The pH of E3Live is around 4.5-4.7
The BrainON and BrainON Supreme come in the same range since the extract is directly from the AFA (Aphanizemonon flos-aquae) algae. The pH may seem low on the scale, but E3Live/BrainON/BrainON Supreme is detoxing and alkalizing to the body due to high chlorophyll content and other micronutrients.
This is somewhat like lemons, they are very acidic on the Ph scale but once digested and metabolized, lemon juice produces alkaline byproducts in the body and make the urine more alkaline.
