Shiitake Mushroom

Overview

Shiitake mushroom (Lentinula edodes) is both a popular culinary mushroom and a valued medicinal food. It is rich in beta-glucans, polysaccharides that support immune function, and provides a rich umami flavor to dishes. Shiitake contains eritadenine, a compound that may support cardiovascular health, and is a good source of B vitamins including niacin (B3), which supports NAD+ synthesis and mitochondrial function. The mushroom also contains lentinan, a beta-glucan that has been studied for its immune-modulating properties. Shiitake is widely used in cooking and can be consumed fresh or dried.

Substances

2 substances in this food

Beta-Glucans

Polysaccharides with immune-modulating properties found in mushrooms and other foods

Vitamin B3 (Niacin; Niacinamide)

NAD+ precursor; supports mitochondrial biogenesis and ATP production

Preparation Notes

• Can be consumed fresh or dried; dried shiitake have a more concentrated flavor
• Rehydrate dried mushrooms in warm water before cooking; reserve the soaking liquid for soups and sauces
• Cooking enhances the bioavailability of some nutrients
• Fresh shiitake should be stored in the refrigerator
• The stems are tougher and can be removed or used to make stock

Biological Target Matrix

Biological Target	Substance	Contribution Level	Therapeutic Areas	Mechanism of Action
Gut–Brain Axis & Enteric Nervous System (ENS)	Beta-Glucans	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base	Act as prebiotics supporting beneficial gut bacteria; enhance microbial diversity; support SCFA production; modulate gut barrier integrity
Inflammation & Oxidative Stress	Beta-Glucans	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base, Alzheimer's Disease, Bipolar Disorder	Immune-modulating properties; may help reduce inflammatory responses; support immune cell function; specific beta-glucans like lentinan (Shiitake) and D-fraction (Maitake) have been extensively studied for immune support
Mitochondrial Function & Bioenergetics	Vitamin B3 (Niacin; Niacinamide)	Contextual / minor contributor	ADHD, Anxiety & GAD, Depression & MDD, Postnatal Depression (PND / PPD) — Evidence Base, Alzheimer's Disease, Bipolar Disorder	Replenishes NAD+, supporting oxidative phosphorylation, sirtuin signaling, and mitochondrial biogenesis; key for neuronal energy metabolism
