There’s not much to say about the actual product itself as it’s just monosodium phosphate I add as the CA:P ratio is poor in my hay. That being said, it used to be little crystals that were easy to handle, scoop and weigh. A while ago the product changed to a white powder that has huge clumps all throughout it. It’s very annoying to have to break it down prior to weighing it and adding it to my horse’s supplements. I’ve addressed this with Madbarn and they hope to go back to the granules eventually.

My horses are finally eating it without balking at it. They get 1 scoop that came with the bag, and I give 1 scoop of wheat bran (same size scoop). My horses won't eat more because of the chalky consistency. Very happy your nutrionist noticed my hay last yr was lacking in phosphorus.

I put in the order incorrectly on the first occasion. I raised it and Mad Barn corrected it and reimbursed me. Then we processed the correct order and it arrived in a timely fashion.

We have been using this product as part of supplementation program. Seems to be of good & consistent quality. Easy ordering and quick delivery.

Was recommended by a horse nutritionist to balance out our hay

Great product, great packaging!

So many scoops, maybe at check out it could ask if you need scoops? I literally have a giant pail full now

WONDERFUL service! Staff is always prompt, helpful, and polite. Phosphorus is easily mixed with damp feed and palatable for our horses. Wish the bags actually came in the 5kg option to reduce packaging waste.
