There are four main species deer that are raised and harvested for their deer antler velvet. Each species has different cultural uses and different serving sizes related to their different constituent compositions, ranging from more medicinal concerning immediate benefits to more food-quality and nutrient filled.
Red Elephant Deer
First, sika deer are the most potent and most medicinal. Second reindeer are still quite medicinal, but not quite as potent and containing more nutrients per dosage serving. Third, red deer are more nutrient filled and easy-to-take larger dose servings due to a lower medicinal quality. Fourth, elk are food-grade nutrient filled deer that do not have much of the capacity for the medicinal qualities.
