new here-- Is liverlife(supplement to support liver) legal?

[Guest guest]

I am new here, I have a 2yr old son who has been doing chelation(heavy metal detoxification) for 6 months. recently his gut problem is getting worse. we wants to start scd diet soon. liverlife has been the best product for supporting liver. I have checked the ingrdients:

Certified organic or wildcrafted, whole, pure, and predigested: himmematzutake (agaricus blazei), maitake

(grifola ponderosa), milk thistle, trametes (coriolus versicolor), reishi (ganoderma lucidum),

red root (jersey tea), olive Leaf, and 18% grain neutral spirits as a preservative.

most of them look like mushroom to me(according to google photo) except milk thistle, red root and olive leaf. but 18% grain neutral spirits as a preservative is my real concern. Is grain neutral spirits Legal?Thanks,Ming
