Krill and Cobalamin drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Krill (krill oil) and Cobalamin (vitamin b12). Common drug interactions include tachyphrenia among females and atrial tachycardia among males.

The phase IV clinical study analyzes what interactions people have when they take Krill and Cobalamin. It is created by eHealthMe based on reports of 14 people who take the same drugs from the FDA, and is updated regularly.
