Baking Soda As Preventive

Posted by D (Michigan) on 12/28/2007

Hello I read your recent article on using baking soda to prevent formation of CaOxalate stones. Please specifics on how oxalate kidney stone sufferers should use this supplement as part of their strategy to prevent stone formation. Are what you saying is that a low acid producing diet is more important than lox oxalate diet for oxalate stone formers?

Dear D: What I am saying is simply it is best to be cautious practice moderation of not eating too much oxalates and alkalize.

I can give you a simple demonstration of the above opinion to see how a simple baking soda will prevent calcium oxalate stones. As you know, most urine samples are already high in calcium, but it takes a form of a water soluble calcium, which can be calcium chloride, calcium bicarbonate, and other compounds.

If I prepare a small cup of urine sample, and I added a simple oxalic acid let's just say a small amount. For example, a 100 cc urine sample, and I put in only about 100 mg gram (about less than 1/16 of a teaspoon) into this, wait 5 minutes, the urine suddenly becomes cloudy (assuming of course this IS A HEALTHY URINE, if not it WOULD be cloudy). The urine will suddenly have calcium oxalate stones, and precipitate down into the cup samples. The precipitate is calcium oxalate.

If on the other hand, you add say 1/2 teaspoon of baking soda (for demonstration purposes!) into a 100 cc sample of urine. Stir and allow the baking soda to dissolve. Then add the same amount of oxalate into the urine. The calcium oxalate wouldn't form and the urine well be mostly clear solution. The reason is the sodium bicarbonate reacts with the oxalic acid to form sodium oxalate and it is now less reactive to form a calcium oxalate. Thus the urine, or the kidneys with SUFFICIENT levels of bicarbonate would allow a safe excretion of oxalates WITHOUT the stones. Of course, if you PUT TOO MUCH oxalic acid in this soltuion, it will overpower all the alkalinity of the baking soda and form the calcium oxalate, by the virtue of too much acidity of the oxalic acid. Hence, the lesson to be learn is not to take too much oxalic acid AND proper alkalinity. There is no getting around this fact as to who wins the horse race.

Let's look at the human intestines, it works in a similar manner, but with a slight twist. An oxalic acid goes into the intestines, and assuming WITHOUT sufficient alkalinity to neutralize the acidic oxalic acid, it enters the blood stream and sees a calcium. The oxalic acid will be neutralized with calcium in the blood forming calcium oxalates and clogs into the kidneys. On the other hand, if the intestines has sufficient sodium bicarboante already, the oxalic acid will react with this, to form a more water soluble oxalic acid without reacting with the calcium, and if it enters the blood stream, it won't react with the calcium like in the urine sample demonstration and is safely excreted by the kidneys. So if the urine pH is kept near 7, most of these problems of kidneys stones from calcium oxalate will not likely to occur. However, it must always be assumed that we are not purposely eating too much oxalates and also practice moderation from not eating or drinking too much foods high in oxalate too. Caution should always be considered, but as the demonstration I have shown, adding baking soda did prevent forming of calcium oxalates. Mind you, this is not a perfect way to rid of oxalates, and certain other supplements are just as important, such as vitamin C, sodium citrate, potassium citrate, and vitamin B6 which also prevent formation of oxalates too. Thus the body should have at least proper alkalinity, some vitamin C without a deficiency and other things too

A 4mm was discovered by cat scan after back and groin pain. Have been trying to pass it with loads of water and Flonase. So far no result. The urologist wants to remove it surgically which is not my preference. This morning drank 3oz pure lemon juice... I need to know how to take the baking soda, what quantity mixed with how much water... How often etc... Can you please help me ? Thank you
