Episode 77: August Journal Club:


Dr. Ferreira starts with an overview of his research and said that he did a preliminary trial in Virginia Tech and saw that the urine pH was being decreased by using a product called polyhalite. (5:36)

Dr. Weiss pointed out that the study had a fair number of clinical hypocalcemia, about 10-15%, which is high. (27:39)

Dr. Ferreira said that in testing the polyhalite, he included between 400-500 grams per cup per day. And everything was going well in the case of Calcium Chloride; it is stronger, so you can add less and have the same acidification process. (37:03)

Dr. Ferreira wrapped up by encouraging people doing research not to get stuck in a theory. Sometimes you need to get out of the box and try different things. (48:45)
