The Benefits of Baking Soda


I’ve never had my OTTB scoped for ulcers, but given his history and current living situation, I’m fairly confident his stomach bothers him. My friend recommended adding baking soda to his program to help. I’m confused because I’ve also heard that baking soda is used for loose stool and in some cases, it’s fed to help with lactic acid build up in muscles. Is baking soda something I should consider adding given his situation or is there a better solution? – Kristen L. from Barrington, IL

Dear KL,
You’re absolutely right, there is a lot of (mis)information out there about our friend and household staple baking soda, so let’s put some of the myths to rest so we can provide safe and effective support to our horses where they need it most.

Baking soda is sodium bicarbonate, affectionately known in some circles just as “bicarb.” It’s commonly used around the house to bake cookies, freshen laundry, whiten teeth, and perform a host of other tasks. In the stable, it has also been used for years for some honest purposes and some not-so-honest purposes. For example, some people feed it to “sweeten” the stomach at mealtime, using bicarb’s ability to neutralize acid in an attempt to help them avoid gastric distress. It does probably raise stomach pH and make the horse temporarily more comfortable, but since the effect is short-lived, there is still the need for longer-acting medications like omeprazole to treat and prevent ulcers.

Unfortunately, some trainers have given large doses of bicarb to racehorses just prior to a race in an effort to enhance performance by “pre-loading” the animal with an alkalinizing agent to buffer the lactic acid that will be produced during racing. It does lower blood pH, but it also puts the horse in harm’s way and is now prohibited on race day at all U.S. racing jurisdictions. Blood tests are performed within one hour of the finish of a race to make sure the horse’s total carbon dioxide or tCO2 levels are not too high, indicating the practice of “milkshaking.”

Researchers have experimented with a wide variety of hays, grains, and supplements, trying to cause a shift in the horse’s tCO2 levels but so far they have been unsuccessful. What this means is that it is difficult if not impossible to feed a horse enough bicarb to affect lactic acid levels in muscles or for that matter, the pH in the hindgut. Fortunately, for those horses at-risk for hindgut acidosis because of a high-grain diet or sugar-rich pastures, one company has developed a protected sodium bicarbonate. This supplement is able to make it past the acidic environment of the stomach and small intestine to the large intestine, where it delivers bicarb to the hindgut and neutralizes excess acid without creating a dangerous rise in tCO2 levels.

My advice is to work with your veterinarian to select targeted supplements and/or medications with sound science behind them to support your horse’s specific issues. In your case, supplements, over-the-counter agents and prescription medications might all be needed to make sure your horse enjoys a healthy stomach.

    What is the supplement that you referenced

    I was told to give horses 1 tsp of bicarb for 7 days to flush out the kidneys as my water contains iron and their urine output is a thick yellow, I have tried this a couple times and it does seem to work, what do you think

    I have one horse in the barn I manage with ulcers and his owner wanted me to try baking soda before we went the expensive route. I gave it to him twice and he developed a raging case of diarrhea. After that, he was treated properly with ulcer medications and now he’s a much happier camper!

    Hi, my horse has a sarquoid. He’s had chemo for a year and it’s still there. i noticed a new red and inflamed area this morning. Will baking soda help balance his PH levels? There is a product from New Zealand called Black Salf which is used to “draw” cancer out of any system. It’s an alternative solution but after the amount of chemo my boy has had, I’m not sure that I want to put him on another course of it right now. I was hoping the sarquiod was in remission but it’s clearly not. Please advise

    Natasha, My mare developed a sarcoid this year. I talked with my trainer and other riders and found the experience is not uncommon. Their horses were treated with Xterra (prescription). I wanted to go a gentler route so I ordered a Black Drawing Salve on ebay. I went with the Amish product because it was by far the “cleanest”. The salve is an herbal preparation used in earlier generations to treat boils, warts, drawing out slivers, etc. I applied this about twice a week; very sporatic application. Anyway, darned if that big hunkin’ sarcoid just fell off! It left a “crater” which healed over. You might talk with your vet about this. Oh, btw, the bloodroot is the herb that is in the salve. Good luck with your horse!

  6. Rhonda Brown says:

    Please let me know how this turns out. My OTTB has a sarcoid that was quite small when I bought him last fall but since has only grown. I’m having the vet out in a little over a week to either remove or inject it with chemo while it is still small. Thank you Elizabeth for posting about the Black Drawing Salve. Its nice to draw off the experience of a horse community.

    My horse has had diarrhea since I got him a couple of years ago. We found that putting powdered electrolytes helped. Our Tractor supply no longer carries it. A man with goats sailed give him baking soda. I am willing to try this inexpensive way, but I need to know how much per day and if anyone has had luck curing a horse using this method.
