Schisandra extract comes from the red berries of *Schisandra chinensis*, a woody vine with a long history in traditional Chinese and Russian medicine. Practitioners classify it as an adaptogen, meaning it helps the body handle physical and mental stress.
People take it to sharpen mental clarity, sustain concentration, and support steady energy levels. Some also use it to promote healthy liver function, though this use lacks wide acceptance in Western supplement traditions.
The extract is standardized to its active compounds called schisandrins. You can find it in capsule or powder form. Taking it with food helps your body absorb it and can prevent an upset stomach. Doses depend on the specific extract strength, so stick to the label directions.
Mild digestive discomfort is the most common side effect. Schisandra may alter how the liver processes certain medications, including some statins and antidepressants, so check with a doctor before combining them. Avoid it during pregnancy and breastfeeding since safety data is lacking.
