplementation in healthy young adults. Potential mechanisms underlying these effects include modulation of cerebral blood flow, glucoregulation and inhibition of monoamine oxidase activity, all of which require further exploration.

It’s literally just Welch’s purple Concord grape juice, the stuff you can find in your local grocery store.

Good find! After learning about the cardiovascular benefits of anthocyanins, I recently added blueberries into my diet, too.

But I want to spend $40 on a stylish tub filled with powder!

Thanks. Yeah, blueberries are definitely very healthy too. A bit more expensive than grapes though, so it’s nice to see grapes have benefits too, and even a little nicer to see that cheap grape juice can too.

I’m sure you can find some fancy grape juice at Whole Foods for close to that.

Also some interesting research on orange juice:

The juice:

The 240-ml FR drink consisted of Tropicana Pure Premium Orange Juice with 5.5 g of added orange pomace fiber (240 ml) which contained a total of 272 mg flavonoids

Results:

Change from baseline analysis revealed that performance on tests of executive function and psychomotor speed was significantly better following the FR drink compared to the placebo. The effects of objective cognitive function were supported by significant benefits for subjective alertness following the FR drink relative to the placebo.

Conclusion:

These data demonstrate that consumption of FR orange juice can acutely enhance objective and subjective cognition over the course of 6 h in healthy middle-aged adults.

And a combination of orange and grapefruit juice:

The Juice:

[quote]The 500-ml HF drink was a commercially available 100 % juice (Tropicana Ruby Breakfast Juice; PepsiCo Inc.), which naturally contained 70.5-mg flavonoids

Ingredients:Orange Juice (81%), Pink Grapefruit Juice (9%), Blood Orange Juice (9%), Elderberry Juice[/quote]

Results:

The HF drink was associated with significantly increased regional perfusion in the inferior and middle right frontal gyrus at 2 h relative to baseline and the control drink. In addition, the HF drink was associated with significantly improved performance on the Digit Symbol Substitution Test at 2 h relative to baseline and the control drink, but no effects were observed on any other behavioural cognitive tests. These results demonstrate that consumption of flavanone-rich citrus juice in quantities commonly consumed can acutely enhance blood flow to the brain in healthy, young adults. However, further studies are required to establish a direct causal link between increased CBF and enhanced behavioural outcomes following citrus juice ingestion.
