I’m with walkinthewalk on products from HorseTech.com. My gelding was on Selen, which is natural vit E and selenium for several years. Selenium levels in the soil around there are very low When I added Sentinel Performance LS to his diet I didn’t pay any attention to total selenium. His bloodwork came back and he was right at the top of the range.
I called Rod, the owner, at HorseTech. I also use their biotin and HylaSport CTS for his joints. (I also love the leather soap.) He looked up an online map of selenium levels in the soil. Low in Maine? Depends. He said in the Bangor area it’s close to normal, but down here it is low. He looked up the grain on the Blue Seal site. He converted them to the same unit of measurement and said the grain has enough selenium. I had just opened a new container of Selen. He suggested a smaller serving of both products, not mixing them. A couple of days later a few pounds of the natural E arrived, at no charge. With my cookies, of course!
I saw a comment in an article recently about buying products from different manufacturers. We don’t think about this often enough. - trying to get the best combination of nutrients. It is common to have too much of something in product A, and not enough of something else in product B, while trying to solve the issue with nutrient number 3 in product C. .
I prefer to do business with smaller companies, particularly family-run operations like HorseTech… Rod, the owner, knows his stuff, as they say, and he is always available to answer questions. He has been very helpful as my 26 y.o. gelding continues to get older. He will do custom products: He figures out the formula and assigns it a product number so it is easy to reorder. He usually sends a sample for a taste test. Their service is terrific, free shipping, and cookies - although there was a shortage when the virus hit.
Also, the ingredients and guaranteed nutritional levels are on the bag of Sentinel LS grain, and they are on the website. It is a fixed component formula so it doesn’t vary from batch to batch. I’d be cautious if ingredients are on a tag sewn to the bag. Often it means they vary between batches trying to keep the cost down. Is the “corn” ground, flaked or cracked? Does that make a difference? JB?
