“Hello, can you tell me how many grams are in Horse Guard? It only gives mg. I want to make sure my horses are getting enough magnesium.”
Answer by Ph.D. Equine Nutritionist, Kelsey Johnson Nonella:
Your horse is getting 0.175 grams of magnesium is his 2 ounce dose of Horse Guard. The average horse needs to consume 10 grams of magnesium a day. Magnesium is a macro mineral and therefore is consumed in amounts higher than can be provided in a 2 ounce dose. Feeds that are high in magnesium are alfalfa and flaxseed. I would recommend getting your hay analyzed in order to determine your horse’s daily consumption of magnesium. Also, keep in mind that it is very important that your horse’s calcium consumption is about twice that of his magnesium consumption.
