A BJJ tool.

It's a game changer in BJJ. You absorb the technique of the day better and your awareness and energy for the roll is consistent.

Not beneficial

[This review was collected as part of a promotion.] The Onnit Alpha BRAIN personally did not make a difference in my daily living. Despite taking it consistently, I found that there was no positive effect in my brain power. I would not recommend spending money on this product.
