"It's a standardized milk thistle seed extract capsule delivering ~600 mg of silymarin per day — the active compound with actual clinical evidence for liver enzyme support."

Consumer advice
This is a legitimate product at a fair price. If you're looking for liver support (e.g., you drink alcohol regularly, take medications that stress the liver, or have elevated liver enzymes), this is a reasonable choice. Take all 3 capsules daily as directed — don't just take 1. Important: tell your doctor you're taking it, as silymarin can interact with many prescription medications by affecting liver enzymes that process drugs. If you want better absorption, look for phospholipid-bound (phytosome) or nano-formulated silymarin products, though they cost more. For most people, this affordable standardized extract is perfectly adequate.
