A liquid selenomethionine — selenium bound to the amino acid methionine, rather than the inorganic sodium selenite most selenium supplements use.
Why the organic form matters
Selenomethionine is actively taken up from the intestine and used by the horse during protein synthesis.
Inorganic selenium isn't. Sodium selenate has to be converted by micro-organisms in the caecum and small intestine into an organic form before it can be absorbed at all, and most of it never makes it — the majority is excreted in faeces and urine, with as little as 40% actually taken up.
That difference is the entire argument for this product. If you're supplementing selenium on New Zealand's selenium-deficient soils, the form you choose decides how much of it the horse actually gets.
Made in New Zealand by Vetpak.
Selenium has a narrow margin between adequate and toxic. Don't stack selenium sources, and if you're unsure of your horse's status, blood test before supplementing.

FAQ
All your questions, answered.
The thermoneutral zone is the temperature range where the body can maintain its core temperature with little to no extra energy expenditure. For humans, this range is quite narrow at 21–28 °C, but for horses it’s much broader at 5–25 °C.
This difference means we should avoid rugging horses based on how cold we feel. Over-rugging can lead to serious health issues, including metabolic problems and thermoregulatory dysfunction.
Tips for Choosing a Winter Rug Weight
-
Clipped horses may need a heavier gram fill to stay comfortable.
-
Remember: horses warm themselves more easily than they cool down under a rug. If unsure, choose a lighter rug.
-
Check your horse regularly to make sure they are neither too hot nor too cold.
-
Consider your horse’s age and natural ability to stay warm.
-
As a general guide, rugging is usually appropriate when temperatures drop below 5–10 °C, but always adjust for your horse’s individual needs.
-
Always ensure rugs are waterproof. A wet rug is worse than no rug at all.
This is an indicative guide only. Always take into account factors such as wind chill, your horse’s age, weight, and condition.
