Best Supplements for Older Horses: Five Options for Senior Equine Care
The best supplement for an older horse depends on the need: weight and nutritional support, joint care, hoof and coat support, or broader wellness. Manna Pro Weight Accelerator is best suited to seniors needing extra calories, while Richdel Legacy focuses on joint and connective-tissue support. Horse Health Joint Combo combines joint, hoof, and coat ingredients; Formula 707 offers multi-ingredient joint support; and Hilton Herbs provides broader senior-horse support.
| Product | Best suited for | Listed focus |
|---|---|---|
| Manna Pro Weight Accelerator | Older horses needing weight support | Calories, omega-3s, probiotics, biotin |
| Richdel Legacy Pellets | Senior joint support | Joints and connective tissue |
| Horse Health Joint Combo | Combined joint, hoof, and coat needs | Joint function and hoof growth |
| Formula 707 Joint 6-in-1 | Broad joint-support ingredient coverage | Cartilage, tendons, ligaments, joints |
| Hilton Herbs Senior Horse | Broader senior-horse support | Circulation, joints, muscles, liver, kidneys |
Manna Pro Weight Accelerator

This meal topper is formulated for senior horses and is best for older animals that need added calories to help gain or maintain body condition. Its listed features include high fat and calorie levels, flaxseed-derived omega-3 fatty acids, probiotics, biotin, and controlled starch levels.
The omega-3s are included to support skin hydration and coat condition, while the product’s probiotics are intended to support digestion. Biotin is included for hoof support. It was selected because it addresses several common senior-horse feeding priorities alongside weight support.
Limitation: This is a calorie-focused supplement, so it may not be the right match when weight gain is not a goal. Ask a veterinarian or equine nutrition professional whether its energy and starch profile fits the horse’s diet.
Richdel Legacy Senior Joint Pellets

Richdel Legacy is best for owners seeking a supplement specifically formulated for horses 15 years or older, with an emphasis on joints and connective and soft tissue. Its listed ingredients include glucosamine, chondroitin sulfate, MSM, yucca, ester C, and vitamin E.
Choose this option if senior joint support is the main priority and a pellet format suits the feeding routine. Its age-specific positioning distinguishes it from the Formula 707 product, which is described as suitable for horses of all ages and classes.
Limitation: The supplied product information focuses on joint and tissue support and does not list weight, hoof, or coat benefits. Check the full label for feeding directions and ingredient amounts.
Horse Health Joint Combo Hoof And Coat

This combination product is best for owners who want joint, hoof, and coat support in one supplement. The listed ingredients include glucosamine, chondroitin, vitamin C, MSM, biotin, lysine, zinc, and omega-3 and omega-6 fatty acids. The product description identifies joint function, cartilage, collagen synthesis, and hoof growth as its support areas.
The listed biotin amount is 16 mg per 2-ounce serving. The product is described as combining three popular supplement categories, making it a practical comparison for buyers who prefer a multi-purpose option rather than separate products.
Limitation: Its broad ingredient list may not be necessary if a horse needs support in only one area. Review the full label and serving directions before combining it with other supplements.
Formula 707 Joint 6-In-1 Supplement

Formula 707 is best for buyers seeking a multi-ingredient joint supplement that is not limited to senior horses. The product description says it combines six standalone ingredients and supports cartilage, tendons, ligaments, and joints. Its alfalfa- and wheat midd-based pellets are described as easy to feed and palatable.
Choose this if joint support is the priority and you want a pellet designed for horses of different ages and classes. Compared with Richdel Legacy, its listed description emphasizes broad age suitability rather than a formula specifically for horses 15 and older.
Limitation: The supplied features do not identify the six ingredients or their amounts. Check the package details if you need to compare particular nutrients or avoid specific ingredients.
Hilton Herbs Senior Horse Total Support

This product is best for owners comparing broader support for older horses and ponies. Its listed focus includes the circulatory system, supple joints and muscles, and optimum liver and kidney function. That makes it distinct from products whose descriptions center mainly on calories, hooves, or joint ingredients.
Consider it when the goal is a wider senior-care approach rather than a single-purpose weight or hoof supplement. The supplied features provide several intended support areas, so the product was selected to represent a broader wellness option.
Limitation: The provided information does not specify ingredients, nutrient amounts, or feeding directions. Review the complete product label and consult a veterinarian about suitability for an older horse’s health needs.
Buying Guide: How To Choose A Senior Horse Supplement
What support does the horse need most?
Start with the specific concern. For weight and added calories, compare products such as Manna Pro Weight Accelerator. For joint-focused options, compare Richdel Legacy and Formula 707. Horse Health Joint Combo may suit buyers looking to combine joint, hoof, and coat support, while Hilton Herbs describes broader senior-horse support.
How should age and diet affect the choice?
Check whether the product is explicitly intended for senior horses or is described for horses of all ages. Review the complete feeding directions, ingredient list, and nutrient amounts. Consider the horse’s current feed and other supplements to avoid unnecessary overlap, and ask an equine veterinarian or nutrition professional about diet changes—especially when managing body condition or health concerns.
Which format and claims should you compare?
Compare the stated format, such as pellets or a meal topper, with the horse’s feeding routine. Look for specific listed ingredients and amounts rather than relying only on broad phrases such as “total support.” A supplement should complement a suitable forage-based diet and veterinary care, not replace diagnosis or treatment.

Which listed products focus on senior horse joints?
Richdel Legacy is specifically formulated for senior horses and lists joint and connective-tissue support. Formula 707 also focuses on joints, cartilage, tendons, and ligaments, and is described for horses of all ages and classes.
Is there an option combining hoof and joint support?
Horse Health Joint Combo is described as supporting joint function and hoof growth, and also lists coat-support ingredients. Its product features include 16 mg of biotin per 2-ounce serving.
Can a supplement replace veterinary care?
No. Supplements do not replace veterinary diagnosis, treatment, or a balanced feeding plan. Ask a veterinarian before using one for a horse with health conditions or before combining products.
