{"product_id":"vetpak-equi-sel-selenium-supplement","title":"Vetpak Equi-Sel Selenium Supplement","description":"\u003cp\u003eA liquid selenomethionine — selenium bound to the amino acid methionine, rather than the inorganic sodium selenite most selenium supplements use.\u003c\/p\u003e\n\u003ch4\u003eWhy the organic form matters\u003c\/h4\u003e\n\u003cp\u003eSelenomethionine is actively taken up from the intestine and used by the horse during protein synthesis.\u003c\/p\u003e\n\u003cp\u003eInorganic 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.\u003c\/p\u003e\n\u003cp\u003eThat 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.\u003c\/p\u003e\n\u003cp\u003eMade in New Zealand by Vetpak.\u003c\/p\u003e\n\u003cp\u003eSelenium 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.\u003c\/p\u003e","brand":"Vetpak","offers":[{"title":"1L","offer_id":51478024192164,"sku":"EQSE1","price":35.9,"currency_code":"NZD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0009\/9103\/5451\/files\/equi_sel_558x638c0pcenter.jpg?v=1789447886","url":"https:\/\/nztack.co.nz\/products\/vetpak-equi-sel-selenium-supplement","provider":"NZ Tack Saddlery Co","version":"1.0","type":"link"}
