Current Nerve Fresh label entry

Althaea officinalis root powder
220 mg

Amount shown per 2-capsule serving on the current product label supplied to this site.

What marshmallow root is

Althaea officinalis is an herb whose root contains substantial mucilage polysaccharides. It has a long history of use in herbal preparations for irritated mucous membranes and dry cough.

What research focuses on

Modern literature often examines polysaccharide structure, antioxidant activity and traditional respiratory or mucosal uses. That evidence base is quite different from a clinical trial testing nerve symptoms.

Evidence limits

Finding antioxidant or biological activity in laboratory research does not establish a clinically meaningful effect in a finished multi-ingredient supplement. Dose, extraction and study population matter.

What this means for Nerve Fresh

The current label confirms marshmallow root powder as part of the formula, but this site does not claim marshmallow root proves Nerve Fresh can treat neuropathy or repair damaged nerves.

Evidence limits

Ingredient evidence is not finished-product evidence.

Even when an ingredient has promising research, that does not establish the effectiveness of Nerve Fresh as a complete formula. Form, dose, standardization and the studied health outcome all matter.
