Organic Shiitake Mushroom Extract Powder

Most Shiitake products on the US market are non-extracted powders or blends containing mycelium grown on grain. While these may contain some nutritional value, they often deliver low levels of bioavailable medicinal compounds.

Dr Noel’s Shiitake is a true extract made from 100% fruiting bodies, specifically chosen because the fruiting body contains the highest concentrations of beta-glucans, lentinan, sterols, and eritadenine.

By focusing on extraction rather than raw powder weight, this product delivers consistent potency, improved absorption, and greater physiological relevance.

Shiitake mushrooms contain a tough fungal cell wall composed of chitin, which the human digestive system cannot efficiently break down.

Extraction is important because it:

• Breaks down the chitin structure
• Releases beta-glucans and polysaccharides
• Improves bioavailability
• Concentrates active compounds into a usable form
  

Without extraction, much of Shiitake’s medicinal value passes through the body unused.

Beta-glucans are complex polysaccharides found in the cell walls of medicinal mushrooms. In Shiitake, they are particularly well studied.

They are associated with:

• Immune system modulation
• Support for immune cell activity
• Balanced inflammatory response
• Long-term immune resilience
  

Dr Noel’s Shiitake extract contains verified levels of beta-glucans, confirmed through laboratory testing rather than estimated from raw material.

Lentinan is a specific beta-glucan uniquely associated with Shiitake mushrooms. It has been studied extensively for its immune-modulating properties.

Lentinan helps support:

• Immune signaling pathways
• Balanced immune responses
• Cellular defense mechanisms
  

This compound is one of the key reasons Shiitake is regarded as a foundational immune-support mushroom rather than a simple dietary ingredient.

Shiitake contains a unique combination of beta-glucans, sterols, and eritadenine that work together to support cardiovascular function.

These compounds help:

• Support healthy cholesterol metabolism
• Promote vascular health
• Support normal blood pressure
• Reduce oxidative stress affecting the cardiovascular system
  

This makes Shiitake a valuable mushroom for individuals focused on long-term heart and metabolic wellbeing.

The recommended dosage is 1/ 4 -1/2 teaspoons (about 1-2 grams) per day. It's best to start with a smaller dose and gradually increase as needed.

This product is ideal for individuals who:

• Want immune and cardiovascular support
• Understand the importance of extraction
• Avoid mycelium-on-grain products
• Value science-backed medicinal mushrooms
