Oyster 🦪 shell calcium
-
Does anyone remember if ray recommended oyster shells pulverised or just the calcium derived from those shells? Pretty sure it’s the former but would like to know for sure if anyone remembers.
Can’t find the wiki page of his emails anymore where i had seen the info.
(I do remember he recommended calcium from food first and from eggshells second, and oyster shells third)
Thanks in advance.
