AI pick (line): Mad Barn Omneity

It is a concentrated vitamin and mineral premix designed to balance forage-based diets at a small feeding rate, with no added sugar or filler.

Not for: Horses already eating the full recommended amount of a fortified commercial feed.

Grand Meadows Grand Vite (line)

It is a widely available all-round multivitamin and mineral for horses on hay or pasture.

Not for: Horses with a hay analysis that shows specific imbalances needing a targeted mix.

Feeding rate vs. concentration: Compare the amounts of copper, zinc, selenium and vitamin E per daily serving, not per pound of product. Products with low feeding rates can deliver much more nutrition per scoop.
Vitamin E for horses without pasture: Supply at least 1 IU per kg of body weight daily when the horse has no fresh grass. Vitamin E degrades quickly in stored hay.
Selenium by region: Match selenium to whether your area's soil is deficient or high, and count every source. Both deficiency and toxicity occur, and the safe range is narrow.
Iron: Prefer products with little or no added iron. Forage diets usually supply plenty of iron already.
Copper to zinc ratio: Look for roughly a 1:3 to 1:4 copper to zinc ratio. Imbalance between these minerals interferes with absorption.

Both balance forage. Balancers add protein and are fed by the pound, while powders are fed by the scoop and add minimal calories.
