Study/development note Experiments have found that high taurine has the effect of slowing down memory decline and cognitive decline. Due to its low molecular weight, high taurine can pass through the blood-brain barrier, thereby reducing the toxicity of β - amyloid protein. In clinical trials, researchers found that high taurine preserved about 68% more brain volume than the control group, preventing memory decline and cognitive ability caused by amyloid protein.
