Overview
This USDA organic milk thistle capsule is standardized to 80% silymarin, using a 300mg extract the brand describes as a 30:1 concentration equivalent to 9,000mg of raw milk thistle. The 60 capsule bottle is framed as a 60 day supply for liver support.
Standardizing to 80% silymarin controls potency batch to batch rather than relying on raw powder alone. The listed 30:1 ratio explains how a 300mg capsule is meant to represent a much larger quantity of raw herb, and the allergen free label covers all eight major allergens.
- 300mg of 30:1 concentrated extract
- Standardized to 80% silymarin
- Free from all eight major allergens
- 60 capsules, about a 60 day supply
Who it's for
Fits adults wanting a concentrated, allergen free milk thistle extract for daily liver support taken once a day. Not built for anyone wanting a lower potency extract or a shorter supply cycle.
