Schisandra is a natural adaptogenic stimulant berry used in traditional Chinese medicine. It increases energy, improves physical performance, enhances immunity, and improves cognitive function.

And unlike high caffeine use, it doesnt adversely affect the adrenal galnds. Its available in capsules, tincture and tea, and effective dose is 130 mg per day.
