Has anyone improved their alkilinity levels using kombucha?

Don’t waste your time or money with that kind of nonsense!

Meditation is the best way to lower your acidity levels.

Never heard of this concept.
Your body prefers to be acidic, not alkaline.
Why would you think alkalinity is desirable.

Actually, your body regulates itself to generate a blood pH of 7.4, which is slightly alkaline. Two ways the body maintains this is by regulating the amount of carbon dioxide you breath out, and the amount of sodium bicarbonate excreted in the urine. There is almost no way drinking a tea will have any effect on your blood pH level, as the body’s compensatory mechanisms are too effective. So, as damien said, its bullshit.
