Echinacea Elite
60 vegetarian capsules
Item Catalog Number: 02433
Echinacea has been used to support the immune health for centuries. But there’s more than one kind of echinacea—and the various compounds that help your body protect itself are found in different parts of the plant. The solution: make an echinacea supplement from the two most efficacious echinacea species: Echinacea purpurea and Echinacea angustifolia—and use standardized, whole-plant extracts.
Benefits at a Glance:
The active compounds in echinacea, including echinacosides, alkamides, and phenolic compounds encourage an active, healthy immune response in a variety of ways: pre-clinical studies indicate that echinacea encourages natural killer cell activity.1-4 NK cells are your body’s first, immediate response to previously unknown immune challenges. This makes them an invaluable part of both seasonal and year-round preparedness.
Both species of echinacea (E. purpurea and E. angustifolia) have been shown to also help lessen the duration and severity of immune challenges. Clinical studies also indicate that supplementing with echinacea may give you a better chance of staying healthy all season long, as well.5
Cytokines are a family of chemical compounds released by immune cells. Echinacea compounds can help inhibit these cytokines, which supports a healthy immune response.6,7 And the better your immune system is working, the easier it will be to stay healthy.

Echinacea is a flowering plant native to North America that has been used for centuries to support immune health. Modern research has identified numerous active compounds including alkamides, polysaccharides, glycoproteins, and caffeic acid derivatives. Echinacea enhances phagocytosis, increases natural killer cell activity, supports cytokine production, and may help modulate inflammatory responses.
Echinacea is most commonly used at the first signs of immune challenge. Research suggests echinacea is most effective when started early and used consistently throughout the duration of immune challenge, typically 7-10 days. Some people use it preventively during high-risk periods, though long-term continuous use beyond 8 weeks is generally not recommended.
A meta-analysis of 14 studies found that echinacea reduced the odds of developing colds by 58% and shortened cold duration by 1-4 days. Studies using standardized extracts with adequate doses tend to show better results.
Echinacea has an excellent safety profile for short-term use. When side effects occur, they're typically mild - minor GI upset or allergic reactions in those sensitive to Asteraceae family plants. People with autoimmune conditions should discuss use with healthcare providers.
Echinacea combines well with other immune-supporting nutrients like vitamin C, zinc, elderberry, and vitamin D, which all work through complementary mechanisms.
Results: Meta-analysis of 14 studies found echinacea reduced odds of developing colds by 58% and decreased cold duration by 1.4 days average.

Results: Echinacea purpurea extract increased phagocytosis by 20-30% and enhanced natural killer cell activity in vitro and human studies.

Results: Early echinacea treatment reduced symptom severity and duration more effectively than delayed treatment, supporting "use at first sign" approach.
