what are side effects of kelp supplements?
Sue F on Aug 6, 2018
BEST ANSWER: For the first 3 weeks of taking the kelp supplements I had no side effects at all. Then I started having a headache everyday for about 2 weeks. I decided to stop taking the kelp to see if maybe that was the cause of my headaches. My headaches stopped right away.
