Levothyroxine for horses was introduced by LLOYD in 1965 as iodinated casein powder, Thyrone, and was replaced with Thyro-L in 1996. LLOYD developed the Levothyroxine Sodium Powder specification monograph for USP. It is the only (levothyroxine) USP powder available for horses.
Only Thyro-L meets the higher powder, USP standard for an oral pharmaceutical powder and can make this claim on the front mast of its label. Check the label of any other T4 powder product. You will see that it only contains Levothyroxine Sodium USP as a listed ingredient [Levothyroxine Sodium USP (0.22%)], which simply indicates a type of raw material.
A lifetime med for my IR walker, her sugars in control with diet and exercise, powder mixes easily with soaked Timothy pellets.
This product put the blood values for my off-the-charts insulin resistant mare squarely in the normal range. Big change in her personality too
I have had my mare on Thyrol-L for a few years. It helps her with her metabolic issues. I like to buy my supplement in bulk, if possible, to save money on price and shipping. Chewy was easy to order with, my vet was notified to verify the prescription quickly and it arrived fast.
Need this for my horse Howie and Chewy has the best price for it. THANK YOU!!
This mixes well with some grain and my picky girl gets her medicine.
My horse has been on Thyro-L to help with metabolic problems and when I needed to purchase a new jar, I found that Chewy had it for less money than my usual sources. Approval from my vet was easily handled by Chewy and the product arrived before the tracking date. I'm thrilled with the experience.
Easy to measure, easy to add into damp pellets or cubes, no trouble getting fat pony to eat it.
Chewy had one of the best prices on the internet for Thyro-L, and when I ordered it, it got to me faster than my vet usually delivered! Chewy is my hero!
It is so convenient to get this big container of Thyrol L from Chewy, instead of going to the vet every few months for a small amount. My older, metabolic, horse has really benefitted from this. His coat is better and his muscle mass is better. I was skeptical when the vet advised testing him and starting it, but it works well.
My pony was overweight and sluggish. Since the vet put him on this product, he has dropped weight and is much more active.
