Anhidrosis Treatment - Success Story

Howdy thought I’d share a success story. Got a horse on lease from Toronto area. And somewhere around end of May beginning of June realize he is not producing enough sweat. Have a lot of tests run, ever;ything normal except low vit e. Start him on elevate, an Omega 3 supplement, One AC, and and electrolyte with sodium chloride as first ingredient. Give it a month. Zero change.

Try the patches, Nothing (but they gave money right back at least).

Try Accupuncture, see slight increase, now sweating more under tack but nothing anywhere else.

Handle this by only working under 85, and have a spray bottle of alcohol and water mix, so I can spray him down whilst riding, also soak him before I get on and as soon as I get off.

Last week of august, trainer is like vet says he’s really ahd good luck with 03 Mega Sweat. And I’d looked at it before but I was already giving the horse, Omega 3s, E etc., seemed like a waste but at this time I’m kinda desperate. I was coming to the end of my lease and I need to decide if I can live with this. So I go what they heck. The website says, you’d see improvement within 72 hours if it was going to work.

Well 24 hours after first dose (and it’s a massive dose don’t get me wrong) he starts sweating between his front legs. By 72 hours he was a normally sweating horse. Obviously your mileage my vary but it was pretty freaking incredible.

You only do 1 gallon of the Mega Sweat then are supposed to switch to their complete. I’m going to do that, and keep him on it through a year and see how it goes, hopefully next year we won’t even need the Mega Sweat.

Now it is a liquid, which is a huge pain in the butt, not as big of a pain as having a horse that doesn’t sweat.


I have seen it in my research as well and that company sure does make strong claims! It’s clear they really believe in their product. Thank you for sharing. The OneAC is working for me so far, but I will definitely keep that one in the back of my mind.

Thank you for sharing your experience!

Thanks for sharing, and I’m glad to hear that your horse has improved. I saw the link posted elsewhere, and am waiting for a delivery today. It will be a very large dose for my small horse who gets tiny meals, but he ate KER EO3 without a problem (much, much smaller dose, however), and it’s only for two weeks.

The theory behind MegaSweat is entirely different, so I thought I might as well try it, as I’ve done everything else. My horse has already been sweating much, much better with previous changes in anhidrosis supplements (and drinking more, too).

I requested the offered complimentary analysis comparison between their Omega 3 oil and the KER product (with which I was very happy), and their nutritionist is getting back to me on that. One advantage of the 03 products is that it is stated that they don’t need to be kept in temperature controlled conditions – I quit feeding the KER oil during this extremely hot summer, because of concerns about possible rancidity if kept in the barn during this weather, and planned to return to it as soon as it cools down. True Sweat and Platinum Refresh that I’ve also tried must both be kept cooler than our barn allows in this heat, which is an inconvenience, as we have had to carry doses over twice daily.

Luckily my barn has access to a fridge in the feed room for any supplements that need it. But it is nice that this one really doesn’t.

I’ve thought of having a mini fridge in my tack room, but that unfortunately wouldn’t really help here with items that must be kept between 40 and 80 degrees F (True Sweat; Refresh was similar) – a fridge could easily be a little too cold (ideal temp is below 40F).

Or Bute, which is supposed to be stored at room temperature, labelled as 59 to 86F. For these, I need either decent outdoor temps, or must keep them in the house.

Yeah I think our fridge is kept a bit “warm” since it’s not for like milk… but it still might be too cold for that. good point. We’re lucky that the feed room is in the back of a bank barn so tends to stay a more steady temp.

Please share, if you can, the information you receive from their analysis of the O3 products. Im curious what would make this product superior to KER O3 and big doses of Vit E. Maybe it’s water soluble E.

I haven’t anything yet, but I’ll post when I do.

Thank you for sharing!

We are (hopefully) near the end of our hot season here, but curious to try next year.

How’s the palatability?

My gelding will eat anything so I’m not a good judge

My horse is eagerly eating it, licking his bowl clean. So far, we’re up to a couple ounces at a meal twice daily. He’s just under 800#, and his meals are quite small, consisting of alfalfa pellets and Renew Gold Senior, so this is a lot of added oil per meal, which I was concerned might be an issue.

He’s not that picky, but I wouldn’t say that he will scarf just anything down – didn’t care for the Refresh, for example. But he eats the Mega Sweat as though it’s a treat. I also purchased the suggested Oxy Cleanse accompaniment, and added that the second time I fed MS. He eats that no problem, as well.


Here’s the email I received from the O3 Animal Health nutrition consultant; I had asked specifically about feeding amounts for his weight (just under 800#), ramping the amount up or down, etc.:

Many horses struggled with sweating this year do to our weather. Anytime you are feeding an oil you should be concerned about spoilage. Especially in the record heat that most of the country has been experiencing. All oils can become less effective when exposed to oxygen and can spoil when heat is involved. Most of the time we are using them up within 60 days, so I’m not as concerned, but it is still a possibility no matter which manufacturer.

The KER EO3 is a great product and I recommend this oil for those horses that may have a soybean oil sensitivity. From what I can tell the EO3 is solely fish oil which means the amount of omega 3 fatty acids (EPA and DHA) are higher and it is fed at a lower amount. Our products contain fish oil as well, but due to palatability issues we added in soybean oil to our products. We have a balanced omega 6 to omega 3 ratio at less than 10:1 (ours runs 5.7:1). It makes it easier to top dress on feed/hay and not have to syringe it to the horse. We have found that more horses will readily eat this combination. Our products also include vitamin E as an antioxidant, whereas the EO3 is solely a fish oil product.

Since your horse only quit sweating this year I would continue until you have finished the whole gallon. I would not feed the loading dose (for his weight that would be 4 to 6 ounces per day) for more than 5 to 7 or 7-10 days (depending on sweat/breathing). Reduce to 2-3 ounces per day until the gallon is gone. I’m a firm believer in not changing up a whole lot at once, but rather one thing at a time. That way you know what is actually working. Thankfully it has been cooler in much of the country and hopefully continues that trend. My concern is that your horse may quit sweating next year. Hopefully not! Most clients will continue the Omega Complete to ward off any repeats next year. Any time you add oil it should be gradually increased over time until you get to the desired dose.

I do have clients that have ponies that don’t get fed grain besides a ration balancer and do well with our products on that small amount of grain or even dressed on a small amount of hay.
