Denim · Day 90 on Osteo-MAX Denim, Day 90 on the Osteo-MAX and Gut X protocol
Common Questions

The 1 + 1 ships one gallon of Osteo-MAX, one gallon of Gut X, and 2 calibrated pumps, one for each jug. Each gallon is up to a 4-month supply at the maintenance dose, so the two run out together.

The 2 + 2 ships two gallons of each with 4 pumps. The 4 + 4 ships four gallons of each with 4 pumps, two per product.

Gut X handles the gut: absorption, gut health, and immune response. Osteo-MAX handles the structure: bone, joint, and connective tissue. Structural nutrition only counts if the gut can take it up, which is why these two are the foundation the rest of the protocol builds on.
Both are liquids, top-dressed on the feed you already give. Osteo-MAX: load at 2 pumps a day, then hold at 1 pump a day. Gut X: load for the first 30 days at 2 pumps a day, then hold at 1 pump a day. One pump is one ounce, so there is no scooping and no guesswork.
Both are palatable liquids that coat the existing ration, so most horses accept them with no fuss. If yours is especially fussy, our equine nutritionists help you transition, included free with every order.
Because this combo contains Gut X, a qualifying subscription makes your horse eligible for the $20,000 Colic Surgery Coverage Program: complete the enrollment form, and once accepted, eligible colic-surgery costs are reimbursed up to $20,000 per horse (lifetime) with a $0 deductible after a 30-day qualifying period. One-time orders ship without Colic Surgery Coverage. Colic Surgery Coverage is a reimbursement program, not insurance, and is not a health claim.
Anytime. Manage everything in your account or by SMS: pause, change delivery dates, or cancel with no fees and no phone tree.

Many owners notice changes from Gut X within 7–14 days, most often in body condition, appetite, manure quality, and coat shine. Osteo-MAX works on a longer clock: most owners report changes in movement, comfort, and willingness to work within the first 30 days, and bone remodels slower still, which is why the loading phase runs 30 to 60 days for bone support.

Neither is a short-term protocol. Both are built to be fed daily as long-term support.

And if you don’t see the difference, you’re backed by our 90-day money-back guarantee.

Osteo-MAX + Gut X · The Foundation Stack

Bone, joint & connective tissue,
on a gut that can use it.

Bone & Joint SupportConnective TissueGut & Immune Support

Osteo-MAX is bone, joint & connective tissue support. Gut X supports gut health & triggers immune response. Fed together they cover the two halves of the same problem: what you put in, and what your horse can actually take up.

Both are delivered in a proprietary liquid form with up to 99% availability1, 2. Powders & pellets must first break apart, hydrate, & disperse inside a moving gut, a slow, variable process that leaves availability as low as 2.5%3.

“I’ve been AMAZED with both Osteo-MAX + Gut X. After only 4 weeks of using Osteo-MAX the x-rays have shown significant improvement already. It’s so wonderful to have a happy, healthy horse again!”

Load with 2 pumps a day for the first 30 days, then settle into 1 pump a day.

  • Pump it straight over the existing ration. The liquid coats the feed, so picky eaters take it without a fight.
  • One gallon is 128 maintenance doses, up to a 4 month supply for one horse.
  • The loading phase runs about 30 days.

Most owners notice manure quality, appetite and coat changes in the first week. Gut lining support keeps compounding, with full benefit typically by month 6.

  • Day 1 to 30, the loading dose is doing the work.
  • Day 30 onward, one pump a day holds it.
  • This is daily long-term gut and immune support, not a quick fix.

Gut X is delivered in a proprietary liquid form with up to 99% availability1,2. Powders and pellets must first break apart, hydrate and disperse into usable surface area inside a moving gut, a slow, variable process that leaves availability as low as 2.5%3.
