2025 Expert Guide: Top 5 Chelated Mineral Feed Blocks and Tubs for Horses in Canada - Verified Options for Reliable Free-Choice Supplementation (Which One Suits Your Herd?)
Published on Monday, August 25, 2025
Slow-release feed blocks and tubs fortified with chelated minerals and electrolytes provide free-choice supplementation for pastured or stalled horses. These formats are popular in Canada because they deliver consistent mineral intake with minimal labor, support herd supplementation without daily dosing, and are formulated for weather resistance and palatability. Horse owners often choose chelated mineral blocks and tubs to improve mineral bioavailability, reduce mineral antagonism common in some soils and forages, and help manage hydration and recovery with added electrolytes. For Canadian conditions where regional forage mineral profiles vary and winter stress increases nutritional needs, these products offer a convenient, cost-effective way to maintain herd mineral balance and overall condition.
Top Picks Summary
Purina Free Balance 12:12 Vitamin and Mineral Block
Purina Free Balance 12:12 is a widely distributed, cost-effective free-choice block designed for broad use in equine populations, offering a balanced 12:12 calcium:phosphorus ratio and fortified vitamins with chelated trace minerals for improved bioavailability. Its market-leading advantage is broad availability and consistent formulation that typically costs less per horse-day than specialty options, while providing a dependable baseline compared with more targeted or pelleted products on this list.
$25-45 CAD
Hoffman's Horse Mineral Block with Chelated Trace Minerals
Hoffman's Horse Mineral Block is positioned as a premium chelated-trace-mineral block, formulated to maximize uptake of iron, zinc, copper and selenium candidates that can be antagonized in raw forage; this technical focus gives it an absorption edge for horses with marginal mineral status. Although typically priced higher than generic blocks, its laboratory-backed chelation strategy can reduce the need for extra supplementation and offers a targeted alternative to bulk or pelleted regimes on the list.
$20-40 CAD
Brooks Feed B-W-S Block Plus
Brooks Feed B-W-S Block Plus is a budget-minded, salt-balanced mineral block enhanced with chelated trace minerals to improve uptake while keeping unit price low for large herds. Its principal advantage is low cost per head and ease of use in extensive operations, offering many of the mineral benefits of premium blocks like Hoffman's but at a scale and price point that competes strongly with mainstream offerings such as Purina and Masterfeeds.

Why Chelated Minerals and Slow-Release Formats Work - Evidence and Practical Takeaways
Chelated minerals are bound to an organic carrier, which research and industry guidance indicate can increase absorption compared with many inorganic mineral sources, especially under conditions where mineral interactions or poor forage quality limit uptake. Slow-release blocks and tubs promote steady, voluntary intake so horses receive supplemental minerals throughout the day rather than in a single bolus, which helps stabilize blood mineral levels and supports functions such as hoof growth, immune response, and electrolyte balance. Key authoritative references in equine nutrition include the NRC Nutrient Requirements of Horses and peer-reviewed studies comparing mineral forms and bioavailability; equine nutritionists also recommend pairing free-choice supplementation with forage testing and observation of consumption patterns.
Chelated mineral forms often show improved intestinal absorption and lower fecal excretion compared with some inorganic salts, improving efficiency of supplementation.
Slow-release delivery reduces peaks and troughs in intake, supporting consistent trace mineral and electrolyte availability for maintenance, performance, or recovery.
Research and practical guidance link adequate trace mineral status to better hoof integrity, coat quality, reproductive health, and immune function in horses.
Electrolyte-fortified tubs support hydration and recovery after work or heat exposure; free-choice formats help maintain intake when water or forage quality varies.
For best results combine free-choice blocks or tubs with regular forage analysis and veterinary or nutritionist guidance to match the product to life stage, workload, and regional soil deficiencies.
