How long does it take to see calming results

Answer by ChewyFeb 04, 2021
When taking this supplement, your horse should start seeing results after the 8 day loading dose. For complete feeding instructions, click on the 'Feeding Instructions' tab, next to the 'Nutritional Info' tab, just under the product photos.

Does this supplement work as an electrolyte as well?

Answer by ChewyNov 05, 2020
This supplement can be used as an electrolyte due to the ingredients magnesium, calcium, sodium, and potassium that are in the product. However, the Apple A Day is a more complete formulation for electrolytes while the Thia Cal is geared towards nervous horses.

Can this be used for dogs

Fed X left it at the barn which is not close to house !! I already talked to customer service on this and they were supposed to contact fed x. So if that carrier is who you use I’m not seeing me ordering from you much or any more . Can’t count on getting my packages from fed - x , ups or mail gets me my packages but any retailer that uses fed X will avoid

Really helps take the edge off for anxious horses

My mare had a rough childhood and can get pretty anxious and reactive when stressed. I got her this to prepare for moving, and I really think it helped her transition

My mare had a rough childhood and can get pretty anxious and reactive when stressed. I got her this to prepare for moving, and I really think it helped her transition. She didn't act drugged or anything, just more relaxed and less reactive. I'm considering keeping her on it for longer to see if it helps her in general. For what I've seen so far, I would recommend this and feel it works well.

I’ve used this before on an other horse and he loved the taste. Aurora is quite the spooky one and I thought I’d give it a try. She loves the taste and it seems to calm her down. I do mix it with organic raspberry leaves as well because she’s an Arab/Appy mare and can be a real handful.

THI-CAL

I owned a leopard appaloosa who was anxious, spooky and it made him difficult to ride safely. I heard about a condition in horses that lacked vitamin, Thiamin one

I owned a leopard appaloosa who was anxious, spooky and it made him difficult to ride safely. I heard about a condition in horses that lacked vitamin, Thiamin one of the B vitamins, that caused symptoms like my horse showed. I bought this product and used it daily from that day forward. I had a new horse who was calm sensible and the love of my life. I lost him at 30 years old, but I never missed a dose of Thi-Cal.
