Dr O,
In prevention of urological problems, is there any difference between ascorbic acid v calcium ascorbate being added to the feed? I notice the research indicates ascorbic acid. |

Hmmm I am uncertain about the pharmacology of calcium ascorbate Sally in horses but in humans calcium ascorbate is a acceptable form of vitamin C and I know of no reasons this would not also be true in horses.
As a solid any form of ascorbic acid, also known as ascorbate, is in the form of a salt. Often complexed with sodium, magnesium, or calcium. Of course with the mineral complexes you have to take into account the weight of the mineral and pre calcium ascorbate provides 114 mg of calcium per 1,000 mg of ascorbic acid. There is the consideration that if you are trying to prevent the formation on urinary stones that contain calcium you are increasing the amount of calcium the horse is taking in. Lastly the rationale behind using calcium ascorbate is that the calcium acts as a ph buffer and it is the ph of the urine you are trying to acidify, this might indicate that it will have less effect on the urinary ph but I find no work to support or deny this.
