Hello! How are you?

We are Jurgis and Ugnė – forest, natural medicine, herbs and mushroom enthusiasts. We started using extracts three years ago and have been amazed at the gentle, yet powerful results – we can think more clearly, rarely get sick (or it passes quickly). Inspired by this, we decided to share extracts with the world.

Cordyceps – Mushroom for Natural Energy and Stamina

Cordyceps mushroom for natural energy and stamina

Cordyceps CS-4 is a unique cultivated strain developed through solid-state fermentation and is the only form of Cordyceps approved for use in Europe under EU Novel Food regulations. CS-4 is recognised as the closest alternative to wild-harvested Cordyceps sinensis, a fungus that has been valued in traditional medicine for centuries.

Historical accounts describe Cordyceps as a rare and highly prized tonic, reserved for emperors and nobility in ancient China and Tibet. It was believed to strengthen the body, restore vitality, and support longevity. Herders in high mountain regions noticed their animals gained stamina and energy when grazing on pastures where Cordyceps grew naturally, inspiring its widespread use among humans.

Modern research: cordyceps continues to be studied for its effects on energy metabolism, oxygen use, and immune support. Modern research has identified dozens of active compounds, linking this traditional remedy to measurable benefits for performance, recovery, and resilience against stress.

Polysaccharides – CS-4 contains beta-glucans and other complex carbohydrates linked to immune system balance and sustained energy production.

Cordycepin & Adenosine – Active compounds in CS-4 studied for their role in oxygen uptake and ATP production, supporting stamina, recovery, and endurance.

Antioxidants – Naturally occurring antioxidants in CS-4 help protect cells from oxidative stress, supporting energy levels, immune defense, and overall vitality.

Origin

Our cordyceps CS-4 is sourced from China. While China supplies many low-quality mushroom products, it also has a 5,000-year mushroom-growing tradition and some of the world’s most skilled growers. Many top mushroom companies source from China — it depends on who you work with, how well you know your supplier and how much you test their produce.

It took two years of extensive searching to find our current suppliers, and they’re fantastic.
