Yes, thank you. My point precisely. Many of the products people think of as being classified as “supplements” are actually not labeled as supplements. They are labeled and regulated as feeds. Feed does not mean grain or a complete ration. It is confusing for consumers and some companies as to what is a feed supplement and what is an animal health supplement.
Any product that makes a nutritional claim (supports healthy hoof growth, maintains balance in the digestive tract, formulated to support healthy skin and coat) is a feed product. Most of your skin/coat, hoof, digestive, and immune “supplements” are labeled and regulated as feeds. Also, if the base of the product is made of feed ingredients (flax, alfalfa, rice bran, etc.), than the product will also be considered and regulated as a feed. Only products that make a structure/function claim fall under a animal health supplement. Yes, joint supplements live in this category, but are not allowed to make diseases claims (treats arthritis, increases joint strength, repairs joint cartilage, etc.) as the FDA would (and does) send letters of cease and desist as the supplement would then need to be labeled as a drug. The FDA considers and regulates animal health supplements as drugs, specifically as “drugs of low regulatory priority.” Of course there are many joint products out there that make claims of “diagnosing, curing, mitigating, treating or preventing disease, or affecting the structure or function of the body other than food”, but they are flying under the radar for now.
I really encourage everyone to look at the NASC website (FAQs) to learn more about the different classifications and how both feed and animal health supplements are regulated.
As far as research into the supplements, it depends on what ingredients you are looking for information on. Ingredients like Tasco, Diamond V, YeaSacc, Zinpro 4 Plex, ASU, and many others all have a considerable body of research behind them to test for safety and efficacy. Is every supplement clinically tested before it is sold, no. Neither is the majority of food you eat or the vitamins you take. Reputable companies use active ingredients in their supplements (both feed and animal health) that have been rigorously tested and use base ingredients that have a long history of safety in horses (flax, alfalfa, rice bran). SmartPak has done some research and testing with LSU on their SmartGut and we are seeing more and more of this type of testing on supplements being presented at the AAEP conference each year.
I would always choose a supplement with branded ingredients, research associated with it, or that carried the NASC seal over ones that didn’t. No, not all supplements are created equal but I don’t see the value in lumping them all together and throwing the baby out with the bath water.
