In 30 days my mares attitude has changed. She is much more relaxed and is eating her grain much more slowly. And the big difference is when she travels. Her anxiety over the new horses in her surroundings is reduced. She even made friends with the gelding in the stall behind her.

Calming that targets the mind, stomach, and hindgut

Many horses displaying anxious behaviors could, in fact, be dealing with ulcers - a common but often underdiagnosed concern. That’s why Formula 707 created Support Pro, part of our Professional line, to provide a truly all-encompassing solution that raises the bar in equine care. This advanced formula combines our trusted calming blend with the powerful ULZERless formula for optimal gut health, while the Digestive Health blend delivers essential prebiotics and probiotics to nurture a healthy and balanced hindgut.

The benefits of combo daily packs

Support Pro is the ultimate solution for streamlined nutrition, offering our premium formulas in 28 convenient, single-serving daily packs. These "combo packs" simplify the process of providing your barn with a balanced Formula 707 supplement, making it both effortless and cost-effective. You'll save per serving compared to purchasing each component separately in their largest sizes and mixing them yourself!

To minimize waste, each 28-day supply is thoughtfully packaged in a compact box.

Could it be more than a calming issue?

Sometimes, what seems like a behavioral or "calming" problem in horses is actually a sign of discomfort caused by ulcers. Horses with ulcers often exhibit behaviors that overlap with anxiety, making it easy to miss the underlying digestive problem. Here are some behaviors to watch for:

Pacing or stall walking

While these can be signs of restlessness or boredom, they might also indicate discomfort from ulcers, especially if the horse seems particularly agitated at feeding times.

Tail swishing or ear pinning

While these can be signs of restlessness or boredom, they might also indicate discomfort from ulcers, especially if the horse seems particularly agitated at feeding times.

Overreaction to stressors

Increased spookiness or a hyper-alert state can seem like a need for calming supplements but might stem from the pain and discomfort of ulcers heightening your horse’s sensitivity.

Decreased appetite

If your horse is hesitant to eat or leaves food behind, it may not just be picky eating. Ulcers can make mealtime uncomfortable, leading to frustration, irritability, and even nervous behaviors around feeding time.

This is why we recommend Support Pro as a preferred choice for horses that need truly comprehensive calming support.

FAQs

What's the benefit of buying a combo pack?

Combo packs offer multiple benefits. Firstly, they offer convenience with pre-portioned servings that are easy to pack away for shows, trail rides, or wherever else your horse may be going. Additionally, they keep each serving of pellets as fresh as possible. Lastly - it's less expensive to purchase combo packs than it would be to buy each of the "component" products in the largest sizes possible.

I have a huge program I'd like to put on this product. How do I best do that?

Please reach out to our customer service team (info@formula707.com) for bulk pricing on orders over 500 lbs.

How do I add my horse's name to my order?

Simply add your horse's name at the top of this product page and apply it. To confirm the horse's name is on the product, check the cart. It will appear under the product name. For multiple horses, add one box to your cart at a time. Your box will arrive labeled with your horse's name.

What's the difference between Support Pro and Calming?

Support Pro IS Calming - blended along with our Digestive Health and ULZERless formulas. If you're looking for total gastric & GI support along with calming - Support Pro is your choice! Plus, it provides a double "therapeutic" dose of ULZERless, which is powerful for the control of gastric issues in horses that may suffer from ulcers.

If it's called "Formula 707 Professional" - do I have to be a professional to purchase it?

No! These Formula 707 Professional combo packs can be purchased by anyone - regardless of status in our Professional's Program or overall amateur/pro status.

What packaging does this arrive in?

Our Formula 707 Professional combo packs are shipped in sturdy boxes. Some of our customers opt to purchase a bucket to store, others use another container around the barn, and some store in the box itself. It's up to you!

Why 28 packs?

Since every month has a different number of days, 28 packs is roughly a month's worth. Most of our customers put their packs on a subscription to make sure they have a constant supply!

Since 1946, our business has been built on trust. That’s why we proudly share every piece of customer feedback - good or bad - right on our website. 

Because horse owners deserve full transparency when it comes to what they feed.

Turned skeptics into believers…

I, along with others, assumed this was going to be wasted money.

My gelding was purchased semi-sight unseen at a sale as a diamond in the rough . He was skinny, sucked up, but what I didn’t know was that he was dangerously anxious and reactive. He supposedly had 60 days of riding. Once I got him home you could literally see his body ripple with anxiety. He would double barrel kick out, run you over, try to jump fences. It was bad. It took a long time of lunging just to tack up and ride.

I was desperate for something to help us. I was ready to give this horse away to someone with death wish. I bought this with the expectation that it would flop. Thank goodness I was wrong, so wrong.

After 3 days on this product there was a noticeable difference. He was bright eyed, alert, easily caught, willing. Everything you’d expect of a talented, well handled but freshly started 4 year old. Training him actually became enjoyable again. His brain was on, there was progress with every ride. He still has his moments like any young horse would but settled quickly.

We’re now 2 months in with this product. He’s gained weight, filling out, looks comfortable and looks great overall.

We just got home from our first 2 day ranch versatility show. I couldn’t be more proud. He had his first show jitters ( we’ll be honest, caused by me) but he performed as he should at his age and level AND STAYED SANE!!! My goal was just to get in the arena and have minimal issues. However, we ended up 3rd overall in our division for high point which I feel is a testament to just how beneficial this product is for these high anxiety horses.

Everyone that knows what we’ve been through now rave about your product.

Thank you 707!!!

Actually works!

I’m so glad I found a supplement that actually calms my horse and keeps her much more level headed. She eats it great and the packets are super handy. I wish I’d found it sooner for my previous horse!

Life changing

Our daughter has been riding for about 5 years. We recently purchase a horse for her and as the summer goes on his showing becomes less predicatable. This 707 Pro supplement has been life changing for her. It has allowed him to trailer easily, and show with less "stress," whether that is stomach stress or emotional. She shows more confidently knowing that he is supported with the supplements he needs. He searches for this supplement in her back pocket- because he also LOVES the way it tastes.
