I recently began supplementing with fermented cod liver oil to bump my Omega 3s. Well, I had a blood panel done and my Vitamin A levels were out of whack...too high. Generally, high vitamin A is related to supplementation, so I took a closer look at my fish oil. Sure enough cod liver oil can be quite high in vitamin A. So, I'll be stopping that one. LOL From what I have read my levels should return to normal fairly quickly. I generally only supplement Vitamin D3, but strayed from the path. Lesson learned.
