Formula 707 Calming Equine Supplement 10 lb Bag – 80 Servings – Anxiety Relief and Enhanced Focus for Horses – L-Tryptophan, Thiamine & Magnesium

707 has taken the edge off of my daughters barrel horse.I have a 5yr old speed racking horse that has had extensive ground work and worked being desensitized but remained spooky under saddle. 707 has calmed him down to now, he does not jump out of own skin when riding. I highly recommend this product.

Works great! Just as advertised. I use it when I take my horse on a trip to reduce any anxiety she may have with the travel and new places.

Great product! Works very well with my 10 year old gelding. He was anxious playing a bit too rough with my 30 year old mare. This product is just enough to take the edge off. Everyone is much happier now that he is a calmer version of himself.

Excellent product. My horse is calm and has no more ulcer problems

Didnt work on everyone but great on those it does

Works great for a nervous horse. I use it when we travel far from home for rodeo. Doesn't sedate just takes the edge off. Can still compete with it. It has a scoop for measuring too. Pricy but needed. And the bag will last probably all year.

Within one week of starting this my horse went off his grain and hay. So I had to dig deeper into what was in it. My horse is allergic to Sulfur. I called customer service, asked do this has any Sulfur or any type of sulfates. She proceeded to ramble off the active and inactive ingredients. I repeated the question again slightly different, and got the same answer. I said ok thank you. I looked up the 2nd active ingredient, thiamine. Turns out it is a sulfur-containing derivative of thiazole and pyrimidine. Bingo! So 3 stars for the product since customer service don't know their product well enough. I thought I used this before with my horse, but apparently it was a different company's Magnesium.

We noticed a big difference in our horse! Best money ever spent!!! Very happy with this product.
