I just bought for Safari and immediately uninstalled because CPU usage was too heavy and didn't come down. Also, permissions are way too intrusive, why does the extension need to have access to all of my browsing history?
The original Budwig Protocol is great for the brain. It's simply quark cheese and flax seed oil. It's important to keep in mind the flax seed oil needs to as fresh as possible because it gets rancid very quickly. At best buy you own press, the seeds cost next to nothing and you'll have the best quality flax seed oil on demand. Works fantastic against acidosis.
