I have asked my new doctor (who is for once a competent person who invests a lot of time in educating herself) whether Spirulina is safe because I wanted to take it. She told me that a colleague of her had a set of different Spirulina and Chlorella tablets as well as other algae products from health food stores analyzed and that it was highly contaminated with mercury and other heavy metals. It sort of does make sense since algae are known to bind heavy metals. She said she’d never ever tell a patient to take this (and she’s not generally against alternative medicines, she does give them to people if she thinks they are useful in her opinion). Therefore I am not gonna take it.
Hope you’re doing fine, I am usually too tired to visit the forum often…
