Not all Butterbur remedies are the same and not all of them are safe. The Butterbur plant in its un-purified powder form contains natural pyrrolizidin alkaloids (PAs) which may cause liver damage or liver cancer. Preventa Migraine is PA free, we use Butterbur Root with the PA's removed from the extract via non-chemical ion exchange, which removes nothing from the extract except the PAs and 2 to 3% of its minerals, ensuring the highest quality product with less than 1 ppm of PAs. Preventa Migraine is also manufactured in our GMP certified facility located in the United States.

Riboflavin is generally considered safe, even at high doses. Riboflavin is water soluble meaning that the body does not store it and expels it via urine, often causing a bright yellow color.
