How many mg of selenium is an overdose?

What is the RDA for selenium in horses?

I have been reading a ton about selenium and horses, and trying to find the RDA for horses.

I'm not looking for a supplement, but I do want to be sure I'm not doing harm to my horse by giving him a supplement. (I understand it's hard to give a horse a supplement, but if I can find some sort of info, it would be helpful.)

I will admit I've tried a lot of supplements and nothing has worked. (I understand it's hard to give a horse a supplement, but if I can find some sort of info, it would be helpful.

Thanks! It's selenium alone. However, most of the selenium out there in dietary supplements is selenomethionine. Some, not all of this is bioavailable. There are some claims made for molybdenum and selenium as well. I would encourage you to do some research on this stuff, there are plenty of claims out there.

The RDA is for humans - but I would assume that it would be the same as for horses. There are some horses out there who need to be supplemented with inorganic selenium, some need it in organic form. Check out the equine supplement thread.

My opinion: If your horse needs any type of supplement, give it to him. Be sure to keep an eye on him to make sure he's not toxic or anything, but I don't see anything that a supplement would hurt the horse.

I think it depends on the supplement you use.

How much selenium is too much for horses?

I know this is the wrong place to ask this question but here it goes.

I have a 30 month old gelding that I bought from a riding school in Colorado. He had a bad injury on his off leg and was having issues with his front end. He has been riding on my trailer since day one but I wanted him to get back on his feet. I got him up and running but he seems to be struggling with his right front. He is not stiff or sore, he just looks like he is holding it. I know that it is not good to have a horse with a sore foot but I am going to start him on some selenium and see what happens.

I am looking for some insight. I know that when a horse is going through the muck stage of joint repair that selenium is a common practice. Any other ideas on how to get him back on his feet?
Selenium is more about arthritis. It works on all kinds of arthritis, but especially the more severe kinds. Selenium works to reduce the inflammation that leads to the formation of calcium deposits that block joints, and eventually causes arthritis. Selenium is good to use for horses that have joint problems, especially if they have a history of joint problems.

Some people have had success with taking the supplement for horses, but most people find it doesn't do much for the horse, and it may even make the problem worse. The horses are supposed to take it for a few months, and then they should be off it. If it helps, it is great. If it doesn't help, it is worthless.

How much selenium is too much? Selenium is supposed to be used for horses that have joint problems, but it doesn't seem to do much for the horse. It can cause a variety of problems, such as a decreased appetite, hair loss, a decrease in muscle mass, weight loss, and it can even kill horses.

How many mg of selenium is an overdose?

I need to know for us humans.

I'm not talking about overdoing a supplement.

And I don't mean that the amount of Se should be lower for women than men, although that does make sense. But for the average person, on average, how many mg of selenium is considered an overdose.

The answer of course depends on if we are looking at the total amount in your body, or just selenium in your diet. The first one is what you'd want to know, and would be the answer you seek. The second is what you'd want to know, and would give you some guidelines on what you should be eating.

I'd have to agree with the other two posters that while it is good to get a good balance of Se, a little bit isn't going to hurt you in most cases. I think if you only get enough to maintain the level in your system you should be okay. Selenium is pretty good at being used by your body and not getting stored in places where it is an issue (eg liver or muscle tissue). Selenium is pretty good at being used by your body and not getting stored in places where it is an issue (eg liver or muscle tissue).

Selenium is stored in the skin and muscle cells. That's why the supplement doses are different depending on the part of the body you're taking it for.

But the liver can store Se, and I've seen too much damage caused by overdosing on supplements that I just don't see it being necessary for many. You probably already consume enough via your diet and not drinking water, and I'm sure you're already well seleniumed.

In my personal case I am very sensitive to metals. I have had terrible reactions to taking magnesium which I eat often. I have had bad reactions from supplementing with iron. I get headaches when I try to get my levels up by supplementing with zinc.

So, no. Do not take any more selenium than you need.
