Farnam SandClear Psyllium Crumbles Supplement for Horses

Best for horses in sandy environments that graze on pasture or eat off the ground. This supplement emphasizes a premium psyllium husk formulation to aid in the removal of sand from the ventral colon and support digestive health. The product is suitable for daily use as part of a routine to reduce the potential for sand colic. Caution: monitor intake for horses with sensitive digestion and adjust as advised by a veterinarian or equine nutritionist.
Farnam SandClear Crumbles, Psyllium Digestive Health Supplement (20 lb)

Best for larger operations or horses needing an extended supply, this 20 lb option supports removal of sand and dirt from the ventral colon via premium psyllium husk. It’s well-suited for ongoing programs in sandy arenas. Choose this if you prefer a longer-use bag and consistent digestive support. Limitation: dose frequency should align with the horse’s dietary plan to avoid over-supplementation.
Farnam SandClear Crumbles, 10 lb (32 day supply)

Best for smaller barns or horses with lighter sand exposure requirements, this 10 lb option provides essential sand-removal support with premium psyllium husk. Choose this if you need a compact starter or trial size. Limitation: smaller bag means more frequent restocking for larger horses or high-traffic arenas.

Best for stable, long-term sand management, this 50 lb bag delivers consistent psyllium-based digestion support. Ideal for programs that require bulk supply, especially in barns with multiple horses. Limitation: heavier to manage and store, requiring proper storage to maintain freshness.
Equerry’s Sand Master Horse Supplement

Best for riders seeking a broader digestive health profile along with sand clearance, this psyllium-based supplement includes bran, vegetable oil, yucca, microencapsulated probiotics, digestive enzymes, and yeast. It supports fecal sand clearance and overall gut balance, making it suitable for horses with appetites or digestion concerns. Caution: blends with probiotics may require gradual introduction to avoid transient digestive upset.
Buying Guide: Key Purchase Considerations
- Sand exposure level: For horses that graze on sandy ground or train on arenas, prioritize products with a strong psyllium basis to physically help move sand through the digestive tract.
- Size and frequency: Consider bag size in relation to your horse’s weight and daily intake. Larger bags are more economical for multiple horses; smaller bags are convenient for single-horse barns or trial purposes.
- Digestive health features: Some blends include probiotics, enzymes, or other fibers. If your goal is broader gut health alongside sand removal, these options may be preferable.
- Administration and palatability: Flavor (apple/molasses) and texture influence acceptance. Ensure your horse readily accepts the supplement to maintain consistent dosing.
- Storage and handling: Large bags require appropriate storage to prevent moisture and contamination. Check packaging durability for easy dispensing.
- Veterinary guidance: Always consult a veterinarian or equine nutritionist when starting a new digestive supplement, especially for horses with a history of colic or digestive issues.
FAQ

They complement proper arena maintenance and grazing management but do not replace good management of footing and grazing areas. - Which option is best for a large stable with multiple horses?
The 50 lb Farnam Sand Clear or the 20 lb Farnam variants are practical for stable-wide programs, depending on total horse count and dosing needs. - Is Equerry’s Sand Master suitable for horses with sensitive digestion?
