Are the ingredients sourced in the United States? If not, from where? Thank you.

Answer by ChewyJan 21, 2021
All of Formula 707's ingredients are purchased from U.S. companies (either manufacturers or distributors) who have been fully vetted according to their Standard Operating Procedures that align with cGMPs established by the FDA. With that being said, many vitamins and amino acids are produced exclusively overseas (New Zealand, China, etc.) and then held by these U.S. distributors. As an example, Green Lipped Mussel is sourced and harvested exclusively in New Zealand – there is no domestic source of this ingredient. In order to ensure that all of their ingredients are up to their standards of quality and potency, Formula 707 audits the sourcing activities of their U.S. distributors, and submit ingredient samples to accredited third-party testing facilities prior to including them in the products.

I was skeptical but adding this supplement to my OTTB senior I saw a difference in his comfort almost immediately. Consistency is key and discovered this when I ran out in between shipments.

It came in smashed container

It came in a smashed box! So I could not feed it, there was broken plastic everywhere in broken open bags. I threw it out in disgust.

Package and working

We noticed a difference with our 29 yr old when we start him on this stuff he has ringbone and arthritis and my mare has some issues we had tried buteless with him and devils claw but when we started this I looked up top supplement for his problems and this came up so I figured what can I loose. After 4 days my husband and daughter noticed a difference in him. So I get a tub for both now.

My horse has arthritis in his hind legs and I have tried many supplements but I found after using this product he is moving so much better and actually goes into a little trot. He is a quarter horse 24 years old. He has no problem with the taste of the supplement and to date he has been on it for over a year with the best results of anything else I tried. I also feel that the price is manageable

This is a great joint supplement. It took 3 months to really notice a difference, but my horse’s lameness has subsided. These are tasty to my horse, he eats them

My 22 yo gelding is doing nicely on this - he sustained a deep digital tendon injury after surgery and PRC I was able to ride him again for a few years. Now he’s my pasture pet but shows some difficulties due to age and past injury - I’m very happy with the results even in the early stages, it must be pretty palatable because he’s my picky eater and gobbles it up without hesitation.
