When taking echinacea gummies, it is essential to take certain precautions. Most brands suggest avoiding taking echinacea on an empty stomach and instead consuming it with food or a large glass of water. Additionally, it is important to not take echinacea for more than a few weeks, as long-term safety has not been extensively studied. It is also important to abstain from coffee, tea, cola, energy drinks, or other beverages that contain caffeine when taking echinacea.
Combining echinacea with caffeinated products can heighten the side effects of caffeine, such as headache, increased heart rate, and nervousness.
