- Guayusa and lion’s mane are two natural dietary supplements that may have health benefits.
- Usually taken as a tea made from the leaves, guayusa is a plant in the Ilex (holly) family. Lion’s mane is a mushroom, used for culinary purposes, which can also be taken as a supplement.
- Studies have suggested that both have antioxidant and anti-inflammatory properties, alongside other health benefits.
- A new study has found that they might also enhance mood and cognitive function.
Many people take supplements to enhance their health and wellbeing, but while animal studies have demonstrated their positive effects, there is little conclusive evidence of their efficacy in people.
Guayusa is from a tree in the holly family, Ilex guayusa, which grows widely in South America. People have been drinking it as a tea in the western Amazon for centuries.

- antioxidant and anti-inflammatory properties
- supporting immune function
- relieving anxiety and depression
- lowering cholesterol
- cancer prevention or treatment
- controlling blood sugar
