My horse has been on an elevated dose of Quiessence since late May as part of a treatment protocol for headshaking. He gets 8 oz. a day, split into two 4 oz. servings. Despite this, his blood work shows that his magnesium level is consistently in the low range of normal (his blood gets tested about avery 4 weeks). For the headshaking study that he's part of, they want his magnesium level to be in the upper range of normal.
The vets at UC Davis are looking into this, but I wanted to see if any COTH-ers had any experience/insight that might be helpful. Basically, we're trying to figure out what might be interfering with the absorption of the magnesium.
His diet is:
4 flakes of orchard grass hay (1 flake am, 1 flake noon, 2 flakes pm)
1 scoop Strategy GX (about 2.5 lbs)
2 scoops Accel Lifetime
4 oz. Quiessence
2 oz. MSM (10,000 mg)
1 cup Aloe Vera Juice
1 scoop Strategy GX
4 oz. Quiessence
18 mg Melatonin
handful All-in-One (gives the melatonin something to stick to!)
In addition, he gets 4 cups of beet pulp, soaked, at a random time.
He's allergic to flaxseed, so I switched from Ultium to Strategy and from Platinum Performance to Accel Lifetime in June. His weight and his body condition are both excellent.
Sometimes the form of Mg does matter. For my mare, Quiessence did NOTHING even at a double dose, but epsom salts helped her a ton and within a very short time. This was for muscle tension and IR issues, but the ability to absorb and use the Mg was very very different with the two forms.
So, I would just try a different form of Mg, something other than MgOxide.
Yes, I worked at a dairy farm for 3 years, and I was amazed at how precise and drilled in the diet is. They can't take chances on a magnesium supplement not delivering what it says it will.
Libbey isn't getting it right now, but she was getting a heaping teaspoon once a day. She's 950 lbs. I think the dosage is 10,000 mg. for the average sized horse dealing with metabolic issues. And I believe that 1 flat, Tablespoon is 10,000 mg. but I didn't feel Lib needed that much.
Thanks A2. One aspect of being dyslexic (in my case, the dyscalculia is much more of a problem) is that I cannot remember numbers for very long. Drives me nuts! You should have seen me scribing for the lay judge at a recent CTR. She kept watching me write the numbers to make sure I didn't reverse any. We laughed about it, but it would have been a shame if somebody lost because I miswrote a number.
I'm hoping Tractor Supply might carry it. I don't know of any local cattle-feed stores. There used to be a lot more dairy farms in the area. It's been hard to see them go out of business. I would occasionally help out in the milking parlor for friends when I was young. I got to clean teats. Joy. The cows seemed to like me--then again, dairy cows like everybody once they've been milked.
just got a 50lb bag of mag-oxide from a co-op feed store for about $38. I had to do a bit of research as far as the amount of mag per ounce. Tracked someone down and they suggested 0.04lb per day, which i believe comes to about .64 ounces.
Excess calcium can interfere with the absorption of Magnesium . I don't know what is in your other supplements, or in your hay, but check that.And IMO ,mag oxide does not seem to be utilised as well as a chelated form such as than mag citrate or mag sulfate.
