Buying Guide

Identify the target issue

Choose a formula aimed at the horse’s primary problem—anxiety, training focus, muscle tension, or ulcer support—for better results

Check active ingredients

Look for proven actives such as magnesium, L-tryptophan, thiamine, or natural clays and botanicals that match the intended effect

Consider delivery form

Pellets, powders, and clay differ in dosing and feed mixing—pick the form your horse accepts and that fits daily management

Review dosage and serving size

Compare recommended daily amounts and container weights to estimate ongoing cost and ease of use for your herd size

Mind concurrent medications and conditions

Consult a veterinarian if your horse is on other treatments or has metabolic, ulcer, or pregnancy concerns before adding supplements
