Would these be safe for a 20 year old? My daughter has the worst periods, and can't tolerate birth control..... Brown algae sounds like its worth the try.
I give Sanum to all 3 children. Worse period can be a candida symptom, and exmykehl suppository work in the genital tract. My daughter, she is 17, does not menstruate at all, I hope, that treating candida helps with time.
If your daughter has beside worse period no illness, maybe a good diet alone helps.
Good luck!
