Overview
Swanson's milk thistle supplement provides 500 mg of full spectrum milk thistle per vegan capsule, sold in a 100-capsule bottle and positioned for liver health and antioxidant support.
Full spectrum refers to using the whole milk thistle extract profile in each capsule rather than isolating one compound, the standard approach most milk thistle supplements take. The capsules here are vegan, so anyone avoiding gelatin capsules for dietary reasons can use this version.
- 500 mg milk thistle per capsule
- Full spectrum extract
- Vegan capsules
- 100 capsules per bottle
Who it's for
Suited to people adding milk thistle to a liver support routine who prefer vegan capsules over gelatin ones. General antioxidant seekers may also consider it, though it is positioned around liver health rather than broad multivitamin coverage.
Strengths and trade-offs
Drawn from this product's published specifications.
- 500 mg full spectrum milk thistle per capsule
- 100 count bottle
- Full spectrum extract, not an isolated silymarin dose for people wanting that specific compound
- Capsule size and count only, no liquid or powder option
Performance notes
Each vegan capsule delivers a fixed 500 mg dose of full spectrum milk thistle extract, so dosing stays consistent capsule to capsule without measuring anything.
