PEAK PERFORMANCE SOLACE Solace (formerly Ex Stress) is an all natural, herb free formula to help your horse handle the stress of travel and competition. Since sugar can make a nervous horse even more tense, Solace is completely sugar free. You'll find only concentrated levels of B vitamins and magnesium in this calming product. This formula is available in a daily, easy to feed powder, which will not break down as quickly as liquid vitamins are known to do. Solace succeeds where other products have failed.
