Life Data Labs Farriers Formula Refill 11lb Bag

Excellent product. I've been using this for years and won't use anything else. Both of my thoroughbreds love it and their hoof quality speaks for itself.

This is the gold standard for hoof supplements in my opinion. It's pricey, but it works. I generally think using (most) anything else is pouring money away. I've used FF on my own horse and many, many others going back many years of grooming and working in barns. On some, you can literally see the difference. On those with feet that are in decent shape to start with, I find that there is greater growth between cycles, even in winter. With regards to my current horse, both my vet and farrier say "whatever you're doing, keep doing it" almost every time I see them -- and he's a thoroughbred with thoroughbred feet.
