This is wonderful, wonderful stuff, and although this may sound dramatic, asks like a transfusion on my mare.
I've used Feedmark for many years, and a while ago now, went through a bad patch where I couldn't afford her Extra-flex
Within a couple of weeks she became stiff, and sore, and grumpy. She stopped rolling, and stopped cantering too. At first I didn't make a connection, and thought she was ill.
The vet came out, and, after numerous tests, scans, x-rays and injections, put it down to age and the onset of arthritis, and gave me a well known joint supplement.
After three months on this, without any improvement, I managed to afford to get her Extra-flex.
Within 10 days she rolled in the field, and four days later started cantering in from the paddock. I couldn't believe it, and yet I think all along I'd known.
She's been on Extra-flex with Rosehips for many years now, looks great, and
behaves like a youngster, people often muddle my two horses up, and think she is the younger one!
She will stay on Extra-flex now for the rest of her life, as I wouldn't ever consider not giving it to her, and certainly wouldn't change to anything else!
