Even selenium supplement tablets (e.g. 100 mcg of elemental selenium in whatever compound) have a distinctly 'unpleasant' smell.

I used to work next to the selenium recovery plant at Rank Xerox in Welwyn Garden City - we used to get the off whiff, and if it was bad, they usually closed the plant since that was generally a scrubber fault.

Not that there's any point whatsoever in taking them.

Sigh.

Blame it on the tarts, I say.

Why do you say that?

Because it's true?

Why do you think it is true?

Could you explain why there is no point in taking them?

Dietary Reference Intakes for selenium:

Infants

Children

Adolescents and Adults

Males age 14 and older: 55 mcg/day Females age 14 and older: 55 mcg/day

The best way to get the daily requirement of essential vitamins is to eat a balanced diet that contains a variety of foods.

You can probably get 50 ug of selenium out of chomping half a raw carrot a day, or a thumb sized bit of any meat or fish.

As long as you have enough, and you don't need much, any more is simply a waste of time.,. you will piss it straight out again.

Unless you are on a drip and cant eat solid food.

Buying in week old calves through a cattle dealer, I once had a run of partially sighted dairy/beef cross animals.

Veterinary opinion at the time was Selenium deficiency in the diet of the dams.

Kept in a bunch with fully sighted animals, they were fine, but got agitated if isolated.

Interesting. Thanks.

Did you treat the low selenium at all? Or, indeed, do you provide selenium-containing licks for all your animals?

I've been following this with interest. About 20 years ago - and I can't now recall the precise reason, but it might have been to do with a relationship between arthritic joints and selenium intake

- I started taking a selenium supplement. About three months later I was in the office doing some work on the computer, when, almost with a soundless bang, the screen leapt into sharp focus. It wasn't the screen technology that caused this, but my eyesight, which has never been good since I had measles when I was six years old. Given the time between this happening and the start of the supplementation, I didn't connect the two, until about six weeks later when I was talking to a colleague. He said that a doctor friend of his had taken selenium for eyesight problems, and his vision had suddenly snapped into focus! My colleague didn't know of my supplementation or of my improved vision.

Since those times I've come to suspect that micronutrients are the victim of their own success: having found profound beneficial effects from taking minimum doses, things have stayed there

- such as the 50mg (now 60 mg, I believe) RDA of vitamin C. Evidence suggests that animals have far higher blood levels of vitamin C than humans, for example.

Then there are the issues of poorer-quality food, failing gut absorption in older people, and the elusive but all- pervading 'balanced diet' that no-one can describe; all fascinating topics.

The three enzymes which convert thyroid hormones (Deiodinases 1, 2 and

Many people with thyroid disorders/diseases have eyesight issues. For example, enlarged pituitary pressing on the optic chiasm and thereby reducing vision. But many other ways in which it affects all steps from cornea to visual cortex. Addressing the thyroid issue can reduce the size of the pituitary and therefore stop or reduce its pressure on the chiasm.

Selenium is also interesting because it appears that the different forms (e.g. selenium yeast or the inorganic sodium selenite) have differing impacts.

It's a trace nutrient. The clue is in the name.

So you need a trace of it and might not be getting it! And, as already posted, there is evidence that it can be of specific use in certain disorders/diseases even in people getting what is otherwise regarded as an adequate intake from diet.

There's no point whatsoever in taking them.

General purpose mineral licks are available for agricultural livestock.

A complaint was fed back through the dealer and I think the following year there were only a couple of calves with problems. You could pick them out as the affected eye appeared to have a dull greenish internal reflection.

The likely cause would be housed cattle fed on a supplemented straw ration. Waste from the distillery industry is supplied to farms as a pour on appetiser. There was a move toward ammonia treated straw some years back but I don't think it caught on.

I was interested in the diagram that someone linked to - I wondered why the switches are on the earth side of the motor and not the live side. I realise it might not make a difference - but is there a reason?
