Overview
Thorne's milk thistle phytosome, formerly sold as Siliphos, is a botanical extract complex positioned for antioxidant and liver support, third-party certified and free of gluten, dairy and soy, in a 90-capsule bottle.
The phytosome form binds the milk thistle extract to phospholipids, a different delivery approach than the standard silymarin-standardized capsules found elsewhere in this category. Thorne's third-party certification is a manufacturing quality signal that some buyers specifically look for.
- 90 capsules
- Phytosome delivery form
- Third-party certified
- Gluten, dairy and soy free
Who it's for
Buyers who want the phytosome-bound form of milk thistle specifically, from a brand with third-party testing, rather than a standard extract capsule.
Strengths and trade-offs
Drawn from this product's published specifications.
- Phytosome (phospholipid-bound) delivery form
- Free of gluten, dairy and soy
- No milligram dose per capsule listed
- Phytosome formulas are typically priced above standard extract capsules
Performance notes
Phytosome technology binds the extract to phospholipids, a delivery method distinct from plain milk thistle capsules, though the data here does not include a direct absorption comparison between the two.
