   Over-supplementation may cause kidney stones, impaired absorption of other minerals, or cardiovascular risks.

4. Green Tea Extract

   Popular for weight loss, excessive amounts are linked to liver toxicity.

5. Kava Kava

   Used for anxiety, high doses have been attributed to severe liver injury.

6. St. John’s Wort

   This herb can cause serotonin syndrome or photosensitivity when misused or overdosed.
