Hi---Please tell me WHERE you found info that spirulina could make "some illnesses worse"---what illnesses---anything in regard to the gallbladder? Should someone with GB problems NOT take spirulina? What could happen? My sister, who is a total vegetarian, started taking CHLORELLA and took it for only 10 days, got deathly ill--vomiting, nausea, dizzziness and had to stop it. Thanks.
