We don't recommend adding ARMRA Colostrum™ to anything hot. Many of the living, bioactive nutrients in ARMRA Colostrum™ are heat-sensitive, so adding ARMRA to a hot beverage denatures these compounds and negates its efficacy. We recommend taking ARMRA Colostrum™ by either pouring the unflavored powder directly into your mouth or mixing our powders with your cool/lukewarm beverage or food.
