Im interested in trying flavonoid supplement. Im running out of hope and need to try something different. Im taking fish oil now, along with a multi vitamin and iron. I tried vit D and it gave me terrible D. I tried pepermint oil capsels and it made me feel aweful, and burned when having a bowel movement. Ive tried florastor pro biotics, along with other pro biotics and they didnt agree with me. Im so frustrated! I just want to feel better!Any info on flavonoids, and where i can purchase them would be helpful. Trial and error runs my life these days.Thanks in advance!
